LeTV split TV 4 Max70 appearance
On December 22nd, LeTV held a conference on the theme of “Super Qu Speed†in Beijing Millennium Grand Hotel. Through these three words, we believe that we have already seen some clues. Yes, at the conference, LeTV officially launched the world’s first open-loop closed-loop LeTV ecosystem based on the original, launched the world’s first glass lightguide ultra-thin smart TV super 4 Max70 and the world’s first curved ultrathin split TV 4th generation super TV Max65 Curved, LeTV also became the world's first Internet company to launch surface split TV. Because both products are lower than the production cost pricing, but also through the ecological subsidies for hardware, it can be said that LeTV led the television industry into the era of hardware-profit.
The sofa Xiao Bian also got the 4th generation Max TV Super Max70 in the first time. The new Max TV Max70 is slightly different from the previous generations in the overall design. The original Letv LOGO has a down Outstanding design, and this generation is designed in the middle of the bottom border, it looks neat and concise. The thinnest thickness of the fuselage is only 9.9mm, which is 1/3 of the thickness of the previous generation 70-inch product.

LeTV split TV Super 4 Max70 content
The content has always been the advantage of LeTV, and its own resource pool plus the resources of the public network can be said to be very comprehensive. No matter if it is a hot movie, a TV show, an animation or a variety show, the speed of updating is very fast. A lot of TV shows are on the same line as the Guardian Video Channel and can be ordered and watched at any time. During the service period, full-screen film and television members can see massive, exciting, smooth, high-definition video resources of their own library. Even if full-screen video members do not renew after they expire, they can watch on the public network.
In terms of television dramas, it mainly covers American dramas, Korean dramas, British dramas, domestic dramas, Taiwanese dramas, Thai dramas, etc. Many of the hit dramas are basically on the same line as Wei Video, and the classic shows have been online at any time. There are other things that can only be seen on Super TV and not broadcast in the set-top box. There are now more than 100,000 episodes of content that are updated and added every day. Ready to watch at any time, there is no time and area restrictions.
In terms of live sports events, LeTV also has a very comprehensive coverage of resources. All the Champions League matches, as well as the UEFA Cup and European Super Cup competitions, Serie A and Bundesliga and the Premier League Cup events can be broadcast live. Such a wonderful event is also inseparable from the professional explanation team. Huang Jianxiang, Zhan Jun, Liu Jianhong and Dong Lu have built up a powerful lineup of explanations to enjoy the fierce competition with you.
Super 4 Max70 TV (parameter picture article) is Sharp's only original tenth-generation LCD screen, 70-inch large size, integrated 3D, 4K and other advanced technologies, of which 3D FPR is not flash. Different from previous people's perception of LCD, Super 4 Max70 TV's screen can reach 85% NTSC color gamut, with 300nit brightness and 178° wide angle, to achieve the best viewing experience.
Next we will conduct a specific screen test.
The instrument used in this test is the BM-7A luminance colorimeter produced by Topcon to measure the chromaticity coordinates of the Super 4 Max70 TV in different colors, and the saturation, contrast, color temperature and color gamut are calculated according to the corresponding values ​​and plotted. The corresponding characteristic diagram. Before this test, we first let the Super 4 Max70 TV work normally for one hour and restore to the factory settings. The entire test environment is performed in the darkroom.
After our tests and calculations, the white color temperature of the Super 4 Max70 TV reaches 9586K, which is cooler than the 7500K standard color temperature; the contrast performance is excellent, 1358.5:1, which is the upper middle level in the LCD camp; from above The figure we can also see, Super 4 Max70 TV is particularly prominent in the performance of red and green, blue normal performance. From the actual display effect, this screen has reached a very high level of saturation, the overall performance is quite eye-catching.
In recent years, many people have sang LCDs, advocating that OLED is the future technology. In fact, judging from the current development trend, it is premature to discuss who replaces LCD and OLED, because both have their own expertise. LCDs are better than lower-cost and relatively mature technologies. The advantages of OLEDs are: Thinner and more energy-efficient.
Some critics commented that OLEDs have higher contrast and color gamut, and that moving images have no streaks. In fact, the addition of HDR and quantum dot technology makes LCDs have excellent image quality, especially in the color gamut. OLED. Therefore, LCDs and OLEDs will co-exist in the market for quite some time in the future. Different panels do not represent good or bad, they are just a compromise between positioning and choice.
LeTV split TV Super 4 Max70 static test
For static testing, we will test the resolution, color performance, and viewing angle and tone level reduction of Super 4 Max70 TV. Before the test, we restore all the TV's values ​​to the default, so that the screen reaches the most original state, and the characteristics of the screen can be displayed most objectively and realistically. Let's take a look at the 4K resolution test results of the Super 4 Max70 TV.
Super 4 Max70 TV's resolving power to 4K is of medium level and not very eye-catching. The 6th line of the letters shown in the upper left corner of the figure and the 5th line of the Chinese characters can also be clearly identified, but the resolution of smaller fonts The power is vague and almost impossible to identify. Lines displaying different colors are in line with the standard, with clear boundaries and vivid colors. At the same time, the sharpness recognition capability is prominent. The difference between the 4K Ultra HD and the 1080P Full HD resolution is obvious. The front details are visible, and the black and white lines are normal.
It should be noted that Super 4 Max70 TV will not be a problem in the use of the average family, and the test results are only used as a reference under extreme conditions.
In the test of hierarchical restoration, the screen of Super 4 Max70 TV also performed well. It may be due to the camera exposure, the effect is not very obvious, but in our actual test, the 32-level and 64-level grayscale are in the optimal interval, the level is obvious, the gray level is clear, and the brightness and contrast both reach the optimal state. Star 21's grayscale performance is normal, there is no case of jumping and ordering, grayscale is too sleek and soft.
Since the Super 4 Max70 TV has the top 4K panel of Sharp's tenth generation line, there is no problem in the resolution of the picture. The transition of the smoke is soft, natural, saturated and bright. The entire evening glow is full of red and yellow. The mountains also have quite a lot of details and are not covered by black.
LeTV split TV 4 Max70 hardware test
Once again, we would like to see the running points. The test software is our common entertainment rabbit V6.0. In this version, Ann Bunny V6.0 has significantly modified the running sub-project, which is more in line with the actual use of the user. Compared to V5.7.3, V6.0 test items have also been reordered, and 3D performance tests are ranked first because AnTutu believes that the demand for GPUs in the future will be greater than the demand for CPUs.
The hardware information of Super 4 Max70 TV is as follows: Qualcomm Snapdragon APQ8094 SOC: 4-core Cortex-A57+4-core Cortex-A53 CPU+Adreno 430 GPU, and 4GB LPDDR RAM+64GB EMMC 5.0 combination, 2.4GHz+5GHz dual-band MIMO dual Antenna Wi-Fi, support BLE4.1. After reading the configuration, the author could not believe it for a long time. This is no simple "flagship" can be described, look at the phone ring is also the absolute highest match, not one. Maybe a friend or a novice, not familiar with Qualcomm's nomenclature, the author here is also a simple science popularization.
Generally speaking, the combination of three letters + four digits is the naming of Snapdragon SoC chips, such as MSM8974, APQ8084, etc., where MSM is Mobile Station Modem (integrated baseband) and APQ is Application Processor Only (only Integrated AP).
The last four figures also look very regular, but only the second digit is meaningful and related to the baseband of the collocation. 0 stands for tripartite baseband, 2 stands for GSM/WCMDA, 6 stands for GSM/CDMA/WCDMA, and 9 stands for LTE and other global network formats.
For example, the SOC with the best performance today is the Snapdragon 810. The model is MSM8994. Did you think of anything? The APQ8094 is actually a Snapdragon 810 without integrated baseband. So this SOC is what kind of ability, we should also be psychologically prepared.
However, as a rule, we also need to briefly describe the APQ8094 parameters. 4-core Cortex-A57+4-core Cortex-A53 CPU+Adreno 430 GPU, Qualcomm claims 30% better than Adreno 420, but with 20% reduction in power consumption, full support for DX11.2, OpenGL ES 3.1, OpenCL1.2, and H.265 Hard solution can also output 4K signals to external devices synchronously. Almost all specifications are the highest standards. Qualcomm's highest specification SoC is well deserved.
The combination of 4GB LPDDR RAM+64GB EMMC 5.0 also makes Super 4 Max70 TV the world’s first smart TV with 4GB of memory, larger memory brings faster data processing speed, and 64GB of storage space is also better than the average smart TV’s More than a few times more storage space.
Perhaps a friend may ask, does the smart TV need such a high configuration? With the intelligentization of the TV, the functions it carries are far more than “watching videoâ€. The Super 4 Max70 TV is more like a living room multimedia terminal. Like the PS4 and the Xbox One, we can watch Blu-ray on the Super 4 Max70 TV. Video, playing big games, and more colorful content, and these are the need for strong hardware support.
In the future, we can expect that the whole family will be surrounded by television. It will be more than just “seeingâ€. There will be more expansionary possibilities, which will allow more space for the Super 4 Max70 TV.
Then announced the results, the security Bunny score also proved that APQ8094's powerful strength, performance king, deserved. This score is also worthy of video decoding, game frame rate has no meaning, in a word, 4K video, large-scale games, feel free to play.
LeTV split TV 4 Max70 local 4K test
Watching video in life occupies the vast majority of television use time, especially for friends who like to watch Ultra HD movies, local video playback is a top priority. Because Super 4 Max70 TV supports H.265 format 4K video hard solution, and there is a professional motion picture processing chip Novatek72324 blessing, such a high-standard screen also allows the author to look forward to this link.
The actual test proved that the video playback of Super 4 Max70 TV is satisfactory. Not only is it reflected in decoding capabilities, but the details of video processing are also worthy of praise.
Each video in the test has a relatively high fluency during playback, and there is no case of staging. The overall appearance is excellent. Compared with H.264, the biggest advantage of H.265 is that it can have higher transmission and higher transmission efficiency under limited bandwidth, and only need the original half bandwidth to play the same quality video.
Many of my friends have noticed that the LCD will have a smear when displaying motion pictures. In fact, this involves two concepts, refresh rate and response time. The refresh rate refers to the number of times the electron beam repeatedly scans the screen image, which is divided into a vertical refresh rate and a horizontal refresh rate. The refresh rate generally mentioned refers to the vertical refresh rate. The vertical refresh rate represents the number of redraws per second of the screen image, and is the number of screen refreshes per second, in Hz (Hertz). The higher the refresh rate, the more stable the image and the clearer the display. Conversely, the lower the refresh rate, the greater the jitter and flicker of the image.
The response time refers to the response speed of the LCD pixel point to the input signal, that is, the time required for the pixel to change from dark to light or from bright to dark. This is often heard in 16ms and 25ms. The shorter the response time, the weaker the smear effect of the dynamic picture. The general reaction time is divided into two parts: Rise time and Fall time, while the representation time is based on the sum of the two.
Refresh rate and response time As long as one indicator is too low, it will cause a drag, and these two indicators do not exist independently. The unit of response time is ms (milliseconds), 16ms is 1/0.016 seconds, and the conversion is 63 frames per second. The unit of refresh rate is Hz (hertz), 63Hz is 63 frames per second.
In general, the response time of 16ms, plus the screen refresh rate of 60Hz, Caton and smear are almost undetectable, so 60Hz is the refresh rate of most screens, of course, some advanced technology panels can be higher The refresh rate, like the Super 4 Max65 TV's refresh rate reaches 120Hz, to the greatest extent to avoid the creation of smear.
Said so much, just want to let everyone understand the cause of smearing, let us look at the dynamic effect of Super 4 Max70 TV from the actual point of view. We will intercept screenshots of dynamic video, observe the overall dynamic performance of the picture and the ability to handle details.
From the following 4K video capture, we can see that the clouds in the sky are clearer and the outlines of the edges are sharper. After zooming in, we can clearly see the minutiae and no streaks.
The cumulus above the bridge is full of layers. On-site watching is a kind of illusion of “black clouds are pushing the city to destroyâ€. It has an on-the-spot sensation and is very strong, and there is no expressiveness because the darker colors cover the details of the picture.
From the above few screenshots we can see that the screen quality of the Super 4 Max70 TV is still very good, even if the motion picture does not affect the perception of the situation such as smearing, and the details are also very good. During the test, we also observed videos of some events and the overall performance is still remarkable.
After the hand in hand, the child will be happy to seize the big screen entrance
I believe that the scenes of Jia and Li’s boss before Shenzhen’s show of love are still fresh in their memory. In that few days, the news of LeTV and TCL’s holding hands has already exploded in the news circle and the circle of friends. , The outside world already has a lot of long articles. In fact, this is a "top-down" strategic cooperation. LeTV is very eager to find a good partner and can open up the big screen market with capital communication.
In the face of increasingly fierce competition in the Internet TV market, new models and ecology are particularly important. LeTV, as the first person to play Internet TV, undoubtedly grabbed a strategic opportunity this time. As for the Internet companies that are participating in the war, it is very likely that they will gradually be squeezed out of the market by the Matthew effect of the Internet TV era. For them, the weak industrial chain integration capability and hardware and software R&D capabilities, coupled with the weak user scale, will surely face a huge bottleneck in development.
This cooperation has not only affected Internet manufacturers. For domestic traditional TV manufacturers, LeTV has enhanced its hardware and offline services. TCL is strengthening its own Internet services and Internet operations capabilities, which is equivalent to the two strengths of the joint use of two gestures to compete with others. So don’t look at the two bosses just drinking a cup of coffee, talking and laughing together to complete the hand-holding. It’s actually a long-term decision that has been made after careful consideration, and this decision has the current TV market Revolutionary.
After the marriage, it is necessary to have two people working together to run the family. The issue of giving birth to children should naturally also be mentioned on the agenda. This LeTV did not allow us to wait too long. After announcing the hand in hand, it only took 8 days to bring its own new generation of Super TV series. Compared with the previous generation of products, it can meet the needs of high-end users.
Written at the end:
LeTV split TV Super 4 Max70 conforms to the current trends and trends of large-screen TV, high-level industrial design and 9.9mm body thickness also reflects the high-end positioning of the product, the hardware is opened up to 64-bit processing Qualcomm Xiaolong APQ8094 commercial-to-TV products. For the lower than the production price, LeTV created a new user value, but also demonstrated LeTV's confidence in the entire closed-loop ecosystem.
On December 22nd, LeTV held a conference on the theme of “Super Qu Speed†in Beijing Millennium Grand Hotel. Through these three words, we believe that we have already seen some clues.

LeTV split TV 4 Max70 color performance test
Super 4 Max70 TV (parameter picture article) is Sharp's only original tenth-generation LCD screen, 70-inch large size, integrated 3D, 4K and other advanced technologies, of which 3D FPR is not flash. Different from previous people's perception of LCD, Super 4 Max70 TV's screen can reach 85% NTSC color gamut, with 300nit brightness and 178° wide angle, to achieve the best viewing experience.
Next we will conduct a specific screen test.
BM-7A Test Instrument
The instrument used in this test is the BM-7A luminance colorimeter produced by Topcon to measure the chromaticity coordinates of the Super 4 Max70 TV in different colors, and the saturation, contrast, color temperature and color gamut are calculated according to the corresponding values ​​and plotted. The corresponding characteristic diagram. Before this test, we first let the Super 4 Max70 TV work normally for one hour and restore to the factory settings. The entire test environment is performed in the darkroom.
Super 4 Max70 TV color profile
After our tests and calculations, the white color temperature of the Super 4 Max70 TV reaches 9586K, which is cooler than the 7500K standard color temperature; the contrast performance is excellent, 1358.5:1, which is the upper middle level in the LCD camp; from above The figure we can also see, Super 4 Max70 TV is particularly prominent in the performance of red and green, blue normal performance. From the actual display effect, this screen has reached a very high level of saturation, the overall performance is quite eye-catching.
In recent years, many people have sang LCDs, advocating that OLED is the future technology. In fact, judging from the current development trend, it is premature to discuss who replaces LCD and OLED, because both have their own expertise. LCDs are better than lower-cost and relatively mature technologies. The advantages of OLEDs are: Thinner and more energy-efficient.
OLED contrast LED/LCD
Some critics commented that OLEDs have higher contrast and color gamut, and that moving images have no streaks. In fact, the addition of HDR and quantum dot technology makes LCDs have excellent image quality, especially in the color gamut. OLED. Therefore, LCDs and OLEDs will co-exist in the market for quite some time in the future. Different panels do not represent good or bad, they are just a compromise between positioning and choice.
LeTV split TV Super 4 Max70 static test
For static testing, we will test the resolution, color performance, and viewing angle and tone level reduction of Super 4 Max70 TV. Before the test, we restore all the TV's values ​​to the default, so that the screen reaches the most original state, and the characteristics of the screen can be displayed most objectively and realistically. Let's take a look at the 4K resolution test results of the Super 4 Max70 TV.
4K resolution test chart
Super 4 Max70 TV's resolving power to 4K is of medium level and not very eye-catching. The 6th line of the letters shown in the upper left corner of the figure and the 5th line of the Chinese characters can also be clearly identified, but the resolution of smaller fonts The power is vague and almost impossible to identify. Lines displaying different colors are in line with the standard, with clear boundaries and vivid colors. At the same time, the sharpness recognition capability is prominent. The difference between the 4K Ultra HD and the 1080P Full HD resolution is obvious. The front details are visible, and the black and white lines are normal.
It should be noted that Super 4 Max70 TV will not be a problem in the use of the average family, and the test results are only used as a reference under extreme conditions.
Level restoration test chart
In the test of hierarchical restoration, the screen of Super 4 Max70 TV also performed well. It may be due to the camera exposure, the effect is not very obvious, but in our actual test, the 32-level and 64-level grayscale are in the optimal interval, the level is obvious, the gray level is clear, and the brightness and contrast both reach the optimal state. Star 21's grayscale performance is normal, there is no case of jumping and ordering, grayscale is too sleek and soft.
4K static picture
Since the Super 4 Max70 TV has the top 4K panel of Sharp's tenth generation line, there is no problem in the resolution of the picture. The transition of the smoke is soft, natural, saturated and bright. The entire evening glow is full of red and yellow. The mountains also have quite a lot of details and are not covered by black.
LeTV split TV 4 Max70 hardware test
Once again, we would like to see the running points. The test software is our common entertainment rabbit V6.0. In this version, Ann Bunny V6.0 has significantly modified the running sub-project, which is more in line with the actual use of the user. Compared to V5.7.3, V6.0 test items have also been reordered, and 3D performance tests are ranked first because AnTutu believes that the demand for GPUs in the future will be greater than the demand for CPUs.
The hardware information of Super 4 Max70 TV is as follows: Qualcomm Snapdragon APQ8094 SOC: 4-core Cortex-A57+4-core Cortex-A53 CPU+Adreno 430 GPU, and 4GB LPDDR RAM+64GB EMMC 5.0 combination, 2.4GHz+5GHz dual-band MIMO dual Antenna Wi-Fi, support BLE4.1. After reading the configuration, the author could not believe it for a long time. This is no simple "flagship" can be described, look at the phone ring is also the absolute highest match, not one. Maybe a friend or a novice, not familiar with Qualcomm's nomenclature, the author here is also a simple science popularization.
Dragon Snapdragon
Generally speaking, the combination of three letters + four digits is the naming of Snapdragon SoC chips, such as MSM8974, APQ8084, etc., where MSM is Mobile Station Modem (integrated baseband) and APQ is Application Processor Only (only Integrated AP).
The last four figures also look very regular, but only the second digit is meaningful and related to the baseband of the collocation. 0 stands for tripartite baseband, 2 stands for GSM/WCMDA, 6 stands for GSM/CDMA/WCDMA, and 9 stands for LTE and other global network formats.
For example, the SOC with the best performance today is the Snapdragon 810. The model is MSM8994. Did you think of anything? The APQ8094 is actually a Snapdragon 810 without integrated baseband. So this SOC is what kind of ability, we should also be psychologically prepared.
However, as a rule, we also need to briefly describe the APQ8094 parameters. 4-core Cortex-A57+4-core Cortex-A53 CPU+Adreno 430 GPU, Qualcomm claims 30% better than Adreno 420, but with 20% reduction in power consumption, full support for DX11.2, OpenGL ES 3.1, OpenCL1.2, and H.265 Hard solution can also output 4K signals to external devices synchronously. Almost all specifications are the highest standards. Qualcomm's highest specification SoC is well deserved.
The combination of 4GB LPDDR RAM+64GB EMMC 5.0 also makes Super 4 Max70 TV the world’s first smart TV with 4GB of memory, larger memory brings faster data processing speed, and 64GB of storage space is also better than the average smart TV’s More than a few times more storage space.
Strong hardware support is very necessary
Perhaps a friend may ask, does the smart TV need such a high configuration? With the intelligentization of the TV, the functions it carries are far more than “watching videoâ€. The Super 4 Max70 TV is more like a living room multimedia terminal. Like the PS4 and the Xbox One, we can watch Blu-ray on the Super 4 Max70 TV. Video, playing big games, and more colorful content, and these are the need for strong hardware support.
In the future, we can expect that the whole family will be surrounded by television. It will be more than just “seeingâ€. There will be more expansionary possibilities, which will allow more space for the Super 4 Max70 TV.
Ann Bunny runs at 82895 points
Then announced the results, the security Bunny score also proved that APQ8094's powerful strength, performance king, deserved. This score is also worthy of video decoding, game frame rate has no meaning, in a word, 4K video, large-scale games, feel free to play.
LeTV split TV 4 Max70 local 4K test
Watching video in life occupies the vast majority of television use time, especially for friends who like to watch Ultra HD movies, local video playback is a top priority. Because Super 4 Max70 TV supports H.265 format 4K video hard solution, and there is a professional motion picture processing chip Novatek72324 blessing, such a high-standard screen also allows the author to look forward to this link.
The actual test proved that the video playback of Super 4 Max70 TV is satisfactory. Not only is it reflected in decoding capabilities, but the details of video processing are also worthy of praise.
Test screenshot
Each video in the test has a relatively high fluency during playback, and there is no case of staging. The overall appearance is excellent. Compared with H.264, the biggest advantage of H.265 is that it can have higher transmission and higher transmission efficiency under limited bandwidth, and only need the original half bandwidth to play the same quality video.
Test screenshot
Many of my friends have noticed that the LCD will have a smear when displaying motion pictures. In fact, this involves two concepts, refresh rate and response time. The refresh rate refers to the number of times the electron beam repeatedly scans the screen image, which is divided into a vertical refresh rate and a horizontal refresh rate. The refresh rate generally mentioned refers to the vertical refresh rate. The vertical refresh rate represents the number of redraws per second of the screen image, and is the number of screen refreshes per second, in Hz (Hertz). The higher the refresh rate, the more stable the image and the clearer the display. Conversely, the lower the refresh rate, the greater the jitter and flicker of the image.
The response time refers to the response speed of the LCD pixel point to the input signal, that is, the time required for the pixel to change from dark to light or from bright to dark. This is often heard in 16ms and 25ms. The shorter the response time, the weaker the smear effect of the dynamic picture. The general reaction time is divided into two parts: Rise time and Fall time, while the representation time is based on the sum of the two.
Refresh rate and response time As long as one indicator is too low, it will cause a drag, and these two indicators do not exist independently. The unit of response time is ms (milliseconds), 16ms is 1/0.016 seconds, and the conversion is 63 frames per second. The unit of refresh rate is Hz (hertz), 63Hz is 63 frames per second.
In general, the response time of 16ms, plus the screen refresh rate of 60Hz, Caton and smear are almost undetectable, so 60Hz is the refresh rate of most screens, of course, some advanced technology panels can be higher The refresh rate, like the Super 4 Max65 TV's refresh rate reaches 120Hz, to the greatest extent to avoid the creation of smear.
Said so much, just want to let everyone understand the cause of smearing, let us look at the dynamic effect of Super 4 Max70 TV from the actual point of view. We will intercept screenshots of dynamic video, observe the overall dynamic performance of the picture and the ability to handle details.
From the following 4K video capture, we can see that the clouds in the sky are clearer and the outlines of the edges are sharper. After zooming in, we can clearly see the minutiae and no streaks.
Test screenshot
The cumulus above the bridge is full of layers. On-site watching is a kind of illusion of “black clouds are pushing the city to destroyâ€. It has an on-the-spot sensation and is very strong, and there is no expressiveness because the darker colors cover the details of the picture.
Test screenshot
From the above few screenshots we can see that the screen quality of the Super 4 Max70 TV is still very good, even if the motion picture does not affect the perception of the situation such as smearing, and the details are also very good. During the test, we also observed videos of some events and the overall performance is still remarkable.
After the hand in hand, the child will be happy to seize the big screen entrance
I believe that the scenes of Jia and Li’s boss before Shenzhen’s show of love are still fresh in their memory. In that few days, the news of LeTV and TCL’s holding hands has already exploded in the news circle and the circle of friends. , The outside world already has a lot of long articles. In fact, this is a "top-down" strategic cooperation. LeTV is very eager to find a good partner and can open up the big screen market with capital communication.
Jia boss and boss Lee drinking coffee
In the face of increasingly fierce competition in the Internet TV market, new models and ecology are particularly important. LeTV, as the first person to play Internet TV, undoubtedly grabbed a strategic opportunity this time. As for the Internet companies that are participating in the war, it is very likely that they will gradually be squeezed out of the market by the Matthew effect of the Internet TV era. For them, the weak industrial chain integration capability and hardware and software R&D capabilities, coupled with the weak user scale, will surely face a huge bottleneck in development.
LeTV "Super Qu" conference
This cooperation has not only affected Internet manufacturers. For domestic traditional TV manufacturers, LeTV has enhanced its hardware and offline services. TCL is strengthening its own Internet services and Internet operations capabilities, which is equivalent to the two strengths of the joint use of two gestures to compete with others. So don’t look at the two bosses just drinking a cup of coffee, talking and laughing together to complete the hand-holding. It’s actually a long-term decision that has been made after careful consideration, and this decision has the current TV market Revolutionary.
Super 4 Max70 pricing
After the marriage, it is necessary to have two people working together to run the family. The issue of giving birth to children should naturally also be mentioned on the agenda. This LeTV did not allow us to wait too long. After announcing the hand in hand, it only took 8 days to bring its own new generation of Super TV series. Compared with the previous generation of products, it can meet the needs of high-end users.
Written at the end:
LeTV split TV Super 4 Max70 conforms to the current trends and trends of large-screen TV, high-level industrial design and 9.9mm body thickness also reflects the high-end positioning of the product, the hardware is opened up to 64-bit processing Qualcomm Xiaolong APQ8094 commercial-to-TV products. For the lower than the production price, LeTV created a new user value, but also demonstrated LeTV's confidence in the entire closed-loop ecosystem.
