At the CES 2017, the "center of gravity" of major TV brands returned to quality and sound quality from smart applications. After all, on the large screen of TVs, the quality and sound quality are the core of the irreplaceable.
After Sony's Z9D achieved its peak in the LCD TV field, it began focusing on OLED TVs. This is a very exciting news for many cable powders. Before knowing that the debate between OLEDs and quantum dots will become the "king of the next-generation display technology" has not yet reached a conclusion, Sony, which has a very high voice in the technical field, is likely to completely change color TV due to the release of OLED TV A1. The current pattern of the market. The two flagships are sailing and it is cool to listen.
In fact, whether it is an OLED or a quantum dot, the essence behind its technology is to enhance the display strength of the screen. Then for consumers, whoever can maximize the display capability of the screen is the "king of the future display technology." So, for Sony TVs that have created countless shining moments, whether the newly-released Sony OLED TV A1 can continue to glorify its past glory as the Chairman and CEO of Sony (China) Co., Ltd. Mr. Gao Qiaoyang said in two different ways. What is the best performance on the technology line?
I think that numerous powdered iron powders and friends are looking forward to witnessing how A1 has performed in the end. Well, China National Grid has got A1, and all the old editors have done a good job to brush up and eat at night. Give you the first-hand evaluation!
A1's biggest suspense is that the screen sounds in the end. How can it be achieved? So, put the machine in order. We must listen to the sound of A1 for the first time! The answer is: it's not the same! It's not the same! Same! The important thing is to say it three times.
A horned TV has a number of sound units. No matter where it is located, it is an N-point sound source. The sound of the A1 is a rush to the surface. There has never been a TV sound that has such a feeling. Believe that it will surpass the imagination of many people, A1's voice is very flexible, and the sound field feels wider than a horned TV. The best part is that the stereo effect is first class and there is no sound directionality because there is no speaker. For example, if there is a car whistle across the entire screen, the sound sensation is always from the front of the car. With the movement of the screen, the presence is very strong. The treble is better than the bass, don't forget, the back of the fuselage with a subwoofer on it, so the entire range is still very full.
On the other hand, flat sound is not new in itself. The principle of A1 is similar to that of the "resonance sound" of previous years, to the now popular bone conduction headphones, and to the pressure-sensitive ceramic speakers used in a concept mobile phone. However, the Acoustic Surface technology onboard A1 is called "black technology" because it achieves a high-quality surround sound effect on the basis of plane sound, and can be achieved with 4KHDR. Strong sense of presence, this is still the "first time" in the field of large-screen television.
Sony's screen sound field technology is how to do it? Figure 1 is to drive the OLED panel sound unit, they are located in the TV screen in Figure two two locations, there are two groups. Resonating with the vibrating unit with the panel sounds seemingly simple, but it takes a lot of research and development staff to work hard.
Sony also used OLED to make the top quality, followed by A1's actual image quality. Let's look at the objective parameters first, and then the actual feelings.
We use the SPIDER 4 TV colorimeter for Sony OLED TV A1 to perform color gamut testing. The test software uses DisplayCAL. Before the test, the TV is set to the factory state, and the "standard" display mode is selected and kept on for more than one hour. During the test, it is ensured that no obvious ambient light changes occur. Because the test has inevitable errors, the results are for reference only.
As a result of the test, the color gamut area of ​​A1 reached 151.9% of the Rec.709 color gamut, covering 98.8% of the Rec.709 range. This result has basically reached the top level of the industry, as a high-end OLED TV, satisfactory.
In the current era of 4K HDR, only the wide color gamut is not enough. In particular, OLED TVs have always been criticized for inaccurate colors. Will Sony OLED TV A1 not appear?
SPIDER 4 test results show that the average color deviation of the Sony OLED TV A1 is only 0.85, and the color accuracy is very high. It seems that the Z9D with the X1 Advanced Edition chip with OLED power amazing.
(E is a measure of color accuracy. Generally speaking, it is difficult for human eyes to distinguish between two colors when E is less than 3. For reference, the screen E value of consumer-grade mobile phones, computers, and monitors on the market is less than two. Already a very good level.)
Although A1's objective scores are excellent, the delicate light and shadow changes brought about by HDR effects are difficult for the instrument to express. Therefore, we still analyze the picture quality of Sony OLED TV A1 through specific examples.
A1's screen gives people the most outstanding feeling is still delicate and accurate color performance. The OLEDs that we have been in contact with before, although the color gamut is covered with Sony OLED TV A1 between Bozhong, but the color of the real picture is obviously different from the same level of LCD TV. A similar situation did not appear on the Sony OLED TV A1. Sony OLED TV A1's screen gives a clear "Sony" taste. In the color tuning style, it is in line with the previous BRAVIA, it will not appear too cool and sharp, nor because the saturation is too high, the picture is too bright and distorted.
Of course, the OLED's iconic black field performance is most commendable. Sony's OLED TV A1 is naturally very good. The black part is extremely deep, especially the dark part of the dark part, there are details that can be said that Sony uses its own chip to give The dark details of the OLED have taken a big step forward. Why we can do this, follow-up we will be X1 advanced chip for detailed interpretation of the screen processing.
It is undeniable that Sony's OLED TV A1 did not reach the "glare" level of Z9D in peak brightness, so the effect of HDR is not the same as Z9D. This is also determined by the display principle of LCD and OLED. Contrast, in short, is the lightest and darkest contrast. To achieve high contrast, there are actually two ways to go. Otherwise, the peak brightness is very high, so that the dark part is not very high can also achieve high contrast; In addition, the dark part is darker, so that the peak brightness does not need thousands of nits, but also can achieve high contrast. A1's performance is the latter. At this stage, OLED also does not achieve a full range of LCD beyond, and in the Sony's product line, Z9D and Sony OLED TV A1 is also at the flagship position. What kind of HDR picture you like is what you need to feel for yourself. The same OLED panel why Sony can do better all the performance finished, and finally we analyze, Sony in the end did what OLED?
At the CES press conference, Kazuo Hirai commented: In fact, the picture quality of television is divided into two dimensions. One is the analysis and processing capabilities of image signals, and the other is the presentation capabilities of technologies and panels. Sony is always the strongest TV manufacturer in image processing capability. This should be understandable. The pros and cons of OLED technology are believed to be clearly visible to the pros. The suppliers of OLED panels are very simple, and most of the panels in the market are out of his hands. In the case of a consistent panel dimension, image quality processing technology is the deciding factor.
If the dynamic backlight system - Master Edition and X1 Advanced Edition image processing chip is the Z9D's two magic, then the OLED has completely used less than the backlight, and of course the A1 will also carry the X1 advanced version of the image processing chip, then What can he do on OLED?
This chip performs precise repair and optimization of image signals in terms of color, sharpness, and HDR. Let's take a look at how the X1 Advanced Image Processing chip works. After the signal source is input, it will enter the signal analyzer and signal processor synchronously. The analyzer will detect and analyze the image based on the object, and output the result to the signal processing. Device to partially correct and optimize the original signal. After the signal processor sends the signal to the panel driver, it does not complete the task. The panel's feedback will be sent back to the processor. After being optimized, it will be sent to the driver display again. This will exceed the brightness information of the panel display capability. It will not be abandoned. This feature is especially important for OLEDs. The problem of insufficient OLED brightness persists. With such an algorithm, the brightness information is compressed on a year-on-year basis, ensuring no loss of detail in the HDR standard.
Another technique that must be mentioned is the HDR dynamic item-by-item remodeling technique. The advanced version X1 can detect and analyze each object of the picture and give the best optimization algorithm. Note that instead of each frame, each object, such as people, trees, and clothes in each frame, is individually detected and optimized. After individual optimization, the chip also adjusts the overall contrast of the frame. To achieve a more natural level. After such two rounds of optimization, the television can exhibit extremely realistic light and shadow effects, and various shade contrasts, gradual changes in light intensity, and even halo performance are vivid.
Using this map as an example, TV can identify the lighting effects of clothes, trees and fences in the distance, and optimize and synthesize signals separately. The brightness of the new output signal is significantly more.
Occasionally, even a 4K source will appear unclear, which is usually due to the camera's noise. The image on the screen is the original image or noise. It is easy to distinguish between the human eye and the human brain, but this may not be the case for a television set. The dual-image database provided by the X1 Advanced Image Processing IC relies on Sony's huge resources to analyze the foreground and the background. The background image is mainly based on noise reduction, and the foreground image is mainly based on detail reconstruction.
The theory is here to talk about, after all, the picture quality is to look with the eye, when comparing the OLED TV with the same panel, A1's detail performance and depth of field effects are better. In addition, if the input signal is SDR rather than HDR signal, the advantage of A1 is even more obvious, not to mention, it is also the advantage of the X1 advanced image processing chip and algorithm.
With emotion, ten years ago in 2007, not to mention OLED, Sony BRAVIA brand has just started; ten years later, with the Z9D ascended to the top of Sony, do not change the heart, once again make a mighty domineering OLED TV, there is quite a This kind of intriguing historical reincarnation.
The pursuit of the ultimate simple craftsmanship has been well designed. After the emotion is finished, the value of appearance is, after all, there are not a few people in the appearance association. But no matter what kind of "control", will be deeply impressed with the design of A1.
This year is the first year of television without borders. Major manufacturers have narrowed the TV frame on new televisions. However, whether it is from the time of release or the final product performance, Sony is in the front.
The positive aspect of A1 can be said to be a purely frameless design. If you borrow the copy of the mobile phone industry, you can call it a full screen. This shocking design, in addition to the breathing lights used to identify the on-state and receive signals, is still in the "ancestral" position, all positive elements of the interference screen are removed or weakened, the radical means and even the Sony logo are placed on The corner is in a very inconspicuous position.
This is popular with the fuselage front logo plus marquees, and then the support technology is just a clear stream of the TV industry. This not only reflects Sony's design strength, but also highlights its strong confidence in its own brand influence and appeal.
The design on the back of A1 is equally impressive. The A1's back panel uses a rare glass material on the TV to provide a visual sense of depth and highlight the theme of technology. The back of the fuselage also uses a minimalist design. The only one that is more eye-catching is the number of “small irons†outstretched on the back. These two decorative strips not only play a fixed role, but more importantly, A1's core black technology one of the screen sound field vibration module is installed, it can be said that they also assume the duties of traditional TV speakers. The BRAVIA logo stamped above declares A1's status as an OLED TV.
The A1 uses a non-pedestal design and the screen is fully supported by the back outstretched support. However, the role of the bracket is not only that, but the TV's main board, interfaces and other components are hidden in it. The upper part of the TV is even equipped with a subwoofer to enhance the bass performance of the TV. It can be said that the back bracket is complementary to the front surface, and they are organic components that are simple to ultimate without borders and without base design.
In addition, A1 also supports the design of cable storage and integration, all wires are drawn from under the bracket. Sony also designed a cover for the A1's back. Due to the design of the subwoofer on the stand, the inside and outside materials of the cover are similar to the audio cover. The sound effect can be further enhanced, and the cover is even more integrated.
After the vernier caliper test got a TV thickness value of 7.21mm, it can be seen that Sony pays more attention to the sturdiness and stability of the screen itself. After all, the design of the fuselage is enough stunning. Of course, the thickness of A1 is still satisfactory for consumers who pay more attention to product thinness and craftsmanship.
The greatest feeling of A1's design is "make the best use of it." The best way to achieve extremely simplified design is to allow every element of the body to perform as many functions as possible. So we see this A1 that integrates external functions to the extreme, not only achieving the perfect sense of science and technology and simplicity. Convergence also implicitly conforms to the philosophical thought of "If it is not necessary, do not increase the entity".
Sony's content and features have improved A1's currently used Android 6.0 operating system, but according to Sony's spring press conference. In the near future, A1, Z9D, and 9300E can all be upgraded to Android 7.0 through firmware, and Dolby Vision can be supported. In addition, HDR10 and HLG are two supported formats. A1 can be said to be the current mainstream HDR format.
The entire operating interface is still very "Sony", a high school cold children. However, with a very easy-to-handle, clearly categorized, there are many parameters that can be adjusted at the screen and sound setup level. With personalized settings, you will surely find the picture you prefer.
In terms of content, Sony has been cooperating with HUAHUA and can provide consumers with a variety of online content including movies, TV dramas, news, and variety shows to meet consumer demand for video content on demand. Sony is actively strengthening the localization of high-quality content and further expanding its entertainment resource matrix. Sohu Video, LeTV Sports, QQ Music and other domestic strong content resource suppliers have reached in-depth cooperation with Sony. This is the best content that Sony is pursuing, and it must be practiced with the best quality and sound quality television. .
In order to enhance the product's control experience, Sony OLED TV A1 has added a powerful voice function. Consumers only need to use voice to easily control the TV. In order to verify the convenience of the product in terms of voice, Xiao Bian also specifically found a number of Colleagues have a voice experience. After some experience, the conclusion is that in a relatively noisy environment, the voice recognition rate of Sony OLED TV A1 is still very high, which is a great help to the daily manipulation of consumers.
Conclusion: As the industry's benchmark product, the first appearance of the Sony OLED TV A1 equipped with many cutting-edge technologies is perfect. In addition to the ultimate quality performance, the unique process design, unique features and extraordinary sound performance allow Sony OLED TV A1 won praise from the editors, although the market price of the product has not yet been announced, but the excellent performance and the forward-looking nature of OLED TV, I believe that many audio and video enthusiasts will be inspired by it, do not worry, according to inside information Say, A1 will start booking soon.
PS: It's all said. If you want a top TV, you're buying Z9D or A1. Please ask yourself to wring it for a while because we don't know ^_^
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
