We know that DLP technology has a wide range of market opportunities, bringing different application innovations to the enterprise, personal electronics, industrial and automotive markets, and even wearables with extremely high requirements on component size, performance and power consumption. Devices are the target of DLP chips. Having a wearable device with projection function is expected by many people. In the 3D field, DLP technology also has a wide range of applications, and now there are many innovative products, such as 3D printing, 3D machine vision and 3D scanning, which are the focus of DLP technology. An important market area that must not be missed is of course medical care, which is also explained in detail below.
With the rapid development of science and technology, the application of electronic technology, which is closely related to the medical level, has become more and more widespread. Medical devices with medical electronic technology as the forerunner have developed unprecedentedly, and the application of medical electronic instruments in hospitals has become more and more popular. Especially in the fields of visual diagnosis, home medical electronics, medical care, diagnostic equipment, medical electronic chips, etc., the market has broad prospects. The new market brings new opportunities to DLP technology, covering a wide range of medical imaging equipment, spectral analysis, medical health, therapeutic equipment, surgery, etc. Applications such as 3D imaging, vascular imaging, 3D measurement, dental scanning, etc. are all DLP A typical representation of technology in the field of medical applications.

According to Ms. Mariquita Gordan, Manager of DLP Embedded Projection Division of Texas Instruments, TI also has great expectations for the Chinese market, and continues to invest huge amounts of money and technology in DLP, hoping to bring more DLP innovations. Achieve more new application opportunities. Last year, the evaluation module NIRscan 4500 was introduced. With the DLP4500 package, another new DLP NIRscan was introduced this year. The near-infrared display can help customers to do some spectral analysis applications. The DLP NIRscan evaluation module is the first optimization. DLP chipset for near-infrared light technology. This development kit supports fast, programmable mode rates and digital switching through the use of reliable reflective microelectromechanical system (MEMS) micromirror technology. DLP NIRscan EVM meets the needs of designers for high-performance, economical near-infrared spectrometers for factory and field use, especially in the medical field with good technical foundation and application prospects.
In the near-infrared spectral range, many substances, whether liquid or solid, have a characteristic spectrum of the characteristic spectrum and some specific wavelengths of light, which can reflect its characteristic spectrum very strongly. Very fast detection, such as the authenticity of the drug, the composition of the drug, and whether the substance is contaminated. It is believed that the introduction of spectral analysis products for different application fields will be seen in 2015, which will be a major opportunity for DLP NIRscan.
The new DLP NIRscan can help customers explore new areas of spectral analysis. The principle is that the splitting prism splits the white light into different wavelengths and evenly projects it onto the panel. The DLP chip can control the panel to turn on the corresponding micromirror and turn the light at a certain frequency. Project onto the object, and then compare the algorithm to determine what kind of substance it is. This can be applied to many applications such as drug testing that require resolution of the material of the object.
For example, "vascular imaging" is one of the typical applications of Texas Instruments' digital light processor (DLP)-based spatial light modulator (SLM) development work platform. The device is illuminated by near-infrared light on the patient's skin to illuminate the vein, which is absorbed by the blood and reflected on the surrounding tissue. After the reflected image is processed, the infrared sensor is used to find the vein position and is projected onto the skin by DLP, so that the vein is clearly displayed.

Ms. Mariquita Gordon also said that there are many other applications in the medical field, such as skin testing, skin moisture content, and dryness, which can be used to create innovative products through spectroscopy applications. Especially worth mentioning is light therapy. Some patients with skin diseases need to be treated with ultraviolet light, but ordinary treatment methods can not be used to illuminate specific areas. DLP-optimized illumination can solve this problem.

Another very important medical application of DLP technology is dental scanning. Using DLP's 3D measurement technology, the pen device is placed in the mouth to scan the mouth and measure the 3D image of the teeth. Then according to this 3D image, the shape of the braces can be formed in the computer, thereby eliminating the process of plaster modeling. In contrast, this dental scan with DLP technology is much faster than the traditional method.

It can be said that the use of DLP technology in medical electronic products can help medical personnel to more easily implement related operations, so as to reduce patient suffering or save time in the process of related operations, especially in medical fields such as spectral analysis and digital exposure. The DLP chipset and related technologies have great advantages.
