Do you dare to believe that 4000 nits? Watch Sony TV show tricks
Television sets serve as living room entertainment centers and play an important role in each family. With the changes of the times, television has also experienced a continuation from generation to generation. If the television industry has been competing for content services in the past few years, this year is undoubtedly a return to the essence. Innovative display technologies such as HDR, quantum dots, OLEDs, and laser televisions are gradually maturing, and each TV maker has put its focus on the development path with display technology as the core.
Sony, as one of the companies that entered the Chinese market earlier, has always stressed the need to continue to bring users a sense of Sony and Sony's dual values. Sony really did manage to establish a loyal group of users in the country. The entire brand enjoyed a good reputation in the country and created excellent results. It coincides with the 20th anniversary of entering China, Sony also ushered in another important milestone in the development of the quality of television products - 4K HDR.
If you want to ask what display technology is the hottest this year, HDR is definitely one of them. Almost all TV manufacturers have put HDR as a new selling point for 2016 products. Why does HDR heat up all of a sudden? In fact, for the current video quality, there are five important dimensions: resolution, color gamut, grayscale, frame rate, and SDR. The first four dimensions have basically matured enough, except that the SDR standard has not ushered in innovation for 50 years until HDR emerges.
The birth of HDR redefined the direction of R&D for video capture, codec and imaging. In the strict sense, HDR is a standard and cannot be understood as a purely technical means. The most direct effect of HDR is to make the black display more profound and without losing details, and the brightness can be increased to a more realistic brightness, which can provide the user with a more layered picture effect and a more outstanding shadow performance, real reflection. Environmental effects.
The advent of HDR has also made the development of video technology more comprehensive and complete. Of course, it also provides room for the development of technology-driven enterprises such as Sony. At this year's CES in the United States, Sony brought a new "Backlight Master Drive" backlighting technology that can achieve a stunning 4000 nits in brightness. Why do you call it amazing degree? The brightness of a typical LCD TV is between 300-500 nits. Even the HDR-based TV products have a peak output of about 1,000 nits. This is the brightness standard that HDR will achieve. The Sony Master Dynamic Backlight system left other HDR standard TVs far behind.
We all know that LCD TVs, unlike OLEDs, are non-emissive display devices. Therefore, it is necessary to work hard on the backlight module to achieve a unique brightness range. The "Backlight Master Drive" Dynamic Backlight System Master Edition is based on a direct-lit LED backlight architecture that uses an ultra-dense, matrix-type backlight with more than 1,000 backlight partitions. In a direct-lit backlight LED TV, the more partitions, the higher the accuracy of backlight control. This kind of backlight technology that works perfectly with HDR can be realized thanks to the support of direct-lit backlight LED arrays.
We generally measure the color performance capabilities of TVs through the “gamut.†I believe that the users who have read the Zhongguancun online TV evaluation articles will have seen a color range map. In a two-dimensional coordinate system, the triangle formed by three colors of RGB represents the color performance capability. The higher the coverage rate, the higher the color gamut. However, in fact, it is more appropriate to use a three-dimensional coordinate system to represent the color gamut, but it is necessary to add a brightness dimension. This is because the color performance will also change at different brightness levels, for example, in the common In the BT709 color gamut specification or the BT2020 color gamut specification, if we add luminance information, we will find that the volume of the entire color gamut in the three-dimensional space will be very large, from a plane to a column.
After HDR is added, the brightness range of the TV is greatly expanded, and the color display capability of the entire TV is also improved. But having a wide color gamut does not mean that color performance will definitely be better. As the saying goes, "The object is extremely negative." Excessively high color gamut will make the color too bright, and colors that are too saturated to the naked eye will produce distorted effects. Therefore, it would be very difficult to achieve the desired results if we are too eager to pursue color coverage or if we do not have sufficient strength in color management.
Sony has always shown people with its black technology, and innovative technology has always been at the forefront of the world. Sony TV's color management capabilities have always been legendary in the industry. This is not only dependent on its accumulated expertise in upstream shooting and post-production, but also closely related to Sony's decades of professional TV manufacturing experience. Sony has a group of experienced image quality engineers who control from two aspects of hardware and software, adjust the color performance, ensure that the color gamut of the TV is improved, and still remain in the category that can be controlled.
The full ecological layout of HDR is also Sony's strengths. Whether it is a professional TV camera or the latest 4K digital movie camera, Sony has advanced solutions and products. This company, which has the ability to capture and disseminate full-process technologies, can naturally integrate technology advantages from the front-end to the transmission when launching display terminals such as televisions. The understanding of the professional level of the picture quality and profound technical details are the real technical scars of Sony.
