HDR TV will become the main theme of this year's color TV technology upgrade

About 10 years ago, the "high dynamic range rendering" technology, which was abbreviated as HDR, became a professional circle for photo enthusiasts. With the full support of HDR camera functions, Apple's seventh-generation smartphone products made it even more popular in the past year. Fans are eagerly pursuing the focus. In 2016, TV products with the concept of HDR appeared on the market as high-end technologies, and OLED TVs and high-backlight TV products lifted them to the same high-level promotional status as “4K”. HDR is not a new technology that was invented in recent years. As early as 2004, Fujifilm introduced a high dynamic range SuperCCD SR. Half of the pixels are used to record the normal brightness, and the other half is used to record the dark position of the screen. Its digital SLR S3 Pro. In 2005, the famous photo design software Photoshop launched HDR-compatible features. HDR has gradually become popular in SLR cameras and image post-processing software. HDR originally was only a static image processing technology. With the development of technology, HDR technology is gradually used in display devices as a dynamic picture processing technology. When the audience compares ordinary photography images with HDR effect images, the stunning effect of the latter gives viewers a "shocking shock." When viewing HDR static images, the performance of the HDR static images is reflected in their high level of detail and vivid contrast. It is very rich, as if people who have been watching the world for twenty years have brought myopia glasses for the first time. HDR photos are highly regarded for giving people a new visual experience, but at the same time because of the unnaturalness of the exposure, it is considered by some people to be contrary to the "real" demands. Although HDR and HDR are not exactly the same concept, consumers have the same confusion: HDR rendering of dynamic video requires dual cooperation between the chip and the highlight screen, depending on the HDR algorithm and decoding chip that are added to the driver. The HDR source is correctly decoded and played, while the high-brightness screen can display the processed image closest to the original. For some 4K resolution screens, personalized algorithm support is also needed to avoid overexposure. HDR TVs have different picture effects, mostly due to hardware and content. The HDR environment of the trinity of screens, chips, and content can be called a real HDR TV. In addition, currently HDR is divided into two popular standards: HDR 10 and Dolby Vision. There are no absolute advantages or disadvantages between the two standards. However, many manufacturers will only show that they support HDR video content, but do not specifically describe what they support. Which standard is intended to mislead consumers. This led to the HDR TV supporting the HDR 10 standard, which has absolutely no "lightening" effect when playing Dolby Vision standard video. In view of the misleading practices of individual color enterprises and consumers' perceptions of the concept of HDR, the purchase of HDR-enabled TVs did not allow full playback of HDR sources, resulting in many complaints of “pseudo-HDR TV”, but with the After the HDR Display Technology Certification Specification was issued, HDR TV standards have become more standardized after HDR technical requirements for input signals, high dynamic range, color gamut coverage, peak brightness, and black brightness. At present, due to the large amount of HDR data, HDR has a high requirement for transmission bandwidth. However, in view of the popularity of bandwidth development in the past two years, HDR transmission concerns are not the biggest problem. The biggest obstacle that HDR TV currently faces is still the problem of fewer consumer film sources. The effect of non-HDR film sources on HDR TVs is basically the same as that of ordinary TVs. Most of the video resources played on the online shopping mall are commercial HDR resources, and HDR video resources are still generally less used in actual daily viewing. At present, foreign video sites such as YouTube and Netflix can already broadcast HDR video on demand. In China, the first domestic HDR system brought by Skyworth's penguin TV with Tencent can view Warner 4K HDR content. However, from a technical point of view, the technical barriers to the popularity of HDR are relatively small, and it is not as difficult as upgrading the panel hardware. The reason is that the HDR content is not affected by the resolution. As long as there is a matching algorithm chip, whether 4K, 1080P or even 720P can play back HDR standard content. And compared to the improvement of the visual sensation brought about by the resolution, the improvement of the picture details and gradation effects brought about by the resolution is even more obvious. This is the reason why HDR is popular today. The HDR source may be somewhat backward, but from the perspective of its promotional environment, it is difficult to achieve rapid adoption. "Although there is a dispute between the backlight and the self-illuminating schools in the technical competition of color TV products," the color TV industry source explained to the home network that "High Dynamic Range Rendering HDR technology can be applied across the two platforms, which is why 2017 The reasons for the full popularity of the technology among the color TV companies' collectively planned new products. In addition, the HDR bailout cost is only the chip and algorithm patents, but there is a huge increase in the margin rate of the new single machine. Obviously, HDR is a rare technology for consumers to promote visual perception. For TV companies, it is also a good straw to save performance.
