Flat panel display technology upgrade Hisense release uled 1.5 generation upgrade Products

Uled uses the multiple partition independent backlight control and the Hiview picturesque engine technology, in the picture contrast, the picture level sense, the dark detail, the color accurate restoration and the picture smoothness aspect compared with the traditional LED display has greatly promoted, its quality performance may be comparable to OLED, currently has obtained 13 invention patents, including the United States, European patent authorization.

December 16 News, Hisense officially launched Uled product upgrades, released 1.5 generation uled upgrade products. The newly upgraded ULED1.5 products are further upgraded in display technology and quality performance. ULED1.0 users can achieve 1.5-generation display technology optimization by OTA online upgrades by the end of this month, and 100,000 uled users will benefit.

Uled is a display quality technology processing engine for electronic medical display and high-end LCD TV research. March 27, 2014, Hisense launched the XT900 series of the first application uled display technology television, has 50, 55, 65 inch three size specifications. Combined with the 4K XT900 series Uled TV in the quality performance than OLED products better, and in the product pricing, Hisense 65-inch 4K uled products are less than half the price of the same size OLED products.

March 27, 2014 Uled 1.0 official release

Uled uses the multiple partition independent backlight control and the Hiview picturesque engine technology, in the picture contrast, the picture level sense, the dark detail, the color accurate restoration and the picture smoothness aspect compared with the traditional LED display has greatly promoted, its quality performance may be comparable to OLED, currently has obtained 13 invention patents, including the United States, European patent authorization. The upgraded Hisense ULED1.5 products use peak brightness high color domain module and backlight partition control and Hiview picturesque image Engine 2 generation technology, display performance compared to ULED 1.0 products further upgrade.

The display effect of LCD TV is decided by three parts, screen, backlight module and image processing technology. Because the liquid crystal itself does not glow, need to be illuminated by the backlight to be seen by the human eye, so the quality of the backlight technology on the LCD TV has a crucial impact on the picture. We can find that as long as the LCD is connected to the power, backlight is working, even if the screen is a picture of the whole black, backlight is also working, that is, LCD TV backlight is always in the glow, but we usually see the content of the television screen is a change of light and shade, In particular, the film plays a large number of dark screen, steady backlight is not conducive to dark details of the performance, ULED TV backlight control technology is to solve the LCD TV this backlight principle defects and design.

Uled uses multiple partition independent backlight control and Hiview picturesque engine technology to divide the backlight into several independent control units. Each unit can be based on the TV picture of the bright dark distribution accurately adjust the corresponding area of backlight to open, close, and the back brightness of peak adjustment, so as to achieve energy saving effect of electricity, It can make the TV black more pure, the image level is rich, the depth of the effect is outstanding. By the authority of the China Electronic Standardization Research Institute, ULED1.5 product dynamic contrast reached 8 million: 1, compared to the average 4K TV upgrade of 3 orders of magnitude, detail performance stunning.

Application of uled technology in LCD TV

More accurate expression of image detail and level sense

Although LCD TV backlight experienced a full upgrade from CCFL to LED, the LCD resolution from 1080P to 4 K, but due to the limitations of the display technology, 4K TV can not complete the table 1.07 billion color of the ideal color number. Uled uses Blu-ray chips to excite red and green phosphor or quantum dots, based on the study of spectral distribution of hundreds of LED backlight spectra and dozens of kinds of color filters, a set of simulation models for the color gamut of liquid crystal modules was established, and the best color filter and high color LED backlight spectra were designed by optimizing the experimental data of thousands of groups. Can present more color details. The detection data shows that the range of uled gamut is up to 120% of the standard value of BT.709 HD TV color gamut. Uled using narrow spectral high color domain technology, RGB three primary colors higher purity, its accurate color reproduction technology can be adaptive to the screen color processing, to protect the details of the image color expression and accurate restore. After the upgrade of Hisense ULED1.5 products designed vivid (bright) mode, in this mode users can watch more stunning image color.

In addition to the backlight control and color performance breakthrough, uled using up to 1440Hz high speed scanning system, making the liquid crystal in the rotation process in the backlight Black field scan State, reducing the image of the human eye residual feeling, to achieve a smooth motion picture.

After 10 years of rapid growth, the color TV market will enter a stable development period from this year onwards. Over the past 10 years, the form of television products from CRT to flat, from SD, HD to Super HD, the pursuit of display technology to promote the development of the core power of industrial upgrading. Hisense Uled based on independent display technology innovation in the industry to establish a benchmark, uled technology research and Development to obtain the National Council for Reform Project support, the project name is "LCD LED backlight and key materials research and development and industrialization", Also received 2014 Ministry of Professional (medical) Display Module key technology research and development and industrialization of major special support, breaking the previous major show that technological innovation by foreign enterprises led the situation. According to display Search published market data, with uled products outstanding performance, Hisense in the 4K Ultra High-definition TV market share of 9.2%, leaped to the top three in the global market.

Samsung and other brands are also actively in the quality of innovation efforts, is expected in the next few years around the display technology innovation will become a mainstream trend in the color TV market.
