At every CES show, there will be an eye-catching new technology in the color TV industry. This year's industry focus is more than HDR technology. After a year of brewing, HDR finally moved from the prototype to the market.
HDR technology stands for High-Dynamic Range, which refers to the ability to accommodate both highlight and shadow details. Simply put, the brightness details of the picture are finely processed. This technique was originally applied in the field of photo shooting.
In the field of photo shooting, HDR can achieve perfect images through a combination of photos with different exposure levels. Currently, this technology has been successfully applied in the field of television.
In the TV field, the application of HDR can greatly improve the contrast and color accuracy of the screen. The bright part of the picture will be clearer, the dark part will be more depth, and the layer will look sharper, while the color precision will make the color Both look more pure and bright.
This year's CES show also exhibited new LCD and O LED organic TVs using HDR technology. In the industry, there are different views on the application of HDR technology. Recently, Li Tinghan, vice president of sales of LGD, once said: “OLEDs do not need a backlight, they are self-illuminating structures, which can present a thin and light design, while viewing angle and color contrast. Very good. HDR will be a new trend in 2016, and OLED is the best technology for rendering HDR technology."
The reason given by OLED proponents is that each pixel of the O led panel can independently turn on and off the illumination function, even if the bright object is in close proximity to the dark black area. This capability ensures that the image is displayed without the distortion of black and high-brightness colors with significant differences in brightness, making OLED organic TV an ideal carrier for playing HDR content.
At present, OLED technology has developed to a very mature stage. Li Tinghan believes: "The WRGB 4-color technology adopted by LGD has greatly improved the brightness of OLEDs by adding white pixels, and also solved the O-size large- scale production. The problem of low yield is widening the application field of OLED. The perfect combination of OLED organic TV and HDR technology using WRGB technology is also a highlight of this year's CES exhibition.
Objectively speaking, the popularity of HDR TV will take some time. Although there is no unified standard for HDR technology in the TV industry, it is certain that the application of HDR technology is the trend of the times, and more manufacturers will follow up in the future. Promote the rapid development of HDR technology.
