No need to change existing color filters to achieve similar color gamuts. Sun Qingcheng, professor of optoelectronics at Central University of Taiwan, said that the school's photoelectric center solid-state lighting team has introduced LED-backlit wide color gamut technology without changing existing color filters. The film can reach (or exceed) the color gamut of other related technologies, and only use the RGB three-color LED, which is a big breakthrough in the liquid crystal display backlight technology.
The team research group Professor Yang Zongxun proposed a new design, based on RGB LED as the backlight source, retaining the original color filter of the LCD panel, and controlling the color gamut of 122% NTSC through coordinated control of light and electricity. , approaching the theoretical limit of the current 125% NTSC color gamut of RGB LED backlights. Yang Zongxun said that this technology has made Taiwan a world-leading level in the color performance of liquid crystal displays, and has great advantages in cost and production technology thresholds, and has the potential for commercialization in the short term.
LED solid-state light source is recognized as the first glare of LCD TV's next-generation backlight source. For this reason, the global LED, panel and display related industries are actively developing LED backlight technology with high color gamut performance and practicality. In the past two years, Japanese SONY and South Korea's SAMSUNG and other large manufacturers have published a wide color gamut technology using LED as a light source, trying to achieve technological leadership in the next generation of display wars.
Sun Qingcheng said that Japanese and Korean manufacturers have the same level of color saturation, mainly removing the color filter, finishing with RGB LED timing, or adding a fourth color filter matching the amber LED. To achieve high color gamut performance; these methods generally require a large modification of the LCD panel process, and even need to develop a faster LCD display to achieve, in the short term does not have a cost advantage.
In the past three years, the research team of Taiwan University has been continuously improving its LED backlight technology. In addition to fully grasping the calculation model of LED light source model and backlight technology, it has more excellent works in color technology. Yang Zongxun said that the success of this technology is attributed to the long-term cultivation of backlight technology and the infinite creativity of the team members, in order to develop world-class technology in the absence of sufficient resources.
