Taiwan LED backlight wide color gamut technology breakthrough

Without changing the existing color filter, the color gamut of other related technologies can be achieved

National Central University Department of Optoelectronics professor Sun Qingcheng said, the school of optoelectronic Center for solid state lighting team launched LED backlight wide color gamut technology, without changing the existing color filter, can be reached (or beyond) other related technologies of similar color gamut, using only three RGB LED, is a liquid crystal display backlight technology on the big breakthrough.

The design team proposed a new research group of Professor Yang Zongxun the day before, with RGB LED as backlight based liquid crystal panel, retain the original color filter, the coordinated control of light and electricity, showing the color gamut of 122%NTSC, the theory of limit approximation today RGB LED backlight 125%NTSC color gamut. Yang Zongxun said, this technology makes Taiwan has the world's leading level in LCD color performance, cost and production technical standard has great advantages, have commercial potential in the short term.

LED solid-state light source is recognized as the next generation of LCD TV backlight preferred. To this end, the global LED, panel and display related industries are actively developing a high color gamut performance, but also practical LED backlight technology. Over the past two years, Japan's SONY and South Korea SAMSUNG and other large manufacturers have been published in the LED as a light source wide color gamut technology, trying to get the technology leader in the next generation of display wars.

Sun Qingcheng said that Japan and South Korea manufacturers at the same level of color saturation, color filter is mainly removed, to complete the RGB LED sequence of light, or increase the color filter fourth and amber, LED, to achieve the high performance of the color gamut; these methods generally require a modification of the LCD panel process, even the need to reach the development of liquid crystal display can be more rapid, does not have a cost advantage in the short term. Taiwan research team in the past three years in the LED backlight technology continues to improve, in addition to fully grasp the LED light source model and backlight technology calculation model, the color technology is more excellent. Yang Zongxun said that the success of the development of the technology to be attributed to the team members in the backlight technology long-term cultivation and the infinite creativity of students, in the case of insufficient resources to develop world-class technology.
