In addition to showcasing a high-resolution LCD for tablets, Samsung again teamed up with Nouvoyance to bring a display for HDTV that enables noticeable power savings. The new technology combines frame sequential color (FSC), PenTile technology and RGB local dimming that produces wide range of colors, eliminates color breakup and consumes just 25 percent power compared to current LCD TV technology.
Samsung says with the help of this combination they’ve managed to get a wider color gamut display with higher power efficiency that could be instrumental in production of new generation HDTVs with good picture quality.
Samsung and Nouvoyance have been able to blend fixed color filters with clear subpixels of FSC using a PenTile RGBCW (red, green, blue, cyan, and white) color filter array. A 2D dimming RGB backlight has been highly localized to work in conjunction with the PenTile RGBCW array. The PenTile technology’s white (W) subpixels are clear and capable of crisply transmitting Red, Green, or Blue light from the backlight as needed in any given display zone. Color breakup is nearly eliminated when the color primaries are independently chosen for each zone to minimize field-to-field color excursions of the FSC display. Algorithms have been developed to analyze images, calculate gamut mapping, determine subpixel rendering and control the backlight. These techniques will be demonstrated for both still and video images. For this technology demonstration, a 15.1-inch 816 x 490 LCD is used, but the panel can be readily scaled to larger sizes and finer resolutions.
