| 摘 要： | 带RGB-LED背光系统的32inAS-IPS液晶电视被开发出来了,它可以调节每个主背光源的亮度,并可以对每帧中的原像数据进行转换。红色、绿色和蓝色背光的亮度根据输入的图像数据分别进行调节。图像数据按照调节后的背光亮度进行转换。因此,动态对比度和低灰度的色域均得到很大的改善。

| Abstract: | 32-inch AS-IPS LCDs TV with RGB-LED backlight system was developed, which modulates each primary backlight's brightness and converts each primary image data in every frame. Red, green, and blue backlight brightness are modulated respectively depending on inputted image data. The image data are converted according to modulated backlight brightness. As a result, not only the dynamic contrast ratio but also the color gamut of low gray levels is significantly improved. |
