摘　　要：阐释了数字电视系统部分视频参数的确定,比较了RGB,RGBYe和RGBW三种液晶电视显示屏的像素结构、像素形状、像素分布和像元分布。指出了显示屏与UHDTV信号格式不同所需格式变换将损伤图像。最后,分析了3种显示屏在色明度、色域、能效和重显HDR图像方面的性能。In this paper, how to determine some parameters of digital TV systems is studied. It compares three ultra-high definition LCDs including RGB, RGBYe and RGBW in terms of their pixel structure and shape, and pixel and subpixel distribution. The image deterioration eaused by conversion from UHDTV signal to LCD format is also analysed. The different performance on color brightness, color gamut, energy efficiency,and HDR image display for the three LCDs has further been investigated.
