| 摘 要： | 全彩色ＬＥＤ显示屏可以用来显示电视画面。目前没有专门用于ＬＥＤ彩色大屏幕的图像源及其标准，所以都是将送给ＣＲＴ显像管的图形信号源送到ＬＥＤ彩色大屏幕进行显示。针对把送给ＣＲＴ的信号送到ＬＥＤ屏进行显示会引起彩色失真这种情况，本文给出ＬＥＤ大屏幕系统的色度公式，为准确控制ＬＥＤ管的发光亮度提供理论依据，并给出产例。

| Abstract: | LED super scale color screen can be used to show TV programs.At present there is no source of images and standard used specially for LED super scale color screen,so the signal shown by LED color screen is what is sent to CRT.There exist great color distortion when we directly send the signal which is used to drive CRT to LED color screen.In view of the situation,this paper gives the formulas of chrome calculation for LED color screen,provides the theoretical basis so as to control the brightness of LED precisely,and brings out a practical example. |
