摘　　要：针对液晶电视时序控制器T-CON(Timing Controller)中影响图像显示的色彩参数调试过程繁琐、效率低问题,根据平板电视色度学原理使用VC++编程实现了颜色校正表的自动生成,利用MSChart控件和截屏函数实现了色度坐标曲线的自动生成和保存功能。自动调试方法较传统手工调试有较大改进,效率大大提高、通用性强和色度坐标曲线一致性好。缩短了时序控制器的开发周期,改善了液晶电视图像的显示效果。Color parameters are stored in LCD TV＇s timing controller that affects the quality of image displayed.Determination of color values is a miscellaneous and inefficient process.Based on the Flat Panel TV＇s chroma theory,a method of color correction table automatic generation is realized by using VC＋ ＋.Automatic generation and preservation of chromaticity coordinate curves are realized by using MSChart control and screen capture function.A great improvement is made by the automatic debugging method to the conventional manual debugging with its characteristics of high efficiency and conformance to specification is guaranteed by strong commonality and chromaticity coordinate curves.The design cycle of timing controller is shortened by the method with the display quality improved.
