摘要

为了改善彩色液晶显示器件的色差，提升画面品质，针对（128，192，192）灰阶图形下色差的问题，对色差产生的机理进行了分析。模拟了RGB三色像素透过率对该图形下色差的影响。通过分别调整RGB彩膜膜厚，不仅相对调整了三色像素下的液晶盒层厚，而且还调整了三色像素的透过率，改善了RGB的Gamma曲线，对色差进行了补偿优化。实验结果表明，增加G像素和减小B像素的液晶盒层厚，对色差有明显补偿改善效果；同时，当RGB膜厚保持不变时，色差与液晶层厚呈正比关系，液晶层厚每减小1%时，色差约降低0.2。当RGB三色液晶盒层厚从（3.47，3.38，3.4） m分别调整到（3.5，3.45，3.36） m和（3.5，3.44，3.28） m时，（128，192，192）灰阶图形下样品色差平均值从13.8分别降低到12.8和12。通过分别调整RGB彩膜膜厚，相对调整了三色像素下的液晶层盒厚和液晶量调节，可以一定程度优化补偿色差。

Abstract

In order to improve the chromatic aberration in color LCD device and enhance the display quality

the effect of RGB transmittance on chromatic aberration was simulated for a particular pattern of(128

192

192) gray scale. By respectively adjusting the thickness of RGB film

not only the relative cell gap of RGB was tuned

but also the transmittance of RGB was adjusted to improve RGB gamma curves

and chromatic aberration was compensated and optimized. Experimental results show that the increase of G and the decrease of B in cell gap

can obviously improve chromatic aberration. Meanwhile

when the thickness of RGB keeps no change

chromatic aberration is proportional to cell gap of liquid crystal. Cell gap reduces by 1%

chromatic aberration correspondently decreases about 0.2. When the cell gap of RGB changed from(3.47

3.38

3.4) m to(3.5

3.45

3.36) m and(3.5

3.44

3.28) m

the average chromatic aberration of sample was reduced from 13.8 to 12.8 and 12 in the pattern

respectively. Thus

chromatic aberration can be compensated by separately adjusting the relative thickness and cell gap of RGB.
