摘要

对显示面板非对称伽马调整对残像影响的理论和相关机理进行分析，通过实际面板的残像评价验证了非对称伽马调整对残像的影响。通过实际的验证结果发现，相较于灰阶127通过调整不同的灰阶电压中心来补偿跳变电压的差异，直流残留引起的残像得到显著改善。其中短、中、长期残像的等级平均分别下降2，0.8，0.6。结果充分表明，通过非对称伽马调整的方式可有效改善直流残留引起的残像。此方案可应用于实际产品中以降低残像发生的风险和等级。

Abstract

The theory and related mechanism of asymmetric gamma tuning effect on image sticking of display panels are analyzed. The effect of asymmetric gamma tuning on image sticking is verified by evaluation of the actual panel. The actual verification results show that

the area image sticking caused by the DC residual is significantly improved by adjusting the different gray scale voltage centers to compensate for the difference of the kickback voltage compared with the gray scale 127. The levels of short

medium and long-term image sticking decreased by about 2

0.8 and 0.6 respectively. The results fully show that the area image sticking caused by DC residual can be effectively improved by the asymmetric Gamma adjustment method

which can be applied to actual products design to reduce the risk and grade of area image sticking.
