摘要
提出了一种应用于驱动频率变动的TFT LCD面板光学校正方法。首先基于时序、电压(V_(GH)/V_(GL)/V_(COM))对驱动频率变动的TFT LCD面板光学性能的影响,进行时序和电压的优化,然后通过T-Con ACC光学补偿功能,对最小与最大驱动频率下的光学数据差异进行补偿,降低频率变化时面板的光学波动。对比了校正前后驱动频率变动状态下的TFT LCD面板的光学稳定性。实验结果表明:光学校正后的TFT LCD面板在驱动频率变动时,可表现出更高的光学稳定性。
An optical correction method applied to VRR TFT LCD panel was proposed.Based on the influence of timing and voltages(V_(GH)/V_(GL)/V_(COM))on the VRR TFT LCD panel optics,the two parameters were optimized.T-Con ACC optical compensation function could be used to correct the optical data differences between minimum rate and maximum rate,thus reducing the optical fluctuation of the panel during the refresh rate.The experimental results showed that the VRR TFT LCD panel showed better optical performance after optical correction.
