不同的环境光照下相邻像素的选通态对LCD透射屏测量对比度的影响

The Influence of the Activated State in the Adiacent Pixels on Measuring Contrast Ratio in the Transmission LCD panel at Different Lighting Conditions

研究了不同的环境光照下 ,相邻像素的选通态对 LCD透射屏测量对比度的影响。结果表明 :1 .不同的照明条件下 LCD透射屏的对比度会发生很大的变化 ,但相邻像素的选通态对测量对比度的影响始终存在 ;2 .与 L CD反射屏相比 ,透射屏中相邻像素的选通态对测量对比度的影响 。

The influence of the activated state in the adjacent pixels on the measuring contrast ration in the transmissios LCD panel at different condition is studied in this paper,the result shows:1. the change of contrast ratio is large and the influence of the activated state in the adjacent pixels on the contrast ratio always exist in the transmission LCD panel different lighting condetion:2. compared with the reflective LCD panel,the influence of the activated state in the adjacent pixels on the measuring contrast ratio mainly comes from stray light than pixel shadow in the transmission LCD panel.
