2.TFT液晶显示屏的工作原理(工作过程)注:目前液晶屏透光性能有两种不同类型的屏:第一种是在电极板上不加电压时,屏幕是亮的,在电极板上加电压时,屏幕是黑的;第二种是在电极板上不加电压时,屏幕是黑的,在电极板上加电压时,屏幕是亮的。这两种屏在构造上仅是两块偏振片的偏振轴
2.TFT LCD screen works (working process) Note: At present, there are two different types of LCD screen light transmission performance: The first is the voltage on the electrode plate, the screen is bright, the electrode plate When the voltage is applied, the screen is black; the second is that the screen is black when no voltage is applied to the electrode, and the screen is bright when a voltage is applied to the electrode. Both screens are constructed so that they are only the polarizing axes of two polarizers
