驱动电路篇 LCD的原理背光发射的光线经过滤光片变成RGB这样的三基色光,然后经过偏振片变成偏振光,通过液晶的旋光作用使得偏振光旋转,然后再经过偏振光片输出。液晶对偏振光的旋转角度不同,输出的亮度就不同,从而实现了RGB三色的亮度变化,最终生成了五彩缤纷的色彩。 Driving circuit articles LCD principle Backlight emitted by the light filter into RGB such as the three primary colors of light, and then through the polarizer into polarized light, through the optical effect of the liquid crystal so that the polarization rotation, and then through the polarizer output. LCD on the polarized light rotation angle is different, the output brightness is different, so as to achieve the RGB three-color brightness changes, and ultimately generated a colorful color.
