METHOD, DEVICE AND SYSTEM FOR COMPENSATING BRIGHTNESS OF A LIQUID CRYSTAL MODULE |
| 摘要 |
A method for compensating the brightness of a liquid crystal module involves acquiring an image of a liquid crystal module to obtain the acquired image. The acquired image of the liquid crystal module is compared with a standard image to find a dark region. The compensation coefficient of each pixel in the dark region is calculated. In a display control circuit of the liquid crystal module, the calculated compensation coefficient of pixels is stored for compensating the backlight unit corresponding to pixels in dark region. |
