Abstract

A driving control method is disclosed. The method includes steps of sequentially turning on the first color sub-pixel, the second color sub-pixel, the third color sub-pixel and the white color sub-pixel respectively in the first time period, the second time period, the third time period, and the fourth time period in order to respectively input grayscale values of the sub-pixels using the source driver. Wherein, when using the source driver to input the grayscale vale of the white color sub-pixels, the source driver decreases a preset value of gamma voltages of the white color sub-pixels such that the preset value of gamma voltages when inputting grayscale values of the white color sub-pixels is less than a preset value of gamma voltages when inputting grayscale values of the first color sub-pixels, the second color sub-pixels and/or the third color sub-pixels. Through the above way, the display quality can be increased.
