Abstract

The embodiment of the invention provides a display panel drive method which is characterized in that the display panel has at least three groups of gamma curves, and the maximum grayscale of each group of gamma curves corresponds to different brightness. The drive method comprises the following steps: receiving a frame to be displayed; calling the corresponding gamma curve according to the maximumbrightness in the frame to be displayed; and generating the corresponding display information based on the corresponding gamma curve and transmitting the display information to the corresponding sub-pixels. Multiple groups of gamma curves corresponding to different brightness are included, and the corresponding gamma curve is called according to the brightness information of the frame to be displayed so that the color accuracy of the display panel is high and the situation of color cast of the display panel is prevented.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel driving method, a driving system and a display device including the same. 【Background technique】 [0002] In the prior art, the brightness of the sub-pixels is usually adjusted by adjusting the data signal, and then the color is displayed through the ratio of the brightness of the three sub-pixels of red, green and blue. In the case of low brightness, noise usually occurs, which greatly reduces the display effect, affects the user experience of consumers, and cannot be recognized by customers. The inventor finds that the brightness can be adjusted by adjusting the duty cycle to avoid noise. But at the same time, the color will shift significantly, resulting in inaccurate displayed colors. 【Content of invention】 [0003] In view of this, an embodiment of the present invention provides a driving method to solve the above technical problems.
