Abstract

An embodiment of the present application provides a method for driving a display panel, wherein the display panel has at least three sets of gamma curves, and the maximum gray scale of each set of gamma curves corresponds to a different brightness; the driving method includes: receiving the Displaying a picture; calling a corresponding gamma curve according to the maximum brightness in the picture to be displayed; generating corresponding display information based on the corresponding gamma curve, and transmitting the display information to corresponding sub-pixels. This application contains multiple sets of gamma curves corresponding to different brightness, and the brightness information of the screen to be displayed calls the corresponding gamma curve, so that the color accuracy of the display panel is high, and the 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. [0004] ...
