Abstract

According to the driving method and the driving device of the display panel and the display device disclosed by the invention, the refresh rate of the to-be-displayed frame picture is acquired, and when the refresh rate of the to-be-displayed frame picture is not the highest refresh rate, the pre-stored corresponding RGB brightness correction table is called according to the refresh rate of the to-be-displayed frame picture, and the gray scale of the to-be-displayed frame picture is adjusted, and then the to-be-displayed frame image after gray scale adjustment is output, when the refresh rate is not the highest refresh rate, different refresh rates correspond to different RGB brightness correction tables, and the different RGB brightness correction tables are used for adjusting the output gray scales of the RGB sub-pixels when refresh rates in the same gray scale are switched so as to keep display brightness balance. Different RGB brightness correction tables are called when the refresh rates in the same gray scale are switched, the output gray scales of the RGB sub-pixels in the to-be-displayed frame picture are adjusted, display brightness balance under different refresh rates is kept, then the picture flicker phenomenon during refresh rate switching in the same gray scale is eliminated, and the product quality and the user experience are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, a driving device and a display device of a display panel. Background technique [0002] Liquid Crystal Displays (LCDs) have the advantages of low radiation, small size, and low energy consumption, and are widely used in electronic products such as notebook computers, smart flat-panel TVs, and smart phones. [0003] With the development of display technology, existing liquid crystal displays support multiple refresh rates, and the refresh rate refers to the number of times the display screen is refreshed per second. Nowadays, due to the continuous development of the e-sports field, more and more gamers have higher and higher requirements for monitors. Therefore, the existing liquid crystal display generally supports a power-saving mode with a refresh rate of 48 Hz, a daily use mode with a refresh rate of 60 Hz, and a game mode with a refresh rate of 144...
