Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0042] As mentioned in the background technology, the existing display panels tend to have brightness deviations, resulting in poor display effects of OLED display panels. The inventors have found through research that the reason for this problem is that display panels are usually subjected to high-temperature aging before leaving the factory. During the test, the TFT device characteristics of the display panel will shift during high-temperature operation, that is, the sub-threshold swing increases, and the increas...

Abstract

The embodiment of the invention discloses a driving method, a driving device and a display device of a display panel. The driving method of the display panel includes: acquiring the to-be-displayed luminance of each pixel unit of the display panel; wherein, the pixel unit includes at least three sub-pixels with different light emitting colors; determining the luminance segment corresponding to the to-be-displayed luminance to determine The gamma value corresponding to the brightness to be displayed, wherein different brightness segments correspond to different gamma values; the display gray of each sub-pixel included in the pixel unit is determined according to the gamma value and the brightness to be displayed order. The embodiment of the present invention reduces the brightness deviation of the display panel and improves the display effect of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a driving method, a driving device and a display device of a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panel is a self-illuminating display panel. Compared with liquid crystal display panel (liquid crystal display, LCD), OLED display panel does not require a backlight source, so OLED display panel is lighter and thinner In addition, OLED display panels also have the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and are increasingly used in various high-performance display fields. [0003] However, the existing OLED display panels are prone to luminance deviations, resulting in poor display effects of the OLED display panels. Contents of the invention [0004] The invention provides a driving method, a driving device a...
