Abstract

The present application provides a display panel driving method, a display device and a driving device; the method obtains a standard driving voltage value of a target pixel when displaying target content according to a standard gamma value of the display panel, and obtains a corresponding value of the standard driving voltage value. The target driving voltage interval, then according to the standard gamma value, the standard driving voltage value, the driving voltage value of the interval end point of the target driving voltage interval and the corresponding speckle removal parameter, determine the effective driving voltage value of the target pixel when the target content is displayed, and finally , drive the display panel to work according to the effective driving voltage value of all target pixels in the display panel; this method sets the standard gamma value corresponding to the panel for the display panel, instead of using a unified gamma value for all display panels as in the prior art , which alleviates the technical problem of uneven display caused by the use of uniform gamma values ​​in current display panels.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel driving method, a display device and a driving device. Background technique [0002] The brightness uniformity of the display panel during use is one of the important indicators to measure the display effect of the display panel. When the display panel is in use, various pollution spots will appear due to uneven brightness, which will lead to a decrease in user comfort. This phenomenon that the brightness distribution of the display panel is uneven during use and affects the image quality is called Mura ( spot). [0003] When the current display panel drives the pixels to display, it will adopt a uniform gamma value, and provide the corresponding driving voltage according to the light intensity that the pixels need to achieve. For example, when the pixels reach the same light intensity, the driver chip will provide the same However, since differen...
