Abstract

According to the display panel gamma voltage correction compensation method and device and the storage medium provided by the embodiment of the invention, the actual gamma voltage of the display panel is acquired, the first gamma voltage curve is acquired according to the actual gamma voltage of the display panel, and the built-in gamma voltage curve is matched; and then the display panel is driven to display through the built-in gamma voltage curve, so that the gamma voltage adjustment data can be directly and completely written at one time, the gamma voltage data writing time is shortened, the gamma voltage correction time is shortened, and the productivity of a display panel production line is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for correcting and compensating a gamma voltage of a display panel, a device thereof, and a storage medium. Background technique [0002] Gamma voltage is an important parameter to measure the characteristics of the display screen, which describes the degree of distortion of the output image of the display to the input image. This parameter is affected by many process parameters and materials. Specifically, the pre-tilt angle, cell thickness, liquid crystal and color resistance will all affect the gamma voltage, resulting in large fluctuations in the gamma voltage. Therefore, it is necessary to correct the gamma voltage. And with more and more requirements from customers, customers have more and more stringent requirements on the control of gamma voltage. Gamma voltage correction has become a necessary technology for display manufacturers. [0003] Among...
