Display panel brightness adjustment method and storage medium

Abstract

The invention provides a display panel brightness adjustment method and a storage medium. The brightness adjustment method comprises a preparation step, a setting step, a database establishment step,an acquisition step, an adjustment step and an output step. According to the invention, attenuation information of the display panel is obtained according to attenuation data of the center and the edge of the display panel (through external compensation detection or data estimation and other methods), a brightness adjustment gain coefficient graph is obtained; the brightness gain coefficient of the display panel is processed; when the service life of the display panel device is not seriously attenuated; the effect of reducing power consumption is achieved by setting a large difference value ofbrightness gain coefficients at the center and the edge; and when the service life of the device at the central position is seriously attenuated, the gain coefficient is adjusted, and the brightnessdifference between the middle area and the edge is reduced, so that the service life attenuation condition of the device at the corresponding position is improved, and the service life of the displaypanel is prolonged while brightness adjustment is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for adjusting brightness of a display panel and a storage medium. Background technique [0002] Active-matrix organic light-emitting diode (Active-matrix organic light-emitting diode) display is a new type of display technology, and its continuous development and progress have brought increasingly rich display products; [0003] Due to the process and manufacturing process, the characteristics of the display are not uniform, and uniformity compensation is required; and during the display process, the drive unit and light-emitting unit such as TFT devices or AMOLED devices will have characteristic drift, resulting in non-uniformity of the display. deterioration, it is also necessary to detect and compensate for the characteristic drift of the device; [0004] For the characteristic drift of the device in the AMOLED display, the industry has also developed a variety of c...

AI Technical Summary

Problems solved by technology

The existing brightness adjustment schemes mostly use fixed brightness adjustment coefficients. After long-term use, the attenuation of the AMOLED pixels in the middle area of ​​the display panel is serious, and there may be a serious problem of life attenuation differences. The existing methods will continue to worsen the problem.

[0005] Therefore, it is urgent to provide a new brightness adjustment method and storage medium of the display panel, which can ensure the brightness adjustment of the display panel and solve the problem of device deterioration in the middle area of ​​the display panel.
