Example Embodiment

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] An embodiment of the present invention provides a brightness adjustment method for a display panel, such as figure 1 shown, including:

[0051] S101, according to the set gamma curve, determine the target brightness value and the corresponding target grayscale value within the selected gamma value range;

[0052] S102. Drive the display panel with the target grayscale value, and obtain the actual luminance value of each pix...

Abstract

The invention discloses a display panel brightness adjustment method and a computer readable medium. When the actual brightness value of the display panel is determined not to meet a brightness uniformity requirement, based on the difference between a target gray scale value corresponding to a target brightness value and an actual gray scale value corresponding to an actual brightness value, the target gray scale value is compensated to obtain a compensated brightness value; and later, when the compensated brightness value is determined not to reach a set range of the target brightness value,the target brightness value is compensated again according to the above step until the latest compensated brightness value reaches the set range of the target brightness value. Through the above brightness compensation process, the uniformity of the display panel can be quickly and accurately adjusted.

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 computer-readable medium. Background technique [0002] At present, there are certain requirements on the uniformity of display brightness of flat panel display panels. For example, for electroluminescent display panels as self-luminous devices, the brightness of each area is affected by the light-emitting (EL) material and the control of the uniformity of the backplane. Due to the double impact, the requirements for the uniformity of brightness display are relatively high. In the actual production process, the uniformity of OLED display often cannot reach the preset value. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method for adjusting brightness of a display panel and a computer-readable medium for adjusting brightness uniformity of the display panel. [0004] ...
