Problems solved by technology

[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. Double impact, which requires relatively high brightness display uniformity. In the actual production process, OLED display uniformity often cannot reach the preset value

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] ...
