Embodiment Construction

[0051] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0052] OLED, also known as organic electro-laser display, organic light-emitting semiconductor. Because OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast ratio, low power consumption, and extremely high response speed, users are more and more fond of OLED screens.

[0053]Green-emitting OLEDs are the most efficient devices because the human eye is most sensitive to green light. Devices doping Alq with coumarin have an e...

Abstract

Embodiments of the invention disclose a brightness compensation method, a display and a computer storage medium. The brightness compensation method is applied to the display; a pixel back plate of thedisplay is provided with holes; and a substrate of the display is provided with a detection device. The brightness compensation method comprises the following steps: after a driving current is accessed, reflected light corresponding to light-emitting pixels is detected through the detection device to obtain reflected light parameters corresponding to the reflected light; real-time parameters corresponding to the light-emitting pixels are obtained according to size parameters corresponding to the holes and the reflected light parameters; and the driving current is adjusted according to the real-time parameters so as to carry out brightness compensation.

Description

technical field [0001] The embodiments of the present application relate to the field of flat panel display technology, and in particular, to a brightness compensation method, a display, and a computer storage medium. Background technique [0002] In the range larger than one pixel, the phenomenon of uneven brightness when displaying a pure grayscale image is called the Mura phenomenon in the industry. Mura is originally a Japanese word. With the widespread use of Japanese liquid crystal displays all over the world, this word has become a common standard in the display industry in the display industry. The Mura phenomenon has become a bottleneck restricting the development of displays. [0003] At present, in the production process, the probability of occurrence of the Mura phenomenon can be reduced by improving the technological level or improving the purity of raw materials; for displays that have been manufactured and whose physical characteristics have been finalized, t...
