Abstract

The invention provides a display device and a brightness detection method thereof, relates to the display technical field, and solves the display frame brightness uneven problem; the display device comprises a display layer, a control module, at least one brightness detection unit set on the light extraction side of the display layer; the brightness detection unit set has a plurality of brightnessdetection units; the display layer has a plurality of display units; the display unit has at least one sub-pixel; the projection of one brightness detection unit on the display layer has an overlap area with one display unit; portions, located in the overlap area, of the plurality of display units that overlap with the same brightness detection unit are same; the brightness detection units in thesame brightness detection unit set are used for detecting the real brightness data of the overlap area, and sending the data to the control module; if the comparison result between the real brightness data and the reference brightness data corresponding to the image data exceeds a preset scope, the control module obtains the brightness compensation data of the display unit according to the comparison result.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a brightness detection method thereof. Background technique [0002] In recent years, organic light emitting diodes (OLEDs) have been widely used in the field of high-performance displays due to their advantages such as self-illumination, wide viewing angle, short response, high luminous efficiency, wide color gamut, and low power consumption. [0003] However, due to various reasons, the picture displayed by the OLED display device is prone to the problem of uneven brightness. [0004] For example, when a flexible OLED display device is bent or folded, the brightness of the picture displayed in the deformed area is different from the brightness of the picture displayed in the non-deformed area; the OLED display device includes a part of the transparent display area, and the transparent display performance The requirement for pixel density (pixel per inch, ...
