Abstract

The invention provides a display device and a method for improving the brightness uniformity of the display device. The display device comprises a display panel and a processing device, wherein the display panel comprises a power voltage detection module, the power voltage detection module is used for detecting the direct current voltage drop of the display panel and inputting the direct current voltage drop to the processing device to be processed; the processing device outputs a compensation voltage of a data signal voltage of the corresponding position of the display panel according to the direct current voltage drop, and the data signal voltage of the display panel is corrected through the compensation voltage. The invention discloses the method for improving the brightness uniformity of the display device.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a display device and a method for increasing brightness uniformity of the display device. Background technique [0002] With the rapid progress of display technology, semiconductor element technology, which is the core of the display device, has also been greatly improved. For existing display devices, Organic Light Emitting Diode (OLED) is a current-type light-emitting device, because of its characteristics of self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. And it is increasingly being used in the field of high-performance display. OLED can be divided into PMOLED (Passive Matrix Driving OLED, passive matrix driving organic light emitting diode) and AMOLED (ActiveMatrix Driving OLED, active matrix driving organic light emitting diode) according to the driving method. Because AMOLED display has low manufactu...
