Abstract

The invention provides a method for compensating the uneven brightness of a display panel and a display device. The display panel may include a plurality of display blocks, each of the plurality of display blocks may include one or more display units, and the method includes selecting a voltage detection terminal of one display block of the plurality of display blocks according to a control signal, wherein the control signal carries the information indicating the display block; generating a plurality of reference voltages according to the voltage level of the voltage detection terminal; and based on the plurality of reference voltages, driving a display voltage to a display unit in the display block according to a group of display data. According to the method for compensating the uneven brightness of the display panel and the related display device, the overall efficiency of the display panel can be improved.

Description

technical field [0001] The present invention relates to a display device, in particular to a method for compensating uneven brightness of a display panel and a related display device. Background technique [0002] In order to provide power to all the display units in a display panel, longer wiring may be required in the display panel to transmit the power supply to the display units that are far from the power supply circuit. However, the materials used to implement these wirings are not ideal conductors, so a voltage drop may occur on the wiring path and affect the brightness of the display unit. In particular, the brightness of the display units at different locations may be different. Therefore, a novel method and a related display device are needed to compensate the brightness unevenness of the display panel. Contents of the invention [0003] An object of the present invention is to provide a method for compensating uneven brightness of a display panel and a related...
