Abstract

The invention relates to the technical field of display, and provides a display module, a driving method and a display device. The display module comprises a power supply output module which comprises a first power supply end and a second power supply end and is used for outputting different power supply voltages through the first power supply end and the second power supply end; a pixel driving circuit which is respectively connected with a driving voltage signal end, a data signal end and the first power supply end, wherein the pixel driving circuit is used for receiving the data voltage signal by using the power supply voltage of the first power supply end under the control of the driving voltage signal and providing a driving current; a light-emitting unit which is connected between the pixel driving circuit and the second power supply end, wherein the light-emitting unit emits light under the action of the driving current; an electric leakage protection module, wherein the first end of the electric leakage protection module is connected between the light-emitting unit and the second power supply end, the second end of the electric leakage protection module is grounded, and the electric leakage protection module is at least used for being in a conducting state when the second power supply end is closed.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a display module, a driving method and a display device. Background technique [0002] Compared with backlight displays such as LCDs, OLED displays have the advantage of low power consumption. In related technologies, when the Power output is turned off, when the Power is turned on again for display, ELVDD will recharge ELVSS, causing the ELVSS POWERIC to turn off the output after overvoltage protection, resulting in abnormal display problems such as yellowing of the display screen. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art. Contents of the invention [0004] The purpose of the present disclosure is to overcome the ...
