Problems solved by technology

[0004] However, the display brightness of the display panel when it is in AOD mode during the display panel debugging stage is different from the display brightness when it is in AOD mode during the whole machine stage, which is not conducive to controlling the quality of the display panel

Abstract

The invention relates to a display panel, a power supply method thereof and a display device. The display panel comprises a first group of power lines, a second group of power lines, a third group ofpower lines, a driving chip, a switching circuit and a light-emitting element, wherein the driving chip comprises a power supply module; one end of the first group of power lines is electrically connected with the light-emitting element, and the other end of the first group of power lines is electrically connected with the switching circuit; one end of the second group of power lines is electrically connected with the power supply module while the other end of second group of power lines is electrically connected with the switching circuit; one end of the third group of power lines is electrically connected with power supply module, and the other end of the third group of power lines is electrically connected with the switching circuit; and the switching circuit outputs a first electric signal transmitted on the second group of power lines to the first group of power lines in a screen-off display mode, and outputs a second electric signal transmitted on the third group of power lines to the first group of power lines in a normal display mode. According to the embodiment of the invention, the brightness of the display panel in the screen-off display mode in the debugging stage can be prevented from being different from the brightness of the display panel in the screen-off display mode in the complete machine stage.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a power supply method thereof, and a display device. Background technique [0002] In the related art, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices usually have two working modes: Normal mode (normal display mode) and AOD mode (Always On Display mode, always-on-display mode). Among them, the AOD mode is to minimize the display power consumption of the display panel. Therefore, except for the specified display area for displaying specified display information (such as time, calendar, etc.), the rest of the display area is turned off in AOD mode. Since the overall brightness of the display screen is low when in the AOD mode and only a partial display area is required for display, the current required by the display panel for display is relatively small. When the display device enters the AOD mode, turn off the external power s...
