Abstract

The invention provides a display panel, a display device and a compensation control method of the display device. The display panel comprises a first signal line, a second signal line, compensation resistors, control switch tubes and a controller, wherein one of the first signal line and the second signal line is used for being connected with an input end of a direct-current power supply, and the other one is used for being connected with a power supply voltage feedback path; a plurality of compensation resistors are provided, and the plurality of compensation resistors are connected in series on the first signal line; the control switch tubes correspond to the compensation resistors, and the control switch tubes are used for controlling access states of the corresponding compensation resistors; and the controller is used for controlling on and off of the control switch tubes. Therefore, according to the display panel, the display device and the compensation control method of the invention, possible transverse stripes with non-uniform brightness can be reduced, and the display effect can be improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a display device and a compensation control method for the display device. Background technique [0002] The power supply methods of the display panel include DC power supply and AC power supply. Among them, the display panels applied to electronic devices such as mobile phones and tablet computers are usually powered by a DC power supply. In some application scenarios, the display panel powered by a DC power supply, Horizontal stripes with uneven brightness and darkness may appear, which will affect the display effect. Contents of the invention [0003] Embodiments of the present invention provide a display panel, a display device, and a compensation control method for the display device, so as to solve the problem that uneven brightness and dark horizontal stripes affect the display effect. [0004] In a first aspect, an embodiment of the present invention provid...
