Abstract

The invention discloses a display panel and a display device. The display panel comprises data lines, a pixel driving circuit, a light-emitting device and a voltage compensation circuit. The pixel driving circuit comprises a data signal input end and an output end, the data signal input end of the pixel driving circuit is connected with the data line, and the output end of the pixel driving circuit is connected with the light-emitting device; the voltage compensation circuit comprises a sampling and conditioning unit; the first switch unit comprises a control end, an input end and an output end; the control end of the first switch unit is connected with the output end of the sampling and conditioning unit, and the input end of the first switch unit is connected with the output end of the pixel driving circuit; the compensation unit comprises an input end and an output end, the input end of the compensation unit is connected with the output end of the first switch unit, and the output end of the compensation unit is connected with the data line. And the compensation unit generates compensation voltage to the data line according to the driving current of the pixel driving circuit, sothat the ghost phenomenon of the display image is eliminated and the display effect is improved.

Description

technical field [0001] The present invention relates to display technology, in particular to a display panel and a display device. Background technique [0002] Display panels are widely used in modern electronic devices. Organic Light-Emitting Diode (OLED) display panels have advantages such as self-illumination and wide viewing angle, and are considered to be the next-generation display technology. [0003] However, during the display process of the OLED display panel, image sticking may occur, which affects the display quality of the display panel. Contents of the invention [0004] The present invention provides a display panel and a display device to realize the compensation for the afterimage phenomenon of the display panel and improve the display effect. [0005] In a first aspect, an embodiment of the present invention provides a display panel, which includes a data line, a pixel driving circuit, a light emitting device, and a voltage compensation circuit; [000...
