Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a substrate, a plurality of scanning lines, a plurality of touch electrodes and a plurality of compensation lines. In the direction perpendicular to the substrate, the touch electrodes are overlapped with the scanning lines corresponding to the touch electrodes,and one compensation line is overlapped with the touch electrodes corresponding to the compensation line; wherein when the scanning signal of one first scanning line is the same time of the falling edge and the scanning signal of one second scanning line is the rising edge, the compensation line and the second scanning line are overlapped in the direction perpendicular to the substrate; and / or when the scanning signal of one first scanning line is the same time of the rising edge and the scanning signal of one second scanning line is the falling edge, the compensation line and the second scanning line are overlapped in the direction perpendicular to the substrate. According to the invention, the problem of abnormal display near the gap between the touch electrodes during display of the display panel in the prior art is effectively solved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] figure 1 It is a schematic plan view of a touch display panel in the prior art. The display panel includes a plurality of mutually independent touch electrodes 1, and each touch electrode 1 corresponds to a plurality of pixel electrodes (not shown in the figure), each Each touch electrode 1 is electrically connected to at least one touch wire 2 , and the touch electrode 1 is electrically connected to the driving chip 3 through the touch wire 2 electrically connected thereto. When in the display stage, the driver chip 3 provides a common signal to the touch electrode 1, and the touch electrode 1 is used as a common electrode, and an electric field is formed between the touch electrode 1 and the pixel electrode to drive the liquid crystal to deflect, so that the display panel realizes display. W...
