Problems solved by technology

However, for special-shaped display panels, because the shape of the display area is irregular, the length of the signal lines in the display area will also be different.
In this way, the number of pixels that need to be driven by the shorter signal line will be less than the number of pixels that need to be driven by the longer signal line, which will lead to inconsistent trace loads of different signal lines, which will lead to different signal lines. The degree of attenuation of the signal transmitted on the Internet is different, which will have a negative impact on the display performance of the display panel.

Abstract

The embodiment of the invention provides a display panel and a display device, related to the technical field of display and used for reducing load difference of signal lines of different length. Thedisplay panel comprises an image display area and a non-image display area, the image display area comprises a first display area and a second display area; the image display area comprises pixels andfirst signal lines, wherein the first signal lines comprise a first child first signal line in the first display area and a second child first signal line in the second display area, the number of pixels connected with the first child first signal line is greater than the number of the pixels connected with the second child first signal line; the display panel comprises a capacitance compensationstructure, and the capacitance compensation structure comprises a first conductive layer, a second conductive layer and a third conductive layer; the second conductive layer is located between the first conductive layer and the second conductive layer, the first conductive layer is connected with the third conductive layer, the first conductive layer and the second conductive layer are overlapped, and the second conductive layer and the third conductive layer are overlapped; and the second child first signal line reuses the second conductive layer or the third conductive layer.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] Along with the diversified designs of display panels, special-shaped display panels have been more and more widely used. However, for the irregular-shaped display panel, since the shape of the display area is irregular, the lengths of the signal lines disposed in the display area are also different. In this way, the number of pixels that need to be driven by the shorter signal line will be less than the number of pixels that need to be driven by the longer signal line, which will lead to inconsistent trace loads of different signal lines, which will lead to different signal lines. Different degrees of attenuation of the signals transmitted on the different channels have adverse effects on the display performance of the display panel. 【Content of invention】 [0003] In view of this, the embodiment...
