Problems solved by technology

[0003] In the process of display panel design, due to the existence of special-shaped areas (such as the grooves on the mobile phone panel for setting the camera and earpiece, etc.), such as figure 2 As shown, when the GOA 104 distributes the scanning signal line 101 to the special-shaped area or the data driving circuit 105 distributes the data line 103 to the special-shaped area, the number of pixels corresponding to each row of the scanning signal line 101 or each column of the data line 103 is different, It will cause the capacitance on the TFT 102 corresponding to the pixel on each row of scanning signal line 101 or each column of data line 103 to be different, so that there are differences in the delay of signal transmission on each signal line, so that the transmission signal is not uniform, and then affects The uniformity of picture display; in the prior art, the compensation capacitance 106 of a plurality of double-layer plates can be set on the signal line corresponding to a small number of pixels to reduce the capacitance difference between different signal lines, but a larger wiring space

Abstract

The application discloses a display panel and a display device. A compensating capability of a compensation capacitor is increased in the same area occupied in the direction perpendicular to the arraysubstrate, so the time for a signal output from a driving circuit to each row of pixels is in the same, and / or, the time for the signal output from the driving circuit to each column of the pixels isin the same so as to improve the uniformity of signal transmission. The display panel provided comprises an array substrate, and the array substrate comprises a plurality of pixels arranged in an array, and a first signal line and a second signal line for providing signals to the plurality of the pixels. The array substrate is characterized in that the number of the pixels corresponding to the first signal line is smaller than the number of the pixels corresponding to the second signal line; and the compensation capacitor is disposed on the first signal line, the compensation capacitor comprises at least three pole plates, and one of the pole plates overlaps with orthographic projections of the other two pole plates on the array substrate.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The array substrate of the display panel is provided with crisscross scanning signal lines and data lines, and the scanning signal lines and data lines enclose pixel units, and each pixel unit is provided with a thin film transistor (TFT, Thin Film Transistor) and a pixel electrode.
