Problems solved by technology

[0003] Usually, in order for the driver IC to receive touch signals from any area in the display panel, each touch electrode requires an independent lead. Such a large number of leads leads to a larger frame of the display panel and a lower screen-to-body ratio.

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display area and a non-display area, the display area comprises display scanning lines, display data lines, touch scanning lines, touch data lines, touch electrodes and touch switches, and each touch scanning line is electrically connected with the control ends of the touch switches corresponding to the touch electrodes in the same row; at least one touch control data line is electrically connected with input ends of a plurality of touch control switches corresponding to the same column of touch control electrodes; the output end of the touch switch is electrically connected with the touch electrode; In the plurality of touch switches and the plurality of display scanning lines corresponding to the same row of touch electrodes, the distances between the touch control ends of at least two touch switches and the same display scanning line are different; and/or in the plurality oftouch switches and the plurality of display data lines corresponding to the same column of touch electrodes, the distances between the touch signal input ends of at least two touch switches and the same display data line are different. Therefore, on the premise that the narrow frame is ensured, the picture display effect can be improved.

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] With the continuous development of electronic technology, display devices as one of the interaction windows between users and electronic equipment have attracted much attention. In the prior art, in order to improve user experience, the display device usually has a touch function. For a display panel or display device with a touch function, it is usually necessary to set a touch signal line so that the driving integrated circuit (Integrated Circuit, IC) can provide a driving signal for the touch layer and receive feedback from the touch layer. signal, so that the display device realizes the touch function. [0003] Usually, in order for the driver IC to receive touch signals from any area in the display panel, each touch electrode requires an independent lead. Such a large number of leads leads to a la...
