Abstract

The invention discloses a display panel, a touch detection method thereof, and a display device, which belong to the field of display technology and include: a display area and a non-display area surrounding the display area; the non-display area includes a binding area, and the binding area includes a plurality of The pad; the display area includes a plurality of touch electrodes, a plurality of touch lines, and a plurality of photosensitive elements; the display area includes a first area and a second area, and the second area is located on the side of the first area close to the binding area; A plurality of touch electrodes are located in the first area, and a plurality of photosensitive elements are located in the second area; the display panel includes a touch stage, and in the touch stage, the touch electrodes detect the touch operation in the first area and determine the touch operation The light sensing element detects the touch operation in the second area and determines the position of the touch operation. Compared with the prior art, the problem of high voltage of the touch electrodes that are closer to the binding area can be solved, so that the split-screen phenomenon can be improved and the display quality of the display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a touch detection method thereof, and a display device. Background technique [0002] With the development of display technologies, the functions of display devices are becoming more and more abundant, not only having display functions, but also integrating functions such as touch sensing and fingerprint recognition. [0003] figure 1 It is a structural schematic diagram of a display panel provided by the prior art. Such as figure 1 As shown, the display panel has a display area 01 and a non-display area 02, the non-display area 02 includes a binding area 021, and the binding area 021 is usually used for binding a chip or a flexible circuit board. [0004] The display panel provided in the prior art has a touch sensing function and can identify touch position information. However, when the display panel executes the display function, the scr...
