Abstract

The invention discloses a display panel, a touch detection method thereof and a display device, and belongs to the technical field of display. The display panel comprises a display area and a non-display area surrounding the display area; the non-display area comprises a binding area, and the binding area comprises a plurality of bonding pads; the display area comprises a plurality of touch electrodes, a plurality of touch lines and a plurality of light sensing elements; the display area comprises a first area and a second area, and the second area is located on the side, close to the bindingarea, of the first area; the touch electrodes are located in the first area, and the light sensing elements are located in the second area; the display panel comprises a touch control stage, in the touch control stage, the touch control electrodes detect touch control operation in the first area and determine the position of the touch control operation, and the light sensing element detects the touch control operation in the second area and determines the position of the touch control operation. Compared with the prior art, the problem that the voltage of the touch electrodes close to the binding area is large can be solved, so that the split-screen phenomenon can be improved, and the display quality of the display panel is 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...
