Problems solved by technology

[0003] The touch layer can be prepared above the light-emitting layer of the display panel, such as an oc-cell touch display panel in which the touch layer is formed on the encapsulation layer. As the size of the touch display panel increases, the area of ​​the touch electrode Increase, a large capacitive load is generated between the touch electrode and the conductive layer in the display panel, resulting in failure of touch performance

Abstract

The embodiment of the invention discloses a touch display panel. The touch display panel comprises a substrate, a light-emitting device layer and a touch layer, and the touch layer is located on the side, away from the substrate, of the light-emitting device layer; the touch display panel is provided with a display area, the display area comprises a plurality of light-emitting areas arranged at intervals and non-light-emitting areas located between the light-emitting areas, a cathode layer in the light-emitting device layer is provided with at least one opening, and the opening is located in the non-light-emitting areas; the touch layer comprises a plurality of touch electrodes, and the projection of at least part of the touch electrodes on the substrate at least partially overlaps with the projection of the openings on the substrate. According to the technical scheme provided by the embodiment of the invention, the capacitive load between the touch electrode and the cathode can be reduced, and the touch performance is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel. Background technique [0002] The touch display panel has been widely used due to its advantages of display and position touch detection functions, convenient use, and good human-computer communication experience. When the user touches the touch display panel with a hand or an external object, the touch display panel can detect the touch point and drive the touch display device according to an input command to realize a specific display. [0003] The touch layer can be prepared above the light-emitting layer of the display panel, such as an oc-cell touch display panel in which the touch layer is formed on the encapsulation layer. As the size of the touch display panel increases, the area of ​​the touch electrode Increase, a large capacitive load will be generated between the touch electrode and the conductive layer in the display panel, resulting ...
