Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] Currently, if Figure 1a As shown, the touch panel 01 on the display panel includes touch electrodes 011 distributed in an array; by applying a high-voltage and high-frequency pressure-sensitive signal on the touch electrodes 01, as Figure 1b As shown, more delicate tactile feedback can be realized. Since the pressure-sensitive signal has the characteristics of high voltage and high frequency, it will generate a large electromagnetic radiation, which wi...

Abstract

The invention discloses a touch display panel and a display device. The touch display panel comprises a display panel body and a touch panel located on the light emitting side of the display panel body. The display panel body comprises a substrate, wherein the substrate comprises a display area and a non-display area located around the display area; an organic electroluminescence film layer which is located between the substrate and the touch panel, wherein the organic electroluminescence film layer comprises a cathode layer arranged close to the touch panel, and the orthographic projection of the cathode layer on the substrate covers the display area and at least part of the non-display area; a metal frame which is located between the substrate and the organic electroluminescent film layer, wherein the orthographic projection of the metal frame on the substrate is located in the non-display area, the orthographic projection of the metal frame on the substrate is at least partially covered by the orthographic projection of the cathode layer on the substrate, and the metal frame is grounded. The touch display panel can solve the splash screen problem of the display panel caused by electromagnetic interference generated by applying high-frequency and high-voltage signals to the touch panel.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a touch display panel and a display device. Background technique [0002] As consumers have higher and higher requirements for mobile phone functions, tactile feedback has been redefined. The early tactile feedback is to add touch sensors to the main board of the mobile phone to realize the vibration of incoming call messages, but the human sense of touch is a more important dimension. , so with the further development of technology, we want to achieve more delicate tactile feedback on the displayed content, such as sensing different textures, different objects, etc., to further improve the user experience of mobile phones, so we use touch sensors to increase high-voltage and high-frequency drive way to achieve tactile feedback. [0003] Because the touch sensor needs to be driven by high voltage and high frequency, it will generate relatively serious electromagn...
