Problems solved by technology

[0004] In order to realize pressure sensing, existing products need to increase the process of making upper and lower electrode layers and insulating layers. Not only the process is complicated and the cost is high, but also the existing capacitive structure increases the thickness of the display panel.

Abstract

The invention provides a touch display panel and electronic equipment. The touch display panel comprises a substrate and a display module, and further comprises an insulating dielectric layer, a protective layer and a pressure sensing electrode layer, wherein the display module comprises an anode layer, a light-emitting layer and a cathode layer which are sequentially arranged on the substrate; the insulating dielectric layer is arranged on one side, away from the display module, of the substrate; the protective layer is arranged on one side, away from the display module, of the insulating dielectric layer; the pressure sensing electrode layer is arranged between the insulating dielectric layer and the protective layer; the pressure sensing electrode layer and the cathode layer of the display module form a capacitor structure; the capacitor structure is used for achieving a pressure sense touch function. On one hand, the cathode layer of the display module is also used as an electrode layer of the capacitor structure, and the pressure sensing electrode layer is arranged between the insulating dielectric layer and the protective layer, so that reduce in the cost and the overall thickness of the display panel can be facilitated; on the other hand, the cathode layer can well shield outside interference and only transmits a pressure signal, so that the detection on the capacitance change of the touch display panel is high in stability.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and electronic equipment including the touch display panel. Background technique [0002] Electronic products are now increasingly involved in all aspects of our lives, and touch technology, as a convenient and effective human-computer interaction solution, has become an indispensable technology in electronic products. Resistive touch screen and capacitive touch screen are the two most widely used touch screens at present. Among them, the resistive touch screen has the advantages of simple design and low cost, but it is relatively limited by physical limitations, such as low light transmittance and easy aging; the capacitive touch screen supports multi-touch function and has high light transmittance and low power consumption. The advantages of power consumption, since the launch of Apple's iPhone, capacitive touch screen has entered a period of rap...
