Abstract

The invention relates to the technical field of pressure sensing, and in particular to a pressure sensing device which can be used for detecting the pressure intensity. The pressure sensing device comprises a substrate, a conductive pattern layer and a pressure sensing signal wire, wherein the substrate comprises a first surface and a second surface; the first surface and the second surface are oppositely arranged; the conductive pattern layer is arranged on the first surface, comprises a plurality of pressure sensing electrodes and is used for sensing the touch pressure intensity; the pressure sensing signal wire is used for connecting the pressure sensing electrodes to a detection chip in a conducting manner and is of a hollow-out structure.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of pressure sensing, in particular to a pressure sensing device capable of detecting pressure strength. [0003] 【Background technique】 [0004] At present, in the field of display technology, commonly used touch panels mainly include capacitive touch panels, resistive touch panels, optical touch panels and surface acoustic wave touch panels. These types of touch panels are mainly used to detect two-dimensional The touch position of the planar area, and the processing chip feeds back the corresponding processing signal according to the touch position. Moreover, among them, the capacitive touch panel is most widely used. [0005] Finger operations on the touch panel are very rich and complex, including not only the "touch" action but also the "press" action. At present, the capacitive touch panel can only detect the position of the "touch" in a two-dimensional plane, and the The strength of "pressin...
