Abstract

The invention provides a three-dimensional touch assembly. The three-dimensional touch assembly comprises a composite touch pressure sensing layer; the composite touch pressure sensing layer comprises a flexible substrate layer, and a first touch pressure sensing layer and a second touch pressure sensing layer arranged on two sides of the flexible substrate layer respectively; a plurality of first-direction touch piezoelectric electrodes are arranged on the first touch pressure sensing layer; a plurality of second-direction touch pressure sensing electrodes are arranged on the second touch pressure sensing layer; and the first-direction touch piezoelectric electrodes and the second-direction touch pressure sensing electrodes detect not only a touch signal but also a pressure signal. The three-dimensional touch assembly provided by the invention has the advantages of lightness and thinness, simple hardware and circuit design, low cost and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to the fields of touch and pressure sensitivity, in particular to a three-dimensional touch assembly. [0003] 【Background technique】 [0004] With the development of technology, the touch screen assembly has been widely used in various consumer electronic devices, such as: smart phones, tablet computers, cameras, e-books, MP3 players and other portable electronic products, or Applied to the display screen of the operation control equipment. [0005] Most of the existing electronic equipment adopts a capacitive touch assembly, and the capacitive touch assembly uses the current induction of the human body to work. A two-dimensional coordinate system (X, Y) is established on the surface where the touch surface is located. A general capacitive touch assembly is provided with touch electrodes in the X direction and Y direction in this plane. When placed on a touch surface, the finger alters the electrical signal at the touch...
