Abstract

The invention provides a touch assembly with pressure detection. The touch assembly with pressure detection comprises a three-dimensional sensor and a three-dimensional controller, wherein the three-dimensional sensor comprises a plurality of touch electrodes and at least one pressure detection electrode; the three-dimensional controller comprises a driver and a driving pulse processor; the driver supplies a pressure scanning pulse to the at least one pressure detection electrode and supplies a touch scanning pulse to the multiple touch electrodes under the cooperation of the driving pulse processor. The invention further provides a driving method of the touch assembly with pressure detection. The method comprises the following steps: the driver supplies the pressure scanning pulse to the at least one pressure detection electrode under the cooperation of the driving pulse processor; the driver supplies the touch scanning pulse to the multiple touch electrodes. The touch assembly with pressure detection has the advantages of simple hardware design, high integration degree, high anti-noise property, simple driving method and the like.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of touch control, in particular to a touch control assembly with pressure detection and a driving method thereof. [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 t...
