Problems solved by technology

[0002] Existing touch screens with pressure detection include electrodes for detecting the touch position and electrodes for detecting the pressing force. The electrodes for detecting the pressing force occupy the volume of the touch screen, resulting in a large thickness of the touch screen, which is not convenient for the thinness of the touch screen. design

Abstract

The invention discloses a touch screen which comprises a compound electrode layer, a reuse electrode layer and a piezoelectric film. The compound electrode layer comprises a plurality of induction electrodes and a plurality of first pressure induction electrodes, and the induction electrodes and the first pressure induction electrodes are alternately arranged. The reuse electrode layer comprises a plurality of reuse electrodes arranged at intervals, the reuse electrodes can serve as drive electrodes and can also serve as second pressure induction electrodes, the drive electrodes are used for forming first capacitors with the first induction electrodes and used for acquiring position information pressed on the touch screen, and the second pressure induction electrodes are used for forming second capacitors with the first pressure induction electrodes and used for acquiring pressing force information pressed on the touch screen. The piezoelectric film is arranged between the compound electrode layer and the reuse electrode layer, and charge generated when the piezoelectric film deforms is picked by the first pressure induction electrodes and the second pressure induction electrodes located at the two sides of the piezoelectric film in a coupling mode to be used for acquiring the pressing force information pressed on the touch screen. The invention further discloses an electronic device.

Description

technical field [0001] The invention relates to a display technology, in particular to a touch screen and an electronic device with a pressure-sensing function. Background technique [0002] Existing touch screens with pressure detection include electrodes for detecting the touch position and electrodes for detecting the pressing force. The electrodes for detecting the pressing force occupy the volume of the touch screen, resulting in a large thickness of the touch screen, which is not convenient for the thinness of the touch screen. design. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention provides a touch screen and an electronic device. [0004] A touch screen according to an embodiment of the present invention, the touch screen includes: [0005] The combined electrode layer includes a plurality of sensing electrodes and a plurality of...
