Title:
DISPLAY SCREEN, ELECTRONIC DEVICE AND FINGERPRINT RECOGNITION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/104241
Kind Code:
A1
Abstract:
Provided in the present application are a display screen, electronic device and fingerprint recognition method. The display screen is provided with a display area; the display screen is provided with multiple pixels and multiple capacitors arranged at intervals in the display area; each of the capacitors is opposite to the area between two adjacent pixels. Each of the capacitors is used to generate a fingerprint ridge detection signal corresponding to a fingerprint ridge area or to generate a fingerprint valley detection signal corresponding to a fingerprint valley area. By providing the multiple capacitors in the display area of the display screen, each of the capacitors being opposite to the area between two adjacent pixels, the capacitor and the pixel are enabled to be independent of each other, so as to ensure that the display screen can use the multiple pixels to perform normal display. The multiple capacitors can detect the fingerprint ridge detection signal and the fingerprint valley detection signal to achieve recognition of the fingerprint image of the user, thereby enabling the display screen to attend to carry out both a display function and a fingerprint recognition function in the display area, and so the screen-to-body ratio is increased.
