Title:
DISPLAY SCREEN, ELECTRONIC DEVICE AND FINGERPRINT RECOGNITION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/024561
Kind Code:
A1
Abstract:
Provided are a display screen, an electronic device and a fingerprint recognition method. The display screen comprises: a photosensitive sensor, a control integrated circuit (IC), an active-matrix organic light-emitting diode (AMOLED) display panel, a polarizing sheet and a piece of cover plate glass, with the polarizing sheet being arranged between the AMOLED panel and the cover plate glass, and the control IC being connected to the photosensitive sensor, wherein the photosensitive sensor is laid on the surface of the AMOLED panel and is arranged between the AMOLED panel and the polarizing sheet; the photosensitive sensor is used for converting, when a user's finger touches the cover plate glass, an optical signal reflected by the user's finger into an electrical signal; the photosensitive sensor is further used for sending the electrical signal to the control IC; and the control IC is used for converting the electrical signal into a fingerprint signal, and performing fingerprint recognition according to the fingerprint signal, thereby improving the screen occupation rate of an electronic device while realizing fingerprint recognition.
