Display panel, fingerprint identification method thereof, program unlocking method thereof and display device

Abstract

The invention discloses a display panel, a fingerprint identification method thereof, a program unlocking method thereof and a display device. A curved-surface display region comprises a substrate base plate. A light emitting device and a protection cover plate are successively arranged on one side of the substrate base plate. Multiple optical detectors are arranged between the light emitting device and the substrate base plate. The light emitting side of the light emitting device in the curved-surface display region comprises an optical structure used for gathering light. The optical detectoris used for receiving light which is emitted by the light emitting device and reflected by a fingerprint when the finger touches the curved-surface display region of the display panel. According to the invention, the light emitting side of the light emitting device in the curved-surface display region comprises an optical structure used for gathering light, so when the finger of the user touchesthe region, the emission light of the light emitting device is firstly subjected to gathering and then shines on the finger of the user; and the energy of the light shines on the finger is quite strong, so the energy of the light reflected back to the optical detector by the finger is increased therewith, thereby facilitating improving accuracy of fingerprint identification.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, an application unlocking method thereof, and a display device. Background technique [0002] With the development of fingerprint identification technology, it has been widely used in many fields, such as mobile phones, tablet computers and TVs in electronic equipment terminals; access control and safes in security protection systems. The realization methods of fingerprint collection mainly include optical, capacitive and ultrasonic imaging technologies, among which the optical fingerprint recognition technology has a relatively large recognition range and relatively low cost. [0003] At present, mobile terminals such as mobile phones are often combined with optical fingerprint recognition technology to provide users with a more convenient and faster experience. The principle is that the light emitted from the display device illuminates the finger and i...

AI Technical Summary

Problems solved by technology

The display device usually has a certain thickness and is formed by stacking and combining multiple film layers, so the light reflected back to the optical detector is very weak. For example, the brightness of the light emitted by the display device is 200-400 nit. The brightness received by the optical detector is less than 10nit, which is not conducive to the accurate identification of fingerprints
