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

Abstract

The invention discloses a display panel, its fingerprint identification method, its program unlocking method and a display device. The curved surface display area includes: a base substrate, a light emitting device and a protective cover sequentially arranged on one side of the base substrate; the light emitting device A plurality of optical detectors are arranged between the substrate and the substrate; the light-emitting side of the light-emitting device in the curved display area has an optical structure for converging light; the optical detector is used to receive the light-emitting device when the finger touches the curved display area of ​​the display panel. The light reflected from the finger. Since the curved surface display area has an optical structure for converging light on the light-emitting side of the light-emitting device, when the user's finger touches this area, the outgoing light of the light-emitting device will first be converged and then irradiate the user's finger, and the light energy incident on the finger will be stronger. , so that the light energy reflected by the finger back to the optical detector also increases, which is more conducive to improving the 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
