Abstract

The invention provides a display panel and an electronic device, the electronic device comprises the display panel, the display panel comprises a display panel main body, a protective layer, a light source module and an optical sensor, emergent light emitted by the light source module enters the protective layer along a first direction, the included angle between the first direction and the thickness direction of the display panel is larger than the critical angle of the emergent light on the light emitting face of the protective layer, so that the light emitted by the optical module are totally reflected in the protective layer. When a finger used for fingerprint detection touches any area of the display area of the main body of the display panel corresponding to the protective layer, the light irradiated to the finger can be reflected to the optical sensor, so that the fingerprint identification range under the display panel and the electronic device can be enlarged, and the convenience of fingerprint identification is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and an electronic device. Background technique [0002] In recent years, with the development of electronic technology, mobile display electronic devices such as mobile phones and tablets have become indispensable social media and information storage carriers in people's daily life. For such products, while pursuing fashionable appearance features such as portability, full screen, and thinness, there is also a strong demand for personal privacy protection. Fingerprint recognition has been widely used as an identification method for mobile electronic devices, and has corresponding legal effects. [0003] At present, the mainstream fingerprint identification technologies are capacitive and optical. The capacitive type is basically applied to a liquid crystal display (LCD), and is usually located on the back, lower frame or side of the electronic device. ...
