Abstract

The invention discloses a touch panel, a display panel, a display device and a fingerprint identification method. The touch panel comprises a substrate, a plurality of fingerprint identification units arranged on the substrate, and an encapsulation layer covering the plurality of fingerprint identification units; and the fingerprint identification units include light-emitting devices and light-sensitive devices. In addition, the touch panel also includes optical path restricting structures arranged above all the light-emitting devices. Because of the optical path restricting structures arranged above the light-emitting devices, light emitted by the light-emitting devices is transmitted in the optical path restricting structures in a total reflection manner. Light of an emergent area is centralized in a small-angle range, so that light emitted by the light-emitting devices is sent out in a manner of quasi collimation; and thus the light irradiation range of the area of a to-be-identified fingerprint is reduced and the angles of reflected light are centralized. Most of light is irradiated on the light-sensitive devices corresponding to the light-emitting devices, so that the crosstalk of light received by the light-sensitive devices in different identification units is avoided and thus accurate fingerprint identification is realized.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch panel, a display panel, a display device and a fingerprint identification method. Background technique [0002] With the advent of the information age, people pay more and more attention to information security. Fingerprints are widely used in security encryption and information identification due to the uniqueness of the information they contain. Therefore, the development of fingerprint identification technology is also widely recognized by people. focus on. [0003] In the prior art, the fingerprint recognition in the display device is mainly realized by adding infrared light-emitting sub-pixels and fingerprint photosensitive devices on the basis of the original pixels to realize fingerprint recognition in the display area. However, in the above-mentioned recognition methods, infrared light-emitting After the light emitted by the sub-pixel is reflected b...
