Abstract

A display device with a fingerprint identification function comprises a display panel which is provided with a display area and a non-display area; an ultrasonic fingerprint identification module which is arranged inside the upper surface of the display device with the fingerprint identification function and comprises a substrate; a reflecting layer arranged on the substrate; a plurality of microcrystalline particles distributed in the reflecting layer; And at least one ultrasonic wave generating and receiving unit arranged on at least one side edge of the reflecting layer.

Description

technical field [0001] The disclosure relates to a display device, in particular to a display device with a fingerprint identification function. Background technique [0002] The fingerprint recognition commonly used on mobile phones generally adopts the front button type (iPhone mobile phone) or the back capacitive type (Android mobile phone), but with the demand for full screen and ultra-thin technology, the design of the mobile phone space occupied by the fingerprint recognition is becoming more and more restricted , So various embedded fingerprint recognition technologies adapted to the full screen have been developed, such as the ultrasonic mode under the screen or the optical mode using the grating effect. [0003] However, the above technology will increase the thickness of the mobile phone, so it is necessary to propose a solution to the problems in the prior art. Contents of the invention [0004] The purpose of the present disclosure is to provide a display devi...
