Abstract

The invention relates to a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate and a piezoelectric induction layer formed on the substrate, andis characterized in that the piezoelectric induction layer includes; a signal transmitting unit configured to transmit a surface acoustic wave signal; a signal receiving unit configured to receive a surface acoustic wave signal; a plurality of wire grid arrays configured to reflect the surface acoustic wave signals transmitted by the signal transmitting unit to the signal receiving unit; And the semiconductor layer array which is arranged in an area enclosed by the plurality of groups of wire grid arrays, wherein the plurality of groups of wire grid arrays are arranged to enable reflected surface acoustic wave signals to spread over the semiconductor layer array and then reach the signal receiving unit. According to the invention, the in-screen fingerprint identification of the full-screenpanel can be realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] The existing fingerprint identification technology usually detects the reflected light of the finger, and judges whether the corresponding position is a fingerprint valley or a fingerprint ridge according to the difference in light intensity of the reflected light between the fingerprint valley and the fingerprint ridge, thereby forming a fingerprint image at the corresponding position. [0003] Chinese Patent Publication No. 108052930 (CN108052930A) proposes an array substrate that can be used for fingerprint recognition. The array substrate includes: a base substrate; a piezoelectric sensing layer formed on the base substrate; a surface acoustic wave excitation electrode and a surface acoustic wave receiving electrode formed on the piezoelectric sensing layer; and a sur...
