Abstract
A display panel and a display device are provided. A light-controlling component configured to adjust a signal transmitter is disposed on a light-emitting surface of the signal transmitter of the display panel, thereby allowing modulated light, emitted from the signal transmitter disposed at a predetermined included angle with respect to a bottom surface of a cover plate, to be totally reflected between a top surface and the bottom surface of the cover plate. Total reflection is interrupted at a position where a user's finger touches. Light is received and recognized by a plurality of light sensors on a sensor array after entering the display panel, thereby realizing under-display fingerprint recognition in a large area.
