Abstract

The invention provides a display panel and a display device. The display panel comprises a display screen and a fingerprint recognition module arranged on the back surface of the display screen; the display screen comprises an array substrate and a pixel definition layer; the fingerprint recognition module is located on the side, away from the pixel definition layer, of the array substrate; an organic light-emitting layer is arranged in the pixel definition layer; a plurality of condensation through holes are formed in a non-light-emitting area of the pixel definition layer; the condensation through holes penetrate through the pixel definition layer; and condensation lenses are arranged in the condensation through holes. According to the display panel provided by the invention, due to thearrangement of the condensation through hole and the condensation lens, fingerprint reflected light rays are ensured to be refracted and converged by the condensation lens, the incident range of the fingerprint reflected light rays is enlarged, the fingerprint reflected light rays can more accurately and efficiently penetrate through the display panel and reach the fingerprint identification module, and the fingerprint identification unlocking speed is increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] OLED full-screen display panels have a larger effective display area when applied to mobile terminals such as mobile phones, providing more information display, thereby improving the human-computer interaction experience, so full-screen display panels are increasingly used in display devices . In order to maintain the existing fingerprint identification function while implementing a full display panel in the existing display panel, it is necessary to integrate the fingerprint identification module in the display area of ​​the full display screen. [0003] Usually, the fingerprint identification module is arranged under the display screen. In the working state, the light-emitting element in the display screen emits light to the outside of the screen body, and then reflects to the screen body through the ...
