Abstract

The invention discloses a display panel and a display device. The display panel comprises an array layer, a luminescent device layer and a light-sensitive device, wherein the array layer is located atone side, away from a display face of the display panel, of the luminescent device layer; the luminescent device layer comprises a plurality of organic light-emitting devices, each organic light-emitting device comprises a positive pole, a luminescent layer and a negative pole, and a film where the negative pole is located is a cathode layer; the light-sensitive device comprises a plurality of induction units, the induction units are located at one side, away from the display face of the display panel, of the cathode layer; a display area of the display panel comprises a luminous zone and non-luminous zone, the cathode layer is provided with a plurality of opening holes, the opening holes are located in the non-luminous zone, and the orthographic projections of the induction units are atleast partly located in the opening holes. The display panel and the display device have the advantages that the light penetration rate of fingerprint identification detecting is improved, thereby increasing the amount of light received by the induction units, and improving the precision of the fingerprint identification detecting.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. Fingerprints are inherent and unique to everyone, and the use of fingerprint recognition functions can improve the safety factor of the display device. When a user operates a display device with a fingerprint recognition function, the user can perform authorization verification by touching the fingerprint recognition sensor of the display device with a finger, which simplifies the authorization verification process. [0003] The existing fingerprint identification technology is divided into two types according to the setting position of the fingerprint identification sensing unit: the external type and ...
