Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area, wherein the display area comprises a light-emitting area and a non-light-emitting area; the non-light-emitting area comprises a light-transmitting area and a non-light-transmitting area; the display panel comprises an array layer, a display layer, a plurality of light-sensing devices, and a polarizing layer, wherein the array layer comprises a plurality of metal lines located in the non-light-emitting area; the display layer is located above the array layer and comprises a plurality of light-emitting devices, wherein the light-emitting device comprises an anode, a light-emitting layer and a cathode, and one light-emitting area comprises one light-emitting device; a plurality of the light-sensing devices are located on one side of the array layer away from the display layer; and the polarizing layer is located on one side of the display layer away from the array layer, the polarizing layer is provided with a first opening located in the non-light-emitting area, wherein at least a portion of the first opening is located in the light-transmitting area, and the light-transmitting area is an area in the non-light emitting region where the metal line is not disposed. The display panel and the display device in the invention can improve the transmittance of the fingerprint recognition light, increase the amount of light received by the light-sensing device, and improve the fingerprint recognition precision.

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 optical fingerprint recognition technology generally detects the light reflected to the fingerprint recognition unit through the touch subject (such as a finger), that is, deter...
