Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate and a color film substrate disposed oppositely, and a light sensing recognition component comprising at least one light sensing unit and at least one upper collimating hole, wherein the array substrate comprises a first substrate and light sensing units located on one side of the first substrate close to the color film substrate, the upper collimating holes are disposed on the color film substrate and have dislocations with the light sensing units in the direction perpendicular to the display panel; and the display panel further comprises an astigmatism structure, which is located on one side of the first substrate away from the light sensing units. The display panel and a display device provided by the invention can ensure the sensitivity of the detection of the light sensing units and the accuracy of the detection of fingerprint recognition.

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. [0003] Existing fingerprint recognition technologies are further divided into capacitive fingerprint recognition and optical fingerprint recognition. The integration of optical fingerprint recognition into the display panel to realize fingerprint recognition in the display area of ​​the display panel is a research hotspot at present. At present, the research on the organic light-emitting display panel for the application of the fingerprint recognition ...
