Abstract

The invention discloses a display panel and a display device. The display panel includes: an array substrate and a color filter substrate arranged opposite to each other; a photosensitive recognition component including at least one photosensitive unit and at least one upper collimation hole; the array substrate includes a first substrate located on the side of the first substrate close to the color filter substrate The color filter substrate is provided with an upper collimation hole, and there is a dislocation between the upper collimation hole and the photosensitive unit in the direction perpendicular to the display panel; the display panel also includes an astigmatism structure, and the astigmatism structure is located on the first substrate away from the light sensor unit side. The invention can ensure the detection sensitivity of the photosensitive unit and the accuracy of fingerprint identification and detection.

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 ...
