Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0062] Each person's skin patterns, including fingerprints, are different in patterns, breakpoints and intersections, which are unique and unchanged for life. Accordingly, we can match a person with his fingerprints, and verify his true identity by comparing his fingerprints with the pre-stored fingerprint data, which is fingerprint identification technology. Thanks to electronic integrated manufacturing technology and fast and reliable algorithm research, optical fingerprint identification technology in fingerprint identification...

Abstract

The embodiment of the invention discloses an array substrate, a display panel and a display device. The array substrate includes: a substrate; a plurality of light-emitting units located in the display area of ​​the substrate. The light-emitting colors of the light-emitting units include a first color, a second color, and a third color, and the light transmittances of the first color and the second color are equal. The light transmittance greater than the third color; and a plurality of first-type fingerprint recognition units and a plurality of second-type fingerprint recognition units located in the display area of ​​the substrate; the light-emitting unit is used as a light source for the fingerprint recognition unit, and the first-type fingerprint recognition The configuration parameters of the unit are different from those of the second type of fingerprint identification unit, so that for the same reflective surface, the electrical signal values ​​detected by the first type of fingerprint identification unit and the second type of fingerprint identification unit are the same. The technical solutions of the embodiments of the present invention can improve the screen-to-body ratio of the display panel and the accuracy of fingerprint identification.

Description

technical field [0001] Embodiments of the present invention relate to fingerprint identification technology, and in particular, to an array substrate, a display panel and a display device. Background technique [0002] Because fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint identification function, the user only needs to touch the fingerprint identification unit of the display device with a finger to perform authorization verification, which simplifies the authorization verification process. [0003] The fingerprint identification unit is usually disposed in the non-display area of ​​the display panel. For the display panel with this structure, when performing authorization verification, the user ...
