Problems solved by technology

[0002] The fingerprint identification method provided by the existing technology will cause difficulty in image acquisition when there is sweat on the finger or other stains on the finger, which will affect the imaging effect of the fingerprint. The loss in the process of transmitting fingerprint information is large, resulting in possible distortion of information extraction. The accuracy of recognition is low

Abstract

The invention discloses a display panel, a display device and a manufacturing method of the display panel, comprising: a display area, the display area includes a plurality of pixels and a plurality of transparent parts, and the plurality of pixels and the plurality of transparent parts are arranged in an array; an array substrate It includes: a first substrate; a plurality of gate lines, a plurality of photoelectric sensors, a color filter substrate including a plurality of color resistors, and in the display area, the color resistors are set corresponding to the pixels; the display panel includes at least an unlocked state and a display state, and the In the unlocked state, the transparent part is in a transparent state, and the light emitted from the transparent part is reflected by the finger to form reflected light that is incident on the photoelectric sensor for fingerprint identification; in the display state, the transparent part is in a black state. By setting the transparent part, the fingerprint identification in the display area is realized, and the accuracy rate of fingerprint identification is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel, a display device and a method for manufacturing the display panel. Background technique [0002] The fingerprint identification method provided by the existing technology will cause difficulty in image acquisition when there is sweat on the finger or other stains on the finger, which will affect the imaging effect of the fingerprint. The loss in the process of transmitting fingerprint information is large, resulting in possible distortion of information extraction. The recognition accuracy is low. Contents of the invention [0003] In view of this, the present invention provides a display panel, comprising: an array substrate and a color filter substrate arranged oppositely, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate; a display area, the display area includes a plurality of pixels and a pl...
