Embodiment Construction

[0025] 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 here 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, only some structures related to the present invention are shown in the drawings but not all structures.

[0026] figure 1 It is a structural schematic diagram of an existing display panel. see figure 1 , the display panel includes a base substrate 010 , a planarization layer 011 formed on the base substrate 010 , a light emitting unit 021 formed on the planarization layer 011 and a fingerprint signal collection module 022 . Because in actual image display, the light L01 emitted by the light emitting unit 021 along the direction parallel to the light emitting surface of the display panel will directly irradiate the f...

Abstract

The embodiment of the present invention discloses a display panel and a display device. The display panel includes: a base substrate; a control circuit layer formed on the base substrate, and the control circuit layer includes a plurality of pixel circuits arranged at intervals and a plurality of fingerprint identification circuit; a planarization layer formed on the control circuit layer; a plurality of fingerprint signal acquisition modules formed between the control circuit layer and the planarization layer, and the fingerprint signal acquisition module is electrically connected to the corresponding fingerprint identification circuit; formed on the planarization layer There are a plurality of light emitting units on the top, and the light emitting units are electrically connected with corresponding pixel circuits. The display panel provided by the embodiment of the present invention solves the problem that in the existing display panel, since the light emitted by the light-emitting unit directly irradiates the fingerprint signal acquisition module, the base signal of at least part of the fingerprint signal acquisition module increases, which affects the actual fingerprint signal light. The detection of the display panel leads to the problem of low fingerprint identification accuracy of the display panel, and achieves the effect of improving the fingerprint identification accuracy of the display panel.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a display device with a fingerprint recognition function. Background technique [0002] Each person's skin texture, including fingerprints, varies in patterns, breakpoints, and intersections, which are unique and remain unchanged throughout life. Accordingly, we can match a person with his fingerprint, and verify his real identity by comparing his fingerprint with the pre-saved fingerprint data. This is fingerprint recognition technology. Thanks to electronic integrated manufacturing technology and fast and reliable algorithm research, optical fingerprint recognition technology in fingerprint recognition technology has begun to enter our daily life, and has become the most in-depth research, the most widely used and the most mature in biometrics. technology. [0003] At present, the optical fingerprint identification technology...
