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] In any embodiment of the present invention, the display panel includes a fingerprint identification light source. In actual setting, the light emitting unit in the display panel can be reused as a fingerprint recognition light source, or an external light source can be used as a fingerprint recognition light source. This application is not limited to this. For ease of understanding, in each figure, the formation and propagation path of fingerprint signal light are drawn by taking the multiplexing of the li...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a base substrate including a plurality of opening regions and non-opening regions surroundingthe opening regions, a pixel defining layer formed on the base substrate, a thin film packaging layer formed on a side of the pixel defining layer away from the base substrate, and a fingerprint signal acquisition module which is at any of the following positions including a position between the pixel defining layer and the thin film packaging layer, a position at one side of the thin film packaging layer away from the pixel defining layer and a position in the thin film packaging layer, wherein the vertical projection of the pixel defining layer on the base substrate is in the non-opening regions. According to the display panel provided by the embodiment of the invention, the fingerprint recognition accuracy of the display panel can be improved.

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...
