Embodiment Construction

[0044] 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.

[0045] 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 ...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a display module, a fingerprint recognition module, and at least one layer of black matrix, wherein the display module comprises a first substrate and multiple pixel circuits, the first substrate comprises a display region and a non-display region around the display region; multiple pixel circuits are located inside the display region of the first substrate, each pixel circuit comprises multiple thin film transistors, each thin film transistor comprises a grid electrode, a source electrode and a drain electrode; the fingerprint recognition module is formed inside the display region at one side, facing away from the thin film transistor, of the first substrate; the at least one layer of black matrix is arranged between the thin film transistor and the fingerprint recognition module, the black matrix comprises shading areas and an opening area located between the shading areas; the projections of the grid electrode, the source electrode and the drain electrode of the thin film transistor are located inside the projection of the shielding area on the first substrate. An aim of improving the fingerprint recognition precision of the display panel can be achieved by use of the embodiment of the invention.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they are unique. 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. In this way, before operating the display device with fingerprint identification function, the user only needs to touch the fingerprint sensor of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, if the fingerprint sensor is directly arranged in the display area of ​​the display panel, since the gate, source and drain of the thin film transistor in the pixel circuit in the display area of...
