Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be fully described below through specific implementation in combination with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts, All fall within the protection scope of the present invention.

[0027] 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.

Abstract

The embodiment of the invention discloses a touch control display panel and a display device. The touch control display panel comprises a substrate, a plurality of fingerprint recognition units, touch control electrodes, and shading stop walls. The fingerprint recognition units respectively comprise a photosensitive diode which comprises a light-sensing surface. The touch control electrodes are respectively located at one side of the light-sensing surface of the corresponding photosensitive diode. The shading stop walls are located between a film layer where the fingerprint recognition units are located and a film layer where the touch control electrodes are located, and the vertical projections of the shading stop walls on the substrate are at least located between the vertical projections of the photosensitive diodes on the substrate and the vertical projections of the touch control electrodes on the substrate. The shading stop walls are used for shading the light reflected by the touch control electrodes to the light-sensing surfaces of the photosensitive diodes. The shading stop walls are used for shading the light reflected by the touch control electrodes to the light-sensing surfaces of the photosensitive diodes, thereby guaranteeing that the touch control electrodes cannot cause the increase of the fingerprint recognition noise, and guaranteeing the fingerprint recognition accuracy.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of semiconductors, and in particular, to a touch display panel and a display device. Background technique [0002] Fingerprints are inherent and unique to everyone. 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 fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] In the fingerprint identification process, the fingerprint identification unit performs fingerprint identification according to the light reflected from the touch subject (such as a finger) to the fingerprint identification unit, but for a di...
