Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] As mentioned in the background art, the fingerprint recognition module of the existing touch display device is a separate accessory installed in it, which not only increases the cost of the touch display device, but also occupies a certain space of the touch display device. It is not conducive to the trend of thinner and lighter touch display devices.

[0039] Based on this, the embodiment of the present application provides a touch screen, a display pa...

Abstract

The invention discloses a touch screen with a fingerprint identification function, a display panel and a touch display apparatus. The touch screen comprises a touch function layer, wherein the touch function layer comprises a plurality of first touch electrodes arranged in a first direction and a plurality of second touch electrodes arranged in a second direction; the first touch electrodes and the second touch electrodes are crossly arranged; the touch function layer is also integrated with a fingerprint identification region; the fingerprint identification region comprises a plurality of first fingerprint detection electrodes arranged on the same layer as the first touch electrodes; and the first fingerprint detection electrodes, the first touch electrodes and the second touch electrodes are mutually insulated. By arranging the first fingerprint detection electrodes and the first touch electrodes on the same layer, the fingerprint identification region integrated to the touch function layer is formed and a fingerprint identification module does not need to be manufactured separately, so that the cost of the touch display apparatus is reduced and the lighting and thinning trend of the touch display apparatus is facilitated.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, and more specifically, to a touch screen, a display panel, and a touch display device with a fingerprint identification function. Background technique [0002] In recent years, with the development of electronic technology, touch display devices such as smart phones and tablet computers have become more and more widely used in people's daily life, and the current touch display devices have more and more functions, providing users with Provides more convenience. However, while the touch terminal provides users with more convenience, it also carries a large amount of private information. Once the touch display device is lost, the private information will be leaked. Therefore, the security of the touch display device becomes more as important. [0003] An encryption method of today's touch display devices is to use fingerprint encryption. Since fingerprints are unique characteri...
