Problems solved by technology

Since the panel needs to be drilled through holes, the structural strength around the through hole will be affected for the glass panel, and the appearance of the plastic panel will also be affected; moreover, there are through holes on the panel, and sweat, small debris, etc. are easy to pass through. Penetration of holes can affect the reliability of fingerprint recognition devices
In addition, in the prior art, the fingerprint identification device is also a part of the overall appearance of the product, and its color and external dimensions are limited

Embodiment Construction

[0015] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] Such as Figure 1 to Figure 3 As shown, the present invention provides a fingerprint identification touch screen, including a panel 1 and a fingerprint identification device 2 .

[0017] A groove 3 is also provided on the back of the panel 1, and the groove 3 may be a sunken groove formed by cutting or etching. Generally, the panel 1 can adopt a traditional protective substrate made of glass or plastic. In some specific embodiments, the back of the panel 1 can further be provided with a functional sheet 4, such as a conductive film layer and a sensor for realizing the touch function, thereby forming the main body of the OGS touch screen, and the fingerprint identification devic...

Abstract

The invention relates to a fingerprint-recognition touch screen which comprises a panel. A groove is formed on the back of the panel, a fingerprint recognition device is arranged in the groove and comprises an electroconductive ink layer arranged at the surrounding edge in the groove to be annular, and a fingerprint recognition chip arranged in an area surrounded by the electroconductive ink layer, a contact of the fingerprint recognition chip contacts with the electroconductive ink layer, and the fingerprint recognition chip is connected to a main control chip of the touch screen through a lead. The fingerprint recognition device is arranged in the groove in the back of the panel, and no through hole needs to be punched in the panel, so that complete appearance of the panel can be maintained. The fingerprint recognition device is arranged on the back of the panel, thereby being needless of direct contact with a human body and less prone to being damaged due to being dipped by sweat and water; size of a fingerprint recognition sensing and controlling portion on the back of the panel is not limited.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a fingerprint identification touch screen. Background technique [0002] In the existing touch screen with fingerprint identification, the fingerprint sensor and the control chip are enclosed in a metal ring, a through hole is punched in the panel of the touch screen, and the fingerprint identification device is fixed in the through hole. Since the panel needs to be drilled through holes, the structural strength around the through hole will be affected for the glass panel, and the appearance of the plastic panel will also be affected; moreover, there are through holes on the panel, and sweat, small debris, etc. The penetration of the hole will affect the reliability of the fingerprint identification device. In addition, in the prior art, the fingerprint identification device is also a part of the overall appearance of the product, and its color and external dimensions are ...
