A capacitive touch screen with fingerprint recognition

Abstract

The present invention relates to a capacitive touch screen capable of fingerprint recognition. The capacitive touch screen comprises a first lens, a second lens and a fingerprint recognition chip. The second lens has a touch sensing function. The first lens is attached to an outer side surface of the second lens. An opening or a through hole is provided on the second lens, the opening or the through hole and the first lens define a receiving chamber. The fingerprint recognition chip is disposed in the receiving chamber. The fingerprint recognition chip is disposed in the receiving chamber, the fingerprint recognition chip is hidden at the back of the first lens, and a surface of the first lens keeps flat, so that not only the appearance is better but also the glass strengthened structure is more complete. The capacitive touch screen has higher overall strength and firmness; The second lens is attached to the inner side surface of the first lens, and the second lens not only has the touch sensing function, but also has higher strength. The first lens can be formed thinner so as to reduce the distance between the fingerprint recognition chip and the finger and the distance between a touch sensing circuit layer and the finger, thereby enhancing the fingerprint recognition capability and the touch sensing capability.

Description

technical field The invention relates to a touch screen, in particular to a capacitive touch screen with fingerprint recognition. Background technique With the development of thinner and lighter touch screens, single-chip capacitive touch screens have gradually become the mainstream and are widely used in mobile phones, tablet computers and other electronic products. on the surface, and realize the touch display function. In order to realize the fingerprint identification function, directly integrating the fingerprint identification function chip on the capacitive touch screen can undoubtedly achieve the purpose of simplifying the structure of electronic products such as mobile phones and tablet computers. However, as shown in FIG. 1 , the current general practice is to dig out an accommodating hole 03 capable of accommodating the fingerprint identification chip 02 on the single-chip capacitive touch screen 01, and then nest the fingerprint identification chip 02 in the a...
