Abstract

The invention discloses a touch screen and terminal equipment with a fingerprint identification function. The touch screen comprises a cover plate, a substrate, a touch induction element and a fingerprint identification element, wherein the cover plate comprises a first area and a second area, and the first area and the second area independently comprise a first surface and a second surface; the substrate comprises a third surface and a fourth surface, and the third surface faces the second surface; the touch induction element comprises a touch induction electrode; the touch induction electrode is overlaid in a visible area; the fingerprint identification element comprises a fingerprint identification electrode; the fingerprint identification electrode is overlaid in a fingerprint induction area in the visible area; the touch induction electrode and the fingerprint identification electrode are overlaid in the same layer in the fingerprint induction area to form a first electrode layer;the first electrode layer is arranged between the second surface and the third surface; and a second electrode layer is formed by the touch induction electrode in the visible area and a non-fingerprint induction area, and is arranged on a fourth surface. The touch screen and terminal equipment with the fingerprint identification function are high in fingerprint identification sensitivity, and thearea of a non-visible area can be reduced.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a touch screen with a fingerprint recognition function and a terminal device including the touch screen. Background technique [0002] With the development of storage technology, terminal devices such as smartphones and tablet computers store a large amount of personal information and other important data, and its security becomes more important. At present, passwords, graphics and other forms are often used to realize the password protection of its terminal equipment, but it often needs to increase the complexity of passwords and graphics, which undoubtedly increases the difficulty of user memory and causes conflicts between security and ease of use. [0003] Fingerprints are composed of uneven skin lines on the surface of fingers, which are unique features of the human body, and their complexity can provide sufficient features for identification. Fingerprint reco...
