Problems solved by technology

Generally speaking, the fingerprint identification area is set in the non-visible area. However, due to the trend of mobile devices gradually developing towards narrow borders, the size of the non-visible area is getting smaller and smaller. Therefore, how to set the fingerprint identification area in the mobile device is one of the important topics in related fields

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 A top view of a touch device according to an embodiment of the present invention is shown. figure 2 draw figure 1 The touch device along figure 1 Sectional drawing of line 2-2. Such as figure 1 and 2 As shown, the touch device may include a cover plate 100 , a fingerprint sensing layer 200 and a light shielding layer 300 . The cover plate 100 has an inner surface 101 and an outer surface 102 opposite to each other. The outer surface 102 can be a user touch operation surface. In some embodiments, functional layers such as anti-smudge, anti-fingerprint, anti-scratch or anti-glare can be provided on the outer surface 102 . In some embodiments, the material of the cover plate 100 can be a transparent material, such as glass, but the invention is not limited thereto. The outer surface 102 and the inner surface 101...

Abstract

The invention provides a fingerprint identification device which comprises a cover plate, a plurality of first fingerprint induction electrodes, a plurality of second fingerprint induction electrodes and one or more capacitance compensation structures, wherein the cover plate is provided with a visible region; the plurality of first fingerprint induction electrodes and the plurality of second fingerprint induction electrodes are arrayed in the visible region in a staggered manner; the plurality of first fingerprint induction electrodes are insulated from the plurality of second fingerprint induction electrodes; each first capacitance compensation structure is arranged above one of the plurality of first fingerprint induction electrodes; the light transmittance rate of the first capacitance compensation structure is greater than that of the corresponding first fingerprint induction electrode. According to the fingerprint identification device, the fingerprint induction electrodes are arranged in the visible region, and the fingerprint induction electrodes in the visible region are endowed with sufficient invisibility and sensitivity.

Description

technical field [0001] The invention relates to a fingerprint identification device. Background technique [0002] In current mobile devices, touch panels are quite popular input devices. In order to improve the confidentiality of user data, many mobile devices use specific authentication mechanisms to authenticate users. A typical authentication mechanism requires the user to enter a password. If the entered password is correct, the mobile device allows the user to perform further operations. However, such a password verification mechanism requires the user to input each character of the password one by one, so it is not convenient for the user to operate. Therefore, some mobile devices use biometric identification such as fingerprints, faces, or irises to authenticate users. [0003] Taking fingerprint identification as an example, the mobile device may include a fingerprint identification area. In the fingerprint identification area, a plurality of electrode lines can...
