Embodiment Construction

[0049] It can be seen from the background art that, in the prior art, touch panels integrated with biometric identification functions often cannot obtain good integration and imaging effects. refer to figure 1 , shows a schematic cross-sectional structure of a touch panel.

[0050]The touch panel includes: a touch surface 11 for user contact; a touch layer 12 and an optical sensing layer 13 located on one side of the touch surface 11 in sequence. In some embodiments, the touch layer 12 and the optical sensing layer 13 are bonded together. Specifically, the touch layer 12 and the optical sensing layer 13 are bonded by an adhesive 14 .

[0051] The optical sensor layer 13 is pasted on the side of the touch layer 12 facing away from the touch surface 11 through the adhesive 14, thereby affecting the improvement of the integration of the touch panel; and the optical sensor The sensing layer 13 and the touch layer 12 are often pasted through the assembly process after the produc...

Abstract

The invention discloses a touchpad, electronic equipment and a user identity authentication method thereof. The touchpad comprises: a touch surface; and an imaging touch module which is suitable for collecting an image of a user contact part on the touch surface and sensing the contact or action of a user on the touch surface, wherein a light sensing surface of anoptical sensing assembly is back to the touch surface. The imaging touch module not only can sense contact on a touch surface, but also can collect light reflected by the touch surface to carry out imaging, the imaging touch module is integrated in a one-piece mode, and compared with the scheme that an optical sensing assembly and a touch assembly which are separated from each other are assembled in an attaching mode and the like, the touchpad has the advantages that the stability, the integration level and the optical precision of the device can be obviously improved; and the light sensing surface of the optical sensing assembly in the imaging touch module is back to the touch surface, so that the influence of ambient light on the imaging function can be effectively inhibited, the imaging effect is improved, the imaging area is favorably enlarged, and the user experience is favorably improved.

Description

technical field [0001] The invention relates to the field of identification and control, in particular to a touch panel, an electronic device and a user identity authentication method thereof. Background technique [0002] In biometric technology, fingerprint recognition technology collects the fingerprint image of the human body through the image sensor, and then compares it with the existing fingerprint information in the recognition system to realize identity recognition. Due to the convenience of use and the uniqueness of human fingerprints, fingerprint identification technology has been widely used in various fields. [0003] A touchpad (touchpad) is a very common touch device in electronic equipment, and its touch function and fingerprint identification technology have a natural integration advantage. The imaging methods used in fingerprint identification technology include optical, capacitive, ultrasonic and other technologies. One of them is to collect fingerprint ...
