Embodiment Construction

[0041] It can be seen from the background art that the key structure with fingerprint identification function in the prior art often has the problem of too low strength. Now combine a key structure with fingerprint recognition function to analyze the reason of its weak strength:

[0042] refer to figure 1 , showing a key structure with fingerprint recognition function.

[0043] The button structure includes: a keycap 11, the keycap 11 has a top plate 12, the top plate 12 has a pressing surface 12a and a bottom surface 12b arranged opposite to each other, and the pressing surface 12a is used to accept touch and press; a fingerprint recognition module 13 , the fingerprint recognition module 13 is pasted on the bottom surface 12 a of the top board 12 .

[0044] The fingerprint recognition module 13 is usually a capacitive fingerprint recognition chip, which obtains a fingerprint image for identity recognition by collecting a capacitive signal carrying fingerprint information. T...

Abstract

The invention relates to a key structure and electronic equipment. The key structure comprises a key cap and an optical fingerprint identification module, wherein the key cap is provided with a top plate, and the top plate comprises a pressing surface and a bottom surface which are oppositely arranged; and the optical fingerprint identification module is located on one side of the top plate, the optical fingerprint identification module comprises an image sensor, and the image sensor is attached to the bottom surface of the top plate. Through the adoption of the optical fingerprint identification module, the increase of the thickness of the top plate becomes possible, so that the strength of the key structure can be effectively improved, and the key structure is better compatible with a pressing function and a fingerprint identification function.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a button structure and electronic equipment. Background technique [0002] The fingerprint identification technology collects the fingerprint image of the human body through the fingerprint imaging module, and then compares it with the existing fingerprint imaging information in the fingerprint identification system to realize identity identification. Due to the convenience of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as: public security bureaus, customs and other security inspection fields, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] The imaging methods of the fingerprint recognition module used in the fingerprint recognition technology include optical, capacitive, ultrasonic and other methods. Among them, one is to ...
