A fingerprint identification apparatus and an electronic apparatus having the fingerprint identification apparatus

Abstract

The invention relates to a fingerprint identification apparatus with a concealed protection member and an electronic apparatus with the fingerprint identification apparatus. The fingerprint identification apparatus comprises a button, a fingerprint sensor which is arranged in a lower portion in the design direction of a button vertical lamination structure, a cover comprising a button hole accommodating the button and a fingerprint sensor positioned below the button and a protection member arranged on below the cover plate or on the side walls of the button hole. The protection member is arranged below the upper surface of the cover plate in a hidden mode. The protection member circes around the surrounding of the fingerprint sensor in order to shield interferences to the fingerprint sensor by outside noise signals. The electronic apparatus with the above fingerprint identification apparatus comprises a housing and a display assembly. The cover plate is embedded in an upper plate of the housing. The display assembly is a display module group or a touch control display module group. The fingerprint sensor is positioned outside of an imaging area of the display assembly.

Description

【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification device with a hidden protective part and electronic equipment with the fingerprint identification device. 【Background technique】 [0002] Fingerprint sensing technology has been widely used and is often used to provide secure access to sensitive electronic devices and / or sensitive data. In general, a capacitive fingerprint recognition module can be used to determine a fingerprint image by measuring the capacitance across a plurality of capacitive sensing elements. [0003] The capacitive fingerprint recognition device used in electronic equipment is often combined with the button of the electronic device, and the button is a position that users often touch, so installing a capacitive fingerprint recognition device here is most in line with the user's usage habits and will also It is relatively easy and convenient to collect the u...

Problems solved by technology

[0005] The protective part in this example is a specially manufactured component, and there are often the following problems that are difficult to overcome: (1) When the protective part is assembled with the keypad, the periphery of the electronic device, and the capacitive sensing array, it is difficult to grasp the tolerance and fit due to size problems. Reduce the assembly precision of the equipment; (2) The position of the protective part is relatively special, and it needs to be placed close to the key, and the protective part is exposed around the key. Because the surface of the finger is protruding, the highest surface of the key is lower than the highest surface of the cover plate of the electronic device. The surface can form a recessed structure to accommodate fingers, so that the protection around the key should be flush with the cover of the electronic device, and higher than the height of the key and the fingerprint recognition module under the key, and finally the protection will be exposed on the Around the key, it is very unsightly; (3) when the protective part is exposed around the key, the residual dirt and oil stains on the fingers are more likely to enter the gap between the protective part and the fingerprint identification device or electronic equipment, which not only affects the aesthetics, It will also indirectly reduce the sensitivity of the induction, and cause oxidative corrosion or damage to the protective parts; (4) The production of the protective parts needs to be molded separately, and the use of purchased protective parts to assemble electronic equipment with fingerprint recognition devices will increase the Product cost is not conducive to the promotion and use of fingerprint recognition functions in electronic devices

[0006] To sum up the disadvantages mentioned above (i.e. the problem of assembling tolerances, the problem of exposure and damage of protective parts, and the corresponding cost problems caused by previous disclosures), a better fingerprint identification device and electronic equipment with the fingerprint identification device are as follows: desired
