Abstract

The invention provides a fingerprint sensing device and electronic equipment. The fingerprint sensing device comprises a panel assembly and a fingerprint identification module arranged below the panel assembly, wherein the fingerprint identification module comprises a flexible element and a fingerprint identification circuit arranged above the flexible element; a switch module is embedded into the flexible element and comprises a supporting piece which is in contact with the upper top of the flexible element and a non-conductive elastic element positioned below the supporting piece; conductive bosses are formed in the supporting piece and the non-conductive elastic element and are in contact with a welding disk circuit at the lower bottom of the flexible element when the fingerprint sensing device is pressed; by starting of the switch module, the flexible element is conducted, and electric coupling is formed between the flexible element and the fingerprint identification circuit. According to the fingerprint sensing device disclosed by the embodiment of the invention, the problem of higher abrasion to the fingerprint sensing device due to deformation caused by pressing in the prior art when the fingerprint sensing device generates an electric signal due to pressing of a finger of a user is solved.

Description

technical field [0001] The invention relates to fingerprint identification technology, in particular to a fingerprint sensing device and electronic equipment. Background technique [0002] With the continuous development of electronic technology and semiconductor technology, users have higher and higher requirements for the safety of electronic equipment. Fingerprints are a unique feature of the human body. Fingerprint recognition technology using fingerprint features as verification codes has been widely used in the security of electronic equipment. Verifying. [0003] Fingerprint recognition is to use the characteristics of uniqueness and stability of fingerprints to realize user identification, and it does not require users to memorize verification codes. Therefore, the application of fingerprint recognition technology is becoming more and more popular. Common fingerprint sensing devices include, for example, a capacitive fingerprint sensor. The capacitive fingerprint se...
