Abstract

The invention discloses a fingerprint module and display equipment. The fingerprint module comprises a substrate, a plurality of fingerprint recognition construction members, a fingerprint chip and aplurality of metal wires, wherein the substrate is provided with a recognition area used for fingerprint recognition and a non-recognition area positioned on the periphery of the recognition area; thefingerprint recognition construction members are arranged in the recognition area of the substrate; the fingerprint chip is arranged in the non-recognition area of the substrate; and each fingerprintrecognition construction member is electrically connected to the fingerprint chip through the corresponding metal wire. By use of the fingerprint module, through the fingerprint recognition construction members arranged in the recognition area of the substrate and the fingerprint chip arranged in the non-recognition area of the substrate, a fingerprint recognition area is increased, and full-screen fingerprint recognition is realized.

Description

【Technical field】 [0001] The disclosure relates to the field of fingerprint identification, and in particular to a fingerprint module and a display device. 【Background technique】 [0002] Fingerprints are the lines formed by the uneven skin on the pads of human fingers. Since the repetition rate of fingerprints is extremely small, about one in 15 billion, they can be used for identification. The principle of capacitive fingerprint recognition is based on the difference in capacitance induced by the sunken skin and raised skin on the fingertips. By collecting the capacitance difference induced by the finger pressing on the fingerprint reader, the morphology of the fingerprint can be restored, and then fingerprint identification can be performed. . [0003] In the prior art, the fingerprint recognition technology solution of the display device is the frame on the front or back of the display device, such as 10mm 2 In the limited area, add a fingerprint recognition device, th...
