Embodiment Construction

[0029] An existing optical fingerprint sensor module such as figure 1 As shown, it includes structures such as a protective layer 110 , an optical fingerprint sensor (not marked), a light guide plate 122 , and a light source 124 . The optical fingerprint sensor includes a pixel substrate 121 and a flexible printed circuit board (not labeled). The pixel substrate has a pixel array ( figure 1 not shown). The flexible printed circuit board includes three parts, the first part 1251 is bound on the upper surface of the pixel substrate (the first part 1251 of the flexible printed circuit board refers to the part of the flexible printed circuit board higher than the pixel substrate 121), the second The third part 1253 is located at the bottom of the optical fingerprint sensor, and the second part 1252 connects the first part 1251 and the third part 1253 .

[0030] The protective layer 110 has an outer surface and an inner surface. Among them, the outer surface is figure 1 In the...

Abstract

The invention discloses an optical fingerprint sensor module, comprising an optical fingerprint sensor, a protection layer located above the optical fingerprint sensor, and a heightening layer located between the protection layer and the optical fingerprint sensor, wherein the optical fingerprint sensor is provided with a light transmitting base plate and a device layer located on the surface of the light transmitting base plate, the device layer is provided with a pixel zone, the pixel zone is provided with multiple pixels, each pixel is provided with a light transmitting area and a lightproof area, each lightproof area is provided with a photosensitive element, each light transmitting area enables light rays to penetrate through the pixel zone, and the optical fingerprint sensor is provided with a binding zone; the heightening layer at least covers the pixel zone. The optical fingerprint sensor module is simplified in structure and improved in reliability.

Description

technical field [0001] The invention relates to the field of optical fingerprint identification, in particular to an optical fingerprint sensor module. Background technique [0002] Fingerprint imaging recognition technology is to collect the fingerprint image of the human body through the optical fingerprint sensor, and then compare it with the existing fingerprint imaging information in the system to judge whether it is correct or not, and then realize the technology of identity recognition. Due to its ease of use and the uniqueness of human fingerprints, fingerprint imaging recognition technology has been widely used in various fields. For example, security inspection areas such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones, etc. The realization of fingerprint imaging recognition technology includes optical imaging, capacitive imaging, ultrasonic imaging and other technologies. ...
