Embodiment Construction

[0029] As mentioned in the background, the performance of the optical fingerprint sensor module formed by the prior art is relatively poor.

[0030] An optical fingerprint sensor module, please refer to figure 1 , comprising: an optical fingerprint sensor 110 ; a self-luminous display panel 120 ; a light collimator panel 130 located between the optical fingerprint sensor 110 and the self-luminous display panel 120 .

[0031] Usually, the optical fingerprint sensor 110 and the light collimator panel 130 are bonded by the first adhesive glue 140 , and the self-luminous display panel 120 and the light collimator panel 130 are bonded by the second adhesive glue 150 .

[0032] The materials of the first adhesive glue 140 and the second adhesive glue 150 can be selected from materials that need to be heated and bonded, and the materials of the first adhesive glue 140 and the second adhesive glue 150 can also be selected from materials that do not need to be heated and bonded, that i...

Abstract

The invention relates to an optical fingerprint sensor module and a forming method thereof, the method comprises the following steps: providing an optical fingerprint sensor, a self-luminous display panel and an optical collimator panel, the optical collimator panel having a first bonding surface and a second bonding surface opposite to each other; providing a first initial ultraviolet curing adhesive and a second initial ultraviolet curing adhesive; after the optical fingerprint sensor and the first bonding surface of the optical collimator panel are bonded together through a first initial ultraviolet light curing adhesive, performing first ultraviolet light curing on the first initial ultraviolet light curing adhesive to enable the first initial ultraviolet light curing adhesive to forma first ultraviolet light curing adhesive; and after the second bonding surfaces of the self-luminous display panel and the optical collimator panel are bonded together through a second initial ultraviolet light curing adhesive, performing second ultraviolet light curing on the second initial ultraviolet light curing adhesive to enable the second initial ultraviolet light curing adhesive to form asecond ultraviolet light curing adhesive. According to the method, the performance of the optical fingerprint sensor module is improved.

Description

technical field [0001] The invention relates to the field of optical fingerprint identification, in particular to an optical fingerprint sensor module and a forming method thereof. 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, such as security inspection fields such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones. [0003] The imaging methods of fingerprint imaging recognition technology include optical imaging, capacitive imaging, ultrasonic i...
