Embodiment Construction

[0033] As mentioned in the background, existing optical sensor modules have poor performance.

[0034] An optical sensor module, reference figure 1 , comprising: a self-luminous display panel 100; an optical sensor 110; a light collimation layer 120 between the self-luminous display panel 100 and the optical sensor 110; a light collimation layer between the light collimation layer 120 and the optical sensor 110 120 and the adhesive layer 130 between the self-luminous display panel 100 .

[0035] The material of the adhesive layer 130 is optical glue.

[0036] The adhesive layer 130 bonds the self-luminous display panel 100 and the light-collimating layer 120, and bonds the optical sensor 110 and the light-collimating layer 120, avoiding an air layer between the self-luminous display panel 100 and the optical sensor 110, The light scattering phenomenon caused by the air layer is avoided, thereby improving the clarity of the image of the optical sensor.

[0037] After bonding...

Abstract

The invention discloses an optical adhesive material and an optical sensor module. The optical sensor module comprises a self-luminous display panel; an optical sensor; the optical bonding layer whichis located between the optical sensor and the self-luminous display panel, stress dispersion particles are arranged in the optical bonding layer, and the stress dispersion particles are pervious to light. The performance of the optical sensor module is improved.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to an optical adhesive and an optical 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, 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 imaging and other technol...
