Problems solved by technology

Among them, COP, PC, and TAC solve light interference and light polarization, but these materials themselves have irreparable defects: COP is amorphous, and PC is a linear molecule, so there is no light orientation, low phase difference, and perfect Avoid the problem of decreased sensitivity of fingerprint recognition caused by light interference and polarization
[0007] Therefore, COP, PC, TAC, SRF and ordinary PET cannot be used alone as a finished product of mobile phone protective film

Embodiment Construction

[0033] Please refer to Figure 1 to Figure 3 Shown, it has shown the specific structure and method of preferred embodiment of the present invention, is a kind of fingerprint unlocking mobile phone protective light-cured film manufacturing method, comprises the following steps:

[0034] In the first step, take a modified transparent PC tape 1 with a phase difference <20, and roll it into a PC roll. In this embodiment, the refractive index of the modified transparent PC tape 1 is 1.585, the light transmittance is 95%, the impact resistance value is 140 j / m, the Rockwell hardness is 77 M scale, the flexural modulus is 2230 Mpa, and the tensile The yield point is 61 Mpa, the tensile breaking point is 140 Mpa, and the phase difference is 12. This kind of modified transparent PC tape 1 can be processed and manufactured by purchasing the existing Japanese Teijin modified PC material on the market. The inventor melts the purchased Japanese Teijin modified PC material, and then modif...

Abstract

The invention discloses a method for manufacturing a protective photocuring film of a fingerprint unlocked mobile phone. The method comprises the following steps: 1, rolling a modified transparent PCbelt having a phase difference of less than 20 into a PC roll; 2, printing photocuring reflection ink to the surface of the PC roll; 3, rolling a transparent SRF belt having a phase difference of morethan 8000 into an SRF roll; 4, pulling the PC roll in the step 2 and the SRF roll in the step 3 with the same machine, and respectively coating solvent-free OCA optical colloid and hardening UV glueto faces to be adhered between the PC roll and the SRF roll, and compounding through photocuring, wherein the solvent-free OCA optical colloid has a refractive index of 1.608, and the hardening UV glue has a refractive index of 1.478; and 5, adhering two layers by a mode of adhering opposite sides in the same direction of the same roll. The protective photocuring film of a fingerprint unlocked mobile phone prepared by the method can combine advantages of PC and SRF optical materials, and is applicable to under-screen fingerprint unlocking.

Description

technical field [0001] The invention relates to the technology in the field of mobile phone protective films, in particular to a method for manufacturing a protective light-cured film for unlocking mobile phones with fingerprints. Background technique [0002] The fingerprint unlocking recognition is completed under the screen glass, mainly using infrared or optical technology to achieve fingerprint recognition through different materials. Light is a kind of transverse wave, and its propagation direction is consistent with the vibration direction. The factors affecting the transmittance are as follows: [0003] 1. Interference of light: When N light waves meet in space, they superimpose each other, always strengthen in some areas, and always weaken in other areas, which will cause a stable intensity distribution phenomenon. [0004] 2. Light polarization: the phenomenon that the spatial distribution of light wave electric vector vibration loses symmetry with respect to the ...
