Problems solved by technology

[0004] Ordinary transparent screen protection glass has very little loss of light, so after it is attached to the screen surface, the fingerprint unlocking function under the screen is basically not affected, but this product only reduces the effect of screen breakage, and does not weaken the performance of the screen blue light, so it does not With eye protection function
[0005] The artificial light source is composed of three primary colors of red, green and blue. The higher the energy of the blue light, the higher the brightness of the light. However, the new screen protector product has an absorption effect on the light energy of the 450nm wavelength, so the intensity of the reflected light will decrease, resulting in photoelectric Insufficient light sensitivity received by the sensing receiver directly affects the sensitivity of fingerprint unlocking under the screen

Embodiment 1

[0028] Cleaning after back protection of the glass substrate, performing chemical etching AG treatment, then removing the back protection and cleaning again, performing vacuum evaporation plating, presetting the plating sequence and thickness of the film material and controlling the entire vacuum evaporation by detecting the thickness of the film layer with a crystal oscillator After the electroplating operation is completed, the surface of the glass after coating is coated with yellow light glue for protection. The coating method can be printing, spraying and roller printing, etc., and the film sheet with local mesh treatment in the fingerprint area is cured and pasted. In the deplating solution, after the yellow light process, the hollow part of the fingerprint area is stripped to restore the original transparency, and then the remaining yellow light film is washed off with a solvent and cleaned to obtain a blue light absorbing coating layer with a mesh hollow in the fingerpri...

Embodiment 2

[0031] Clean the glass substrate after back protection, perform chemical etching AG treatment, then remove the back protection and clean it again, and paste pre-screen dot stickers on the fingerprint area of ​​the glass surface to be coated. Then carry out vacuum evaporation electroplating, preset the electroplating sequence and thickness of the film material, and use the crystal oscillator to detect the thickness of the film layer to control the completion of the entire vacuum evaporation electroplating operation, then remove the fingerprint dot stickers, and get another hollow form after cleaning ,Such as figure 2 shown. Finally, the electroplated glass substrate was moved into an oxygen-enriched box, the oxygen flow rate was 2L / min, the oxygen flow time was 8 minutes, and it was aged for 4 hours. The light reflectance on the surface of the new screen protector has been reduced from 8.3% to 0.53%, and the harmful blue light filtering interception rate has reached 43%. The ...

Embodiment 3

[0033] Cleaning after back protection of the glass substrate, performing chemical etching AG treatment, then removing the back protection and cleaning again, performing vacuum evaporation plating, presetting the plating sequence and thickness of the film material and controlling the entire vacuum evaporation by detecting the thickness of the film layer with a crystal oscillator After the electroplating operation is completed, place the coated film face up on the laser engraving machine, and use the laser to carry out dot-like hollowing out of the coating layer in the fingerprint area. After cleaning, a blue light-absorbing coating layer with a mesh hollow in the fingerprint area is obtained, such as image 3 shown. Finally, the electroplated glass substrate was moved into an oxygen-enriched box, the oxygen flow rate was 2L / min, the oxygen flow time was 8 minutes, and it was aged for 4 hours. The light reflectance on the surface of the new screen protection screen has been redu...

Abstract

The invention belongs to the field of portable information terminal screen light hazard prevention and control, and particularly relates to a processing technology of an anti-glare and anti-blue-lightcomposite screen protection screen suitable for fingerprint unlocking under the screen, which comprises the following steps: carrying out chemical etching AG treatment on one side of a glass substrate; performing anti-blue-ray treatment on the other side of the glass substrate through vacuum evaporation electroplating; positioning a fingerprint unlocking area on the side surface of the glass substrate, and performing mesh hollowing processing on the fingerprint unlocking area; and finally, carrying out aging treatment on the electroplated anti-blue-light plating layer. The product produced bythe process can ensure normal use of an under-screen fingerprint unlocking function, and also has a permanent anti-glare function and a blue light filtering function of a screen protection screen.

Description

technical field [0001] The invention belongs to the field of prevention and control of light hazards on portable information terminal screens, and in particular relates to a processing technology for an anti-glare and anti-blue light composite screen protection screen suitable for fingerprint unlocking under the screen. Background technique [0002] With the rapid development of communication technology, in the information age, the frequency of use of electronic products such as smart phones, tablets, electronic paper books, and computers is basically inseparable, so the phenomenon of screen light damage to people's eyes is becoming more and more common. Existing medical research has proved that the trend of rejuvenation and generalization of eye diseases such as cataract and macular degeneration is directly related to the time of modern people's contact with portable electronic products such as mobile phones. A new type of screen protection screen product with permanent ant...
