Problems solved by technology

[0002] Static electricity has a great impact on mobile phones. During the entire life cycle, mobile phones are in an environment full of static electricity. If the anti-static discharge (ESD) design is not good, it may cause the following phenomena during use: 1) Normal use can be resumed after user intervention: the call is suddenly interrupted; the display screen is blurred, no display, the screen cannot be refreshed (dead screen), black screen; system confusion (garbled characters appear on the screen, the display is inverted); system lock (all key functions fail); Poor quality (deteriorated sound, loud noise); automatic restart or automatic shutdown; additional function failure or performance degradation (such as: camera function, built-in game, song player, web browser, etc.); crash (all functions fail, restart It will return to normal after unplugging the battery)
[0003] 2) Cannot be used normally after user intervention: components may be damaged, and a mobile phone or a certain function of the mobile phone cannot be used (such as confusion of key numbers, key failure, failure to boot, no display, no sound after boot, etc.)
However, when the above method is adopted, specific process processing is required for the screen of the mobile phone, which is time-consuming and labor-intensive, and increases the manufacturing cost of the mobile phone.

Embodiment 1

[0019] Preparation of mixed primer: SiO 2 The powder and ITO powder are mixed at a ratio of 90:10 (the ratio of indium oxide and tin oxide in ITO is 90:10). After mixing evenly, they are sequentially processed through briquetting, cold isostatic pressing, degreasing, sintering, and grinding. Obtain 1# priming drug target material. On the UNIVAC, 1350 type vacuum coating machine, the primer agent is evaporated on the cleaned and activated glass, and the coating condition is a vacuum degree of 5×10 -3 Pa, the electron gun current is 5mA, and the film thickness is 13nm. After the evaporation of the primer agent is completed, the evaporation particles containing 60 mg of the UD509 anti-fingerprint agent of Daikin Company of Japan are placed in a molybdenum boat for AF film evaporation. The coating condition is a vacuum degree of 5×10 -3 Pa, anti-vapor current 750A, film thickness 11.8nm, obtained anti-fouling touch screen glass with anti-static function, and tested the transmitt...

On the UNIVAC, 1350 type vacuum coating machine, the primer agent is evaporated on the cleaned and activated glass, and the coating condition is a vacuum degree of 5×10 -3 Pa, the electron gun current is 5mA, and the film thickness is 15nm. After the evaporation of the primer agent is completed, the evaporation particles containing 60 mg of the UD509 anti-fingerprint agent of Daikin Company of Japan are placed in a molybdenum boat for AF film evaporation. The coating condition is a vacuum degree of 5×10 -3 Pa, anti-vapor current 750A, film thickness 12.8nm, obtained anti-fouling touch screen glass with anti-static function.

Embodiment 3

[0023] Preparation of mixed primer: SiO 2 The powder and ITO powder are mixed at a ratio of 75:25 (the ratio of indium oxide and tin oxide in ITO is 90:10). After mixing evenly, they are successively processed by briquetting, cold isostatic pressing, degreasing, sintering, and grinding. Obtain 3# priming drug target material. On the UNIVAC, 1350 type vacuum coating machine, the primer agent is evaporated on the cleaned and activated glass, and the coating condition is a vacuum degree of 5×10 -3 Pa, the electron gun current is 5mA, and the film thickness is 14nm. After the evaporation of the primer agent is completed, the evaporation particles containing 60 mg of the UD509 anti-fingerprint agent of Daikin Company of Japan are placed in a molybdenum boat for AF film evaporation. The coating condition is a vacuum degree of 5×10 -3 Pa, anti-vapor current 750A, film thickness 12.0nm, obtained anti-fouling touch screen glass with anti-static function, and tested the transmittance,...

Abstract

The invention discloses a preparation method of a touch screen glass with anti-electrostatic and anti-fouling functions. The preparation method comprises the following steps: mixing indium tin oxide (ITO) with silicon dioxide in a certain ratio, preparing a substrate medicinal target, forming a composite coating with ITO and silicon oxide on a touch screen in an evaporation plating manner firstly, and further performing evaporation plating on a fluorosilicone compound coating, thereby obtaining the touch screen with the anti-electrostatic and anti-fouling functions. Due to addition of the ITO, effects of an anti-fouling membrane layer are not affected, that is, the hydrophobicity and the oleophobicity as well as friction resistance are not changed. The invention further discloses the preparation method of the touch screen glass.
