Problems solved by technology

However, the anti-fingerprint film has no anti-scratch function, so once the anti-fingerprint coating is scratched off, the touch screen is easy to be scratched during use, especially for mobile phones and touch screen computers. Many users buy their own film to prevent the screen from being scratched. Injury, but the film is also easy to scratch, so it needs to be replaced constantly

specific Embodiment approach 1

[0022] Specific Embodiment 1: In this embodiment, a scratch-resistant and fingerprint-resistant touch screen includes a top panel, an optical adhesive, and a bottom SENSOR. Adhesive surface top panel and bottom SENSOR, the bottom SENSOR is used for routing lines; the top panel is covered with a vacuum sputtered silicon dioxide film, and the vacuum sputtered silicon dioxide film is covered with a vacuum sputtered silicon dioxide film A diamond-like film; the vacuum-sputtered diamond-like film is covered with a vacuum-evaporated silicon dioxide film; the vacuum-evaporated silicon dioxide film is covered with a vacuum-evaporated anti-fingerprint film.

specific Embodiment approach 2

[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the top panel is a PET panel. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0024] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the bottom SENSOR is a wire circuit board made of PET or GLASS substrate. Others are the same as those in the first or second embodiment.

Abstract

The invention relates to the technical field of semiconductor materials, in particular to a touch screen resistant to scratch and fingerprints and a manufacturing method thereof. The technical problem that fingerprints remain on a touch screen of a mobile phone easily is solved. The touch screen is composed of a top panel, optical cement and bottom SENSOR. The manufacturing method includes the steps of 1 cleaning the top panel; 2 depositing a silicon dioxide film; 3 depositing a quasi-diamond film; 4 depositing a silicon dioxide film through a vacuum evaporation method; 5 depositing a fingerprint-resistant film through a vacuum evaporation method. The top panel is a face cover of the touch screen and is used as a contact face for point contact of a user, the top panel and the bottom SENSOR are glued through the optical cement, and the bottom SENSOR is used for arranging circuits. The manufacturing method of the touch screen resistant to scratch and fingerprints is simple in preparation process, and the touch screen high in scratch resistance can be manufactured.

Description

technical field [0001] The invention relates to the technical field of semiconductor materials, in particular to a scratch-resistant and fingerprint-resistant touch screen and a preparation method thereof. Background technique [0002] At present, all projected capacitive touch screen panels on the market are of GLASS structure. The projected capacitive touch screen structure is composed of top GLASS panel + optical glue + bottom SENSOR (SENSOR material can be ITO FILM or ITO GLASS). [0003] Since the structure of the existing touch screen panel is generally a substrate (such as glass, PMMA, etc.) coated with an anti-fingerprint coating, the touch screen has an anti-fingerprint function, and the anti-fingerprint coating makes the touch screen smoother, easier to slide and less likely to leave fingerprints . However, the anti-fingerprint film has no anti-scratch function, so once the anti-fingerprint coating is scratched off, the touch screen is easy to be scratched during ...
