Problems solved by technology

[0006] The current mobile phone touch screen will have the following problems during the preparation process: 1. The prepared mobile phone touch screen is not suitable for high temperature environments; 2. The operation of the mobile phone touch screen depends on the contact between the finger and the screen, and can only recognize limited types of gestures, such as Touching and sliding, etc., limit the diversity of human hand movements; 3. The touch screen of the mobile phone does not have the function of confidentiality after preparation, and the screen may be spied on in public places, or information leakage may occur after the mobile phone is stolen

specific Embodiment 1

[0038] like Figure 1-4 As shown, a method for preparing a touch screen of a mobile phone with a high temperature resistance and an ultra-narrow frame includes a touch screen body 1 and an organic substrate 3. The preparation process of the touch screen body 1 is as follows:

[0039] Sp1: The PET substrate 4 is arranged on the surface of the organic substrate 3, and the organic substrate 3 and the PET substrate 4 are stacked and mounted, and both sides of the organic substrate 3 and the PET substrate 4 are cut and processed, and the organic substrate 3 and the PET substrate 4 are cut and processed. Cut planes are formed on both sides, the organic substrate 3 includes graphene, a single layer of graphene is prepared on copper foil by chemical vapor deposition, and then a layer of polymethyl methacrylate is coated on the surface of the graphene, and the copper foil is etched to form Organic substrate 3.

[0040] Sp2: Coat the second ITO layer 10 on the surface of the cut surfac...

specific Embodiment 2

[0053] The difference from the first embodiment is that the PET substrate 4 is replaced with other transparent substrates of polymer materials.

[0054] like Figure 1-4 As shown, a method for preparing a touch screen of a mobile phone with a high temperature resistance and an ultra-narrow frame includes a touch screen body 1 and an organic substrate 3. The preparation process of the touch screen body 1 is as follows:

[0055] Sp1: Set other transparent substrates of polymer materials on the surface of the organic substrate 3, such as plexiglass, acrylic substrates, etc., and install the organic substrate 3 and the transparent polymer material substrates in an overlapping manner, and install the organic substrate 3 and the transparent polymer material substrates. The two sides of the organic substrate 3 and the two sides of the transparent substrate of polymer material are cut to form cut surfaces;

[0056] Sp2: Coat the second ITO layer 10 on the surface of the cut surface i...

specific Embodiment 3

[0062] The difference from the specific embodiment 1 is that different PVD coating gases are used, the color tone of the touch screen can be adjusted, and the mobile phone touch screen used by different groups of people can be prepared.

[0063] like Figure 1-4 As shown, a method for preparing a touch screen of a mobile phone with a high temperature resistance and an ultra-narrow frame includes a touch screen body 1 and an organic substrate 3. The preparation process of the touch screen body 1 is as follows:

[0064] Sp1: Set the PET substrate 4 on the surface of the organic substrate 3, and install the organic substrate 3 and the PET substrate 4 in an overlapping manner, and cut both sides of the organic substrate 3 and the PET substrate 4. Cut planes on both sides;

[0065] Sp2: Coat the second ITO layer 10 on the surface of the cut surface in step Sp1, and install the connecting frame 2, the connecting frame 2 is attached to the cut surfaces of the organic substrate 3 and...

Abstract

The invention provides a preparation method of a high-temperature-resistant ultra-narrow-frame mobile phone touch screen, and relates to the technical field of mobile phone touch screens, a touch screen body and an organic substrate are included, and the preparation process of the touch screen body is as follows: Sp1, a PET substrate is arranged on the surface of the organic substrate, and the organic substrate and the PET substrate are mounted in an overlapped mode; carrying out cutting processing treatment on two sides of the organic substrate and the PET substrate; sp2, coating a second ITO (Indium Tin Oxide) layer on the surface of the tangent plane in the step Sp1; sp3, preparing a first ITO (Indium Tin Oxide) layer; sp4, a SiO2 protective layer is prepared; sp5, a high-temperature-resistant layer is prepared, and the surface of the SiO2 protective layer is coated with a high-temperature-resistant pressure-sensitive adhesive; sp6, preparing a secrecy layer; and Sp7, printing electronic circuits on the surfaces of the first ITO layer and the second ITO layer. The problem that the touch screen body cannot be suitable for a high-temperature environment is solved; the problems that a touch screen body can only recognize limited types of gestures such as touch and sliding, the diversity of hand actions of a human body is limited, and the touch screen body does not have confidentiality are solved.

Description

technical field [0001] The invention relates to the technical field of mobile phone touch screens, in particular to a preparation method of a high temperature-resistant and ultra-narrow frame mobile phone touch screen. Background technique [0002] At present, the touch screen mainly adopts the structure of a glass base screen and a slurry protective screen. The inner surface of the glass base screen and the interlayer are coated with an ITO conductive layer. The four sides of the interlayer are provided with silver paste electronic circuits. The electronic circuit is connected to the ITO conductive layer on the sandwich layer, and then a protective layer of molten grout is applied on it. [0003] With the increasingly fierce competition in the touch screen market, narrow bezel design (that is, the narrow side of the non-visible area, especially the narrow side of the distributed electrode traces) has become a development trend, because the narrow bezel design can make the d...
