specific Embodiment approach 1

[0043] Specific implementation mode 1: In this implementation mode, the manufacturing process of the high-hardness anti-fingerprint ultra-narrow frame mobile phone touch screen is realized according to the following steps:

[0044] Step 1. Glass substrate 1 processing

[0045] Prepare the glass substrate 1, process two semicircular grooves equal to the length of the glass substrate 1 on the upper surface of the glass substrate 1; the grooves are parallel to the length direction of the glass substrate 1, and the two grooves are respectively arranged on the glass substrate Edges on both sides of the upper surface;

[0046] Step 2, preparing the first ITO conductive layer 2

[0047] Coating the first ITO conductive layer 3 on the lower surface of the glass substrate 1;

[0048] Step 3, preparing the second ITO conductive layer 3

[0049] Coating a second ITO conductive layer 3 on the upper surface of the glass substrate 1 and the upper surface of the groove;

[0050] Step 4. ...

specific Embodiment approach 2

[0061] Embodiment 2: This embodiment differs from Embodiment 1 in that: the glass substrate 1 in step 1 is a tempered glass substrate, strengthened glass substrate, common glass substrate or a transparent polymer material substrate. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0062] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the electronic circuit 6 in Step 5 is made of carbon paste or silver paste. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to the field of touch screens, in particular to a preparation technology of a high-hardness anti-fingerprint ultra-narrow border mobile phone touch screen. The preparation technology solves the problems that the requirement of a narrow border cannot be met and the touch screen is likely to scratch and is easily contaminated by fingerprints under the condition that the quantity of electrode routings is unchanged in the prior art. The preparation technology comprises the following steps: step one, treating a glass substrate; step two, preparing a first ITO conducting layer; step three, preparing a second ITO conducting layer; step four, preparing an SiO2 protective layer; step five, preparing an electronic circuit; and step six, preparing an anti-fingerprint coating. The high-hardness touch screen can be prepared, the touch screen can be prevented from being scratched, a narrower border and an anti-fingerprint coating function can be realized, the manufacturing method is relatively simple, and the cost is relatively low. The preparation technology is suitable for preparing the touch screen.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a preparation process of a high-hardness anti-fingerprint ultra-narrow frame mobile phone touch screen. Background technique [0002] At present, the touch screen mainly adopts the structure of the glass-based screen and the protective screen of the melted slurry. The inner surface of the glass-based screen and the interlayer are each coated with a layer of ITO conductive layer, and the four sides of the interlayer are provided with silver paste electronic circuits. The electronic circuit is connected with the ITO conductive layer of the interlayer, and then a protective layer of fused slurry is coated on it. However, due to the hardness of the slurry-slurry protective layer can only reach Mohs 4H hardness, it cannot reach SiO 2 The Mohs hardness is 7H. If people operate the touch screen, hard objects are easy to scratch the protective layer of the slurry, so that the touch screen ...
