Abstract

The invention provides a leveling process for a screen printed supporting point of a touch screen. The leveling process is characterized by comprising the following steps of: (1) performing a process before screen printing; (2) performing screen printing of a supporting point on an ITO (Indium Tin Oxide) conductive substrate; (3) horizontally standing the ITO conductive substrate with the screen-printed supporting point for 3-5 minutes; and (4) curing the supporting point of the ITO conductive substrate. When the touch screen produced by using the leveling process for the screen printed supporting point of the touch screen is in use, the ITO conductive substrate is not scratched by the screen printed supporting point, the supporting point is firm, and the product reliability is high.

Description

Touch-screen wire mark strong point levelling technology

Technical field

The present invention relates to a kind of touch-screen and make flow process, particularly relate to a kind of touch-screen wire mark strong point levelling technology.

Background technology

At present; In order to prevent resistive touch screen because of the distortion of ITO conductive base, cause two-layer ITO contact conducting when not having pressed by external force, cause touch function to lose efficacy; Usually in the resistive touch screen manufacture craft; The wire mark strong point between glass ITO conductive substrate and ITO film, the strong point of wire mark are insulating materials, the effect of between ITO conductive substrate and ITO film, playing support, separating.

Traditional touch screen wire mark strong point technology is: operation before the wire mark → wire mark strong point → curing, in touch-screen wire mark strong point technical process, be cured processing behind the wire mark strong point immediately, and like this, On-line Product stock is few, and production efficiency is high.But, because the strong point of wire mark has certain height, when behind wire mark, opening the seal net; The effect of seal net and the strong point can make point-like figure surface that wire mark comes out by wire drawing, and the wire drawing part mostly is sharp keen corner angle (referring to Fig. 1), like rapid curing this moment; The wire drawing part is also hardened; When touch-screen used at the terminal, the sharp keen corner angle of wire drawing part can be touched damage ITO conductive base, especially use case hardness to be conductive base as the ITO film of 3H; More general by touching damage phenomenon, be that the film off normal is touched in the part thereby cause straight-forward phenomenon.

Summary of the invention

The purpose of this invention is to provide a kind of touch-screen wire mark strong point levelling technology; Adopt the touch-screen of this touch-screen wire mark strong point levelling explained hereafter, in use, the strong point of wire mark can scratch ITO conductive base; The strong point is firm, and product reliability is high.

In order to achieve the above object, touch-screen wire mark strong point levelling technology of the present invention is characterized in that:

1., operation before the wire mark;

2., the wire mark strong point on the ITO conductive base;

3., the level ITO conductive base 3 ~ 5 minutes of the strong point that left standstill wire mark;

4., solidify the strong point of ITO conductive base.

Because this touch-screen wire mark strong point levelling technology level behind the wire mark strong point leave standstill wire mark the ITO conductive base of the strong point solidify the strong point of ITO conductive base after 3 ~ 5 minutes again; The wire drawing meeting levelling on the strong point surface that wire mark comes out increases the contact area of the strong point and ITO conductive base, and the wire drawing part does not have sharp keen corner angle yet and exists; Both increased the adhesive force of the strong point and ITO conductive base; Touch-screen in use, the strong point of wire mark can scratch ITO conductive base, can not cause the strong point to come off because of excessive extruding force yet; The strong point is firm, and product reliability is high.

Operation is the preparatory process before the wire mark before the described wire mark.

The described strong point is that carbamate and acrylate are formed adhesive.

Adopt the touch-screen of touch-screen wire mark strong point levelling explained hereafter of the present invention, in use, the strong point of wire mark can scratch ITO conductive base, and the strong point is firm, and product reliability is high.

Description of drawings

Fig. 1 is that the strong point of wire mark does not leave standstill the sketch map after just solidifying.

Fig. 2 is the sketch map of the strong point after level leaves standstill 3 ~ 5 minutes of wire mark.

The specific embodiment

The description of symbols of Fig. 1: the strong point 1, wire drawing 2.

Referring to Fig. 2, touch-screen wire mark strong point levelling implementation of processes example of the present invention may further comprise the steps:

1., operation before the wire mark;

2., the wire mark strong point 1 on the ITO conductive base;

3., the level ITO conductive base 3 ~ 5 minutes of the strong point 1 that left standstill wire mark;

4., solidify the strong point 1 of ITO conductive base.

Because this touch-screen wire mark strong point levelling technology in the wire mark strong point 1 back level leave standstill wire mark the ITO conductive base of the strong point 1 solidify the strong point 1 of ITO conductive base after 3 ~ 5 minutes again; The wire drawing 2 meeting levellings on the strong point 1 surface that wire mark comes out increase the strong point 1 and the contact area of ITO conductive base, and wire drawing 2 parts do not have sharp keen corner angle yet and exist; Both increased the adhesive force of the strong point 1 with the ITO conductive base; Touch-screen in use, the strong point 1 of wire mark can scratch ITO conductive base, can not cause the strong point 1 to come off because of excessive extruding force yet; The strong point 1 is firm, and product reliability is high.

Among the embodiment, operation is the preparatory process before the wire mark before the wire mark, and the strong point 1 of wire mark is that carbamate and acrylate are formed adhesive.

Adopt the touch-screen of touch-screen wire mark strong point levelling explained hereafter of the present invention, in use, the strong point 1 of wire mark can scratch ITO conductive base; The strong point 1 is firm; Product reliability is high, and applying of this technology has positive meaning to the quality that improves touch-screen.
