Abstract
The invention provides a capacitive touch screen printed by conductive carbon paste. The capacitive touch screen comprises conductive carbon paste, a screen printing plate, a scraper and an ITO SENSOR. The conductive carbon paste is special printing ink and a main material for circuit bridging. A layer of mesh of a printing circuit is arranged on the screen printing plate. The printing ink seeps onto the ITO SENSOR through mesh holes. The scraper is special rubber and is used for scraping the printing ink to enable the printing ink to seep onto the ITO SENSOR. The ITO SENSOR is a circuit board of a glass base material and is used for arranging a circuit. The capacitive touch screen is simple in process and convenient to produce, space is saved, and cost is reduced.
Description
Technical field
The present invention relates to a kind of capacitance touch screen, particularly a kind of capacitive touch screen of conductive carbon paste printing.
Background technology
All be molybdenum aluminium molybdenum materials matter at the GLASS SENSOR part circuit of every projection-type capacitive touch screen on the market at present, its technological process is: at first coat photoresist having plated molybdenum aluminium molybdenum ITO GLASS surface, then hidden by the film, behind exposure imaging, strip molybdenum aluminium molybdenum again after being hidden the photoresist that is not exposed the position by the film and removing, after the cleaning, just stay needed circuit on ITO GLASS surface.
The defective of this technique have following some:
1, complex process requires very high to production environment;
2, technique is very high to the requirement of equipment, and production cost is relatively high;
3, processing step is many, to producing yield very big restriction is arranged.
Summary of the invention
In order to overcome the technical matters that exists in the prior art, the invention provides following technical scheme:
A kind of capacitive touch screen of conductive carbon paste printing, it comprises conductive carbon paste, half tone, scraper and ITO SENSOR, described conductive carbon paste is a kind of specialty inks, is the main material of circuit bridging; Described half tone is furnished with one deck grenadine of printed wire, and printing ink is seeped on the ITO SENSOR by the yarn hole of grenadine; Described scraper is a kind of special rubber, is used for scraping printing ink, makes it logical yarn passing hole and is seeped on the ITO SENSOR, and described ITO SENSOR is the wiring board of glass baseplate, in order to wiring topology.
As the preferred technical solution of the present invention, the manufacture craft of described touch-screen is: at first conductive carbon paste is coated on the half tone, next is transferred to printing ink on the ITO SENSOR by the line pattern on the half tone from left to right by scraper, dries finally by the overbaking baking box to get final product.
The contrast prior art, the beneficial effect that the present invention brings is: technique simply is convenient to produce, has saved the space, has been reduced cost.

Fig. 2 is right view of the present invention
Embodiment
The below is to elaborating preferred embodiment of the present invention by reference to the accompanying drawings, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention made more explicit defining.
Extremely shown in Figure 2 such as Fig. 1, a kind of capacitive touch screen of conductive carbon paste printing, it comprises conductive carbon paste, half tone 1, scraper 2 and ITO SENSOR 3, described conductive carbon paste is a kind of specialty inks, is the main material that circuit is put up a bridge; Described half tone 1 is furnished with one deck grenadine of printed wire, and printing ink is seeped on the ITO SENSOR3 by the yarn hole of grenadine; Described scraper 2 is a kind of special rubber, is used for scraping printing ink, makes it logical yarn passing hole and is seeped on the ITO SENSOR 3, and described ITO SENSOR 3 is the wiring board of glass baseplate, in order to wiring topology.The manufacture craft of described touch-screen is: at first conductive carbon paste is coated on the half tone, next is transferred to printing ink on the ITOSENSOR 3 by the line pattern on the half tone 1 from left to right by scraper 2, dries finally by the overbaking baking box to get final product.
The electrically conductive ink printing need not too many professional equipment because of it, some circuit board fabrication medium-sized and small enterprises can directly make the transition, so can better popularize, making it cost of products can descend to a great extent, also so that vast low and middle-end consumer also can enjoy convenient and joyful that the high-end science and technology in forward position brings, for popularizing and improving popular cultural life and opened up a platform.
The above; it only is one of the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
