Description

A kind of touch-screen with double-deck circuit

Technical field

The utility model relates to a kind of touch-screen, refers to especially a kind of touch-screen with double-deck circuit.

Background technology

Touch-screen is a kind of simple, convenient, natural human-computer interaction device, and it has been widely used in various places.Touch-screen is of a great variety, divides by principle mainly to comprise resistance-type, condenser type, infrared type and surface acoustic wave type.The capacitance plate of main flow generally adopts the capacitance plate (multi-point touch) of double-deck toughened glass panel (g+g) at present; in order to make capacitance plate further frivolous; can on cover glass, directly form the technology of ITO conducting film and sensor; a glass plays the double action of cover glass and touch sensor simultaneously; it is integrated touch-control; One Glass Solution is called for short OGS.OGS will become the dominant technology direction of touch-control industry, and its main benefit has 3 points: 1) saved one deck glass cost and reduced the cost of once fitting; 2) alleviated weight; 3) increased penetrability.OGS can satisfy intelligent terminal ultrathin demand preferably, and promotes display effect.

But, projection-type mutual capacitance screen needs two conductive layers to come circuit etching, every layer of conductive layer can etch the path of several separate insulation, wherein the path on one deck is used for doing T (transmission) passage transmitted signal, and another sandwich circuit is used for doing R (receive) channel receiving signal.T passage and R channel direction interlaced (general mutual homeotropic alignment), and want mutually insulated between T passage and the R passage, namely middle must have non-conductive medium to keep apart.If directly use two conductive layers, increased thickness and cost, and the OGS structure does not match.If T passage and R passage are accomplished on the same aspect, then to adopt gold-tinted processing procedure bridging technique, its structure as shown in Figure 1, T passage 5 is positioned at same conductive layer with R passage 6.Specific practice is: the figure that at first etches T passage 5 and R passage 6 at the same layer conducting film, but it is conducting that two kinds of passages only have a kind of passage in staggered place, another passage disconnects herein, then plate insulation course 6 in the staggered place, at insulation course 6 usefulness connecting conductive layers the R or the T passage that disconnect are coupled together to reach the conducting effect again.The capacitance plate principal feature of this class formation is: 1) R passage and T passage only need one deck conductive layer; 2) megohmite insulant is distributed in the place that whole active region T passage and R passage cross; 3) because insulation course and connecting conductive layer are positioned at the viewing area, so megohmite insulant and the conductive materials of upper connection of iting will be accomplished not visible.Its shortcoming is: 1) the disposable input of machinery and equipment is huge; 2) the visual effect of product is bad; 3) technique relative complex, difficulty is large.

The utility model content

The utility model proposes a kind of touch-screen with double-deck circuit, can realize that not only the individual layer multipoint mode touches structure, and technique is simple, visual effect is good.

The technical solution of the utility model is achieved in that a kind of touch-screen with double-deck circuit, comprise substrate, be distributed with the conducting wire layer on the described substrate, wherein, described conducting wire layer comprises the first conducting wire layer and the second conducting wire layer, is provided with the dielectric ink layer between described the first conducting wire layer and the second conducting wire layer.

Further, described the first conducting wire layer, dielectric ink layer and the second conducting wire layer are deposited on substrate successively by mode of printing.

Further, the material of described substrate is PET plastics or glass baseplate.

The utility model contrast prior art has following beneficial effect: the utility model provides has touch-screen of double-deck circuit and preparation method thereof, by printing dielectric ink layer the first conducting wire layer and the second conducting wire layer are isolated, thereby realize that the individual layer multipoint mode touches structure, and technique is simple, and visual effect is good.
