Abstract

The utility model discloses a resistance touch panel in a large scale, comprising a basal layer and an inner conductive coating arranged on the outer surface of the basal layer, a scraping prevention plastic coating and an outer conductive coating arranged on the inner surface of the scraping prevention plastic coating and isolation points arranged between the inner and the outer conductive coatings. The outer conductive coating and the inner conductive coating both include multi-piece conductivity modules with mutual lap joints. The external peripheries of the two conductivity modules which are in the longest distance along X-orientation of the outer conductive coating are separately provided with electrodes perpendicular to X-orientation, forming rectilinear form electrodes which are connected with each other. The external peripheries of the two conductivity modules of the inner conductive coating, which are in the longest distance along Y-orientation perpendicular to X-orientation of the outer conductive coating are separately provided with electrodes perpendicular to Y-orientation, forming rectilinear form electrodes which are connected with each other, thereby avoiding generating blind areas and improving the utilizing effect of the touch panel in a large scale because the electrodes of neighbor edges of the two neighbor conductivity modules don't exist.

Description

A kind of resistance-type large scale touch-screen

Technical field

The utility model relates to a kind of resistance-type large scale touch-screen.

Background technology

Only be 600 millimeters owing to be used to make the breadth extreme of the conduction mould of resistive touch screen at present, therefore if the bigger touch-screen of will quadraturing can only be by the splicing realization of conduction mould, when the conduction mould is stitched together, can form " dead band " at the electrode place, make like this and also the dead band can occur on the present screen that splices the large scale touch-screen that by the conduction mould, with reference to figure 2, and then cause the practical effect of large scale touch-screen undesirable.

Summary of the invention

The purpose of this utility model is to provide a kind of result of use large scale resistance formula touch-screen preferably.

For achieving the above object, the resistance-type large scale touch-screen that the utility model provides, comprise basic unit (lower floor), upper strata and be arranged on isolating points between the levels, described lower floor and upper strata include the conduction mould that polylith overlaps mutually, in the left and right edges of the conduction mould of described lower floor the electrode of vertical direction is set respectively, described electrode is linearly and interconnect; Lower limb is provided with the electrode of horizontal direction respectively on the conduction mould on described upper strata, and described electrode is linearly and interconnect.

The described the upper and lower of such scheme are rectangle.

The purpose of this utility model can also realize like this: a kind of resistance-type large scale touch-screen, comprise basic unit (lower floor), upper strata and be arranged on isolating points between the levels, described lower floor and upper strata include the conduction mould that polylith overlaps mutually, lower limb is provided with the electrode of horizontal direction respectively on the conduction mould of described lower floor, and described electrode is linearly and interconnect; In the left and right edges of the conduction mould on described upper strata the electrode of vertical direction is set respectively, described electrode is linearly and interconnect.

The described the upper and lower of this programme also are rectangle.

According to scheme of the present utility model, the lower floor of described large scale touch-screen and upper strata include the conduction mould that polylith overlaps mutually, (up and down) edge is provided with the vertically electrode of (level) direction respectively about the conduction mould of described lower floor, and described electrode is linearly and interconnect; About the conduction mould on described upper strata (about) edge is provided with the electrode of level (vertically) direction respectively, described electrode is linearly and interconnect, like this, owing to do not face the electrode that faces the edge mutually of two conduction moulds mutually, avoid the generation in dead band, and then improved the practical effect of large scale touch-screen.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model provides resistance-type pressure touch-screen, and it is that armrest refers to etc. that any energy directly clicks input information with the article of tens gram pressure for touch-screen on screen.Principle of the present utility model is with reference to figure 1, its screen body portion is a multi-layer compound film that cooperates very much with display surface, by one deck glass or organic glass as basic unit (lower floor) 1, the surface scribbles the conductive layer 2 of layer of transparent, be stamped one deck outside surface above again through cure process, smooth scratch resistant plastic layer (upper strata) 3, its inside surface also scribbles layer of transparent conductive layer 4, is provided with many tiny transparent isolating points 5 between two conductive layers they are separated insulation.

Principle of work of the present utility model is: when the striking touch-screen, the two conductive layers of mutually insulated has just had a contact under the normal condition in the position, touch point, cause is the even voltage field of a conductive layer connection Y direction wherein, 5 volts voltage field for example, another layer becomes non-zero as the voltage that the detecting layer records by zero, the controller of touch-screen carries out analog to digital conversion, and the magnitude of voltage that obtains is compared the Y-axis coordinate that can obtain touch-screen with 5 volts of voltages after receiving this connection; According to the coordinate that in like manner also can draw X-axis, thereby determine the touch point.

Lower floor 1 of the present utility model and upper strata 3 include the conduction mould that polylith overlaps mutually, in the left and right edges of the conduction mould of described lower floor 1 electrode 6,7 of vertical direction are set respectively, and described electrode 6,7 is linearly and interconnect, with reference to Figure 32; Lower limb is provided with the electrode 8,9 of horizontal direction respectively on the conduction mould on described upper strata 3, and described electrode 8,9 is linearly and interconnect, with reference to Figure 31.

Described lower floor and upper strata are rectangle.

Figure 33 is the upper and lower layer of a utility model embodiment electrode graph of a relation.Figure 31 represents horizontal direction and vertical direction respectively to X described in Figure 33 and Y direction.

The utility model also provides and similar second sets of plan of such scheme.The described resistance-type large scale of this scheme touch-screen also comprises basic unit (lower floor), upper strata and is arranged on isolating points between the levels, described lower floor and upper strata include the conduction mould that polylith overlaps mutually, different with first sets of plan is, lower limb is provided with the electrode of horizontal direction respectively on the conduction mould of described lower floor, and described electrode is linearly and interconnect; In the left and right edges of the conduction mould on described upper strata the electrode of vertical direction is set respectively, described electrode is linearly and interconnect; Certainly the described the upper and lower of this programme also are rectangle.
