Description
[technical field]
The utility model relates to touch-screen, refers more particularly to a kind of multi-point touch panel of the touch location separately can discern multiple spot and touch simultaneously the time.
[background technology]
Rise day by day and handheld input device update along with the multimedia information inquiry business, touch-screen is just accepted by increasing people as a kind of input equipment simple to operate, easy to use, it has given the most natural a kind of man-machine interaction mode in the message exchange field, is attractive brand-new multimedia interactive equipment.
Different according to touch-screen principle and transmission medium, touch-screen can be divided into resistance-type, capacitor induction type, infrared-type and surface acoustic wave type or the like, if divide according to the touch point number, can be divided into single-point and multiple point touching mode again.Even the problem that traditional four-wire resistance type, infrared-type and surface acoustic wave type exist is a sensing surface when a plurality of target is arranged, they also only can report a point, also are that their lack the ability of following the trail of a plurality of touch points simultaneously.Do not support the above touch of or multiple spot can limit the use of touch-screen to a certain extent at 2.Though the multi-point tracking ability is arranged in the capacitor induction type touch-screen, the interference that it is subjected to external condition easily makes job insecurity.Some resistor matrix formula touch-screens are also arranged now, it has multi-touch function, yet all there is contact conductor at every column electrode or row electrode two ends, like that the touch-screen of cutting apart for high resolving power, its lead-in wire of drawing relatively is more, and then makes that difficulty is bigger when routing of layout.
[utility model content]
At the more defective of the contact conductor of drawing relatively in the prior art, the utility model provides a kind of multi-point touch panel that reduces contact conductor to a certain extent.
A kind of multi-point touch panel that this utility model provides, it comprises transparent medium supporting layer and following transparent medium supporting layer, described upward transparent medium supporting layer and following transparent medium supporting layer are by being provided with connector to form a cavity at edge respect to one another, in described cavity, the downside of transparent medium supporting layer is provided with the first rectangle transparency conducting layer on described, be provided with the second rectangle transparency conducting layer vertical at the described upside of transparent medium supporting layer down with the described first rectangle transparency conducting layer, be provided with isolated area between the described first adjacent rectangle transparency conducting layer or the second rectangle transparency conducting layer, and between the described first rectangle transparency conducting layer and the second rectangle transparency conducting layer, be provided with transparent insulating layer, wherein, the described first rectangle transparency conducting layer spaced apart or the second rectangle transparency conducting layer are electrically connected with the form of " S " type or anti-" S ", and go between at the protuberance and the single place of the drawing difference extraction electrode of described " S " type or anti-" S " type first rectangle transparency conducting layer or the second rectangle transparency conducting layer both sides.
With respect in the prior art for the first rectangle transparency conducting layer in the touch-screen and the second rectangle transparency conducting layer, its two ends separately all need to draw respectively an electrical leads, make contact conductor too much, and then make when designing wiring because the problem that contact conductor is too much so that wiring is comparatively difficult, adopt the described first rectangle transparency conducting layer or the second rectangle transparency conducting layer are electrically contacted with the form of " S " type or anti-" S ", and the method for distinguishing the extraction electrode lead-in wire at the protuberance and the single place of drawing of described " S " type or anti-" S " type first rectangle transparency conducting layer or the second rectangle transparency conducting layer both sides, make the quantity of its contact conductor with respect to prior art, reduce half, thereby reduced the cost of saving because of the minimizing of contact conductor to a certain extent, also reduced the difficulty when arranging the contact conductor cabling simultaneously.
Feature of the present utility model and advantage will be elaborated in conjunction with Figure of description by embodiment.
