Embodiment
For setting forth more clearly thought of the present invention, the below will contrast the touch induction device of prior art and introduce specifically embodiment of the present invention, in the prior art with preferred implementation of the present invention in similar elements adopt identical title and label.
Such as Fig. 1, the capacitance touch induction installation of prior art is formed by stacking by testing circuit and the different a plurality of working linings of function usually hereinafter to be referred as touch induction device, and working lining can comprise display layer, electrode layer, insulation course, screen layer etc. usually.Its function and principle all are that the people in the industry is known, other working linings are not done too much to introduce at this, introduce the induction electrode layer.
In this exemplary prior art, touch induction device comprises two induction electrode layers, is respectively the first electrode layer 1 and the second electrode lay 3.Each induction electrode layer is provided with many induced electricity polar curves, and every induced electricity polar curve all is electrically connected in the testing circuit layout parallel to each other.In conjunction with Fig. 2 and shown in Figure 3, the first electrode layer 1 is provided with many induced electricity polar curves that extend along first direction, is called the first electrode wires 5, and the second electrode lay 3 is provided with many induced electricity polar curves that extend along second direction, is called the second electrode wires 7.Wherein, every induced electricity polar curve includes electrode block 9 and the connecting line that interlaced connection arranges, and electrode block 9 can be rhombus for figures such as square, rectangle, regular hexagons in this example, and the rhombus connection has less connection resistances; Connecting line is linear.Preferably, first direction is mutually vertical with second direction, and namely the bearing of trend of the induced electricity polar curve on the bearing of trend of the induced electricity polar curve on the first electrode layer 1 and the second electrode lay 3 is vertical.First direction is the X direction of display screen, i.e. X-direction, and second direction is the y direction of display screen, i.e. Y direction.Such two electrode layers detect respectively X-axis coordinate and the Y-axis coordinate of touch area, and convenient follow-up processing is calculated.In this example, electrode layer is etching ITO layer.
By Fig. 2 and Fig. 3 as seen, the shape of many induced electricity polar curves of each electrode layer is identical with the position, distance is also fixed, thereby the electrode block 9 of many induced electricity polar curves toward each other, connecting line also toward each other, formed the larger zone line of not arranging electrode between the induced electricity polar curve, because electrode block 9 shapes on each induced electricity polar curve are identical with the position, zone line is divided into a plurality of blank blocks that communicate with each other.And after two stacked closing of induction electrode, the electrode block 9 of the first electrode layer 1 and the second electrode lay 3 is positioned at the zone line of relative induction electrode layer each other, namely each electrode block of the first electrode layer is stacked in the zone line position of the second electrode block, and each electrode block of the second electrode lay is stacked in the zone line position of the first electrode block.Because in each electrode layer, have the part of electrode block 9 different with the refractive index of the part that does not have electrode block 9, causing electrode block 9 is visible in some cases, has affected the display effect of touch induction device.
In order to address the above problem, avoid electrode block 9 to affect display effect, the present invention improves prior art by following embodiment.
Such as Fig. 4, improved touch induction device has all parts of above-mentioned exemplary prior art, such as the first electrode layer 1, the second electrode lay 3 etc., but also is provided with the electrode 11 that swims between the induced electricity polar curve in each induction electrode layer.
With reference to Fig. 5 and Fig. 6, the zone line of electrode 11 between a plurality of induced electricity polar curves of each electrode layer that swim, the electrode 11 that swims is filled full described zone line, and the distance between the electrode block 9 is less than 50 μ m, preferably less than 30 μ m, surpassed human eye can identification the limit.Preferably, fill completely described zone line by the mode of in each blank block 9, all placing the electrode 11 that swims, and the electrode 11 that swims is identical with the material of electrode block 9.Thereby, on the whole electrode layer except human eye can not the slit of identification, the refractive index of each position is identical, the problem of having avoided electrode to be identified by naked eyes.
The electrode 11 that swims is not connected with testing circuit, electrical isolation with it, and do not connect mutually each other, do not consist of induction electrode.
Concrete, between each first electrode wires 5 in the first electrode layer 1 in the formed blank block, be provided with the electrode 11 that swims, for the convenience of taking into account manufacturing and the filling rate of blank block, the electrode design of swimming becomes regular hexagon, and the slit between electrode 11 and the adjacent electrode block 9 of so still can guaranteeing to swim is all less than 30 μ m.Certainly, the shape that is designed to other also is feasible, for example, is designed to the asymmetric octagon of fitting fully with the shape of blank block.Each electrode that swims also can couple together, and forms the electrode wires of swimming, and with the induction electrode line parallel zone line between each first electrode wires 5 of so better filling is set.
In the formed blank block, be provided with equally the electrode that swims between each second electrode wires 7 in the second electrode lay 3, do not repeat them here.
Simultaneously, for the refraction that the section difference band that further reduces electrode layer comes, the thickness of electrode layer should be less than 60 μ m, preferably less than 50 μ m.
