Description

The wire structures of a kind of ITO

Technical field

The present invention relates to the wire structures of a kind of ITO, particularly relate to the wire structures of a kind of ITO of touch-screen.

Background technology

So-called ITO(indium tin oxide) be a kind of critical material for the production of liquid crystal display, at present, it has had in fields such as instrument and meter, computing machine, electronic watch, game machine and household electrical appliance very widely uses.The capacitive touch screen of large heat also is to utilize ITO to finish the action that detecting touches on the market in recent years.

Existing touch-screen comprises substrate and double-deck ITO, and the paving mode of double-deck ITO has two kinds, and a kind of ITO of being layer is laid on the bilateral of substrate, and wherein an ITO layer is the X-axis detection layers, and another ITO layer is the Y-axis detection layers; Another kind of is the same side that two-layer ITO layer all is laid on substrate, for fear of the mutual conduction between the electrode, at substrate bridge contact is set, thereby has effectively avoided the short circuit between the electrode.Which kind of mode no matter, the wire structures of existing ITO is generally rhombus, although it is simple in structure, can finish the action that touches detecting, but owing to adopt diamond structure, can bring unavoidably to refer to that touch detection is unstable, power supply noise disturbs problem large, the setting-out poor effect more, affect user's result of use.

Therefore need to solve the problems referred to above for users provide a kind of brand-new ITO wire structures.

Summary of the invention

The technical matters that the present invention mainly solves provides the wire structures of a kind of ITO, can improve the not high problem of conventional condenser touch-control structure detecting sensitivity, and antijamming capability is stronger, and the linearity is higher.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the wire structures that a kind of ITO is provided, comprise two-layer ITO, all be laid on the substrate, the wire structures of described ITO comprises several electrode blocks, described electrode block forms groined type by X electrode and Y electrode, and is filled with several suspension pieces in the space between described X electrode and described Y electrode.

The invention has the beneficial effects as follows: although the present invention is simple in structure, but signal intensity obviously strengthens, can improve not high problem and the suspension problem of conventional condenser touch-control structure detecting sensitivity, obviously improve sensitivity, the linearity, communication speed and the water resistance of ITO layer.Fill the suspension piece in the space between electrode, increased capacitive coupling, thereby strengthened the antijamming capability of whole ITO layer.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, 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 is made more explicit defining.

See also Fig. 1, the embodiment of the invention comprises:

The wire structures 1 of a kind of ITO comprises two-layer ITO, all is laid in the substrate homonymy, is laid with X electrode 13 on one deck ITO, is laid with Y electrode 12 on another layer ITO.The wire structures of described ITO comprises several electrode blocks 10, described electrode block 10 forms groined type by X electrode 13 and Y electrode 12, described X electrode 13 and Y electrode 12 form by several electrode units 100, if interconnect at the above electrode unit 100 of directions X, interconnect in the mode of the above electrode unit 100 of Y-direction by bridge joint so, thereby effectively avoided short circuit between the electrode.

See also Fig. 2, an electrode block 10 comprises two row X electrode 13 and Y electrodes 12, forms the space between the adjacent two row electrodes.Every row X electrode 13 comprises two electrode units 100, and every row Y electrode 12 comprises two electrode units 100.Described electrode unit 100 be shaped as hexagon, wherein hexagonal diagonal line is than other length of side, and the length of side of hexagon longer sides is decided according to the design requirement of the ITO inductive layer of touch-screen, and the structure but whole electrode block 10 is centrosymmetric is so that the ITO layer has uniform sensing capability.The capacitive load of each electrode block 1 obviously reduces with respect to the capacitive load of conventional condenser touch-control structure, thereby the signal intensity of whole ITO layer is obviously strengthened, and has improved the communication speed of ITO layer.

Be filled with several suspension pieces 11 in the space between described X electrode 13 and described Y electrode 12, described suspension piece 11 also is ITO, can increase capacitive coupling so, strengthen the antijamming capability of described whole ITO layer, also obviously improved sensitivity, the linearity and the water resistance of ITO layer simultaneously.In order clearly to express the number of the suspension piece 11 of filling in the space between the adjacent electrode, see also Fig. 3, space difference label with an electrode block 1 interior X electrode 13 and Y electrode 12 compositions, the space that is positioned at electrode block 10 centers is a district, in a district, be filled with even number suspension piece 11, at least be filled with four suspension pieces 11, increase progressively with this and form a suspension block matrix; The number that is positioned at b district, the space filling suspension piece 11 of electrode block 10 edges is half of a district suspension piece 11 numbers; The number that is positioned at the c district filling suspension piece 11 at 1 four jiaos of places of electrode block is half of b district suspension piece 11 numbers, forms the whole ITO layer of symmetrical structures with these several electrode blocks 1.

Be arranged in the electrode block 10 of ITO edge, the lead-in wire of adjacent two X electrodes 13 or Y electrode 12 is interconnected to a pin of touch-control chip, so an electrode block 10 respectively has an X lead-in wire and Y lead-in wire to be connected on pin corresponding to touch-control chip.
