Abstract
A wiring structure of an indium tin oxide (ITO) comprises a plurality of first sensing electrodes parallelly arranged in the first direction and a plurality of second sensing electrodes parallelly arranged in the second direction, wherein each first sensing electrode comprises a plurality of sensing electrode sections spliced in sequence, the edges of the sensing electrode sections extending in the first direction are curved, and the second sensing electrodes are rectangular and located under the first sensing electrodes. By means of the design of the curved edges of the first sensing electrodes, the problems of unclear displaying and glaring caused by the fact that an ITO layout structure is displayed completely are solved, and the second sensing electrodes are located under the first sensing electrodes, so that a self-shielding effect can be played, and the signal to noise ratio is improved.
Description
Technical field
The present invention relates to the wire structures of a kind of ITO, especially a kind of ITO wire structures of bilayer.
Background technology
At present, touch-screen is widely used in the fields such as instrument and meter, computing machine, electronic watch, game machine and household electrical appliance, and touch-screen generally includes display layer and the touch layer that is positioned on the display layer, and touch layer utilizes indium tin oxide ITO to make usually.Existing a kind of ITO wire structures, the the second touch-control electrode that comprises several first transversely arranged touch-control electrodes and several longitudinal arrangements, described the first touch-control electrode laterally connects, described the second touch-control electrode vertically connects, described the first touch-control electrode and described the second touch-control electrode are hexagon, and the transverse width of described the first touch-control electrode is greater than vertical width, vertical width of described the second touch-control electrode is filled with the suspension piece greater than transverse width in the zone that described the first touch-control electrode and the second touch-control electrode surround.Existing ITO wire structures, in use, the touch layer electrode structure can clearly show, and affects the display effect of display layer, causes the demonstration of display layer unclear, and can produce dazzle, causes visual discomfort.And the wire structures of the ITO of existing touch-screen needs to increase in addition screen layer and shields extraneous noise, especially from the noise of display layer, can not realize reaching by the structure of ITO itself purpose of shielding noise.
Summary of the invention
Technical matters to be solved by this invention is to show problem unclear and dazzle because the ITO wire structures causes, and problem that can not the self-shileding noise.
To achieve these goals, the invention provides the layouts of a kind of ITO, it is included in several first induction electrodes that first direction is arranged in parallel and several second induction electrodes that are arranged in parallel in second direction, described the first induction electrode comprises the induction electrode joint that several engage successively, described induction electrode joint is curve at the upwardly extending edge of first party, described the second induction electrode is rectangle, is positioned at the first induction electrode below.
Compared with prior art, the edge of the first induction electrode of the present invention is Curve Design, solved and shown that fully the caused demonstration of ITO layouts do not know problem and glare problem, and the second induction electrode is the below with described the first induction electrode, can play the effect of self-shileding, improve signal to noise ratio (S/N ratio).
Description of drawings
Fig. 1 is the synoptic diagram of ITO wire structures of the present invention.
Fig. 2 is its wire structures of ITO layer at the middle and upper levels of ITO wire structures of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, synoptic diagram for ITO wire structures of the present invention, it is double-decker, comprise several the first induction electrode 1 and several second induction electrodes 2, described the first induction electrode 1 is arranged in parallel at first direction, described the second induction electrode 2 is arranged in parallel in second direction, and described first direction is perpendicular to second direction.Be filled with several suspension pieces 3 between described the first induction electrode 1, leave the space between the described suspension piece 3, the increase of suspension piece can improve the linearity.
Described the first induction electrode 1 comprises several induction electrode joints 10, described induction electrode joint 10 engages on first direction successively, and described induction electrode joint 10 is level and smooth curve in the upwardly extending both sides of the edge 11 of first party, described smooth curve can be formation that cave inward of the both sides of the edge 11 of described induction electrode joint 10, also can be that described induction electrode saves 10 both sides of the edge 11 outwardly formation.The edge 30 that described suspension piece 3 is adjacent with described the first induction electrode 1 equally also is curve, and and described the first induction electrode 1 between the gap be equidistant.It is corresponding with the both sides of the edge 11 of described induction electrode joint 10 that described suspension piece 3 and described induction electrode save 10 adjacent edges 30, even described induction electrode joint 10 formation that caves inward at the upwardly extending edge 11 of first party, described suspension piece 3 saves the 10 adjacent curves of edge 30 for outwards giving prominence to described induction electrode, if described induction electrode joint 10 is in first party upwardly extending edge 11 outwardly formation, described suspension piece 3 saves the 10 adjacent curves of edge 30 for caving inward with described induction electrode.The Curve Design of described the first induction electrode 1 and described suspension piece 3 can solve dazzle and show unclear problem.Described the second induction electrode 2 is rectangle, quantity on first direction is single, width is slightly less than the length of described induction electrode joint 10, suitable with the width between the outer ledge of the suspension piece between two induction electrodes joint 10, its length can cover all induction electrode joints of arranging on the first direction, and described the second induction electrode 2 is positioned at the below of described the first induction electrode 1, can shield and come from the outside especially owing to show caused noise, improve signal to noise ratio (S/N ratio), realize the effect of self-shileding.Described the first induction electrode 1 and described the second induction electrode 2 all have certain width, can reduce impedance.
Compared with prior art, ITO wire structures of the present invention can clearly not manifest the wire structures of ITO by adopting the design of curve, and the demonstration that makes is clearer, does not allow the dazzle of people's eye discomfort.
