Description
Technical field
The present invention relates to the electrode lay-out of a kind of touch screen, the electrode lay-out of a kind of capacitance touch screen.
Background technology
Along with the development of science and technology, touch screen the most gradually replaces mechanical botton panel becomes the operation interface that the electronic equipment such as mobile phone, notebook is new.Touch screen includes resistive touch screen, infrared touch panel, capacitive touch screen, and they obtain coordinate by the way of different, and capacitive touch screen is due to its light transmittance, definition and better reliability, and are applied in increasing product.
One important composition structure of capacitance touch screen is exactly electrode lay-out, existing frequently-used capacitance touch screen electrode lay-out includes X-axis induction electrode and Y-axis induction electrode, described X-axis induction electrode is identical with described Y-axis induction electrode shape is rhombus, it is arranged in order with the form of several rows and some row, and string X-axis induction electrode and string Y-axis induction electrode alternately arranged, wherein it is connected with the X-axis induction electrode of string, is connected with the Y-axis induction electrode of a line.Although above-mentioned electrode lay-out structure is simple, but user is when using touch screen, it may appear that when the problem of suspension, even subscriber station directly operate touch screen in big ground on palm, owing to human body is directly grounded, so the sensitivity of touch screen is preferable；If user uses touch screen in car, owing to now user can not be directly grounded, so the sensitivity of touch screen can decline.Therefore, if changing the use environment of touch screen, it is possible to cause the suspension problem of touch screen.
It is therefore desirable to provide a kind of can reduction even to avoid the electrode lay-out of touch screen suspension problem for users.
Summary of the invention
The technical problem to be solved is to provide a kind of electrode lay-out reducing touch screen suspension problem.
To achieve these goals, the present invention provides the electrode lay-out of a kind of touch screen, described touch screen mainly includes substrate and the electrode layer being located on substrate, described electrode layer is provided with cover plate, described cover plate is provided with LCDs, described electrode layer is made up of some electrodes assuming diamond in shape combination shape, and it is respectively along longitudinal direction and the lateral cross arrangement of substrate, and described electrode part is Openworks shape.
Compared with prior art, the electrode lay-out of touch screen of the present invention, owing to electrode part is Openworks shape, so solving the suspension problem of touch screen, and the linearity of touch screen there has also been and is substantially improved；Furthermore, the width of described peripheral rhombus is arranged to identical with the width of described cover plate, not only ensure that when signal transmits higher, and make the compatible enhancing of cover plate, and also enhance the compatibility between electrode layer and LCDs.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of embodiment of the present invention part inductive layer wire structures.
Fig. 2 is first embodiment of the electrode lay-out according to touch screen of the present invention.
Fig. 3 is second embodiment of the electrode lay-out according to touch screen of the present invention.
Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
Incorporated by reference to reference to shown in Fig. 1 and Fig. 2, the present invention relates to the electrode lay-out of a kind of touch screen, described touch screen 1 mainly includes substrate 10 and the electrode layer 11 being located on substrate 10, and described electrode layer 11 is provided with cover plate 12, and described cover plate 12 is provided with LCDs 13.Described electrode layer 11 is made up of some electrodes 110 assuming diamond in shape combination shape, and it is respectively along longitudinal direction and the lateral cross arrangement of substrate 10, described electrode layer 11 both can be laid in the upper and lower both sides of described substrate 10 respectively also can be laid in the homonymy i.e. upside of described substrate 10, now also needs to be provided with insulating barrier between two electrode layers 11.Either electrode layer 11 is arranged on both sides or the homonymy of described substrate 10, all can connect two electrode layers 11 by the way of bridge contact is set.
Refer to shown in Fig. 2, described electrode 110 by peripheral rhombus 110A and in enclose the structure of rhombus 110B and form, wherein in enclose rhombus 110B and be hollowed out, in Openworks shape, and the width of described peripheral rhombus 110A is identical with the width of described cover plate 12.Being Openworks shape owing to enclosing rhombus 110B in described electrode 110, so solving the suspension problem of touch screen, and the linearity of described touch screen there has also been and is substantially improved；And the width of described peripheral rhombus 110A is identical with the width of described cover plate 12, thus higher during signal transmission, so that the compatible of cover plate 12 strengthens, furthermore, now electrode layer 11 also strengthens with the compatibility of LCDs 13.
In the electrode lay-out of above-mentioned touch screen, enclosing rhombus 110B in described electrode 110 is Openworks shape, so creating beyond thought advantage for more traditional solid diamond structure.In view of this technical characteristic, the present invention can be done deformation further, refer to shown in Fig. 3, described electrode 110 by peripheral rhombus 110A, middle rhombus 110C, in enclose the structure of rhombus 110B and form, wherein, middle rhombus 110C peripherally located rhombus 110A and interior enclose between rhombus 110B, and described middle rhombus 110C is hollowed out, in Openworks shape.Due to described peripheral rhombus 110A with interior enclose rhombus 110B all in closed diamonds structure, so the suspension problem of touch screen also can be solved.Now, if the width of described peripheral rhombus 110A is identical with the width of described cover plate 12, also can guarantee that when signal transmits higher, and make the compatible enhancing of cover plate 12.
The electrode lay-out of touch screen of the present invention, is hollowed out the inside of classic diamond shape shape electrode structure so that it is part is in Openworks shape, so solving the suspension problem of touch screen, and the linearity of touch screen there has also been and is substantially improved；Furthermore, the width of described peripheral rhombus is arranged to identical with the width of described cover plate, not only ensure that when signal transmits higher, and make the compatible enhancing of cover plate 12, and also enhance the compatibility between electrode layer and LCDs.
