Description
Technical field
The present invention relates to a kind of electrode lay-out of touch-screen, refer in particular to the electrode lay-out of capacitive touch screen.
Background technology
Along with the development of science and technology, touch-screen has replaced the mechanical type push button panel gradually becomes the new operation interfaces of electronic equipment such as mobile phone, notebook.At present, touch-screen mainly comprises resistive touch screen, infrared touch panel and capacitive touch screen, and they all obtain coordinate by different modes.Thereby and capacitive touch screen be by touch object as the conductive material such as finger, pointer near or the touching touch-screen capacitance of touch-screen is changed, when touch-screen detects capacitance variations, just can judge the position of the touching touch-screens such as finger, pointer, and carry out the corresponding touching operation of touch position.Have the characteristic that refers to touch-control more due to capacitive touch screen, the operation of hommization can be provided, thereby recently be subject to the favor in market.
Capacitive touch screen generally includes the electrode on both direction, respectively directions X electrode and Y-direction electrode, insulation course between described directions X electrode and Y-direction electrode, all be laid in substrate, for fear of the mutual conduction between electrode block, in described substrate, bridge contact is set, if described electrode block interconnects in one direction, just interconnects by the mode of bridge joint at the above electrode block of another direction so.Although the electrode lay-out of above-mentioned touch-screen also can be used for detecting the position of touch point, because the intersection impedance of adjacent electrode piece is higher, so conduction can be affected, and causes sweep time longer, reduced the signal to noise ratio (S/N ratio) of electrode.
Therefore need to solve above problem for users provide a kind of electrode lay-out of new touch-screen.
Summary of the invention
Technical matters to be solved by this invention is how to provide a kind of impedance low, and sweep time short touch screen electrode layout.
To achieve these goals, the invention provides a kind of electrode lay-out of touch-screen, described electrode comprises some directions X electrodes and some Y-direction electrodes, described directions X electrode and described Y-direction electrode form by some electrode blocks, described directions X electrode block is I-shaped, wherein two is square, middle rectangular, and the volume at two is more broad in the middle, described Y-direction electrode block is groined type, comprise main body and the support body that is extended to surrounding by main body, described Y-direction electrode block is plugged between described directions X electrode block.
Compared with prior art, touch screen electrode layout of the present invention not only can reduce the impedance of existing electrode, improves signal to noise ratio (S/N ratio), can also improve sweep velocity and the newspaper point rate of touch-screen simultaneously.
Description of drawings
Fig. 1 is according to touch screen electrode schematic layout pattern of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Please refer to shown in Figure 1, touch screen electrode layout of the present invention, described electrode comprises some directions X electrodes and some Y-direction electrodes, and the electrode on directions X is followed successively by X1, X2..., and the electrode on Y-direction is followed successively by Y1, Y2..., described directions X electrode is comprised of some electrode blocks 11, the Y-direction electrode is comprised of some electrode blocks 12, and described electrode block 11 is I-shaped, and wherein two is square, middle rectangular, and the volume at two is more broad in the middle; Described electrode block 12 is groined type, comprises main body 121 and the support body 122 that is extended to surrounding by main body, and wherein said support body 122 lays respectively at the position, four of upper and lower, left and right of main body 121.Insulation course between described directions X electrode and Y-direction electrode, all be laid in substrate, for fear of the mutual conduction between electrode block, in described substrate, bridge contact is set, if interconnect at the above electrode block 11 of directions X, just interconnect by the mode of bridge joint at the above electrode block 12 of Y-direction so.
Because the space, two of described electrode block 11 is larger, the support body 122 that extend for the described Y-direction electrode block 12 of pegging graft at the place, intermediate position, be that described Y-direction electrode block 12 is plugged between described directions X electrode block 11, therefore the useful area of described electrode block 11 is larger, thereby the area coverage of activation signal is increased, and can effectively shield noise; Therefore described electrode block 12 can suitably reduce the useful area of this electrode owing to being provided with several support bodies, thereby increases signal to noise ratio (S/N ratio).Two support bodies 122 on described adjacent two electrode blocks, 12 same level lines lay respectively between two of adjacent two described electrode blocks 11, so since, not only can increase the coupling of electric capacity, and can increase signal intensity.
The center at described electrode block 11 two is all hollowed out, and is provided with suspension piece 13 in it, and described suspension piece 13 is rounded, for the shape with the space is identical to the full extent, has so not only overcome the suspension problem of touch-screen, has also strengthened the linearity of touch-screen.Also be provided with suspension piece 14 between two support bodies 122 on the same direction of described electrode block 12, the shape of described suspension piece 14 is identical with the shape of support body 121, and is all rectangular, thereby not only overcome the suspension problem of touch-screen, also strengthened the linearity of touch-screen.
For the ease of calculating, described electrode block 11 and electrode block 12 all are symmetry shape, and the size of all support bodies 122 of electrode block 12 is all identical, so, not only can increase the antijamming capability of capacitive coupling and described electrode, and during the signal transmission, the load delay time is relatively short, thereby sweep velocity is speeded, and newspaper point rate is high, property is made an uproar than greatly.Because described Y-direction electrode block 12 is plugged between described directions X electrode block 11, therefore the coupling of described touch-screen and signal intensity all significantly strengthen.
In the present invention, described suspension piece 13 is identical with the material of touch screen electrode with 14 materials that adopt, and is all ITO, so not only can increase capacitive coupling, strengthen the antijamming capability of described whole electrode layer, and can improve sensitivity, the linearity and the water resistance of electrode layer.
