Abstract
The invention discloses a single-deck capacitance electrode layout structure which comprises a substrate. A plurality of X electrodes and a plurality of Y electrodes are distributed on the substrate, wherein the X electrodes and the Y electrodes are parallel to one another and are arranged in the same direction, each X electrode comprises a main body and a plurality of branch bodies, each Y electrode comprises a main body and a plurality of branch bodies, each branch body extends from one side of the main body and then revolves back to the main body, and branch bodies of adjacent X electrode and Y electrode are arranged opposite to one another and are matched with one another. By means of the single-deck capacitance electrode layout structure, not only is a multi-finger touch function achieved, but also the cost of a touch screen is lowered. Meanwhile, coupling signals are added among electrodes, therefore, the signal strength of the touch screen is strong, the linearity of the touch screen is high, scanning speed is improved obviously, and at the same time signal resolution in a suspended state is improved.
Description
Technical field
The present invention relates to capacitive electrode layout structure field, particularly relate to a kind of capacitive electrode layout structure of individual layer.
Background technology
Traditional capacitive touch screen generally includes the electrode on the both direction, be respectively directions X electrode and Y direction electrode, between described directions X electrode and the Y direction electrode is insulation course, all be laid in the substrate, for fear of the mutual conduction between the electrode block, in described substrate, bridge contact is set,, just interconnects at the above electrode block of another direction so by the mode of bridge joint if described electrode block interconnects in one direction.Though said method has been realized the action that detecting touches, this employing double-layer capacitance formula electrode lay-out structure, not only complex process, and bridge joint place damages easily, and the product yield is low, causes cost to raise.In order to overcome above-mentioned shortcoming, part manufacturer is arranged on double-layer conductive material (as ITO) both sides of glass substrate, so, technology is simple really a lot, and improved the product yield, but still adopting the wire structures of double-deck ITO, the cost of ITO own is just higher, add structure of two layers, the thickness that forms touch-screen has thus also just been increased.If can overcome the limitation that the two-layer electrode structure is brought, so no matter be to consider that from the cost or the structure of touch-screen the single-layer electrodes structure all has more advantages.
In addition, find through a large amount of tests, there be defectives such as referring to touch detection instability, power supply noise disturb greatly, setting-out poor effect for traditional electrode structure such as diamond structure more, therefore need solve the problems referred to above for users provide a kind of novel individual layer capacitive electrode layout structure.
Summary of the invention
The technical matters that the present invention mainly solves provides the strong individual layer capacitive electrode layout structure of a kind of capacitive coupling degree.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of individual layer capacitive electrode layout structure is provided, comprise a substrate, be laid with some X electrode and Y electrodes that are arranged in parallel along a direction on the described substrate, described X electrode and Y electrode include a main body and some support bodies, described support body extends and circles round to described main body from a side of described main body, adjacent described X electrode and the support body of Y electrode is provided with in opposite directions and coupling mutually.
The invention has the beneficial effects as follows: the present invention utilizes individual layer capacitive electrode structure not only to realize the function of many fingers touch-control, and reduced the cost of touch-screen, by increasing the coupled signal between the electrode, make the signal intensity of touch-screen stronger, the linearity is higher, sweep velocity also significantly improves, and has also improved the signal resolution under suspended state simultaneously.
