Abstract
The invention provides a single-layer multi-point touch screen comprising a substrate. The substrate is provided with a plurality of sensing electrodes distributed in parallel along a first direction. Each sensing electrode comprises a plurality of hollow parts, and each hollow part is internally provided with a drive electrode block separate from the hollow part. The drive electrode blocks in the same order on each sensing electrode are short-connected to from a drive electrode channel. When the sensing electrodes serve as drive electrodes, original drive electrode blocks serve as sensing electrodes. The single-layer multi-point touch screen has the advantages that a multi-touch function is achieved, cost of the touch screen is lowered, and the increase in coupling signals among the electrodes leads to increase in intensity of coupling signals of the touch screen, increase in touch linear and evident increase in scanning speed.
Description
Technical field:
The present invention relates to a kind of ITO wire structures of individual layer multi-point touch panel.
Background technology:
Recently, along with the development of touch technology, the requirement of people to the touch screen that it uses is more and more higher, and not only appearance requirement is more magnificent, and its price is also tending towards reducing.In order to reduce costs, increasing design corporation have employed individual layer ITO to replace the touch screen of traditional two-layer ITO composition, because the price of ITO own is more expensive, and the complex process two-layer ITO is laid on touch screen, so utilize the touch screen of individual layer ITO to be not only that price has more advantage, its comparatively simple processing step has also become a megatrend of touch screen future development.
Present stage, individual layer touch screen adopts two kinds of pattern self-capacitances and mutual capacitance, the Butut of the ITO that self-capacitance adopts is generally that horizontal triangle or perpendicular triangle are capable, for triangle, owing to being form one group of electrode component by two symmetrical triangles not lay on the ito layer, so just have certain restriction to the size of described touch screen, along with successively decreasing gradually of triangular angles, the position of touch object as finger touching just can not be differentiated fast, thus can not accurately judge the particular location coordinate of touch point.The ITO Butut that mutual capacitance adopts has bridging type or caterpillar.For bridging shape, need OC to insulate, making needs four MASK, cost intensive.And for caterpillar shape, adopting pure ITO Butut, gold-tinted only needs a MASK or adopts laser dry etching to do, and cost reduces by four one-tenth, and can develop Rimless screen, produces Rimless screen module.
In order to reduce complex process degree, therefore need for users provide the wire structures of a kind of new individual layer ITO.
Summary of the invention
The technical matters that in fact the present invention will solve is to provide and a kind ofly realizes the strong ITO wire structures of capacitive coupling degree.
Technique effect of the present invention is: utilize single layer of conductive material not only to realize the function referring to touch more, and reduce the cost of touch-screen, by increasing the coupled signal between electrode, the coupled signal strength of touch-screen is increased, make the touch linearity higher, sweep velocity also significantly improves.
Technical scheme of the present invention is achieved in that in a kind of individual layer capacitance touch screen, comprises a substrate, and described substrate is laid with some induction electrodes arranged in parallel along first direction, and each induction electrode has multiple hollow bulb; Each hollow bulb is provided with a drive electrode block, described drive electrode block and described hollow bulb from, the drive electrode block phase short circuit that on each induction electrode, order is identical forms a drive electrode passage, and described induction electrode can be changed into drive electrode, and former drive electrode block then becomes induction electrode.
The each hollow bulb of induction electrode of the present invention all has a breach of drawing for drive electrode block lead-in wire, and the breach in adjacent hollow portion is separately positioned on the relative both sides of described induction electrode.
Drive electrode block of the present invention and described hollow bulb distance range are 200 ~ 300um.
Drive electrode block of the present invention is hexagon or fork type.
First direction of the present invention is vertical direction.
On substrate of the present invention, base or bottom binding have flexible circuit board, and described drive electrode block cabling guides base or bottom binding on told substrate nearby into the respective channel of flexible circuit board.
Individual layer multiple spot ITO wire structures of the present invention, ITO pattern is wavy arrangement, and angle of bend is between vertical direction left avertence 10 ° ~ 20 °, reduces LCD and interferes the end shadow produced, decrease this procedure of shadow that disappears simultaneously, reduce cost.
