present stage, the Butut of the ITO that is adopted on the individual layer touch screen generally is triangle or rectangle.For triangle; Owing to be to form one group of electrode group through two symmetrical triangular shapes to be laid in respectively on the ITO layer; So the size to said touch screen just has certain restriction; Along with successively decreasing gradually of triangular angles, the position of touch object such as finger touches just can not be differentiated fast, thereby can accurately not judge the particular location coordinate of touch point.And for rectangle; Be to be laid on the ITO layer by several rectangular-shaped electrode blocks; Because separate each lead of drawing of each electrode block is connected on the respective scanned pin of chip on the touch screen, so finger can be judged its particular location accurately at any one, but because the restriction of scanning pin in the chip on the touch screen; Designers must take all factors into consideration the size of Touch Screen, just can determine the size of rectangle.And for the giant-screen touch screen, under the certain situation of scanning pin, Touch Screen is big more, for rectangular configuration also should be big more.So, if the area of rectangle is during greater than the area of normal finger touch points, when finger moves line on touch screen, the situation that just possibly occur breaking.For fear of above-mentioned situation, we are set to waveform at the two rectangular-shaped relative parts of electrode block, hope to overcome the problems referred to above with this, but in the practical application, if rectangular-shaped length or width are excessive, still can cause the broken string problem.So only cause the problems referred to above, when an important reasons just was that finger moves on electrode block, area did not change, and caused that the induction amount does not change, the final situation that broken string occurs.
in order to solve the above-mentioned broken string problem that possibly occur, and therefore need solve above problem for users provide the wire structures of a kind of new individual layer ITO.
Summary of the invention
The actual technical matters to be solved of
the present invention is how a kind of wire structures of avoiding when line, occurring the individual layer ITO of broken string problem is provided.
are in order to realize above-mentioned purpose of the present invention; The invention provides the wire structures of a kind of individual layer ITO; Said individual layer ITO is provided with several electrode blocks; Form some stringers and file, the area of any adjacent two electrode blocks is alternation trend with the slip of touch object on said stringer or the file.
The wire structures of
individual layer ITO of the present invention; Not only simple; And cause the variation of influence value through the continuous variation of induction area on the electrode block, finally be implemented in the purpose that can detect the sliding trace of finger when individual layer ITO goes up the line of any position accurately.
