Variation circuit unit.
Meanwhile sensing electrode has a structure in which, in this configuration, sensing electrode is generally arranged at both direction (example
Such as, vertical and horizontal direction) on detect apply touch stimulation coordinate.
However, being deposited when forming touch electrode on the substrate in touch panel with convex shape (embossed shape)
In following problem.Firstly, since sensing electrode is protruded with its thickness, so increasing the integral thickness of product.Second, by all
As crackle may frequently occur for the technique of cleaning.
In order to form sensing electrode, after the conductive material of such as ITO is coated in the front surface of substrate, it should go
Except being present in addition to wherein by the conductive material in the region other than forming the region of sensing electrode.Therefore, increase material at
This.Further, since increasing individual technique, so reducing productivity, and fraction defective is increased.
If one in single substrate forms the sensing electrode extended in different directions simultaneously on the surface, can not keep away
Generate intersection region with exempting from, and sensing electrode should be electrically insulated from each other in intersection region.Therefore, technique becomes complicated.
