る。Touch panels used in these devices are made by laminating a transparent conductive film such as ITO on a pair of insulating substrates, etching them to form a predetermined shape, and then placing the transparent conductive films facing each other and attaching the insulating substrates via a spacer. It is pasted together and lies horizontally. Then, by pressing the surface of the insulating substrate with a finger, the circuit is made conductive only at the point where the opposing transparent conductive films are in contact, and a signal is transmitted.
なお、指の触れるタッチ面は、滑らかになっているか、
あるいは油による汚損を防止するために有機バインダー
にμｍオーダーの無機質を分散させた物質を均一に塗布
してざらざらになっている。Also, is the touch surface that your fingers touch smooth?
Alternatively, in order to prevent staining with oil, a substance made by dispersing an inorganic substance on the order of μm in an organic binder is uniformly applied to give the surface a rough texture.
そしてタッチ面が滑らかであってもざらざらになってい
ても、均一な表面になっていると、これに指で触れただ
けでは分割された個々のタッチ面の境界が分らないため
、必ず表示に対応した個々のタッチ面を押圧しなければ
ならない。And whether the touch surface is smooth or rough, if it is a uniform surface, you will not be able to tell the boundaries of the individual touch surfaces just by touching it with your finger, so it will always be displayed. The corresponding individual touch surface must be pressed.
