Abstract:
1. A substrate of a touch panel in manufacturing process, an upper sensing electrode layer, an upper signal conducting layer, and an upper protection layer being formed upon an upper surface of the substrate in order; a lower sensing electrode layer, a lower signal conducting layer, and a lower protection layer being formed to a lower surface of the substrate in order; X axis sensing traces and Y axis sensing traces being formed to the upper and lower sensing electrode layers respectively; the signal conducting wires of the signal conducting layers being connected to the sensing electrode layers; the upper protection layers being formed above the upper sensing electrode layers and the upper signal conducting layer so as to protect the layers from being damaged, and the lower protection layers being formed above the sensing electrode layers and the signal conducting layer so as to protect the layers from being damaged; the substrate comprises: a plurality of identical positioning indications which cause that coordinates on the upper or lower surfaces of the substrate are identical; the identical positioning indications being selected from one of a plurality of holes formed on an area out of the touch sensing area of the touch panel; a plurality of gaps formed at edges of the substrate and vertical to an upper or a lower main surface of the substrate; positioning indications being formed by engraving of laser; and a pair of positioning indications on the upper or lower main surface of the substrate being positioned along a same line vertical to the upper or lower main surface of the substrate; and a combination of above mentioned ways; and after manufacturing process, the positioning indications can be removed or not removed.
