• a touch region;
• a border region disposed outside said touch region;
• a signal transmission device disposed in said border region, said signal transmission device comprising at least one heterogeneous conducting line outside said touch region;
• and
• a light transmission pattern disposed in said border region and partially overlapping said signal transmission device along a vertical projection direction;
• wherein said heterogeneous conducting line comprises at least one transparent conducting line overlapping partial said light transmission pattern along said vertical projection direction, said heterogeneous conducting line further comprises at least one opaque conducting line, said transparent conducting lines are electrically connected to said opaque conducting line, and said heterogeneous conducting line does not generate a touch signal by itself.
