Touch panel
A touch panel may include a substrate, a touch unit region and a covering layer. The touch unit region includes first electrode and a second electrode isolated from the first electrode. The covering layer covers at least one of the first electrode and the second electrode and has a touch surface. A distance between the touch surface and the first electrode or the second electrode ranges between 0.01 micrometers and 100 micrometers. A mutual capacitance value between the first electrode and the second electrode ranges between 0.1 pF and 10 pF when a touch has not occurred yet.
