Abstract
A touch panel includes a substrate, a transparent conductive layer, and at least two separate electrodes. The transparent conductive layer is formed on a surface of the substrate. The transparent conductive layer includes a carbon nanotube structure comprised of carbon nanotubes, and the carbon nanotubes in the carbon nanotube structure are arranged isotropically, arranged along a same direction, or arranged along different directions. The electrodes are separately located and electrically connected with the transparent conductive layer.
Claims20
A touch panel comprising:
- a substrate;
- a transparent conductive layer comprising a carbon nanotube structure comprised of carbon nanotubes, and the carbon nanotubes in the carbon nanotube structure being arranged isotropically, arranged along a same direction, or arranged along different directions;
