Abstract:
1. A touch panel comprising: a first electrode plate comprising a first transparent conductive layer, a first substrate, and a first glue layer securing the first transparent conductive layer to the first substrate, wherein the first transparent conductive layer is a carbon nanotube structure having a plurality of carbon nanotubes substantially arranged along a first axis, a plurality of clearances is defined between the plurality of carbon nanotubes, and a first portion of the first glue layer infiltrates into the clearances; a second electrode plate comprising a second transparent conductive layer opposite to and spaced from the first transparent conductive layer, a second substrate, and a second glue layer securing the second transparent conductive layer to the second substrate, wherein the second transparent conductive layer is a carbon nanotube structure having a plurality of carbon nanotubes substantially arranged along a second axis; a plurality of clearances is defined between the carbon nanotubes of the second transparent conductive layer, and a first portion of the second glue layer infiltrates into the clearances of the second transparent conductive layer; and a transparent insulator located between and contacting the first transparent conductive layer and the second transparent conductive layer, the transparent insulator having a refractive index larger than 1.0, wherein the transparent insulator is a continuous layer in a solid state, a first portion of the transparent insulator infiltrates into the clearances and contacts with the first portion of the first glue layer, a first portion of the transparent insulator infiltrates into the clearances of the second transparent conductive layer and contacts with the first portion of the second glue layer, a connection through the transparent insulator is formed between the first transparent conductive layer and the second transparent conductive layer when the transparent insulator is deformed by pressure, and the transparent insulator is restored to its former condition when the pressure ceases.
