Abstract
The present invention relates to a touchscreen, comprising an electronic visualization structure made of a deposition of layers of: electrically conductive material; on which is deposited electrochromic material; on which is deposited electrolyte material; on which is deposited electrochemically active material, on which is deposited electrically conductive material, wherein the electronic visualization structure is simultaneously an electronic touch detection structure, which touch detection depends on the continuous application of a modulated electrical stimuli; and operates based on variations in the electric capacity of the electronic structure.
