Patent ID: 8284471

Claim:
A touch control electrochromic device, comprising: a resistive touch panel unit, comprising: a first transparent conductive substrate; a second conductive substrate, disposed parallel to the first transparent conductive substrate, and the first transparent conductive substrate and the second conductive substrate being coupled to positive and negative terminals of a first power source respectively; and a plurality of spacers, disposed between the first transparent conductive substrate and the second conductive substrate, for preventing the first transparent conductive substrate and the second conductive substrate from being electrically coupled with each other; an electrochromic material, being a pure liquid, filled between the first transparent conductive substrate and the second conductive substrate, and both opposite distal surfaces of the electrochromic material being electrically coupled to an anode and a cathode of a second power source respectively; an insulator, installed at internal peripheries of the first transparent conductive substrate and the second conductive substrate, for isolating the anode and cathode of the second power source from electrically coupling the first transparent conductive substrate and the second conductive substrate, and completely packaging the electrochromic material into the resistive touch panel unit; and a controller, electrically coupled to the resistive touch panel unit, for processing an external touch control signal to drive the second power source to be turned on or off.
