Electrochromic panel and control device
First Claim
1. An electrochromic panel for a control device, comprising:
- a first conduction layer for receiving a positive drive voltage;
a second conduction layer for receiving a negative drive voltage;
an electrolyte layer disposed on the second conduction layer; and
a coloration layer having a pattern and disposed between the electrolyte layer and the first conduction layer, wherein an electron current generated by the negative drive voltage flows from the second conduction layer, the electrolyte layer, the coloration layer to the first conduction layer, such that the coloration layer performs a reduction-oxidation reaction and the pattern of the coloration layer changes from transparent to a non-transparent color;
wherein the electrochromic panel is a user interface of the control device;
wherein the control device comprises a capacitive sense element entirely covering on the electrochromic panel for sensing a position where a user touches the electrochromic panel, wherein an area of the electrochromic panel is equal to an area of the sense element, and a thickness of a protection layer of the electrochromic panel is associated with a thickness of the capacitive sense element to avoid an electromagnetic field generated by the positive and negative drive voltages from interfering with the capacitive sense element.
