Electrochromic touchscreen device

An electrochromic (EC) touchscreen device comprising:

• first and second transparent substrates positioned opposite each other;
• first and second transparent flexible electrodes positioned opposite each other and between the first and second substrates, the first electrode positioned to be at least partially covered by the first substrate, and the second electrode positioned to be at least partially covered by the second substrate;
• a polymer-based electrochromic layer positioned between the first and second electrodes, the electrochromic layer in electrical communication with the first and second electrodes;
• and
• a controller configured to:
• provide a first control signal to the first and second electrodes to supply power to the electrochromic layer;
• and
• provide a second control signal to the first and second electrodes to detect a user touch,
• wherein the first control signal is active and the second control signal is not active over a first duration of time, and wherein the second control signal is active and the first control signal is not active during a second duration of time that does not overlap with the first duration of time.
