Abstract
A combined electrochromic/electroluminescent device includes at least one pixel 101-104. Each pixel includes a substrate 107 having an electrically conductive surface 105, and an electrochemically active counter electrode layer 110 disposed on the electrically conductive surface. An electrolyte layer 115 which provides electrolytes is disposed on the counter electrode 110. An electrically conductive layer 125 is disposed on the electrolyte layer 115. An electroactive layer 130 is disposed on the electrically conductive layer 125, the electroactive layer providing both electroluminescence and an electrochromically active working electrode, wherein the electrically conductive layer 125 provides transport of electrolytes therethrough.
