Claim:
An electronic device comprising: a display element; an infrared light communication device to energize an electroluminescent portion of the display element; and a panel to cover the display element, wherein the panel is arranged to include a single reflective layer comprising a one-sided display, being a half mirror layer and a shading layer, wherein the half mirror layer and the shading layer are formed on the panel, wherein the shading layer has an opening positioned above the display element such that when no electricity is supplied to the display element, a surface of the panel is seen as a substantially continuous uniform color such that the display element is invisible, and when electricity is supplied to the display element, light from the display element is transmitted through the panel so that the display element is visible through the panel, and wherein, above the infrared light communication device, the shading layer filters out visible light while transmitting infrared light to the infrared light communication device.
