ABSTRACT:
An electro-optic display device uses a transparent luminescent panel to reflect and diffuse ambient light, or light from the luminescent panel to a display cell to enable a user to read the display cell. The luminescent panel includes a first transparent electrode arranged between the display cell and a luminescent film. The panel further includes an activation electrode on the opposite side of the film from the first electrode. The activation electrode acts as a reflector - diffuser to reflect and diffuse light received through the other parts of the panel or from the luminescent film itself back to the display cell.
