Abstract

A new concept of illumination of the electromagnetic display panels is described using invisible UV light illumination (11, 16) of the display panel to extend the operation of said display panels into low ambient light conditions. Such a solution is possible, if one uses UV fluorescent dyes in the paints or plastic material for the reflective surface (13p) of the selected pixel element instead of the regular reflective ones. The said dyes absorb the invisible near-UV light and upon absorbing it reemit the light in the visible range. The described display panel illumination concept results in excellent contrast, as there is no visible light scattering from the background or protective display panel top covers, which in turn result in haze and glare. Furthermore unlike with the electromagnetic display panels, using built-in light sources imbedded in each pixel element (i.e.: LED,...), the appearance / perception of the displayed characters (shape, geometry) as well as the angular visibility remain unchanged in the high as well as in the low or "dark" ambient light conditions.
