Abstract
Display device in which light is generated in patterned areas of electroluminescent material (via UV radiation, LED-driving or optical pumping), which light leaves the areas by waveguiding along edges of said area, where it is directed to the viewer by light-scattering or reflecting elements.
Claims12
A display device comprising a first substrate with pixels, provided with a patterned layer of luminescent material, and means for exciting the luminescent material during use, characterized in that at least an area of the layer of luminescent material is situated between a layer absorbing light at the viewer's side of the display device and a dielectric layer, and the patterned layer of luminescent material is provided with light-reflecting or light-scattering means at least along a part of its edge, wherein a portion of light exiting directly from the edge is reflected in the direction of a viewer.
