Abstract
An optical waveguide () with directional microprisms () and multidirectional light sources ()() are provided for providing overlapping morphing images () and information () on a display () of a touch screen mobile phone or other electronic device (). Microprisms can be patterned in the shape of a particular design, character, icon or other image. The microprisms can include: first microprisms () sensitive to light propagating in only one direction; second microprisms () sensitive to light propagating in a different direction, and a third microprisms () sensitive to light propagation in multiple directions. When light is directed into the waveguide () in a direction to which a portion of the microprisms () are sensitive, a fraction of that light will be directed upward and out of the waveguide () by those microprisms sensitive to light propagated in that direction. Controlling, switching or selectively activating the light sources ()() results in different images () which are displayed and illuminated on the display () of the electronic device ().
