1. A pixel for a video display screen, said pixel comprising:
- a light scattering medium having a non-focusing light emitting surface;
a plurality of light emitting diodes emitting a set of tristimulus colors, each light emitting diode emitting one color from said set of tristimulus colors, said light emitting diodes being embedded in said light scattering medium; and
a light reflecting barrier surrounding the pixel, whereby when two or more pixels form an array, each of the pixels is separated by said light reflecting barrier.
