ABSTRACT:
A display screen include a plate, a plurality of microspheres and a mask. The plate has a plurality of holes arranged in a matrix array. Each microsphere has fluorescence behavior and is disposed in one of the holes in the plate. The mask has a plurality of light valves. Each light valve is aligned with the holes of the plate and is optically coupled to one of the microspheres. An ultraviolet light source is optically coupled to the microspheres through the mask. Each light valve is a liquid crystal mechanically coupled to the plate and electrically coupled to a display electronics of a display unit.
