Displays in use today are generally large, heavy and consume considerable electrical power. Optical transducers, for example, CRT or plasma devices, convert electrical energy into light, which is usually radiated isotropically so that at normal viewing distances very little reaches the observer's eye. Furthermore, ambient light reflected from the display interferes with the display source and sometimes obscures it completely.
