Laser display technology

The promise of producing a cathode-ray-tube type of display with essentially unlimited screen size accounts for much of the current interest in laser displays. The first display that used a laser light source to generate a television image was operated in late 1964. Since that time, a number of experimental laser display systems have been demonstrated, including versions capable of reproducing color television images and displaying computer-generated information. Adequate light modulation and scanning techniques are presently available, but the design of broadly applicable equipment still awaits the development of more efficient multicolor lasers.
