Large screen laser projection display and laser telvision

Laser projection, the next generation of full-color display technology, has many advantages over traditional display technologies due to the laser's large color gamut, low power consumption and potentially long lifetime. Its historical development and present state-of-the-art at home and abroad are reviewed. Two systems, one based on a diode laser pump and another on liquid-crystal-on-silicon, are described. Laser and color management are discussed, and the advantages of laser projection display summarized. To conclude, the industrialization and overall market prospects of laser display technology are evaluated.
