Large colour gamut display——the new generation of display technique

The emergence of black and white displays in the 1930's, color displays in the fifties, and popular digital displays at the end of the last century correspond to three generations of display technology. Now, the fourth generation, i.e., large color gamut displays, is coming. The “laser display” with lasers as the light source，is the representative of large color gamut displays for the next generation of displays. Its gamut range, more than 2.4 times that of conventional displays, can be as great as 80%. A laser projection display was demonstrated in the Chinese Academy of Sciences for the first time in September 2002, which confirmed the advantages of large color gamut display technology and its commercial potential. Following this, the process of industrial manufacture has begun, and the next generation to come will be the high-fidelity reconstruction of three-dimensional displays.
