The operation principle, characteristics and requirements of laser sources for laser display applications are reviewed, including 2D flat panel spatial light modulator type, scanned linear architecture type and scanned beam type laser projection display. Then, a comprehensive comparison of current light sources for laser display is presented and their key technologies and existing problems is pointed out. Finally, the state of art and future development of Pr3+-doped fluoride glass fiber laser are reviewed, and the potential capability of Pr3+-doped fluoride glass fiber laser as a light source for laser display is discussed. Wideband tunability of Pr3+-doped fluoride glass fiber laser enables optimize the color gamut through careful selection of the RGB wavelenth, hence improves the color reproducibility of the display system.
