在分析激光投影、激光线扫描和激光点扫描三类显示技术的原理、特点及光源需求的基础上，对几种常见的激光显示用光源进行了性能比较，讨论了其关键技术及存在的问题。重点探讨了掺镨(Pr3+)氟化物可见光光纤激光器的研究现状和发展趋势以及其作为激光显示引擎的可行性。由于掺镨氟化物光纤激光器具有宽带可调谐特性，可以通过选择红绿蓝(RGB)三基色的波长使激光显示色域最大化，从而提高激光显示系统的色彩表现力。

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.
