当前主流的液晶显示器(LCD)、等离子显示器(PDP)以及有机发光显示器(OLED)等都存在着色彩重现能力低的问题，无法满足真正的数字高清显示的要求，而激光显示器有着目前主流显示器无法比拟的优点，有可能是未来显示技术的主流。文章详细介绍了激光显示技术的原理、特点、国内外激光显示技术的进展以及存在的问题等，最后指出激光显示器可能引领显示技术的第四次革命。

The current mainstream technologies of the liquid crystal display (LCD), plasma display panels (PDP) and organic light emitting display (OLED) all exist the problem of low color reproduction, which cannot satisfy with the real digital high-definition display requirements. Compared with current mainstream displays, a laser display has the incomparable advantages, which will become the mainstream technology. It detailedly introduces the principle, characteristics of laser display technology, the technology progress of domestic and international laser display, the existing problems and so on. Finally, it points out that the laser display may lead the fourth technological revolution in display.
