摘　　要：在过去三年中,微型显示投影发光二极管(LED)光学引擎的亮度显著地加速增长,在某种程度上超出了许多业内人士的期望。这种快速增长促进了液晶投影电视的出现。综述了应用于投影的LED的进展及相应产品。讨论了基于LED的光引擎的设计,展望了其亮度改进以及新产品研制的前景。The increase in the brightness of microdisplay-projection light-emitting-diode （LED） light engines has significantly accelerated during the past 3 years, to a level beyond many industry expectations. This acceleration has enabled the emergence of LED projection TVs. Here, we review the progress made with LEDs for projection applications and the products being enabled. Design considerations for LED-based light engines are discussed, and an outlook for further brightness improvements and new products is presented.
