Zusammenfassung:	一种投影显示器，包括：一照明模块；一光学调制器，用于依照图像数据调制从照明模块入射的光；以及一投影光学系统，用于放大地投影从光学调制器发射的光，其中所述的照明模块包括：至少一个光源；以及一光再生单元，其使得从所述光源发射的具有超出一光可以被所述投影光学系统有效地投影的预定范围的发射角度的光在所述预定范围内传播。 A projection display includes an illumination module, an optical modulator for modulating light incident from the illumination module in response to image data, and a projection optical system for projecting light emitted from the optical modulator on an enlarged scale. The illumination module includes at least one light source, and a light recycling unit which causes light emitted from the light source having an emission angle beyond a predetermined range in which light can be effectively projected by the projection optical system to travel within the predetermined range.
