摘要： A projection display system includes a full-surround screen, at least one reflective element, and a first projection unit. The full-surround screen defines an accommodation space in the shape of a column. The reflective element is disposed in the accommodation space, and the reflective element has a bottom surface and at least one side surface connected with the bottom surface, the side surface of the reflective element faces the full-surround screen. The first projection unit is used for projecting a first image beam on the side surface of the reflective element, and the side surface of the reflective element reflects the first image beam to allow the first image beam to fall upon the full-surround screen.

摘要： A projector includes a supporting frame, a light source module, and an imaging module. The light source module is fixed with the supporting frame. The light source module is adapted to provide a light beam. The light source module has an optical axis. The optical axis is substantially horizontal. The imaging module is located at an optical path of the light beam. The imaging module has a free end and a connection end opposite to the free end. The free end is adjacent to the light source module. The connection end is connected with the supporting frame. The imaging module is capable of rotating relative to the supporting frame about the optical axis, and therefore a projection location of an emitted light is changed.

摘要： A displaying method of a digital light processing (DLP) projector includes the steps of: providing a light modulation device including a driver printed circuit board and a digital micromirror device (DMD), wherein the DMD includes a plurality of micromirrors each having a first stable state and a second stable state, and a predetermined light incident direction, the DMD is installed on the driver printed circuit board; providing an illumination light beam being incident on the DMD along an operating direction different from the predetermined light incident direction, modulating the illumination light beam to an imaging light beam by the DMD and directing the imaging light beam to a projection lens for projecting an image. A DLP projector made thereby has a relatively lower manufacturing cost.
