Optical engine of a projection television

An optical engine of a projection television for enlarging an image and projecting the enlarged image on a screen, the optical engine comprising:

• a Digital Micromirror Device (DMD) for projecting an image;
• a light source disposed at one side of the DMD;
• a lens system for condensing illumination emitted from the light source;
• a first mirror for changing a path of the illumination from the lens system;
• a lens for condensing the illumination from the first mirror;
• a mirror device with a reflection angle adjusted by turning a screw, for reflecting the illumination from the lens onto the DMD;
• a prism disposed on a front surface of the DMD for causing the illumination from the mirror device to be reflected onto the DMD;
• and
• a projection system for enlarging an image and the illumination from the prism and projecting the enlarged image and the illumination onto the screen.

A projection television comprising:

• a screen;
• a body for securing the screen;
• a Digital Micromirror Device (DMD) disposed at a lower part of the body for producing a predetermined image;
• a light source disposed at one side of the DMD;
• a lens system for condensing illumination emitted from the light source;
• a first mirror for changing a path of the illumination from the lens system;
• a lens for condensing the illumination from the first mirror;
• a mirror device with a reflection angle adjusted by turning a screw, for reflecting the illumination from the lens onto the DMD;
• a prism disposed on a front surface of the DMD for causing the illumination from the mirror device to be reflected onto the DMD;
• a projection system for enlarging an image and the illumination from the prism and projecting the enlarged image and the illumination onto the screen;
• and
• a second mirror disposed on the body behind the screen for reflecting an image and the illumination from the projection system.
