Abstract
A projection system is provided. The projection system includes a light source, a color filter separating light emitted from the light source into colored light, a light-path converter converting a path of the colored light that has passed through the color filter, a lens having a positive refractive power in order to condense the light from the light-path converter, a display device processing the light that has passed through the lens in response to an input signal and forming a color image, and a projection lens unit enlarging and projecting the color image onto a screen.
Claims9
A projection system comprising:
- a light source;
- a color filter separating light emitted from the light source into colored light;
- a light-path converter converting a path of colored light that has passed through the color filter;
- a lens having a positive refractive power in order to condense the light from the light-path converter;
- a display device processing the light that has passed through the lens in response to an input signal and forming a color image;
- and
- a projection lens unit enlarging and projecting the color image onto a screen;
- wherein the lens is arranged on a light path between the light-path converter and the display device so that light incident on the light-path converter and light reflected by the light-path converter pass through the lens;
- and
- wherein the light-path converter is a flat mirror.
