Abstract

A color projecting apparatus includes a first LCD panel, a second LCD panel, and a third LCD panel, which respectively receive a first light ray of a first light color emitting from a first light source, a second light ray of a second light color emitting from a second light source, and a third light ray of a third light color emitting from a third light source and receive corresponding images respectively of the first light color, the second light color and the third light color from an image source to respectively transmit out images of the light color, the second light color and the third light color corresponding thereto. The image of the first light color is reflected by a first reflector. A first mixed light ray is formed by reflecting the second light ray by a second confluence splitter and making the first light ray reflected by the first reflector be transmitted. A second mixed light ray of a final image is formed by reflecting the third light ray by a third confluence splitter and making the first mixed light ray be transmitted and is projected, after necessary processing by a lens module, to a screen to form a projection image. The LCD panels may be changed into a selector switch to generate alternatively-arranged pulse waves with different light colors. The projection image required is formed by means of an imaging IC.
