Abstract
A projection television includes a video processor to process input video signals, a single CRT to project light according to the processed video signals, a color wheel located in a front of the CRT to filter the light projected from the CRT into predetermined colored light, and a controller to control a rotation of the color wheel according to the input video signals. The projection television uses the color wheel to realize colored light by dividing light produced by the single CRT.
Claims20
