Abstract
A projection television receiver for embodying a high definition and high quality projection television receiver by processing an image of an image source. A red, a green and a blue image are formed and emitted into a red, a green and a blue colors at a cathode ray tube. The emitted red, green and blue images are received and gathered for reiterating the red, the green and the blue images at a mirror unit. The reiterated red, green and blue images unit are displayed onto a screen by enlarging and projecting the images through a lens assembly.
Claims11
A projection television receiver, comprising:
- a cathode ray tube which forms and emits a red, a green and a blue image separately according to each color;
- a mirror unit which receives and gathers said emitted red, green and blue images for reflecting the red, green and blue images, wherein said mirror unit comprises a first mirror for receiving and reflecting a first one of said red, green and blue images emitted from said cathode ray tube, a second mirror for receiving and reflecting a second one of said red, green and blue images emitted from said cathode ray tube, and a third mirror for receiving and reflecting a third one of said red, green and blue images emitted from said cathode ray tube and said first and second ones of said red, green and blue images reflected from said first and second mirrors;
- and
- a lens assembly which enlarges and projects the reflected image from said mirror unit for displaying the images onto a screen, wherein a sectional shape of a panel of said cathode ray tube corresponding to said red, green and blue images is biconvex, respectively and fluorescent material corresponding to a red, a green and a blue colors is spread on a convex portion of an inner surface of said panel.
