ABSTRACT:
A triple tube type projection television projects images of blue, green and red projecting tubes onto a screen by lenses disposed in front of the respective projecting tubes, and synthesizes the images by the three projecting tubes on the screen to provide a color image. The projection television comprises a device for offsetting intersection points between the screen and the optical axes of lenses on both sides of a central lens outside from the intersection point between the screen and the optical axis of the central lens; and a device for dislocating the centers of the projecting tubes on both sides outside from the optical axes of the lenses thereof.
