At the same time, n electron beams (n = 1, 3, 4...) are projected onto a white fluorescent surface, and each of the n partial screens formed by n divisions in the vertical direction is illuminated by the n electron beams. The screen switching period of the cathode ray tube and the original video signal (
Alternatively, using at least one delay means whose unit delay time is above (vertical scanning period) ■, the phase relationship is sequentially delayed by 5, and each time the phase is delayed by 5, red, blue, green,
Alternatively, a video signal processing circuit that outputs a video signal in which red, green, and blue are repeated in a fixed order, and a monochromatic video signal from this video signal processing circuit are switched in units to display each of the above n-divided partial screens. A switching display circuit that modulates the brightness of each electron beam and displays it on each partial screen using a corresponding partial video signal, and a color corresponding to each partial video signal that is displayed on each partial screen of the cathode ray tube. and means for selectively arranging color filters on each of the partial screens.
