PURPOSE:To perform a color picture display with an electronic beam without a shadow mask and to realize the miniaturization with high image resolution for a color picture display, by providing a CRT containing a display screen which is divided in R. G and B regions in the direction of screen H. CONSTITUTION:The video signal supplied to an input terminal 1 is separated onto three primary color signals R, G and B by a color demodulating circuit 2. For these color signals, the time axis is compressed down to 1/3 by R, G and B signal processing circuits 3R, 3G and 3B respectively to output a compressed time axis during H/3 different from each other in a horizontal period (H period). These signals are added together by an adder 8 and amplified by an amplifier 9 to be fed to a CRT 10 having a screen divided into R, G and B display regions and in the direction of screen H. In such a way, the use of a shadow mask is eliminated and an electric gun which shoots a single beam is available to attain the miniaturization with high image resolution for a color picture display. |
