Abstract

PURPOSE:To obtain an excellent picture with a simple constitution, by up-and- down moving a spot of picture on a CRT screen with high frequency, and erasing raster on screen. CONSTITUTION:A signal fF to move a vertical deflection signal VRAMP of a CRT up and down is superimposed and the resulting signal, VRAMP+VF is applied to a vertical deflection circuit. In this case, as an fF signal, a sinusoidal wave or triangle wave is effective. For example, 700 oscillations in 1H=63.56mus, i.e., frequency 11,014MHz is provided and each line is made in-phase. Thus, the raster on screen can be erased.
