Abstract

PURPOSE:To enable PPI display with high luminance and without flicker, by providing the video memory for one screen's share and reading out the content of memory repetitively in high speed while altering it with input signal. CONSTITUTION:The video signal is in digital conversion with the resolution in which a given intermediate tone can be reproduced and it is written in the address of the video memory 7 selected with the memory control circuit which can be controlled with the trigger and directional signal. The readout is made repetitively in high speed independently of the write-in timing and the data read out from the video memory 7 is converted into analog video signal with the D/A converter 9 and fed to the Braun tube 2 via the amplifier 5.
