Abstract
PURPOSE:To lower cost and make the device suitable for versatile image display devices for home by subsequently scanning the entire part of the screen with a linear sequential scanning system and applying the digital moving picture display signal having undergone A-D conversion of TV receiving signal and the digital data from processor to a common line memory. CONSTITUTION:The signal from a composite video signal input terminal 6 such as of TV receiver, VTR, etc. is separated to video signal and synchronizing signal in a signal separator circuit 7 and the video signal is applied to a signal processing circuit 8 and the synchronizing signal to a timing control circuit 9. This circuit 8, having been constituted by a sample holding circuit and an A-D converter, sends the digitally converted signal to a changeover circuit 10. On the other hand, the image output signal of the processor 11 is also applied to the circuit 10 and the synchronizing signal from the processor 11 is applied to the circuit 9. With such constittion, the circuit 10 is selectively changed over and these signals are applied to the matrix display panel 16 to which X-Y electrode driving circuits 14, 15 are connected through a line memory 12 and a display signal generating circuit 13.
