PURPOSE:To secure an effective display through a simple constitution by writing the read-out digital signals into the shift register and then reading out the written digital signals in parallel. CONSTITUTION:The timing signal is formed at generator circuit 8 with every second H-period; the control signal thus formed is sent to selector circuit 15; and the video signal given from ratch circuit 6 is written into RAM 16 sequentially and in series. Then the equal-weight bits of the written digital signals are read out in series; the read-out digital signals are written into shift register 17; and the written digital signals are read out in parallel to carry out the display. Thus, an effective display is ensured through a simple constitution. |
