Abstract: An exemplary video signal control circuit includes a central processing unit, a signal bus, an address bus, a data bus, a latch module, and a display module. The central processing unit is connected to a latch-enable terminal of the latch module via the signal bus and connected to an input-enable terminal of the latch module via the address bus for controlling the latch module. The central processing unit transmits video signals to the latch module via the data bus and then to the display module if the latch module is latch-enabled and input-enabled. The video signal control circuit transmits the video signal to the display module via the data bus instead of general port I/O pins, and thus the quantity of display units is not restricted by the quantity of the general port I/O pins.
