I think, that's exactly what it does; it uses FT232 USB to COM chip.
That's the tricky part: The chip can be operated in two different modes.
Normal COM serial I/O and bitbang I/O. Bitbang mode disables the
serial handshake and you can control the single I/O lines
much like a parallel port.
Displays normally use a serial COM interface and just add
a FTDI chip to provide an USB interface.
