Why?
You could use it as a system monitor display or something. People have been adding small secondary displays to their computers for a long time. Back in the day, we would connect HD44780 character LCDs to the parallel port. There was even a Linux kernel driver for it.
That screen is too small to be practical. Is plugging in a second monitor just too easy or something?
