Are you going to use a commercially available customer display or are you going to make your own electronic customer display product?
SKYTRONIC made a customer display product that can communicate through USB. It still requires to finalise the outer casing but for a university project, it is even better to keep it running without the case. The display can be 20x2 or 16x2 according to your requirement. The display interface is connected to USB and we will provide you the USB driver DLL.
