This PCB is a small screen, a 5" screen/display .. If I were to turn it over you'd see a display
What is meant to be plugged into the USB connector labelled "Touch" on this screen?
(Excuse the fact that apparently it's on a fleece material, and not a good idea to put a PCB on a fleece).
If you connect this usb to a computer, it would allow touch controls.
Eg: This port is used to comminuciate touch capabilities of the screen. Usuaully this screen is an embedded screen on a device, and this wire is not shown to the user, but it connects internally to the pc so that it has an additional mouse so to speak.

barlop: "so that connector would go to the computer and cause the device's panel to be both screen and touchpad?"
lpchip "yes , that's basically how it works."
