I have an old LG 19" (4:3) LCD display and I had an idea to connect it to an RPi which should not be a problem but then I had the idea of adding a touch-panel film over the LCD.
Now, I've Googled this for last few days and I cannot find any answers or anyone that has done this.
From what I've seen, there are touch panel films or layers that are pretty raw if you will, no connectors or boards with them and then you have touch panel layers that come with a board and a USB connector as a kit. An example would be: eBay link Editor note: if link rots - the title/search term was: "19.1 inch USB Panel Kit Set - Add Touch Screen Function".
Now the question would be of course if the example Touch Panel (link above) would work with RPi? I'm guessing that the problem would be in drivers for ARM, yes?
