I bought this 7″ LCD screen from Frys on clearance for only $5. It has a weird connector to connect to the companies DVD player or something. I rewire it to work on Composite input (RCA plugs). I also make it Touchscreen for the computer using a USB transcriber
Everything may work as planned, but this TV is low quality video (Composite quality).
Its Great as a media player remote. I am sure it can be used for lots of things.
I think it would have been a lot easier to just buy one of these: HDMI Display 7 Inch 1024X600 LCD with Touch Screen (Amazon)
