I have here a broken photoframe with an intact 7in LCD, LG Philips - LB070WV1 (TD)(03). Its an excellent high contrast display so it occurred to me that it might be useful for one of my projects on the Raspberry Pi. Having had a look at the hardware however, the ribbon cable that attaches to the main board in the photo frame is wider and has differently spaced connectors so is not a direct fit for the interface on the Pi. It is, however a matching fit for the ribbon connector on the controller board to the rear of the 3.5in Pi display that I have and the connector spacing is identical.
I have yet to install the driver for the 3.5in LCD display and test it, but I was wondering, once I get the 3.5in display working, whether connecting the 7in display to this board is this likely to work? If it does, then is it possible to obtain the controller boards separately?
