Hi
I have a beautiful 480 x 240 monochrome LCD with touch screen. It's salvaged out of a photocopier and there's no chance of getting datasheets, but reverse engineering the LCD panel seems to be fairly straight forward (mostly line and column drivers). The problem is going to be the touchscreen.
The touch panel overlays the LCD and has a 20 pin flat plastic cable and that's all I know. No driver, no mfg, no part number and I haven't found much, if any info on the net on how to go about interfacing or reverse engineering with the panel. It's not that complex a device, but I don't know where to start.
resistive, capacitive, 4 wire, 5 wire. how to power it...
Any ideas?
