Chosen Solution
I am working on a project where I need to connect a smartphone touchscreen display & digitizer assembly unit to PC or another smartphone, as a second screen. How can I connect a phone display to PC?
This is going to require serious hacking. The display connector is proprietary. The signaling protocol is MIPI, however other control signals, power sequence and timing are unknown. You have to find someone who already made this and use his results or get an oscilloscope to probe it out. For touch signal it is entirely impossible. The iphone 6 display has integrated touch sensors, sharing the wiring matrix with the LCD. There is no digital interface to connect to on the touch cable, you have to implement your own capacitance multi-touch driver and sensing circuit, convert and process the raw signals then convert to touch events. To make matters worse, you’ll need to sync the touch scanning with display refreshing, otherwise they will interfere with each other. I don’t think this can be reverse engineered without equipment under a few million dollars. In my opinion just get a cheap iOS device and use some screen sharing app to do it.
