Can i reuse an phone display? Answered

You must find driver and controller

The people who could help are under contract..

Are you good with conking your noggin against a brick wall for a month... Its just a hard obvious puzzle..

You do need to be machine language programmer..

I personally do not go into that kind of pain without a big reward on the horizon !

I would simply say no as the display without driver board is pretty much useless.
And even if you can get a suitable driver board then I would say a standard 8bit Arduino won't have the power to use a high res display with proper refresh rates.
Just check what is already required to use a 800x600 pixel display with an arduino, especially if you want full color and graphics....

If you can find a driver for it - probably.
