Sounds like a 'fun' project.
If you're considering the 100mm (4 inch) displays, they usually require a higher voltage so source drivers are different. The circuit below should work. Full brightness with PWM brightness control. Add power brick, regulators, and switches if necessary. Battery backup?
If this is a "one off" project you might be able to draft one of us PIC guys to help you with the program and to burn a chip for you.
