Turning big touchscreen into an iPad...literally

NVM found what I was looking for custom GADZ

So was wondering what the possibility is of taking ...let's say a 40" touchscreen and soldering it's display connection into the iPhones instead.

So unlike mirroring where you still have to use the phone for control, you would be able to touch your new screen and still have the phone as the brains attached to it.

Is it possible?

I like technology just dono how it works so I apologize if this is so impossible it's retarded.

My thinking...

Motherboard, a5 chip for brain----> wires----> to display ---->iPhones touch screen for control.

Then...

Remove wires connecting to iPhone screen----> connect to wires from 3rd party screen -----> BOOM! Giant ipad!!!
