Official Pi 7 inch Touchscreen

Hi,
I have a official raspberry pi 7 inch touchscreen laying around and i was wondering if there is any way of using it with an Arduino mega for a project.
All options are open and i'm open to ideas with this. I know i could use a raspberry pi and interface the pi with the arduino but i already have a full working interface for a smaller 2.5 inch screen and want to know if the larger screen can be used with the Arduino in any way

Any help would be great!
