Connecting large TFT/OLED touchscreens to MCUs

I noticed in many cases a large screen is needed for all kind of things in Arduino or mcu projects.
Many people have successfully managed to connect and control large panels f.ex. with STM32 mcu.
I am trying to find out a way to connect faster mcu to larger lcd/retina panel as they are around $15-25
now and prices are falling.

Wonder if anyone tried that. Thanks and cheers! :wink:
