It's designed to minimize RAM footprint by using Sprites to represent objects on the screen. The object model also facilitates partial screen updating which reduces the bandwidth needed to display. This is all handled in C. Python simply manipulates the objects with the ability to synchronize to frame timing.

//| The `displayio` module contains classes to manage display output
|
|
//| including synchronizing with refresh rates and partial updating. It does
|
|
//| not include display initialization commands. It should live in a Python
|
|
//| driver for use when a display is connected to a board. It should also be
|
|
//| built into the board init when the board has the display on it.
