Moving Pixels

EPDs have unique characteristics that set them apart from other types of displays, as well as a particular operating mode that can be complex. One of the most challenging aspects is the refresh process, a topic that often raises questions when studying these displays. 

In the second part of this tutorial, we explored the anatomy of an EPD and the role of driver boards. In this third part, we’ll dive into how images are formed on the display, explain what waveforms and LUTs are, and review the different types of refresh.
