I will explain in more details how this kind of display works.

This display will be later on used for more useful purpose that just display a still image ;)

Depending on the target application (not yet clearly defined!) I will develop either more efficient software if it is intended to be used with a micro-controller, or an IP for FPGA to interface with this display.

Quick update (July 07, 2022):

After some serious optimization and use of SPI (end of the bit-banging for the data transmission!), much more processing power is available to do more useful thing than just display a still image.

Posted a very small video to give an idea of  new possibilities.

I'll come back to describe more in depth operation and optimizations done.

To be continued!
