I have a three-color, 5.3 inch display. It takes around 25 seconds for a full screen update. But with some waveform hacking (courtesy of the seller, “GoodDisplay”) and some creative use of the controller chip interface spec which differed slightly from the display interface spec… I’ve managed to get rapid, partial black and white updates working. So you can create a ‘background’ out of three colours, then so long as you update rectangles that only contain black/white pixels, you can do a sub-second update. Mine is a display that sits inside a PC, it shows the time, CPU and GPU temperatures, updated once a minute, and has a black/red fractal pattern that only updates on a full refresh which I scheduled for every 15 minutes. Something similar may work with yours? |
