Waveshare has launched the Double Eye LCD module, featuring two 0.71-inch round IPS displays with 160×160 pixels of resolution and 65K color depth, aimed at applications like wearables, robotics, and IoT devices.
The SQFMI Watchy is a fully open-source, hackable ePaper watch based on the ESP32 with a crisp, glare-free 1.54" 200x200 ePaper display which can be programmed using the Arduino IDE and lots of your favourite Arduino/ESP libraries!

Using a sine to binary 16 bit number generator I programmed those numbers into a pair of 2716 eproms to get the 16 bit wide sine number 'lookup table' or in this case 'conversion table'. It works incredibly well and my sine/cosine generator drives a large X/Y C.R.T. P.P.I. (Plan Position Indicator 'think radar'). The display has 64K of pixels and the memory storage has the feature of OR'ing old data with new data that will leave a trail behind any moving object. Best wishes on your project.
