Actually this screen has been lying on my desk for a long time, I got it in Hong Kong. Actually it is exactly the screen used in the Hong Kong Metro. I got two of them, one has some LEDs knocked off, the other is intact. The screen is self-scanned, means that it can be controlled by slower MCUs without introducing lot of flickering.
Here is it. Previous post: https://sites.psu.edu/wenting/2015/12/09/revisiting-buzzer-demo-3-voice-aliez-chiptune/
Now I have done the hardware part. I also 3d-printed a case for it.
I decided to use my LCDs to build something. Maybe a RPN calculator?
