I just bought one of these:
It’s a single 64x64 panel with probably some FPGA on top.
The thing is that it has 0 visible flickering on my camera, it’s just perfect, you can’t tell it’s a scan matrix.
My understanding is that it’s only possible with a very high refresh rate, but I remember @Louis saying that if you refresh too fast, the panel is dimmer. From my tests, it doesn’t really seem that dim.
So, I’m a bit confused, how did they get that panel bright enough while having a very fast refresh rate?
As a related question, what’s the fastest refresh rate that has been achieved for 64x64 with teensy 3.6 and ESP32?
