This display is the modern 16x2 display for hardware hackers: cheap and versatile.

One of my favorite hacks is running this display over HDMI [0].

Note that it’s possible to refresh it at higher rates by using partial refreshes. Or even higher to 150 fps [1].

I switched from 16x2 to SSD1306 because the latter runs on 3.3 V, and is thus more friendly to battery power.

Not really, the ssd1306 has quite short lifespan

I used one to display network statistic on my homelab server, after a year, many pixels is supper dim. They are clearly burned in. I think the display is not meant to be used for long time, but rather for short time. Meanwhile i have seen 16x2 lcd being used for over decade without issue

Potentially the pixels are being driven stronger than spec'ed (or the spec is too agressive also possible), OLEDs typically have that issue but can last longer with a lower max power.
