It’s diode rom graphics.
Atari GranTrak 10 used it for graphics, but the then new rom chips for code/data.
The Space Race game. Like a bitmap soldered onto the circuit, as the article points out. This isn't the one I had in mind but it's still an excellent example.
So nice to finally learn the term of art.
