For that, you’ll want to follow [elliotmade]’s lead and incorporate fiber optics into your LED matrix. The build starts ... about adding fiber optics to circuit sculptures, though.

Scanning at 80 frames per second he gets a nice, flickerless display. To make both the LED matrix circuit board and the control board, [Joekutz] carved out isolation paths in copper clad boards ...

and a built-in de-ghosting circuit to eliminate LED ghosting artifacts in matrix scanning operations. The device operates over a wide voltage range of 2.7V to 5.5V and an industrial temperature range ...

Tesla was expected to turn on the matrix-LED adaptive headlights in the US long ago. However, it only went halfway by offering curve-tracking adaptive headlights but not individual pixel control.
