Trying to find a way to make a true pixel screen Using UVs to animate the shapes on the screen would be hard and tedious so i want to use geometry to impact which dots light up

the compositor won't really help as it pixelates where the camera is facing rather than where the mesh is facing

when i used animation nodes the matrix wouldn't parent to my plane, and the rotation only affected the induvidual bounds of each sphere (which is what i used to make the leds)

something like this effect: https://blenderartists.org/t/animatable-pixel-matrix-display/1126033/11

Can i make a mesh light up when something touches it?

^ it's better explained in this new one i made
I still think UV map could be quite handy:




Scale the UV maps into individual pixels by scaling them to 0
Connect the UV map to Image texture
Use Mapping node to animate it
