Vintage digital display teardown
🕑 Added 2023-10-13 04:46:23 +0000 UTCIt may seem sacrilege to take a vintage display like this apart, but if I take mine apart it means you don't have to take yours apart.
It did go back together again afterwards. In a way it could be fun to make an LED retrofit panel for the back.

I dare say a bank of say eight of these could not be multiplexed, so would require an incredible amount of wiring - and driving - and as you say, power.I wonder if there was a momentary doubling of inputs, to allow for one bulb dimming as the next one warmed up.

The original jumbotron video walls were a matrix of tiny RGB pixel cathode ray tubes.
