8 sourcesI used the same approach to play music from a .wav via pulse density modulation -

In Leaking Secrets from Air-Gap Computers by Spelling Radio Signals from RAM (2024)Based on a repo I found that twiddled the memory bus, I transmitted audio from a wav file via Pulse Density Modulation - https://github.com/anfractuosity/musicplayer
In Raspberry Pi Pico as AM Radio TransmitterI got my laptop to play Taylor Swift on the AM band - https://www.youtube.com/watch?v=KH9yb1qFKDY by twiddling the memory bus (sounds a bit iffy ;)
Code: https://github.com/anfractuosity/musicplayer
Based on the work of https://github.com/fulldecent/system-bus-radio
In The Taylorator – All Your Frequencies Are Belong to UsGood question, I used PDM to play a song with vocals ( https://github.com/anfractuosity/musicplayer ) by twiddling the memory bus and picking up via an AM radio. So wouldn't be surprised if it was possible with an LCD.
In Tempest LCD: Playing songs from your LCD monitor with a radioI wrote a program based on that:
https://github.com/anfractuosity/musicplayer
Which plays .wav files (example with Taylor Swift) to a nearby radio

In System Bus Radio: Transmits AM radio on computers without transmitting hardwareA few of mine:
https://www.anfractuosity.com/projects/painting-a-christmas-... - 'painting' the LEDs on my christmas tree.
https://www.anfractuosity.com/projects/optical-magnetic-stri... - optically decoding data from magnetic stripe cards.
https://www.anfractuosity.com/projects/zymeter-simple/ - a rather unsuccessful attempt at measuring specific gravity.
https://github.com/anfractuosity/musicplayer - playing .wav files via RF emissions from a laptop.
