Tinkering with an old lcd

Got an old 22" monitor from work that we were going to throw away. The plastic chassis was falling apart so it wasn’t long for this world.

I gutted it and removed the main driver board for the video display and lcd pane itself, that all appears to work and I think I could power the driver board with 12v supply eliminating the larger power supply board.

Wanted to put it into my desktop behind my glass panel to play gifs or something off a small comptuer like a pi, unfortunately it’s too long.

Thinking I could put it in a wooden frame and make some kind of “art” piece out of it.

Trying to think up some other ways to use it. Maybe stick it in a window have it display weather or some shit.

Magic Mirror comes to mind. But yeah, you could probably write a PowerShell script or some basic .NET/C# to display system stats.

lol I could do something like that with the backlight, I currently have no plans for it but also had no intentions of throwing it away.

I managed to deduce the pinout on the lcd driver board, it requires a 5 volt supply for powering the lcd and a 3.3 volt supply for the logic. I want to figure out a smaller power delivery for it since I don’t need the original backlight and the power supply board it came with is unwieldy.

I probably need about 1.5-2 amps to power everything.

I’m thinking about using a 5 volt power supply that I have which is rated for 5 amps and getting a buck converter to drop it down 3.3 for the logic.

Thoughts? I only know enough about electrics to not kill myself.

That should not be an issue.

Remember that Voltage is forced to the device while Amps are pulled from the device. The device cannot prevent itself from see X volts on the supply line but it can self regulate (pull what it needs) in regards to amps on the supply line.
