DIY Project Snowblind (LCD dissasembly)

[MrSuper]

Hi, so I had a spare monitor and I wanted to do a custom DIY Project Snowblind (Samsung SyncMaster 191T)

I have taken it apart up to the LCD screen and the main board. However, the LCD is not at all transparent, and I cannot see anything displaying on it once plugged in correctly (without backlight).

If you've taken off the backlight and light diffusing layers all you will be left is the LCD, it require a lot of lighting for you to be able to see through the LCD once it's turned on. The inside of the Snowblind case was blindingly bright with the number of LED strips required to make it transparent looking.

So you're saying the part you can see in the picture about, is going to be transparent once enough lighting it put behind it? Also, should I be looking at it from the shiny part of the matt part?

Turn the display on and run something on it right now the display is off and will only show black, that will also determine what side the panel should be mounted since it will be backwards if you mount ti the wrong way.

Alright, after putting in two sets of LED strips inside my case, and putting the LCD into place, I can barely see the glare from each individual LED. No components are visible. I'm thinking there must be some kind of layer still on the LCD that I missed. Is there a chance that is the issue?

 

EDIT: and also, will I need the monitor PSU to power the screen or can I just somehow connect wires to some Molex cables on my PC PSU?

Can someone link a good guide for this kind of thing?

Power the screen first if it's off the pixels will just show black and not easily let light through. As for powering the screen directly off the PSU you will need to find the voltage required for the screen's control board, if it's standard 12V it would not be too hard to fabricate an adapter.

So, it worked. Before when I thought it was on, it wasn't. I needed to plug in the buttons to the board and press the Power button. But it was still too dark. So I went ahead and removed the polarizing filter following a YT video. And I made my LCD useless because I didn't realise removing the polarizing filter would make it so that nothing will show.

Going to have to get a new one.

It may have just been the panel you've gotten where the LCD display itself was rather dark but in general though if your displaying a white image on the screen it should go basically transparent to see through, similar to a tinted window with the white LED's in the case.

Alot of light will be required, I took apart a cracked 24" led monitor a while ago, and when driven off the correct voltage, the LED backlight was enough to light our medium sized living room. I couldn't look straight at it.
