Hi all,

I am in search of a small cost effective transparent LCD screen for a prototype board or for connecting straight to my PC (preferable).

I see that transparent screens are more popular in the Transparent OLED technology, however, those work more in the additive light model while I'm looking more for a light subtractive device, meaning that I don't want to light up a transparent pixel, but rather turn that transparent pixel less transparent, or to the limit opaque.

From what I read, this is how LCD screens function. You apply current to a pixel, and that pixel turns opaque. However, everything I find out there is an actual screen. I'm looking for a transparent version.

There seems to be a few solutions our there:
- take apart a monitor and use the screen--> does this actually work? anybody tried? any instructions on how to do this?
- part available online? I have not found anything on DigiKey or Mouser, any other sources?


Any information would be greatly appreciated! Thank you all

Thanks for the reply.

By small, I mean something in the 2 x 3" range, more about lower cost than actual size however.

Cost would be something affordable for prototyping and proof of concept, <50$ would be the target.

The difference with these TOLED is that those are by default transparent and then you would make pixels shine brighter. What I am looking for is for the pixel to turn opaque, so it'd be more of the old LCD technology
