- TL;DR Summary
- Analyzing a commercial smart glass product that switches from semi-transparent (OFF) to fully opaque (ON) with 12V input. Trying to identify if it uses PNLC, Guest-Host LCD, or another tech. It has a black film layer on one side, a transparent layer, and a multi-pin FFC cable. Goal: replicate or improve it with higher transparency and opacity at low cost. Looking for expert input
Hello everybody
I discovered this cover a while ago and I am trying to understand its work and the last thing I found is that it might be PNLC ( Polymer Network Liquid Crystal ) and this is what I often think
Or it is GHLC ( guest-host liquid crystal ) and this is not likely because I think it is more expensive than the PNL
The way it works is when the current is connected to it, it becomes opaque black, and when the current is cut, it returns transparent (relatively)
Also there are two pictures and I am trying to turn it at a 90 degree angle and it turns out that there is a vision
But when you turn it in the other direction, it becomes invisible.
From the pictures, it is clear that there is a small fragile bottle covered with a layer of one side in black, and this is what prompted me to think, is this bottle of the ITO type? Or just a regular PNLC bottle and it was painted from one side
You can notice scattered squares of glass slightly protruding from the top and have been marked in red
I will upload some pictures to clarify the idea for you
Maybe you know what the materials are.
And if you have an idea for something similar and less expensive hello everyone
Thanks for all your efforts
