PDLCD (Polymer Dispersed Liquid Crystal Display)
Polymer-dispersed liquid crystal display (PDLCD) is a kind of liquid crystal display.
It has a structure where polymers and liquid crystals are mixed at a certain ratio between polyethylene terephthalate (PET) films with a thin indium tin oxide (ITO) layer.
When inactive, the liquid crystal droplets scatter the light as they permeate the screen, which results in a turbid state.
When a voltage is applied, the liquid crystal droplets align, allowing light to pass through.
This essentially turns the screen transparent.
