| Busbar | Copper strip along the edge that applies the voltage to the ITO layer. |
| Clearing point | Temperature above which the liquid crystal loses its order. |
| Driver | Transformer/inverter that converts mains power into the right AC voltage for the film. |
| EVA / PVB / TPU | Interlayers used to laminate the film between glass. |
| Haze | Percentage of transmitted light that is scattered; a measure of “veil”. |
| ITO | Indium tin oxide, a transparent conductive coating. |
| NCAP | Nematic curvilinear aligned phase – Fergason's original emulsion variant. |
| OCA | Optically clear adhesive – the clear adhesive layer of self-adhesive film. |
| PNLC | Polymer network liquid crystal – a variant with a crystal network instead of droplets. |
| Reverse mode | PDLC that is clear without power and frosted with power. |
| SPD | Suspended particle device – smart glass that tints dark. |
