Polymer-Dispersed Liquid Crystal Applied in Active-Matrix Transparent Display

In this paper, we have developed an active-matrix thin-film transistor (TFT) transparent liquid crystal display (LCD) by using polymer dispersed liquid crystal (PDLC) technology. Also, there are some advantages, such as being polyimide-less, polarizer-free, environmental-light only, and so on. In addition, their transmittance of the transparent state is upward 40%, the transmittance of the scattering state is under 3%, and the driving voltage is under 6 V. The transparent display has high transparency, good visibility, and low electric consumption.
