Abstract

A patterned polymer dispersed liquid crystal transparent display using one-time UV exposure is demonstrated. The device is fabricated by exposing the cell with a uniform UV light through a mask with selective attenuation of the UV light. The voltage-transmittance response of the device is different for the corresponding regions. Thus, three different states of total scattering, patterned transparent, and total transparent can be realized by controlling the applied voltages. The proposed device used in shutter mode as smart windows and in projected display mode is demonstrated, which shows great potential for smart windows with customized patterns or logos and has potential application in the field of projected transparent displays.
