“…Kim et al developed PDLC-based large-area flexible smart windows using roll-to-roll slot die coating with Ag nanowire electrodes [22] . Besides, PDLC used to define the projected image shape in a see-through projected display device was proposed by Su et al [23] . Last but not least, Wang's group proposed an integral imaging-based 2D/3D convertible display system by using holographic optical elements and PDLC film [24] .…”

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.

Liquid crystal (LC)-based research and its technological output vary from daily-use personal electronics and flat panels to switchable optical devices such as sensors. Optical and dielectric anisotropy is a key attribute of LCs, imparting functionality and broadening the scope of smart film systems to such products. Among LC smart films, the polymer dispersed liquid crystal (PDLC) smart film depicts an electro-optical (EO) composite sandwiched by transparent conductive oxide electrode-coated polyethylene terephthalate (PET) films. LC orientation and optical transparency in the composite are readily tuned by altering the electric field. The competitiveness of such PDLC devices reflects its favorable response time, energy conservation potential, and manufacturing convenience, all attributes that are readily endorsed by smart home appliances and areas of architecture and the automotive industry. In response to unrelenting market demands, sustainable, energy-efficient, and “greener” PDLC variants have appeared. Particularly worthy of mention are systems featuring transparency at zero field (reverse-mode). Others boast very high energy efficiencies (%80). In this chapter, the science and technology of PDLC, reverse-mode PDLC, and related LC smart films will be reviewed with a highlight on fabrication methods and operating principles. Market potential and research prospects compared to non-LC smart film technologies will also be touched upon.
