“…In practice, typical reflectance values are lower than 40%. There is substantial work underway in a variety of emerging technologies to develop alternate approaches that improve the overall reflectance [7,8,9]. While all of these approaches have the potential to yield a higher maximum reflectance than conventional liquid crystal displays, the TIR-based approach discussed here shares this capability and has additional unique advantages.…”

This paper begins by "re-introducing" the phenomenon of total internal reflection and the associated critical angle, including a careful discussion of the extent to which the "total" in TIR is truly total, and the "critical" in critical angle is truly critical. Although in one sense these points are largely of theoretical interest, they also have an applied aspect in relation to controlling TIR. From this perspective, two practical applications of TIR are discussed. The first involves illuminating engineering applications with prism light guides, and the second concerns electronic image displays employing frustrated TIR. In both cases the unique attributes of TIR play a key role in the efficiency and practicality of these applications.

“…Unlike other LC-based devices, PDLCbased devices are easily implemented as LC alignment layers and polarizers are not required. This electrically switchable scattering behavior of the PDLC structure is promising for a number of electro-optical applications such as projection displays [8], flexible displays [9], holographic optical elements [10], and smart windows [11]. The phase separation for PDLCs preparation can be induced by ultraviolet (UV) light [12], temperature [13], and solvents [14], with the most appropriate process depending on the prepolymer type and the polymerization mechanism.…”

Enhanced Adhesion and Transmittance Uniformity in Laminated Polymer-Dispersed Liquid Crystal Films

We propose a two-step UV irradiation procedure to fabricate polymer-dispersed liquid crystal (PDLC) films by lamination. During the first UV treatment, before lamination, the UV-curable monomers coated on one film substrate are solidified through photo-polymerization as the phase separation between the liquid crystals and the monomers. Introducing an adhesion-enhancement layer on the other plastic substrate and controlling the UV irradiation conditions ensure that UV-induced cross-linkable functional groups remain on the surfaces of the photo-polymerized layers. Thereby, the adhesion stability between the top and bottom films is much improved during a second (post-lamination) UV treatment by further UV-induced cross-linking at the interface. Because the adhesion-enhancement and PDLC layers prepared by the bar-coating process are solidified before lamination, the PDLC droplet distribution and the cell gap between the two plastic substrates remain uniform under the lamination pressure. This ensures that the voltage-controlled light transmittance is uniform across the entire sample.
