“…% of dichroic dye does not increase conductivity of the system, anisotropy of conductivity and the amount of defects in LC layered structure, which act as centres for EHD instability. Otherwise EHD response time would decrease or stay constant [9]. On the other hand, the threshold voltage for dielectric reorientation of LC molecules in SmA phase is described by following equation [10]:…”

The spectral characteristics of light absorption and light emission processes in focal conic and homeotropic structures of smectic‐A liquid crystal containing dichroic dyes including fluorescent ones were obtained. The influence of dichroic dyes introduction on electro‐optical parameters of guest‐host liquid crystal mixtures is discussed. The results allow one to obtain high‐contrast monochrome or two colour grey‐scale images on a wide viewing angle multistable transflective SmA LCD (EASL DMD™, Electrically Addressable Smectic Liquid crystal Daylight Memory Display).

We have obtained a polymer wall-stabilized smectic A liquid crystal to be used for bistable flexible displays. The polymer wall structure optimally connects the two substrates together, thus providing maximum flexibility as compared to the polymer dispersed liquid crystal. Moreover, all the intrinsic bistable properties of the smectic A material are preserved. We analyzed the pixel performance and demonstrated very good electro-optical characteristics, high contrast ratio, and excellent stability of the states. The polymer wall-stabilized smectic A on flexible substrates has high potential to be used as electronic paper.

EASL displays based on the effect of electrically reversible memory in Smectic‐A LC features long term image storage capability and wide viewing angle. The reflective mode of SmA displays (PolyDisplay®) features a paper‐like readability and appearance, whereas their transmissive mode (Vindauge™) offers an outstanding transmission and opens new display application areas via see‐through transparent displays. Electro‐optical performance and approaches for its optimization for reflective and transmissive modes of EASL displays are discussed in this paper.
