The bistability, wide viewing angle, paper-like sunlight readability and outstanding transmission of displays based on the effect of electrically reversible memory in SmA LC fulfills the needs of certain application areas and opens new application possibilities. This paper focuses on the performance, manufacturing aspects and the current areas of SmA displays development. The simplicity of the display and its manufacturing has enabled PolyDisplay ASA to start commercialization of EASL DMD TM products based on SmA LC within a number of market segments.

“…There are a number of reflective display technologies emerging that can offer paper-like readability, including electrophoretic, electrochromic, electrowetting and suspended particle device types, as well as some LCD technologies. Electrically Addressable Smectic Liquid crystal Daylight Memory Display (EASL DMD™) technology, based on the effects of electrically reversible memory in smectic-A (SmA) phase of liquid crystals [1][2][3][4][5], is among the reflective display technologies providing paper-like readability.…”

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.

“…A physical principle of light modulation by smectic A (S A ) liquid crystal (LC) phase and stabilization of given transmission level after the field removal is based on alteration of light scattering properties of LC in electrical reversible memory effect (ERME). Focal conic (FC) and homeotropic (HP) phase structures with maximum and minimum light scattering correspondingly are formed during processes of electrohydrodynamic (EHD) instability and LC molecules dielectric reorientation [1,2]. The stability of main and intermediate light scattering levels is provided by visco-elastic properties of laminated medium.…”
