Polymer Network Morphology and Electro-Optical Properties of Electrothermal Switchable Bistable Polymer-Stabilized Cholesteric Texture Light Shutters with Various Chiral Dopant Concentrations

Bistable Cholesteric Liquid Crystal Films with Excellent Electro-Optical Performance and Spacing Stability for Reflective Displays

“…This is attributed to the fact that the selective reflection bandwidth Δλ = Δ n × p of the CLCs is located just in the visible-light region, where Δ n = n e – n o is the birefringence of the liquid crystal (LC), n e is the extraordinary light refractive index, n o is the ordinary light refractive index, and p is the pitch of the CLCs . In addition, due to the ability to maintain a stable optical state after removing external stimuli, bistable electro-optical devices based on CLCs show the advantages of ultralow power consumption, long image storage time at zero electric field, and no backlight. , Consequently, CLCs have been extensively studied and widely used in the fields of displays, − OLEDs, light shutters, − gratings, , light filters, smart glasses, anticounterfeiting labels, optical vortex processors, and spatial phase modulators …”
