Abstract
In-plane electro-optical switching (IPS) is a natural feature of a conventional planar-aligned display cell based on the deformed helix ferroelectric liquid crystal effect (DHFLC-effect) with a sub-wavelength helix pitch, if the tilt angle is close to 40 degrees.
Highlights
Our approach is transformation of effective refractive indices significantly affect the propagation of light in based on the fact that when condition is fulfilled, the light transmission of a planar-aligned the deformed helix ferroelectric liquid crystal (DHFLC) layer
Note that the quantitative value of the tilt angle θ of molecules in smectic layers in helicoidal structures of ferroelectric liquid crystal (FLC) is determined by the level of saturation of the Ψd (E) experimental curve, whose behavior in the electric field (as well as ∆neff (E))
It is experimentally shown that the in-plane switching electrooptical mode can be observed in DHFLC cells with the sub-wavelength helix pitch
Summary
The simple manufacturing in planar-aligned deformed helix ferroelectric liquid crystal (DHFLC) cells [5]. Replacing the periodical helical nanostructure of DHFLC cells with macroscopic ellipsoids of effective refractive refractive indices (Figure 2) when analyzing light propagation through the structure will be effective certain wavelength λ, 2 and n ~ E2 in electric field E in combination with the main optical axis deflection on n+ ~ Figure
