Liquid crystal applications in displays and photonics: new possibilities

Liquid crystal (LC) devices for displays and photonics are dominating in the market and will be the basic technology for advanced display and electronics in the nearest 10 years. Photoalignment materials can be effectively used in LC alignment and patterning for new generations of LC devices that provide extremely high resolution and optical quality of alignment both in glass and plastic substrates, photonics holes etc [1].

The aim of the Course is highlighted below:

to summarize basic electrooptical phenomena, as a basis for liquid crystals devices;

to introduce new liquid crystal technologies, such as photoalignment and photopatterning;

to show new photonics applications of liquid crystals: LC optical elements for fiber optical communication systems; adaptive optics; Photonic crystal/liquid crystal devices; LC modulators;

to describe new liquid crystal displays: AR/VR, 3D, optically rewritable (ORW) E-paper, field sequential color ferroelectric liquid crystal (FLC) LCOS projectors,   photo-patterned quantum rods and 100% polarizers, q-plates,   LC sensors, switchable lenses, smart windows with voltage controllable transparency, security films, switchable antennas [2].
