FLC Fundamentals

Bistable alignment

In a collaboration with researchers at Kent State University, we have developed alignment techniques based on oblique evaporation of SiOx that allow us to make bistable FLC devices.

Manufacturing metrology

Flatness of the silicon backplane is a key requirement for the production of LCOS devices. Displaytech has developed a non-contact measurement technique that reliably characterizes planarized silicon wafers in a way that correlates well with LCOS gap uniformity.

Diffractive optics

In addition to their use between crossed polarizers as intensity modulators, FLC devices are well-suited for making diffractive modulators where they can completely modulate unpolarized light.
