چکیده

The inter-grey-level response times of an LCD are studied using two different approaches: a 3-D finite-elements dynamic director orientation model and a simple firstorder RMS model. Both approaches are compared with measurements, showing that for certain applications, the RMS model is a quick and sufficiently reliable response time prediction tool.

20.3: Photo-aligned Ferroelectric Liquid Crystal Display with Memorized Gray Scale

The new concept of the passive matrix ferroelectric liquid crystal display (FLCD) with a memorized grey scale is proposed. The physical origin of the gray scale in ferroelectric liquid crystal display is considered. The criterion of reliable bistability is derived dependent on FLC hysteretic behavior in electric field. A new approach for multiplex electronic addressing of the FLCD grey scale is...

Non-uniform Theory Simulations of the Continuous Director Rotation Mode of FLCD’s

We introduce the theoretical model of LC material with the phase sequence I-N-SmC as a material having suitable properties for multimedia applications (fast speed, high contrast and full grey scale capabilities). We present the structure and investigate the switching and the optical response of the device taking into account material and technological parameters. We explain the mechanism of the...

Directional Filter Banks for detecting un-patterned TFT-LCD defect

The thin film transistor liquid crystal display (TFT-LCD) has become an actively used front of panel display technology with an increasing market. Intrinsically there is a region of non uniformity with low contrast that to human eye is perceived as a defect. Because the grey-level difference between the defect and the background is small, the conventional edge detection techniques are hardly ap...

Dual-Frequency Addressed Infrared Liquid Crystal Phase Modulators with Submillisecond Response Time

Dynamic response of a dual-frequency liquid crystal (DFLC) based near infrared phase modulator is investigated through numerical simulations and experiments. The relationships between the optical response times and various voltage driving conditions are studied. An optical phase retarder operating at 1.55 lm wavelength is demonstrated by using our homemade high figure-of-merit DFLC mixture. To ...

Fast-Switching Stratified Polymer-Stabilized Liquid Crystal for Flexible Display Applications

A new liquid-crystal device for flexible display applications was developed using twofold polymerization process. The cell was fabricated from a homogeneous mixture of a liquid crystal and a polymerforming material. Caused by the spatially nonuniform rate of polymerization and wetting properties, largescale anisotropic phase separation of the liquid-crystal blend and the polymer precursor leads...
