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.

Very little research in knowledge discovery has studied how to incorporate statistical methods to automate linear correlation discovery (LCD). We present an automatic LCD methodology that adopts statistical measurement functions to discover correlations from databases attributes. Our methodology automatically pairs attribute groups having potential linear correlations, measures the linear corre...

Liquid crystals exhibit orientation-dependent phases ranging from a disordered ~isotropic! phase to a highly ordered crystalline phase. In between these extremes, increasing order can result in nematic and smectic phases. Typically, molecular simulation studies of liquid-crystal behavior use a nonspherical hard-body monomer. In this work, molecular simulation is used to study dimers of hard pro...

2014 This article presents a qualitative approach of the relationship between the occurrence of crystal defects and the disturbances of the induced birefringence which appear during the operation of (001) D-KDP solid-state light-valves. The crystal defects are ascribed to growth or seed effects, and both contributions to the above disturbances are discussed. On this basis, conclusions are drawn...

The pulsed backlight system has been introduced for reducing motion blurs of LCDs in high motion pictures. But applying the pulsed backlight, full screen flicker and inconsistency of transmissivity for entire frame at a lightening time should be considered. This paper discusses the analysis of blurs in high motion pictures and proposes the design method for more suitable display terminal of LCD...

Gray shades are essential to reproduce images on displays. Amplitude modulation technique allows a large number of gray shades to be displayed in liquid crystal displays (LCDs). Number of voltage levels in the addressing waveforms of amplitude modulation is at least twice the desired number of gray shades. Hence, hardware complexity of the column driver is high as compared to other techniques f...

The development of high-performance liquid chromatography (HPLC) in the years of 1965 to 1985 was undeniably a success story. However, an important limitation of the technique remained: in comparison to capillary gas chromatography the resolving power accessible in a reasonable analysis time is poor. The introduction of a range of miniaturized liquid phase techniques, exploiting either pressure...

This paper describes the viscosity variation of a liquid crystal under electric field, and its application to a controllable sliding bearing. Liquid crystal is known as a homogeneous organic liquid characterized by the long-range order of its molecular orientation. When an electric field is applied to a liquid crystal film as lubricant, the orientational order of molecules become parallel to th...

In this seminar, the liquid crystal elastomers (LCEs) and their building blocks – liquid crystals and polymers are presented. The specific rod-like molecular shape of liquid crystals forces LCEs to form a special molecular distribution of the underlying polymer network. This allows them expand up to 400 % with temperature, which could be used in applications. The physics of this spontaneous dis...

This paper gives an overview of dynamic polarimetric imaging techniques. Various methods are reviewed. Techniques using liquid crystal devices, incepted in the late 1990’s, are emphasized. Practical implementations are presented. We particularly focus on high-speed techniques (ie faster than 200 Hz).
