P-85: Reflective Liquid-Crystal Cell-Gap Measurement Using Input-Polarization-Angle Dependence
نویسنده
چکیده
Surface-reflection component is blocked by the analyzer A simple technique of measuring a reflective TN liquid crystal (LC) cell gap using a laser is described. It utilizes a very unique property of strong input-polarization-angle dependence of the reflective LCs, which is not observed in the conventional transmissive LCs. This technique eliminates the surface-reflection problem which can be encountered by most other techniques using a monochromatic light source. Quantitative experimental results obtained have confirmed the validity of this scheme.

A New Method for Liquid Crystal Cells Twist Angle and Cell Gap Measurement
A new simple, fast and accurate method for liquid crystal cell twist angle and cell gap measurement was demonstrated. It is based on a real time spectral measurement of the linear polarization preservation modes. Prior knowledge of the twist angle or director orientations is not required. This method is straight forward and does not require complicated calculations or curve fitting. This system...
متن کاملReflective twisted nematic liquid crystal displays. II. Elimination of retardation film and rear polarizer
Reflective twisted nematic liquid crystal displays consisting of just one input polarizer, a liquid crystal cell, and a rear reflector are discussed. We first show that all such display modes reported in the literature can be depicted systematically in a series of parameter space diagrams. Then by making use of such diagrams as a guide, we show that other new high quality reflective display mod...
متن کاملMeasuring Thickness and Pretilt in Reflective Vertically Aligned Nematic Liquid Crystal Displays
Pretilt angle is a parameter of the utmost importance in the ultimate performance of vertically-aligned negative nematic LC displays. When these devices work in reflective mode, as is the LCOS microdisplays, accurate measurement of pretilt angles becomes a difficult problem, since usual experimental setups based on retardation of the polarization components of the impinging light are proportion...
متن کاملOptimization of reflective bistable twisted nematic displays with retardation compensation
The contrast ratios of reflective bistable twisted nematic liquid crystal displays with a rear quarter-wave film are optimized by means of a parameter space approach. By plotting the contrast ratio as a function of the twist angle and thickness-birefringence product (dDn) of the display, the regions where the displays show the best contrast ratio are clearly shown. Both the absolute reflectance...
متن کامل15.4: Reflective LCD Cell Gap Measurement by QHQ Compensation Method
A phase compensation method is presented for measuring the cell gap of reflective LCD. We use the so-called QHQ compensator that is made up of two quarter-wave plates (Q) and one half-wave plate (H). This method is different from other compensation methods in that we can change both the orientation angle and retardation value of the compensator by rotating the quarterwave and halfwave retarders...
