Optical characteristics of a guest–host reflective liquid-crystal display with a phase compensator but no polarizing sheet and with positive image contrast
نویسندگان
چکیده
Computer modelling has been used to study the design of a guest–host reflective liquid-crystal display with a phase compensator, operating at the nematic–cholesteric transition. It is shown that, by choosing the parameters of the phase plate and the step of the helix of the chiral additive, it is possible to simultaneously obtain high reflectance and image contrast and also a moderate degree of multiplexing. © 2002 Optical Society of America

High Contrast and Fast Response Polarization- Independent Reflective Display Using a Dye-Doped Dual-Frequency Liquid Crystal Gel
We have developed a new guest-host reflective display using a dye-doped dualfrequency liquid crystal (DFLC) gel. By combining dye absorption and maximal light scattering, the display is polarization independent and exhibits a high contrast ( 230:1). The high reflectivity (R 50%) is because of the vertical aligned structure at 0 Vrms. The fast response time ( 5 ms) is also fast due to the freque...
متن کاملDevelopment of Highly Soluble Anthraquinone Dichroic Dyes and Their Application to Three-Layer Guest-Host Liquid Crystal Displays
The relationships between molecular structures and properties of anthraquinone dichroic dyes were studied and dyes with large solubilities and dichroic ratios were developed. The yellow anthraquinone dye behaves as a quencher of the coumarin dye, and the mixture has a large absorption coefficient without fluorescence. These technologies can enlarge the color reproduction area of three-layer gue...

We study optical properties of bistable reflective and transflective direct view ferroelectric liquid crystal displays (FLCDs). Single and double polarizer FLCDs with and without a retardation film are considered. Maximal contrast ratio versus optical retardation of liquid crystal layer for different configurations of FLCDs is calculated. Advantages and disadvantages of each configuration are d...
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...
متن کاملOptical Reorientation in Dye-doped Liquid Crystals
The nonlinear optical properties of liquid crystals received considerable attention in the past decades and were reviewed by various authors. Harmonic generation in liquid crystalline phases and optical reorientation of nematics are examples of nonlinearities studied in detail. The present paper deals with the latter effect, paying special attention to the influence of absorption on the process...
