P27-b: Optimization of Reflective LCDs with Phase Compensators
نویسنده
چکیده
Using the optimization criteria, called “Polarization Transformation Efficiency” (PTE), we have obtained the optimum operating voltages that enable to realize perfect dark and bright states in RTN-LCDs with phase compensators between the polarizer and LC cell. The delicate analysis showed, that if the PTE parameter is close to 1 a 700:1 duty ratio of RSTN-LCD with phase compensators having an average brightness of more than 30% and the contrast 9:1 can be realized. We believe that the proposed new method of LCD optimization can be successfully applied for the definition of new advanced LCD configurations with a high brightness, contrast and duty ratio.

Holographic directive reflectors for reflective color LCDs
RGB directive color reflectors were implemented for bright reflective color LCDs. The reflection gain at a white display state was suggested to be 3.5 times as large as the white standard. The color gamut was found to be as wide as the NTSC standard. There observed little color shifts within the directive angle.
متن کاملMeasurement of reflective liquid crystal displays
Cell gap thickness is one of the most important design parameters for liquid crystal displays ~LCD!. Existing measurement methods only apply to transmittive LC cells. These methods are obviously unsuitable for measuring the cell gaps of reflective LCDs with internal reflectors. This kind of LCD includes single polarizer reflective displays and liquid crystal on silicon displays. The objective o...

We propose the use of low cost alphanumeric liquid crystal displays (LCD) not only as an educational tool, to introduce students the insights of the electrooptic performance of liquid crystals, but also as a device able to be used in research to validate models describing the performance of LCDs and to be used in applications requiring monopixel optical modulation. High resolution LCDs have usu...
متن کاملControl Stability Evaluation of Multiple Distribution Static Compensators based on Optimal Coefficients using Salp Swarm Algorithm
In order to solve the problem of voltage drop and voltage imbalance in the distribution systems, the injection of reactive power by multiple static compensators is used. The distributed generation such as photovoltaic systems could play a role of the static compensators by producing reactive power. In this paper, the integral to droop line algorithm is used to control the reactive power in busb...
متن کاملبررسی متیلاسیون راهانداز p27Kip1 در بیماران مبتلا به کولیت اولسرو
Background & Aims: The CDK inhibitor (CDKI) protein p27kip1 (p27) negatively regulates cyclin D–CDK4 complex in the G1 phase. Alterations in the expression of p27 kip1 cause a degradation of cell growth and promote the development of various diseases. Aberrant methylation patterns have been reported in large number of diseases. The purpose of this study was to investigate the methylation ...
