P‐97: Phase Compensator Method for Cell Thickness and Twist Angle Measurements in a Reflective Twisted Nematic LC Cell
Authors: Gwag Jin Seog , Han Kwan‐Young , Yoon Tae‐Hoon , Kim Jae Chang 
Published: January 2005

AbstractWe propose a simple and accurate measurement method to determine cell gap and twist angle of a reflective twisted‐nematic liquid crystal (TNLC) cell by using a phase compensator. A single wavelength source (red or green laser) is used for cell gap measurement and two wavelength sources (red and green lasers) for a twist angle measurement. The proposed measurement method can be applied to low cell gap as well as high cell gap.

15.4: Reflective LCD Cell Gap Measurement by QHQ Compensation Method
Authors: Yu X. J. , Kwok H. S. 
Published: January 2005

AbstractA 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. As a result, the QHQ compensation method has a higher accuracy and a simpler procedure.

17.1: Design of a Tool to Benchmark Scaling Algorithms on LCD Monitors
Authors: Vicario Elena , Heynderickx Ingrid , Ferretti Giulio , Carrai Paola 
Published: January 2005

AbstractScaling algorithms, which are used to resize images displayed on e.g. LCD monitors, may introduce artifacts, and affect the overall quality of the displayed image. By means of three subjective assessments, we designed a tool to benchmark the performance of these scaling algorithms in terms of image quality preservation. In particular, we selected critical image material, classified the artifacts that may occur as a consequence of scaling and combined a preference analysis with an artifacts analysis. As a result, we present a relation between the overall image quality as judged by end‐users and the importance of the various artifacts.

Authors: Maeda Kazuhiro , Tsujino Sachio , Takahasi Keiji , Kubota Yasushi , Imai Shigeki , Nakagawa Hirohide , Katayama Mikio 
Published: January 2005

AbstractThis paper describes a highly versatile “System LCD” which has been developed for mobile applications. A key feature of the display is a multi‐format capability to enable both the color depth and the spatial resolution to be dynamically controlled according to the application. This advanced functionality is realized by integrating a novel source‐driver, binary‐driver and clock‐generator onto the panel. A 3.7″ LCD with three principal display formats has been successfully fabricated using low temperature CG‐Silicon technology. The power consumption in each format has been measured at 14mW for VGA/Full‐color, 8mW for QVGA/Full‐color and 2mW for QVGA/Monochrome. We believe this versatile display technology, which combines both high performance and low power consumption, will be essential for the next generation of mobile products.

Published: January 2005

AbstractWe developed an active‐matrix liquid‐crystal display on the plastic substrate using hydrogenated amorphous silicon thin film transistor (a‐Si:H TFT). TaOx film on both side of substrate was deposited in order to reduce gas permeation to plastic substrate and protect it from chemical attack during TFT process. The substrate bending caused by the thermal stress could be released with the island patterning of the inorganic layers. A prototype 2″ TFT‐LCD was demonstrated with a maximum process temperature of 150 °C.
23.1: Invited Paper: Isoluminous Color Difference Metric for Application to Displays
Authors: Brill Michael H. , Silverstein Louis D. 
Published: January 2005

AbstractThis paper provides a methodology which bridges the gap between a simple color‐difference metric and a full spatio‐chromatic vision model to predict color differences. Because luminance and chromatic visual channels differ greatly in their spatial sensitivities, more than a single number is needed for specific applications—e.g., performance of softcopy displays. On the other hand, a full vision model implies dependence on the displayed images as well as on the display device, and may be impractical to implement. The compromise proposed here is to adopt in certain cases two color‐difference metrics, one for luminance and the other for chrominance. Because chromatic coordinates are not luminance‐independent in uniform color spaces such as CIELAB, the endpoints of the color difference are made isoluminous prior to transformation to a uniform‐color space.

AbstractColor tracking in an LCD, which is defined as chromaticity dependence on brightness, is analyzed in terms of the director configuration of liquid crystal with voltage. We have developed an Authentic‐color IPS, using an optimized backlight and a lower retardation panel, which can avoid color tracking. The chromaticity difference between black and white representation is below the limit of perception.

Published: January 2005

AbstractMicrostructured films as optical components have become more and more important for information displays recently. Such films can act as light management components, that distribute light uniformly in LC displays or on rear projection screens. Glare control and AR can be achieved using microstructures on the front surface of displays. Recently developed large area holographic exposure techniques combined with mass replication allow a very precise definition of the optical properties of such light‐weight, cost‐effective films.

26.1: Optical Films for Reflective LCDs to Achieve High Image Quality
Authors: Yoshimi Hiroyuki , Yano Shuji , Fujimura Yasuo 
Published: January 2005

AbstractCharacteristics of reflective LCDs, which have gained a lot of notice in recent years, rely largely on optical design of circular polarizers and the quarter‐wave plates, as a component. Important design includes wavelength dispersion, viewing angle, uniformity of display and matching of refractive index. Our work has contributed to improving performance of reflective LCDs by enhancing the characteristics of polymer film using stretching and optical lamination technologies. To design that offers higher contrast and wider viewing angle, we have discovered that it is necessary to control viewing angle variation of the polarizing axis in order to compensate for the viewing angle of the polarizing film as well as the optical anisotropic properties of liquid crystal. Applying this technology to circular polarizers used for reflective LCDs enables design of wide viewing angle circular polarizers. In order to realize higher contrast for reflective LCDs, it is also necessary to design other optical materials including polarizing films. For design of hybrid optical film, it is particularly necessary to reduce surface reflection and interface reflection. This paper also reports our findings concerning this topic.

Published: January 2005

AbstractWe demonstrated a silver gate hydrogenated amorphous silicon thin film transistor(a‐Si:H TFT) using thin buffer layers of alumina(Al2O3) and aluminum‐nitride(AlN). An Al2O3 layer on glass substrate was deposited so as to increase adhesion between APC(> 98 wt% silver) and glass substate. An AlN layer on APC was deposited to prevent it from plasma damage during silicon‐nitride(SiNx) deposition. The Ag gate a‐Si:H TFT with these buffer layers exhibited a field‐effect mobility of 1.15 cm2/Vs, a gate voltage swing of 0.86 V/dec. and a threshold voltage of 2.5 V.

33.1: Invited Paper: Image Quality is FUN: Reflections on Fidelity, Usefulness and Naturalness
Authors: de Ridder Huib , Endrikhovski Serguei 
Published: January 2005

AbstractDifferences in perceived naturalness and image quality have led to an information‐processing approach towards understanding image quality, thus challenging the traditional, signal‐processing approach. This paper presents a general image quality model integrating both approaches. The model assumes the existence of three constraints, i.e. fidelity, usefulness and naturalness. Image quality is modeled as the weighted sum of these constraints whereby the weighting depends on task, context, image content etc. Model predictions will be confronted with experimental data on optimizing color reproductions of natural scenes.
