25.3: Optimized Phosphors for Field Emission Displays
Authors: Cummings B. , Pearson R. , Kajiwara K. , Kato Y. , Hatano Y. , Ito Y. 
Published: January 2005

AbstractCandescent Technologies and SONY have developed the first commercially viable, full color, high performance field emission display (FED) which combines the premium visual performance of a color CRT in a thin flat panel package. Because of the similarity between the FED and CRT electron excitation, the FED can use the conventional P22 color CRT phosphor triad. However in this paper we will show improved performance for screens based on phosphors optimized for the lower accelerating voltage of the FED (7–10 kV). Data will be presented showing screen performance in full color FED's including color gamut, white screen brightness and luminous efficacy. This data will compare optimized phosphors with the P22 color CRT phosphors. The most striking improvement has been seen for the ZnS:Ag blue phosphor where the optimized phosphor shows higher efficacy, superior color saturation, and improved maintenance of efficacy with coulombic aging when compared to the P22 blue phosphor. Factors which influence the phosphor performance will be discussed including activator and co‐activator concentration as well as phosphor crystal structure as measured by cross sectional TEM.

Published: January 2005

AbstractThe optical performance of ferroelectric liquid crystal over silicon (FLCOS) microdisplay devices can be greatly improved by ensuring that the silicon backplane that forms the core of the display engine is both smooth and flat. In this paper we investigate the effect of the circuit design and manufacturing process on the bow of the silicon CMOS drive circuitry.

P‐1: A New TFT‐LCD Panel Structure with High Aperture Ratio and Small Signal Delay by fabrication TFT in Line‐Crossover
Authors: Park J. W. , Lee M. C. , Kim J. S. , Kim C. H. , Han M. K. 
Published: January 2005

AbstractWe have proposed and fabricated a poly‐Si TFT integrated gate‐data line‐crossover structure in order to increase the aperture ratio and to reduce the signal delay. The poly‐Si TFT is integrated in the gate‐data line‐crossover without sacrificing the electrical characteristics so that the aperture ratio of the panel was improved by about 3% because the TFT is located under a metal line. We employ a low dielectric air‐gap between the gate‐data line crossover, which reduces the capacitance between the gate and the data lines, so that the signal delay of the data line is decreased significantly. The fabricated TFT was successfully operated, and the proposed structure reduces the delay time by about 9 times compared with the conventional panel that does not employ any air‐bridges.

P‐11: Effect of Optical Phase Shift on MTF‐Based Metrics of Image Quality
Authors: Lloyd Charles J. 
Published: January 2005

An evaluation of image quality showed phase need not be accounted for in addition to modulation transfer function (MTF) for lenses typical of those found in commercial flight simulators.
P‐12: Display Image Quality Evaluation with Multi‐Scale Human Visual Model
Authors: Yu Jen‐Hung , Lin Yen‐Chung , Shieh Han‐Ping D. , Liaw Ming‐Jiun 
Published: January 2005

AbstractA multi‐scale human visual model is utilized to evaluate image quality and to reproduce image on display devices close to original scene. The major advantage of this evaluative method is that the results are well correlated with subjective human perception. Human perceived image quality does not improve with much higher luminance and contrast ratio for both CRTs and LCDs. The requirements to achieve high human perceived image quality are discussed. Moreover, the evaluative results can also be used to define the characteristics of display devices.

Published: January 2005

AbstractA novel patterning technology of fine‐pitched carbon nanotube (CNT) pixels on a thin metal has been developed by lift‐off process for field emitter arrays (FEAs). The lift‐off method provides even smaller CNT pixels compared with those made by conventional screen‐printing and photolithography processes. SEM images demonstrated that the smallest pitch and the size of patterned pixels were 15 μm × 15 μm and 7 μm × 7 μm, respectively. After patterning and heat treatment process at 300°C, most of CNT bundles on the cathodes were aligned perpendicular to the substrate. The density of CNT bundles in the patterned pixels was 10–20/μm2. The turn‐on field of patterned CNTs was less than 2.5 V/μm and the current density was 3.2 mA/cm2 at 3.5 V/μm.
P‐49: Dependence of Dark Spot Growth on Electrical Stressing Voltage in OLED Devices
Authors: Lin Karen Ke , Chua Soo Jin , Lim Shuang Fang , Wei‐Wang  
Published: January 2005

AbstractThe formation of dark spot in OLED devices has long been identified as pinholes on the protective layer that creates pathways for water or oxygen permeation and causes the cathode delamination and chemical change. In this work, we demonstrate that using micro‐sized silica particles to create uniform sized defects on protective layer is an efficient way of controlling the location and the number of dark spots. The dark spot growth was then studied at different driving voltage in the range from turn on voltage to about 11V, dark field microscopy was used to observe dark spot growth behaviour when device is driven lower than turn on voltage. Our observations indicate that the growth was strongly affected by the electrical stressing voltage. In other words, the chemical and physical changes reflected by the growth are speeded up with the increasing driving voltage. We discuss possible mechanisms for these degradation processes also.
P‐50: Morphology and Luminescence Property of Gd2−xYxO3:Li, Eu (0.0 × 0.8), Red‐Phosphor with High Efficiency at Low Voltages
Authors: Byeon Song‐Ho , Ko Mi‐Gyeong , Park Jung‐Chul , Kim Dong‐Kuk , Suh Kyung‐Soo 
Published: January 2005

AbstractThe single phased Gd2−xYxO3:Li, Eu solid‐solution was successfully prepared by a citrate method at 650. Such a temperature is much lower than the typical solid‐state reaction or spray pyrolysis temperature (> 1300). However, additional heat treatment up to 850 ∼ 900 was required to obtain the optimum optical properties. Photoluminescence (PL), cathodoluminescence (CL), and morphology of Gd2−xYxO3:Li, Eu system were compared as a function of x values. The PL and particularly CL emission intensities at low‐voltages (< 1 kV) of this solid‐solution were 50 ∼ 80 % higher than those of commercial red phosphor Y2O3:Eu in the range of 0.0 × 0.8. This phosphor material appears to be very promising for field emission display (FED) because the particle size and shape are easily controlled at low temperature (900) by the change of Y or Li contents without any significant loss of brightness.

P‐57: Striation Phenomenon of Plasma Display Panel (PDP) Cell and Its Application to Efficiency Improvement
Authors: Shon C. H. , Lee J. K. , Kim H. C. , Dastgeer S. , Yang S. S. , Shin S. W. 
Published: January 2005

AbstractThe first observation of striation in plasma display panel (PDP) cell by kinetic and fluid simulations is presented. The striation phenomenon in the kinetic simulation is clearer than that in fluid simulation. The striation is due to the self‐consistent interaction of plasma, dielectric wall, and applied voltages. Simulation results indicate that the phenomenon occurs due to the non‐uniform accumulation of surface charges on the sustain electrodes, which consequently deform the local potential profile. The surface and space charges locally create multiple‐tier potential distribution near anode region that makes plasma bunches. The discharge in this region is governed by ionization process, but the cathode discharge depends on the secondary‐electron emission process on the dielectric surface. Based on these discharge characteristics, 80 % efficiency increase of PDP cell is obtained due to triggered striation by the modification of front dielectric material and MgO protective‐layer.

P‐67: Applications of New Photoalignment Materials Containing Cinnamoyl Group
Authors: Kim Jinyool , Kim Sanghee , Park Kyusoon , Kim Taemin 
Published: January 2005

AbstractLiquid crystal alignment performance of a series of polymethacylate based photopolymers containing cinnamoyl group and their applications have been investigated. By illuminating linearly polarized UV light on the film of the photopolymers, strong azimuthal anchoring energy was induced and liquid crystal alignment on the photopolymer film was thermally stable up to 150 °C. Photochemical stability appeared to be dependent on the mode of alignment. Pretilt angle was controllable from 0 to 90 degree by changing the amount of UV dose, incident angle, parameters of liquid crystal, along with slight structural modifications of the photopolymer. Applications to current LCD modes such as TN, VA, IPS, STN and the film application for phase compensation and retardation have also been studied.

P‐70: Aligning Properties and Anchoring Strength of Antiferroelectric Liquid Crystals
Authors: Park Won Sang , Kang Jin‐Woo , Lee Seo Hern , Choi Duck Woon , Kim Sung‐Chul , Kim Jae Chang , Yoon Tae‐Hoon 
Published: January 2005

AbstractExperimentally, the aligned direction of AFLCs in electro‐optic cells having both the substrates rubbed along the same direction, is skewed by a few degrees from their rubbing direction. We propose ‘Torsional Rigid Body Model’ to explain the reason, and interpret their skewing angle as the action of short pitch of AFLCs with an antipolar order where the direction of local polarization alternates between adjacent layers. Several cells have been fabricated for test purposes. Our experimental results indicate that when the azimuthal anchoring strength in the electro‐optic cell is smaller than the maximum shear stress due to short pitch of AFLCs then their layer normal axes are skewed, and the skewing angles become smaller according to a decrease of the surface anchoring strength
P‐74: Defect‐Free FLCD with C‐2 Uniform State: Analysis and Fabrication
Authors: Xu J. , Kurihara R. , Murakami Y. , Yamashita T. , Kobayashi S. 
Published: January 2005

AbstractHow to obtain defect‐free ferroelectric liquid crystal displays(FLCDs) is the most important problem in developing liquid crystal displays(LCDs). In this report, a phenomenological theory of transition between C‐1 state and C‐2 state in FLC cell has been firstly suggested. Theory the free energy that includes bulk elastic and surface parts has been simulated depending on the parameters such as surface topography, anchoring energies, thickness of LC medium and so forth. The critical conditions of the state transition from C‐1 to C‐2 have been determined. Based on this theory, we succeeded in fabricating defect‐free FLCDs with uniform C‐2 state by rubbing and that with uniform C‐1 by photoalignment technique.

Published: January 2005

AbstractAntiglare AG and low‐ or anti‐reflection LR, AR are important optical features of the front surfaces of flat panel displays and other information displays. New types of holographic surface relief microstructures have been developed on large areas showing very good optical properties. Holographic exposure techniques give the freedom to carefully design AG properties. They also allow the superposition of different types of structures, e.g. a Motheye AR and an AG microstructure MARAG ™ 1, which can be produced very cost‐effectively by mass UV precision nano‐replication UV‐PNR. As a bonus, the UV‐PNR structures are hardcoat materials suitable for the real world.
