P‐52: Luminescence Properties of Pr‐Doped Perovskite Titanate Phosphors
Authors: Kang Seung‐Youl , Byun Jung‐Woo , Kim Jin Young , Suh Kyung‐Soo , Lee Jin Ho , Cho Kyung Ik , Kang Seong‐Gu 
Published: January 2005

AbstractWe presented luminescence properties of various perovskite titanate phosphors like ATiO3:Pr3+ (A = Ca, Sr, Ba, Ca1−xBax, Sr1−xBax). Especially, the effect of Ga addition on the luminescence properties was of our interest. Without the Ga addition, the SrTiO3:Pr3+ and BaTiO3:Pr3+ rarely showed red luminance, while the CaTiO3:Pr3+ phosphor had very intense red luminescence at low concentration of Pr. The Ga addition caused the luminescence enhancement for all of the above perovskite titanate phosphors, especially, the SrTiO3:Pr3+ showed the most outstanding enhancement. Also, we investigated the effects of the change of the A‐site in the perovskite phase, ATiO3. While the partial replacement of Ca with Ba led the lumincescence to decrease, the partial substitution of Sr with Ba of 20 mole % led the luminescence to increase about 2 times.
P‐55: A New Test for the Presence of Eu3+ in Eu2+ Doped Phosphors. Eu3+ has been found in Plasma (BaMgAl10O17:Eu2+) and Long Persistence (Sr4Al14O25:Eu2+, Dy3+) Phosphors

Published: January 2005

AbstractStokes and anti‐Stokes emission from Eu3+ doped lattices has been observed on excitation with the 632.8 nm line of a He/Ne laser. These lattices include Y2O3, YNbO4 and YVO4. A test for Eu3+ in Eu2+ phosphors has been developed enabling the assessment of purity of Eu2+ containing long persistence and plasma phosphors. This has implications for new synthetic routes to these phosphors.
P‐60: The Effects of Barrier Ribs on Address and Sustain Discharges in PDP Studied by Three‐dimensional Simulation
Authors: Chung Woo Joon , Seo Jeong Hyun , Yoon Cha Keun , Kim Joong Kyun , Jeong Dong Cheol , Whang Ki‐Woong 
Published: January 2005

AbstractThree‐dimensional fluid code was used to investigate the effect of barrier ribs on the addressing and the sustaining discharges. The barrier rib height and the cell pitch are the main parameters used in this study. The lower barrier rib height allows the faster addressing but requires the higher sustain voltage, while the wider cell pitch allows the lower address and sustain voltages. We used the voltage transfer curve to analyze the sustain period.

Authors: Goodarzi A. , Foumani A. Akhavan , Mohajerzadeh S. , Gitibin M. , Miri A. , Khakifirooz A. , Soleimani E. Asl 
Published: January 2005

AbstractA novel pixel structure is proposed in which plasma is generated laterally between two electrodes. Unlike conventional PDPs, where the electrodes are defined on two different substrates and their spacing is controlled by barrier ribs, the spacing in this technique is adjusted by photolithography. Also the structure used in this approach does not need transparent conductors like ITO. The isolation of the electrodes is possible by a silicon‐nitride layer. Measurement results for 50×70μm2 pixels are presented.

Published: January 2005

AbstractIn this work, we have improved new tubeless packaging technologies using an indirect glass‐to‐glass electrostatic bonding and an organic binder bonding to the PDP. Both methods were performed more at less temperature than 200°C. AC‐PDPs were successfully packaged in He‐Ne(27%)‐Xe(3%) and the packaging properties were compared with conventional method. We observed light emission and the operation characteristics as function of time variation were investigated. Also, we proposed next generation packaging method.

Published: January 2005

AbstractA new driving technique of applying the auxiliary pulses to only the address electrodes with the blue phosphor layers during sustain‐period is proposed to improve the color temperature of an AC‐PDP. This auxiliary pulses can increase the intensity of blue light, such that the color temperature of an AC‐PDP can be improved without any modification of cell structure and degradation of image quality.
P‐66: New Photo‐Alignment Technology Based on Chalcone Moieties: Molecular Design and Process Development
Authors: Nakata S. , Kimura M. , Kumano A. , Takeuchi Y. 
Published: January 2005

AbstractIn this paper, factors affecting the pretilt angle are investigated for our newly‐developed photo‐alignment materials. We believe that two factors are crucial for the pretilt angle generation. That is, surface tension of the alignment films, and the incident angle of the LPUV light which may affect the surface order degeneracy. In addition, our development efforts of the photo‐alignment materials will be shortly summarized.

Published: January 2005

AbstractBy investigating the balance between surface azimuthal anchoring energy and bulk elastic energy within the confined chevron layer geometry of C1 and C2 states, we propose that it is possible to get zigzag free C1 state by low azimuthal anchoring alignment at low pretilt angle. Its relationship with elastic constant, chevron angle as well as surface topography effect are also discussed.
P‐75: Optical Performance of Compensated Normally Black and Normally White TN Modulated PLLCDs
Authors: Ahn S.‐H. , Davey A. B. , Crossland W. A. 
Published: January 2005

AbstractThe possibility of obtaining a wider and symmetric isocontrast region around normal incidence in the polar diagram for Normally Black (NB) and Normally white (NW) active matrix TN modulated PLLCDs is investigated. Using an extended Jones matrix approach and Poincare sphere representation for an obliquely incident beam, the effects of several compensation means are studied for TN‐PLLCD. We find that NB TN modulated PLLCD shows a better integrated contrast ratio (ICR) than that for NW over all collimation angles and is more responsive to compensation.
P‐76: Numerical Simulations of Nematic Liquid Crystal by Finite Difference Method
Authors: Ou C. R. , Ho G. S. , Yoo C. J. , Seng W. 
Published: January 2005

AbstractIn spite of the fact that many simulation programs have already been commercialized, this article provides a reliable methodology for the simulation of the director field of liquid crystal. The present method is easier to be applied than ref. [1,2], especially in various asymmetric pretilt orientations and twists angles. Through this technique, ITRI/OES is developing a series of spreadsheets. Present work is simple and easy to be extended to dynamics and two/three dimensional simulations. The giving grid test also shows that for small discrete numbers the errors will become serious while position is near the rubbing surface. Some of the published simulation works do not mention about this.
8.2: Transformation of Electron Emission Behavior on Mo‐tip FEAs by Diamond‐Like Carbon Coating
Authors: Jung Jae‐Hoon , Park Gong‐Seok 
Published: January 2005

AbstractWe have demonstrated that DLC coated Mo FEAs are very stable under operation when the hydrogen‐free DLC film is deposited by a layer‐by‐layer deposition technique using PECVD. In order to optimize the preparation condition of the DLC film, the thickness of the DLC layers on the Mo tips were changed from 10 nm to 100 nm. The turn‐on voltages for pure Mo‐tip FEAs are about 60, and 51, 46, 54 and 78 V for thickness of 10, 20, 50 and 100 nm, respectively. In addition to the decrease in turn‐on voltage, the anode current is also increased by adopting a DLC layer on Mo FEAs except for the case of the 100 nm thick DLC coating. Therefore, it is confirmed that the operating voltage of Mo FEAs can be remarkably decreased by DLC coating. Furthermore, the emission patterns from a layer‐by‐layer DLC coated FEAs were found to be more stable compared to conventional Mo FEAs.

Published: January 2005

AbstractThe electro‐optic properties of polymer networked liquid crystals formed in an electric field show that the polymer network tends to align the liquid crystal molecules in the direction the director had during exposure, with a strength depending on the concentration of the polymer network, and suggest that the polymer network is not distributed uniformly throughout the cell thickness.
P‐83: A New Reflective Twisted Nematic Liquid Crystal Display Mode with Large Cell Gap for Direct View Applications
Authors: Chen Jun , Kwok Hoi‐Sing 
Published: January 2005

AbstractWe propose a new reflective twisted nematic display mode, which is called the second minimum RTN mode. This mode has a larger dΔn value compared with the first minimum RTN mode which we proposed previously. A cell gap of 7 μm or larger can be used for this mode which makes the fabrication processing of this kind of reflective LCDs easier and more compatible with that of TN LCDs. The color dispersion in both bright and dark states of this display mode is small, and the response is reasonably fast considering the 7 μm cell gap. This display mode can be used in conjunction with TFT active matrix for high quality reflective displays for PDAs, and cell phones. It is also suitable for passive low cost applications such as watches and games.

8.3: Operation of FEAs in Hydrogen and the Development of Thin Film Metal Hydrides for Integration into FEDs
Authors: Chalamala Babu R. , Reuss Robert H. 
Published: January 2005

AbstractWe demonstrate that having hydrogen inside the operational ambient of field emission displays results in significantly improved display life. However, improving device performance by incorporation of gas phase hydrogen into thin glass packages is a difficult task. In this paper, we report on the development of solid state hydrogen sources utilizing thin film metal hydrides, which can be easily integrated into field emission displays. We show that these metal hydride thin films provide a practical means to incorporate solid state hydrogen sources into field emission displays. Using stainless steel anodes coated with TiH2 thin films, we demonstrate the successful operation of molybdenum field emitter arrays without emission current loss for 400 hours of continuous operation. Comparable arrays operated in the absence of hydrogen, but in an ultrahigh vacuum had emission current degradation of over 50% in less than 100 hours of operation.
4.2: Polymer Network‐Stabilized Monostable FLCDs Using Cholesteric‐Chiral Smectic C Phase Transition Material
Authors: Choi Suk‐Won , Choi Su‐Seok , Shin Hyun‐Ho , Kwon Soon‐Bum 
Published: January 2005

AbstractIn this paper, we propose a polymer network‐stabilized mono‐stable FLCDs using Ch‐SC* phase transition material. We have confirmed mono‐domain characteristics had been kept stable throughout the cycle of temperature transition; from SC* phase to the isotropic phase or Ch phase and back to the SC* phase. This method is quite effective to prevent undesirable generation of random two domains under the thermal treatments. So, additional alignment process that makes mono‐domain phase by a DC field is no more necessary. We investigated its EO properties and developed the prototype 14.1″ diagonal full‐color display for practical use, the performance of which is reported.

Authors: Ishinabe Takahiro , Miyashita Tetsuya , Uchida Tatsuo 
Published: January 2005

AbstractOne polarizer type reflective LCDs require a quarter wave plate. However, conventional quarter wave plate using uniaxial retardation films have poor viewing angle and high wavelength dependences. In this paper, we designed a quarter wave plate with wide viewing angle and wide wavelength range by using three biaxial retardation films. In addition, we realized a high quality reflective LCD with wide viewing angle range and high contrast ratio by applying this quarter wave plate and wide‐view polarizer to the R‐OCB cell.

Published: January 2005

AbstractThis article presents a methodology on the analysis of the thermal effects in the ColorQuad™ for the image quality. ColorQuad™ is one of the most promising optical components in the projection display system. Various types of thermal effects might occur in optical system. ITRI/OES is developing a study methodology that combines different kinds of commercial software (ASAP™ FlowTherm™ and ANSYS™). The ability to simulate the multi‐physics phenomena is important to the analysis of the image quality for various optical components. This simulation indicates that the cooling system will cause depolarization of the light in the first PBS, which will degrade the contrast ratio of the system.

Published: January 2005

AbstractMaterials selection plays an extremely important role in the performance and aging characteristics of holographic polymer dispersed liquid crystals (HPDLC). A strong dependence of electro‐optic performance and aging properties on monomer functionality is reported. Materials formed with lower functionality monomers exhibited better long‐term optical and drive‐voltage characteristics than those formed from higher functionality monomers. These aging characteristics are linked to different polymer morphologies.

P‐91: Effect of UV‐ozone Treatment as a Function of Time on the Surface Electronic Structure of Indium Tin Oxide
Authors: Kim Soo Young , Lee Jong‐Lam , Kim Ki‐Beom , Tak Yoon‐Heung 
Published: January 2005

AbstractWe report the change of surface electronic structure of indium tin oxide (ITO) as a function of UV‐ozone treatment time. The voltage at the current of 100 mA/cm2 is lowered as a function of UV‐ozone treatment time. It was found that the atomic concentration of carbon decreased, and that of oxygen increased. This leads to the increase of ITO work function via the reduction of turn‐on voltage.

5.1: Invited Paper: High Efficacy PDP
Authors: Oversluizen G. , Dekker T. , Gillies M. F. , de Zwart S. T. 
Published: January 2005

AbstractThe trade‐off between PDP panel efficacy improvement and driving voltages is investigated for several design factors. It is found that for a proper combination of an increased Xecontent, cell design, and the use of a TiO2‐layer combined with “non‐saturating” phosphors, a large increase of both efficacy and luminance can be realized at moderately increased drive voltages. In a 4‐inch color test panel a white efficacy of 4.4 lm/W and a luminance of 5000 cd/m2 is obtained for sustaining at 250 V in addressed conditions.
5.4: Long Gap Discharge Characteristics Based on Control of Voltage Distribution among Three Electrodes for Positive Column AC‐PDPs
Authors: Kim Hyun , Tae Heung‐Sik , Chien Sung‐Il 
Published: January 2005

AbstractThe positive column discharge characteristics in the long gap 440 μm are investigated based on the voltage distribution among three electrodes. In particular, the effects of the amplitude and width of the short pulse applied to the address electrode on the positive column discharge characteristics are examined intensively. By proper controlling of the amplitude and width of the address short pulse, it is found that the positive column discharge in the long gap is well constructed. As a result, under the stable static voltage margin condition, the firing and sustaining voltages are as low as those of conventional short gap60 μm discharge and the color purity is improved. Moreover, the luminous efficiency increases up to 60% in comparison with the conventional case.
