P‐66: High Deposition Rate Technique of Magnesium Oxide Thin Film in Oxide Mode for Plasma Display Panel Applications
Authors: Choi Young Wook , Kim Jeehyun 
Published: January 2005

AbstractA high rate deposition sputtering process of magnesium oxide thin film in oxide mode has been developed using a 20 kW unipolar pulsed power supply. The power supply was operated at a maximum constant voltage of 500 V and a constant current of 40 A. The pulse repetition rate and the duty were changed in the ranges of 10 ∼ 50 kHz and 10 ∼ 60 %, respectively. The deposition rate increased with increasing incident power to the target. Maximum incident power to the magnesium target was obtained by the control of frequency, duty and current. The deposition rate of a moving state was 9 nm m/min at the average power of 1.5 kW. This result shows higher deposition rate than any other previous work of reactive sputtering at the oxide mode. The thickness uniformities over the whole substrate area of 982 mm × 563 mm were observed at the processing pressure of 2.8 ∼ 9.5 mTorr. The thickness distribution was improved at lower pressure. This technique is proposed to apply high through‐put sputtering system for plasma display panel.

Authors: Oh Sang‐Soon , Park Do‐Young , Chang Tae‐Jeong , Kim Yong‐Seog 
Published: January 2005

AbstractIn this study, a reflection layer on rear plate of plasma display panel (PDP) was formed via osmotic coating process in an attempt to improve luminance efficiency of PDP. The processing parameters of the osmotic coating process which include coating solvent, swelling characteristics, and coating time were optimized to obtain uniform reflection layer on inside walls of discharge cell. The effect of TiO2 reflection layer thickness on luminance of the panel was investigated. Comparison with the panel without the layer showed that luminance and its efficacy could be improved by 50%.
P‐69: Luminance and Luminous Efficiency of AC PDP with Coplanar Long‐Gap and High Xe Content Gas‐Mixture
Authors: Park Sang Dae , Shin Nam Hoon , Lee Jae Hyun , Shin Bhum Jae , Choi Kyung Cheol 
Published: January 2005

AbstractThe luminance and luminous efficiency of Ne + Xe gas mixture in an AC PDP were investigated as a function of sustain gap according to Xenon concentration. The discharge characteristics of Ne+13%Xe gas‐mixture were compared with those of Ne+4%Xe when sustain gap was varied and the height of barrier rib was fixed. The luminance of Ne+13%Xe gas‐mixture discharge increased with an increase in sustain voltage until sustain gap was 300μm. The luminance and luminous efficiency of Ne+13%Xe gas‐mixture discharges in 500μm sustain gap were much lower than those in 80∼300μm sustain gap.

Published: January 2005

AbstractThis paper proposes a cross‐shaped cell structure employing an auxiliary address pulse driving scheme for the high luminous efficiency of AC‐PDP. The discharge characteristics of the conventional stripe‐type and cross‐shaped cell structures are compared under a sustain driving frequency of 50 kHz in the 6‐inch test panel with a pressure of 450 Torr and a 10 % Xe‐content gas mixture. The cross‐shaped cell structure shows a higher luminous efficiency than the conventional stripe‐type cell structure in conventional driving scheme. As result of adopting an auxiliary address pulse driving scheme, the luminous efficiency of the cross‐shaped cell structure increases by about 44 % (2.38 lm/W) than that of the conventional case (1.64 lm/W) under 10 % Xe partial pressure.
P‐75: A New Address‐While‐Display Driving Method for AC PDP Using a Dual RMSP (Ramp biased Multiple Short Pulses) Erase Scheme
Authors: Kim Jae‐Sung , Yang Jin‐Ho , Whang Ki‐Woong 
Published: January 2005

AbstractWe propose a new Address‐While‐Display driving method that is composed of an address period, sustain period and erase period only. Instead of the reset period, we used a new erase pulse waveform using a dual RMSP (Ramp biased Multiple Short Pulses). The dual RMSP erase pulse minimizes the wall charge difference between the ON and OFF cells by erasing the wall charge not only between the scan and sustain electrodes but also between the scan and address electrodes in the ON cells. When a thin MgO layer is coated on the phosphor layer, it enlarges the common operating voltage range in all color cells. As a result, 20V dynamic voltage margin and a real black image could be obtained.
P‐78: Enhanced Photoluminescence of BaZr(BO3)2:Eu3+ with Incorporation of Al3+ and La3+ Ions for PDP Application
Authors: Tian Lianhua , Mho Sun‐Il , Yu Byung‐Yong , Pyun Chong‐Hong 
Published: January 2005

AbstractThe photoluminescence (PL) and vacuum ultraviolet (VUV) excitation properties are studied for BaZr(BO3)2:Eu3+. The excitation spectrum shows strong absorption in the VUV region with an absorption band edge at 200 nm. The charge transfer excitation band of Eu3+ at ca. 226 nm is enhanced by codoping Al3+ ion into the BaZr(BO3)2 lattices. The band gap absorption is enhanced by codoping La3+. The PL spectrum shows the strongest emission at 615 nm in BaZr(BO3)2:Eu3+, which results in a good red color purity. The luminescence intensity is enhanced by codoping with Al3+ and La3+.

Published: January 2005

AbstractSpherical, sub‐micrometer Y2O3:Eu and Cubic (Y2‐(x+y)Gdx)O3:Euy3+ (where x = 0.02 to 0.40, y = 0.04) phosphor particles have been synthesized by a novel solution method. These phosphor particles will be ideal for FED devices as they can densely close‐pack on screens and they display high efficiency under low voltage electron beam excitation. It is shown herein that spherical phosphor powder particles can be useful in voltage ranges up to 5000 V and it is also shown in this work that cubic‐Y2O3:Eu particles (ca. 300 nm) perform well at such voltages.

Published: January 2005

AbstractThe properties of SrTiO3:Pr3+:Al luminescent structure under the photoexcitation are investigated. The excitation spectra of luminescence and photocon‐ductivity are obtained. The relationship between the luminescence intensity and concentration of coactiva‐tor (Al) is explored. It is shown, that two centers of luminescence in the strontium titanate are formed. It can be explained by different location of praseodymium ions in the SrTiO3 host lattice (Pr3+ substitutes Sr2+ and Pr3+ substitutes Ti4+).

Authors: Molchan I. S. , Smirnov A. G. , Labunov V. A. , Gaponenko S. V. , Lutich A. A. , Lambertini V. , Repetto P. 
Published: January 2005

AbstractWe report on the developed fabrication method of lanthanide‐doped xerogel/porous anodic alumina structures for an image formation via the aluminum anodization, the sol‐gel synthesis, and the photolithography process. The mechanisms responsible for strong lanthanide luminescence in the structures are discussed. It is speculated that exploiting porous anodic alumina causes significant change in the excitation conditions of lanthanides, probably due to multiple scattering and interference of the exciting light. The structures of europium‐ or terbium‐doped xerogel/porous anodic alumina are also considered in view of application in electroluminescent devices.

P‐91: TFT Substrate Birefringence Induced Asymmetrical Viewing Angle and Compensation Methods
Authors: Ong Hiap L. , Woodard Ollie , Li Shu 
Published: January 2005

AbstractThin‐film transistor (TFT) processes for small pixel geometries can induce optical birefringence effects and change the viewing angle from symmetrical to asymmetrical. We experimentally identified the TFT substrate as the source of the birefringence and developed four methods to compensate the added optical birefringence effects to restore the symmetrical viewing angle. We also developed two special wide viewing angle polarizers with Fuji Film wide viewing angle film, and special compensation films to compensate the TFT substrate's birefringence.

AbstractWe developed a new device structure using anisotropic phase separation from liquid crystal (LC) and polymer composite materials using UV intensity variation and polymer wetting properties. In the device, the LC molecules are isolated in pixels where LCs are surrounded by the inter‐pixel vertical polymer walls and the horizontal polymer films on the upper substrate. These devices show very good mechanical stability against external pressure. The electro‐optic characteristics and the mechanical stability of the devices are discussed in view of the flexible display applications.

AbstractWe have already proposed the In‐plane switching Twisted nematic (IT) mode. The IT mode can provide the wide viewing angle characteristics. However, the IT mode requires high electric field to obtain high contrast ratio. To improve this problem, we propose two kinds of methods as solution. The conventional IT mode is normally white mode, while the proposal IT mode is normally black. In this paper, the suggested these methods and its performance are evaluated.

Published: January 2005

AbstractWe have developed a novel transflective TFT‐LCD with two hybrid aligned nematic compensators (NH film). Already we have presented the wide‐viewing angle transflective TFT‐LCD with one hybrid aligned nematic compensators. Based on the results of computer simulation, we introduced the second NH film, which located on the front of the LC cell, instead of the uniaxial film. We optimized the parameters of NH films, the retardation and the average tilted angle, by computer simulation. As the result, the newly developed TFT‐LCD with two NH films (retardation Δnd = 100nm, average tilt angle = 20degree) is viewable at wider angles than that with one NH film in transmissive mode. Viewing angle range (CR >10) of this LCD, reached 145 degree (vertical direction) and over 160 degree (horizontal direction). This wide‐viewing angle system can apply to not only transflective TFT‐LCD, but also ordinary transmissive one.

AbstractEfficient and low‐voltage top‐emitting OLED using surface‐modified Ag anode is reported. By inducing a thin silver oxide at the surface of Ag, hole injection from Ag anodes into OLEDs is largely enhanced yet with rather high reflectivity retained. Top‐emitting devices using such surface‐modified Ag anode show device characteristics competitive with those of a bottom‐emitting device using the indium tin oxide anode.

AbstractFor a thin film (< 1 μm) encapsulation stack consisting of only 3 plasma deposited silicon nitride layers separated by a thin (< 100 nm) organic layer, a water permeation rate of below 10−5 g/m2 per day at 50 °C and 50% rH has been measured using the Ca test. PLED lifetimes of over 500 hours at 60 °C and 90% rH have been reached locally. While the Ca test indicates that pinhole free encapsulation is possible, edge and particle related defects still forecast a challenge for device encapsulation.

Published: January 2005

AbstractIt is generally recognized that hole‐transport layers (HTLs) with thickness on the order of tens nanometer are indispensable to high luminance and quantum efficiency in small molecule organic light‐emitting diodes (OLEDs). However, in this work, without conventional HTLs, a thin polytetrafluoroethylene (Teflon) layer was introduced as hole‐injection layer, followed by deposition of an emissive layer (EML), Alq3 doped with 0.7wt% DMQA. And simultaneously, a blocking and electron transport layer of aluminum (III) bis (2‐methyl‐8‐quinolinato) 4‐phenylphenolate (BAlq) ETL was employed to confine holes and excitons in Alq3 layer. The obtained OLEDs exhibited a luminance of over 88000 cd/m2 and external quantum efficiency of 5.4% (21.1 cd/A) at voltage of 19.8 V and current density of 418 mA/cm2. When the Teflon thickness was 10.0 nm under our conditions, well‐balanced charge injection could be obtained in OLEDs. It was also found that the high performance was related to triplet‐triple annihilation, in which triplet excited tris (8‐hydroxyquinoline) aluminum (3Alq3*) excitons go through annihilative reactions with other 3Alq3* excitons to form singlet excited molecules. It provides a new way of obtaining highly efficient and stable OLEDs with well‐balanced charge injection.

Authors: Richter A. M. , Keil D. , Diener G. 
Published: January 2005

AbstractThe variation of the structural elements in donor‐acceptor substituted polyenes 1 (A1 = A2 = CN, R1 and R2 form a cyclohexene or pyrane ring, D is an amino substituted phenyl or thiophene ring) influence very much their thermal, emissive and photo‐electronic properties. The contribution shows that the emission can be varied from 630 nm to almost 714 nm. The performance data in a typical device are given and discussed in detail. The substitution pattern influence the thermal properties of the dyes 1 as well. Just by introduction of F‐atoms in the cyclohexene derivatives the thermal behaviour can be influenced very positively, which is of particular interest for the technical use of the dyes.

AbstractWe have successfully synthesized a new blue host material, 2‐methyl‐9,10‐di(2‐napthyl)anthracene (MADN) which is highly stable in thin‐film morphology comparing to the archetypical 9,10‐di(2‐napthyl)anthracene (ADN). When doped with 2,5,8,11‐tetra(t‐butyl)perylene (TBP) as blue emitter in organic light emitting device (OLED), MADN shows an improved EL efficiency of 4.4 cd/A and 2.2 lm/W at 20 mA/cm2 and 6.3 V with a CIEx, y coordinate of (0.14, 0.20). The blue device is stable with an extrapolated t1/2 ∼5000 h at an initial brightness of 880 cd/m2.
36.1: Invited Paper: The Evolution of Flat Panel Cathode Ray Tubes
Authors: Seats P. , Gnade B. 
Published: January 2005

AbstractEver since the rise of television after WWII, display engineers have pursued techniques to shorten cathode ray tubes (CRTs). After reducing neck lengths and increasing deflection angles to a practical maximum of about 110°, the main directions were towards flat panel designs.Typically, these involve the provision of a phosphor coated front plate (anode) sealed to a backplate that is spaced a short distance away. The space between the two plates contains a current source (cathode) and a means to modulate, direct, and accelerate electrons toward the phosphor screen. Designs that have been pursued generally fall into three categories; 1) involving a single beam requiring full deflection in both x and y axes, 2) hybrid designs incorporating multiple beams in one axis combined with electron beam deflection in the second axis, and 3) a fixed x‐y matrix requiring no beam deflection.

AbstractA new concept for analysis of operational characteristic of ac‐PDP is proposed in this paper. The physical state of ac‐PDP cell is defined in terms of wall voltages, which can be traced through the various stages of PDP driving sequence. The voltage domain analysis in combination with firing voltage measurement identifies the cell state and allows the estimation of wall voltage difference between two different cell states. Firing voltage measurement also presented invaluable information on the gas discharge characteristics of ac‐PDP.
