Published: January 2005

AbstractThe CL spectrum and relative intensity of Sr5PO43Cl:Eu2+ has been studied with Ca2+ or Ba2+ substitute for Sr2+ into the crystal. With Ca2+ doping increased, the emission peak of Sr5PO43Cl:Eu2+ under electron excitation changed from 445 to 455nm, and the relative intensity of Sr5PO43Cl:Eu2plus; was improved simultaneously. This blue phosphor can be used for emissive display application under mid‐ or low‐voltage.
P‐27: Investigation of the Excitation Functions in the Y2O3: Eu‐Gd2O3: Eu Luminecent System for the Voltage of 300–1000V
Authors: Vorobyov Victor A. , Sinelnikov Boris M. , Kargin Nickolai I. , Siglovaya Natalie. V. 
Published: January 2005

AbstractDependence of luminous efficiency in the Y2O3: Eu‐Gd2O3: Eu solid solutions which are highly promising for application in FED was studied. Their volt‐luminance characteristics have been explained on the basis of the sensibilization effects of the Eu3+ emission with Gd3+ ions and by decrease of the penetration depth of the primary electrons into the phosphor. This allowed to determine a thickness of a “dead layer” and to show its dependence on the phosphor synthesis conditions.

Published: January 2005

AbstractAt present Porous polycrystalline silicon Nano‐Structured PNS emitter shows the relatively high performance with lower turn‐on voltage and higher emission current than the conventional field emitter. But it has still the problem to be solved. Since the Au as a top‐electrode was thermally diffused to thin oxide during the vacuum packaging process, the electrical performance of PNS emitter was decreased by thermal activation energy between the thin firms. In this study, we analyze the changed property of Au using Auger Electron spectrometer AES and Scanning Electron Microscopy SEM. And the property of Au related with the thermal activation energy was discussed with the fundamental diffusion property. From this analysis, we can understand for electron emission property of PNS emitter and made the vacuum packaged PNS emitter.

P‐36: Block‐dim Free Driving Options for TFT Panels with PCB‐less or COG Gate Driver
Authors: Buchschacher Pascal , Daum Martin 
Published: January 2005

AbstractNew low cost assembly techniques for TFT gate drivers GDs use on‐glass track to replace traditional printed circuit board PCB wiring. Row return currents then induce excessive voltage disturbances because the sheet resistance of on‐glass track is roughly 100 times higher than before. TFT panels with storage capacitor Cst on the previous gate line are badly affected when driven by conventional 2‐level GDs. Horizontal gray areas of different intensity block‐dim appear when an asymmetrical pattern is displayed. This paper reviews known techniques to suppress block‐dim and proposes a new solution for standard TFT panels.

Published: January 2005

AbstractWe have made a 42‐inch PDP autostereoscopic three‐dimensional display. A sheet of lenticular lens is placed in front of a 42‐inch PDP of full color XGA. The surface temperature of a PDP can be high during its operating times. The pitch of lenticular lens may be expanded. It makes an undesirable problem of deteriorating the 3D image quality. To overcome this problem, we have developed a 3D simulator to design a lenticular lens properly and measured the thermal expansion ratio of the lenticular lens and the surface temperature of the PDP. These two measured values have been used in the design of lenticular lens.

LP‐2: Late‐News Poster: Investigation and Analysis of a Design for Seamless Tiling of LCD Displays Based on PL‐LCD Architecture
Authors: Mienko M. , Crossland W. A. , Mavaddat R. 
Published: January 2005

AbstractIn this paper we present the aspects of designing a seamless display using tiled Photoluminescent LCD PL‐LCD imaging elements. The method described combines a single LED backlight source, projection and beam shaping optics, LC pixel block and a photoluminescent screen, all of which make up a single element, which then in principle, allows tiling of arbitrary large displays using typical LCDs. Nevertheless, spatial variation in brightness, optical distortion and liquid crystal effects impose system design limitations and also cause front face appearance problems. All of these are reported and possible solutions described.

Published: January 2005

AbstractThe basic discharge characteristics of the coplanar long gap electrodes in an AC PDP were investigated. The luminous efficiency of the 150μm gap coplanar discharge was 3.7 lm/W. The luminous efficiency was decreased drastically when the gap of the coplanar discharge was 500μm. The luminous efficiency of the 500μm gap coplanar discharge was about 4 lm/W when the high frequency pulses were applied to the auxiliary electrode located at the center of two sustain electrode.
P‐57: Effects of Kr Addition on the Discharge Characteristics of He‐Ne‐Xe‐Kr Gas Mixtures in Plasma Display Panel
Authors: Jung E. Y. , Kwon Y. H. , Cho H. D. 
Published: January 2005

AbstractThe effects of Kr addition on the characteristics of the He‐ Ne‐Xe‐Kr gas mixtures were investigated to achieve high luminous efficiency in plasma display panel. The experimental results reveal that the luminous efficiency increased drastically with respect to Kr concentration at fixed applied voltage. The reason for this was considered due to increasing the Kr excimer emission Kr2* and reducing the power consumption. Especially, the luminous efficiency steeply increases at high gas pressure with increasing Kr concentration because the efficiency of Kr excimer Kr2* increases due to three‐body collision at high gas pressure.

P‐60: Reset Waveform for Dark‐Room Contrast‐Ratio Improvement
Authors: Kim Gun‐Su , Choi Hoon‐Young , Park Suk‐Jae , Lee Seok‐Hyun , Seo Jeong‐Hyun 
Published: January 2005

AbstractIn this paper, we propose the new reset waveform which shows high dark‐room contrast‐ratio and robustness for cross talk. We apply a ramp pulse to the address electrode after the erase X ramp pulse. And a constant bias voltage is applied to X electrode during the Y rising‐falling ramp and the address period. Using this method, we achieved a great dark‐room contrastratio 2750:1. However, the address minimum voltage was increased about 17∼37V compared with the conventional ramp reset method. We could reduce the minimum address voltage through the waveform optimizing. As a result, when VSB is −30V, we could reduce the address minimum voltage about 14∼28V and improve the dark‐room contrast‐ratio3000:1.
P‐62: Improvement in PDP Image Quality by Suppressing Dynamic False Contour While Maintaining High Brightness
Authors: Xu Bei Lei , Xie Zheng Cai , Tian Jin Shou , Niu Han Ben 
Published: January 2005

AbstractPlasma display panels PDPs utilize pulse‐number modulation method to realize gradation display. The method usually gives rise to false contour distortion when moving picture is reproduced. To solve the problem, it's common to increase the number of sub‐fields and to optimize the value of weight for each sub‐field. However, with increasing the number of sub‐fields, the percentage of sustain period occupied in a TV‐field decreases, thus the maximum available brightness of image reproduced decreases. We proposed a new method to reduce dynamic false contour without increasing the number of sub‐fields. A TV‐field is divided into a dither‐gradation sub‐field, an interpolative‐gradation sub‐field and several main‐gradation sub‐fields. In each TV field, light‐emitting sub‐fields are successively arranged almost from the beginning of the TV field. Thus dynamic false contour can be substantially suppressed. Moreover, the number of sub‐fields is not increased due to introduction of a dither‐gradation sub‐field and an interpolative‐gradation sub‐field. As compared with the CLEAR method, only approximately half the number of sub‐fields is needed to obtain the same gradations display. Therefore the peak brightness is kept high.

Authors: Kim Oe Dong , Park Jae Bum , Choi Kwang Yeol 
Published: January 2005

Abstract7.5″ AC‐PDPs with closed rib structures were prepared and their pumping characteristics were measured with a spinning rotor gauge. It is found that the pumping characteristics are composed of three different regimes, ‘volume flow’, ‘transient flow’ and ‘molecular flow’. The most time‐consuming regime was ‘molecular flow’. We applied the annealing process and the structural pumping paths that reduced the ‘molecular flow’. It is also found that the pumping characteristics of panels are quite dependent on the existence of the pumping paths when the annealing process is applied.

Published: January 2005

AbstractIn this study, micro‐injection molding process was used in fabricating barrier ribs for the plasma display panels. A paste consisted of ceramic powders for the barrier ribs, binder, hardener, and dispersant was filled into cavities of a polymeric mold by an external pressure. Effects of ceramic powder and curing agent contents, diluent type and content on the viscosity of paste were investigated in order to increase the powder content in the paste. By optimizing the compositions of the paste, the micro‐injection molding pressure could be decreased to approximately 1.5 kgf/cm2 and defect free ribs were formed. The results demonstrated that the micro‐injection molding route is capable of producing barrier ribs of fine pitch.

Published: January 2005

AbstractIn this study, the effects of chemical compositions and inert fillers, such as quartz and Al2O3, on the sintering behavior and physical properties of barrier ribs of plasma display panels were investigated. The sintering of glass frit of compositions of 70PbO‐25SiO2‐5B2O3 was found to be affected significantly by the type of fillers used and their contents. The addition of fused quartz as a filler was found to reduce the sintering temperature as well as to improve the fracture resistance of the barrier ribs.

AbstractIt is well known that panel glass of PDP module can be easily broken when the temperature difference on panel surface is over 20°C. Accordingly, it is necessary to improve heat dissipation of PDP module effectively in order that temperature difference of panel glass may be minimized after electrical discharge takes place between front panel and rear panel. Current heat dissipation scheme for PDP 42″ module consists of panels, chassis and TSSThermal Spread Sheet between panels and chassis. At present research, it is investigated through temperature measurement and numerical simulation how much TSS affects the temperature differences on front panel surface and it is also shown through measurement how much other kind of TSS can reduce both the temperature differences and highest temperature on front panel surface.

AbstractWe have suggested and developed a novel 6 photo‐mask process for the p‐channel poly‐Si thin film transistor TFT panel fabrication of active matrix organic light‐emitting diode AMOLED. By removing power line Vdd and bank photo process, we simplified the fabrication process from 8 to 6 mask steps.
