Authors: Yamakawa S. , Yabuta S. , Ban A. , Okamoto M. , Katayama M. , Ishii Y. , Hijikigawa M. 
Published: January 2005

AbstractWe have investigated the effect of plasma treatment after a back channel etching process of a‐Si:H thin film transistors (TFTs). O2, N2 and He plasma treatments were done and compared. It was found that the He plasma treatment was the most effective method to decrease the off leakage current in the lower subthreshold region. The He plasma treatment affects the interface characteristics between the a‐Si:H layer and the passivation layer, and obstructs the electron transport near the back channel interface.
A High Performance Bi‐Directional Super‐MIM Diode with Symmetrical and Shift‐Free I‐V Characteristics
Authors: Zhang Shengdong , Sin Johnny K. O. 
Published: January 2005

AbstractA novel self‐aligned bi‐directional MIM (Metal ‐Insulator‐Metal) diode with transparent junctions is proposed and fabricated. The MIM diode is formed by a combination of Ta/TaOx/ITO/TaOx/Ta. In this structure, both symmetrical and shift‐free I‐V characteristics are obtained. The symmetrical I‐V characteristics are attributed to the excellent symmetry in the diode structure. The significant reduction on the shift in the I‐V characteristics is a result of the removal of the charges captured by the traps in the TaOx layers and at the interfaces between the TaOx and the electrodes during electrical stress. Only three masks are needed for the fabrication of the MIM diode pixel, which is as simple as the conventional approach. Moreover, the adoption of the lateral junction approach in the structure makes it possible to be used for high density MIM matrix implementation over large area substrates without the need of high resolution patterning techniques.

Monte Carlo Modeling of Glare in Cathode‐Ray for Medical Imaging
Authors: Badano Aldo , Flynn Michael J. 
Published: January 2005

ABSTRACTThe luminance range of cathode‐ray tube (CRT) systems is limited by glare associated with light diffusion in the thick glass faceplate. This is of particular concern in medical imaging applications, where images with wide luminance range and low contrast detail are displayed. To achieve the required display quality, careful control of the light transfort processes in the faceplate of CRTs is needed. In this paper, an optical Monte Carlo simulation code (DETECT‐II) for modeling the luminance spread in the CRT emissive structure is described. Using this approach, the effect of rough surfaces and anti‐reflective thin‐film coatings on luminance spread functions is examined

Published: January 2005

AbstractA new method for producing high performance AR films at reasonable costs has been developed. This new approach can produce anti‐reflection films with a photopic reflectance of less than 0.8% while providing 3H scratch hardness and steel wool rub resistance. Good anti‐finger print performance is combined with an excellent ability to clean with any of the standard cleaning agents. This technology allows a range of “cost effective” AR products to be made commensurate with the application.

Authors: Dmitrienko A. O. , Nikishin N. V. , Dmitrienko V. P. , Bukesov S. A. , Kim J. M. 
Published: January 2005

AbstractCathodoluminescence of the blue phosphor based on Li‐substituted ZnGa2O4has been studied. The luminance, efficiency, and spectrum of CL at excitation energies 100–600 eV were measured.A blue (Li0.5Ga0.5)0.5Zn0.5Ga2O4phosphor was synthesized. Replacement of half zinc atoms by lithium and gallium atoms leads to an increase in CL efficiency up to 0.2 lm/W. Although them intrinsic luminous efficiency of the blue phosphors in the system ZnO−Ga2O3−Li2O was found to much lower than ZnS:Ag,Cl, the higher resistance to saturation of the oxide phosphor demonstrated that it may be desirable to use this phosphors for low voltage VFDs and FEDs operating at high current densities. The blue gallates are also more attractive for FEDs since its oxide‐based matrix should result in improved life time properties.

Authors: Park Hun‐Gun , Lee Seok‐Hyun 
Published: January 2005

AbstractThe luminous efficiency improvement is one of the most important part to make PDP into leader of large flat panel display device. So, We suggest new type of three component gas, Ne‐Xe‐Ar, to achieve high luminous efficiency of color PDPs. The density of 26 species and electron temperature were calculated by zero dimensional simulation, and we verified a simulation by measuring vacuum ultraviolet, from 140nm to 180nm, in order to find the optimal mixing condition of Ne‐Xe‐Ar gas in color plasma display panel. The maximum peak point of Xe*(1S4 state) state is obtained in 0.5% of Ar mixing ratio by simulation and the maximum luminous efficiency is measured at a point of 0.5% Ar mixing ratio in VUV measuring. The luminous efficiency has been improved considerably (about 30%) by adding Ar (0.5%), compared with Ne‐4%Xe mixing gas.

Published: January 2005

AbstractThis panel has positive column cells with 0.57 pitch in mean. Ceil numbers are 192 in row and 320 in column. A cell has a cathode faced perpendicular to the discharge pass which is parallel to the front and rear glasses. Phosphors are deposited on back side only then luminous efficiency is 0.4 lm/W. But 30 cells with wall phosphor shows 1.0 lm/W. The life is estimated about 50000 h. A TV picture is displayed on the panel by DC mode memory scheme which has no sustain pulse. A vertical contamination removing method in the DC memory is proposed. We show quantitatively dynamic false outline in the DC memory and if we use Kaji s scanning method the false outline is removed.

Authors: Kim Young‐Sik , Lee Yun‐Hi , Ju Byeong‐Kwon , Sung Man‐Young , Shin Dong‐Ki , Oh Myung‐Hwan 
Published: January 2005

ABSTRACTInterface roughness effects in ITO‐Ta2O5‐ZnS:Pr,Ce‐Ta2O5‐Al structures were investigated as a function of thickness of dielectric layer. Internal charge‐phosphor field (Qint‐Fp) analysis and capacitance‐voltage analysis(C‐V) showed that the steady state phosphor field is more smaller and C‐V curve in transition region less steeper with increasing root‐mean‐square‐roughness between dielectric and phosphor layer. The experimental results demonstrate that interface roughness is one of the physical factors to change the electrical performance of ACTFEL devices.

Published: January 2005

AbstractWe have successfully demonstrated light emission from bilayer devices based on polymeric/inorganic heterojunction. In comparison with single polymer diodes, the brightness and luminescence efficiency of bilayer device improved 14 times and 26 times respectively under 10V dc. The EL spectrum of bilayer device shifts continuously as the applied voltage increase. The shift is ascribed to the superposition of emission from polymer layer and inorganic layer.

Authors: Wu Cheng‐Ko , Ko Fu‐Jen , Shieh Han‐Ping. D. 
Published: January 2005

AbstractA new depixelization technique using diffractive gratings to suppress the “discrete” nature of liquid crystal projection image is described. The diffractive gratings transform light emitting from each pixel of an LC panel into mainly 0‐th and 1‐st diffraction order light beams of the equal energy. By deflecting the 1‐st order beams horizontally to 3/2 amount of sub‐color pixels to fill the dead space between each pixel, thus doubling the number of pixels within the image, the image quality of the LCD projection is improved.

P‐64: UV‐Light‐Modified Polyimide Films for Liquid‐Crystal Alignment
Authors: Gong S. , Kanicki J. , Ma L. , Zhong J. Z. Z. 
Published: January 2005

AbstractInfrared, UV‐visible and X‐ray photoelectron spectroscopy measurements indicate that bond‐breaking and oxidation occur during broadband UV‐illumination of the polyimide film in the air. Surface tension and polarity are increased based on the measurements of contact angles. No obvious morphology change has been observed through atomic force microscopy analysis. While the polarized UV‐light generates a relatively small pretilt angle on a nonrubbed surface, it reduces the pretilt angle to some degree on a rubbed surface, depending upon the UV‐light polarization direction relative to the rubbing direction.
