33.2: Image Enhancement in JPEG Domain for Low‐Vision Patients
Authors: Tang Jinshan , Peli Eli 
Published: January 2005

AbstractAn image enhancement algorithm for low‐vision television viewing was developed. The algorithm enhances the images in the JPEG/MPEG domain by weighting the quantization table. The advantages of our algorithm are threefold: (1) Low computation (only a change of the 8×8 quantization table in the decoding stage); (2) Suitable for real‐time application; and (3) easily manipulated by individual users, because the enhancement level can be controlled at the receiver.

Authors: Galanter Eugene , Sachtler Wendelin 
Published: January 2005

AbstractWe describe a method to evaluate color vision deficits in school children via an Internet connection. These deficits, when genetic, occur in about 8% of males, and 1% of females. Environmental factors have also been shown to produce such deficits, although the details are not yet clear. Our corporate evaluation technology requires that validity be preserved independent of calibration errors at the viewers station.

Published: January 2005

AbstractBoth binocular and monocular HMDs designed to be used non‐immersively were found to create minimal interruption of the visual fields making them safe to wear (but probably not to use) in mobile situations. A small opaque display can be positioned to provide a see through functionality.
4.2: A New Blue Phosphor for PDP Applications
Authors: Rao R. P. 
Published: January 2005

AbstractSmall particle thulium activated lanthanum phosphate (LaPO4: Tm3+) phosphor samples are prepared by a solid‐state as well as sol‐gel processes in presence of flux. These phosphors exhibit a narrow band emission in blue region, peaking at 453 nm when excited by 147 and 173 nm radiation from Xenon gas mixture. They also exhibit good color saturation and better stability when excited with VUV radiation when compared with the currently available commercial phosphors such as BAM. The phosphor of present investigation, having uniform and spherical shape particles in the range 0.1 to 2 microns, is appropriate for thin phosphor screens required for PDP applications. To achieve higher brightness, these phosphors are blended with other UV excited blue emitting phosphors such as BAM. Results related to morphology, emission and degradation of these phosphors in the process and operation of plasma display panels are presented and discussed.
P‐1: Dependence of Poly‐Si TFT Characteristics on Oxide Interface Traps and Grain Boundary Traps and its Application to Diagnosis of Fabrication Processes
Authors: Kimura Mutsumi , Abe Daisuke , Inoue Satoshi , Shimoda Tatsuya 
Published: January 2005

AbstractThe dependence of poly‐Si TFT characteristics on the density of oxide interface traps (Dit) and grain boundary traps (Dgb) has been analyzed. The subthreshold swing and threshold voltage mainly depend on Dit, while the transistor mobility depends on Dgb. It is found that oxygen plasma treatment reduces Dit, while plasma‐enhanced chemical‐vapor deposition of tetraethylorthosilicate for gate‐oxide generates Dgb.

Published: January 2005

AbstractWe have developed the five mask PMOS and the six mask CMOS process architecture for poly‐Si TFT. In order to have a competitive process with that for a‐Si TFT, the simple co‐planar electrode structure whose data line electrode and pixel electrode are on the same plane was adopted. In addition, RGB + White four color technology were applied to achieve high aperture ratio and transmittance. Using the aforementioned process architecture and four color technology, 2.0 inch qCIF transmissive micro‐reflectance (TMR) device was successfully fabricated.
P‐4: Investigation on the Correlation between Layout Parameters and ESD Robustness of LTPS TFT Devices
Authors: Chu Fang‐Tsun , Tseng Huai‐Yuan , Chen Chen‐Ming , Chen Cheng‐Chung , Yeh Yung‐Hui , Hou Chun‐Lin , Chang Chih‐Yih 
Published: January 2005

AbstractThe electrostatic discharge (ESD) characteristics and robustness of LTPS TFT devices with different layout parameters were investigated in this paper. Several key layout parameters and device structures, such as device channel length/width, drain contact to gate spacing, contact layout geometry, gate‐overlap structure and LDD length…etc, were designed to characterize the device ESD performance by using both electrostatic discharge simulator (ETS‐910) and transmission line pulsing generator (TLPG) system. The ESD induced failure phenomena were also discussed. These layout dependent results on ESD robustness of LTPS TFTs would help designers implement the ESD protection devices or circuits on the panel of glass substrate.
P‐8: Reliability of Single‐Crystalline Si TFTs Fabricated inside a Location‐Controlled Grain
Authors: Rana V. , Ishihara R. , Metselaar J. W. , Beenakker C. I. M. , Hiroshima Y. , Abe D. , Inoue S. , Shimoda T. 
Published: January 2005

AbstractThe reliability of TFTs (W/L= 2.03/1.87 μm) fabricated inside a grain formed by μ‐Czochralski process was studied under static bias stress. Upon drain stress up to 14V with 300 sec, there was no threshold voltage shift observed. With strong drain bias stress with 14V, however, the initial field effect mobility of 600 cm2/Vs was decreased. The amount of decrease in the mobility decreases with laser energy density for crystallization. Upon positive gate bias stress, transfer characteristics was stable, while, upon negative bias stress, hump appeared in the curve.

AbstractA new active matrix organic light emitting diode (AM‐OLED) pixel design, based on the a‐Si:H TFTs, is proposed and verified by SPICE simulations. The simulation results show that the proposed pixel, which consists of 7‐TFT and 1‐capacitor and 1‐additional signal line, compensates the problem of the threshold voltage degradation in the a‐Si:H TFT and OLED.

A novel off‐axis holographic micro‐diffuser is also discussed.

P‐27: Adaptive Display Color Correction Based on Real‐time Viewing Angle Estimation
Authors: Li Baoxin , Feng Xiao‐Fan , Daly Scott , Sezan Ibrahim , Van Beek Peter , Pan Hao 
Published: January 2005

AbstractWe propose a method for adaptive LCD color correction through manipulating the pixel values to be displayed based on automatically detected viewing angle. The viewing angle detection is achieved through gaze/eye/face detection and tracking in the image/video captured by a camera that is fixed on the display. The proposed approach does not require physical modifications to the LCD display.
P‐28: Image Adjustment with the Tone Rendering Curve
Authors: Vuori Tero , Björknäs Kristina , Oja Joni , Lamberg Markku 
Published: January 2005

AbstractThis paper investigates the suitability of different tone rendering curves (gamma functions) at different external illumination levels and with different display content. It is difficult to find an optimum gamma value because image quality strongly depends on the image content and the external illumination. Tuning the tone rendering curve based on ambient light sensor and / or image content of the display would significantly increase the perceived image quality.
P‐29: Variability in Susceptibility to the Color Flash Effect in Field Sequential Color Displays
Authors: Baron Peter C. , Chase Walter 
Published: January 2005

AbstractWe report on a study to develop population statistics on susceptibility to the “color flash effect” (CFE) a visual artifact observed, to varying degrees, by viewers of field sequential color (FSC) displays. Subjects made saccades across a vertical bright line generated by a simulated Philips “scrolling color” FSC display, judged to be representative in this regard to conventional FSC displays. Pre‐analyzed test data from 32 young adults show that contrast ratio thresholds and luminance thresholds for CFE detection vary over (wide) ranges of log 1.2 (15.9:1) and log 1.07 (11.8:1), respectively. A statistically significant though moderate (0.40) correlation exists between the two thresholds. The results of less rigorous testing of 26 old‐than‐40 year adult indicate that CFE susceptibility is not age‐dependent. The well‐researched perceptual mislocalization of signals flashed during a saccade is identified as the primary cause of CFE.

The microstructure and field emission properties of carbon nanotubes were investigated. Raman spectroscopy results show a strong sp2 peak indicating formation of well‐graphitized carbon nanotubes. The SEM and TEM micrographs show the microstructure of multi‐walled carbon nanotube with the diameter about 5 to 50 nm. From field emission measurement, the low onset field about 1.42 V/μ m can be obtained.

Published: January 2005

AbstractWe have investigated effects of post‐treatment of carbon nanotubes(CNTs) films on field emission characteristics. CNTs films were prepared with Ar plasma treatment of different exposure times. With the Ar plasma treatment, electron emission at low threshold field was observed and higher emission current at 2.9 V/μm was generated, compared to the untreated films. Also the field emission site density of CNTs films was improved by Ar plasma treatment. We show that electrons can be emitted from not only CNT tip but also irradiation‐induced defects on CNTs walls.

Published: January 2005

AbstractThe characteristic of herringbone type carbon nano fiber (HB‐CNF) emitter was described. HB‐CNF prepared by thermal CVD was mixed with binders and conductive materials, and then were formed by screen‐printing process. In order to obtain efficient field emissions, the surface treatment of rubbing & peel‐off was applied to the printed CNF emitters. The basic structure of FED was of a diode type through fully vacuum packaging. Also, we proposed a new field emitter as field emission display.
P‐36: Effects of Binder Materials in CNT Paste on Field Emission Properties for CNT‐Cathode Applications
Authors: Cho Young‐Rae , Choi Woo‐Suk , Shin Hoe‐Young , Ahn Byung‐Gun , Kim Dong‐Hee , Lee Dong‐Gu 
Published: January 2005

AbstractThe effects of binder materials in carbon nanotube (CNT) paste on field emission properties were investigated with respect to high‐efficient CNT‐cathode applications. The binder materials that bond the CNTs to a cathode electrode were composed of an insulating glass‐frit and a conducting Ag‐paste. The dependence of the electrical conductivity of CNT paste comprised of binder material and CNTs ink on the field enhancement factor was investigated using the Fowler‐Norheim equation. CNT films were prepared via a screen‐printing process using the CNT paste. The emission current from the CNT cathode by an electron tunneling effect was increased with increasing ratio of the dielectric glass‐frit fraction in the CNT paste. The reason for the larger emission current from the CNT cathode containing insulating binder materials is due to the increased effective height of CNTs which protrude over the film in the cathode electrode, which effects the field enhancement factor.
P‐37: An Optimized Boost Table Measurement Method for Response Time Acceleration in LCD
Authors: Kim Taesung , Park Bongim , Park Jinhyeok , Berkeley Brian H. , Kim Sang Soo 
Published: January 2005

AbstractA new measurement scheme is proposed to generate an optimized boost table for video rate LCD response time compensation. This method, which closely follows basic theory, enables up to a 90% reduction in the lookup table creation time compared to conventional methods. Furthermore, while conventional approaches require all measurements to be repeated in order to load the entire LUT whenever key parameters such as refresh rate or boost intensity are modified, the method proposed in this paper allows the new table to be calculated by utilizing saved waveform data without the need for any repeated measurements.
P‐44: A study of the Energy Consumption in Bistable Displays and their HV‐Drivers
Authors: Vermandel M. , Doutreloigne J. 
Published: January 2005

AbstractA detailed study of the energy consumption to put an image on a bistable display is presented. For this purpose, general formulae are derived to A) calculate the energy sourced to the capacitive display by the drivers and B) calculate the energy dissipated inside the drivers to make the driver work correctly. It is found that in displays with low image frame rate, the internal power dissipation of standard high voltage drivers due to the required level shifting is much higher than the energy sourced to the bistable display. Using a new driver architecture, based on dynamic charge control, the driver dissipation is reduced with several orders of magnitude. This results in much lower total power consumption, and a dramatic improvement on the operating time in battery powered applications.

HBM and MM ESD robustness of the LCoS with both of low‐voltage (LV) and high‐voltage (HV) ESD protection design can achieve above 3.5kV and 200V. The analysis on I‐V curve shifting of I/O pin shows the ESD damages on the GGNMOS in I/O ESD protection.
LP‐13: Late‐News Poster: A Study of Motion Adaptive CODEC Feedforward Driving without SDRAM
Authors: Someya Jun , Okuda Noritaka 
Published: January 2005

AbstractAuthors have been engaged in the development of a feed forward driving technique, as part of the overdrive technique to improve the response time of liquid crystal displays. They have developed, in particular, a compression feed forward driving system in which an image compression technique was applied, focusing on a method of reducing the frame memory necessary for the signal processing of overdrives. Further, they are now studying motion adaptive CODEC feed forward driving that reduces the amount of overdrive errors by adding a motion‐adaptive process to the image decoding section in cFFD. This paper discusses macFFD that does not use SDRAM as the overdrive for entry model LCD TVs. Setting the image compression ratio to 1/10 or so will enable the fabrication of frame memory for overdrive for SDTV using SRAM.

Published: January 2005

AbstractA carbon nanotube field emission display(CNT FED) panel with a 2 inch diagonal size was fabricated by using a screen printing of a prepared photo‐sensitive CNT paste and vacuum in‐line sealing technology. After a surface treatment of the patterned CNT, only the carbon nanotube tips are uniformly exposed on the surface. The diameter of the exposed CNTs are usually about 20nm. The sealing temperature of the panel was around 390 °C and the vacuum level was obtained with 1.4×10−5 torr at the sealing. The field emission properties of the diode type CNT FED panel were characterized. Now, we are developing a triode type CNT FED with a self‐aligned gate‐emitter structure.

Published: January 2005

AbstractThe crystallization of amorphous metal oxide thin films was achieved by RF plasma treatment. Although various amorphous films are crystallized after 3 minutes or so, the sample temperature is lower than 150 degrees C without compulsory cooling even when the films are treated for 1 hour. The oxygen gas pressure on the plasma treatment was found to be the key parameter on the crystallization. This treatment works on amorphous films of various materials, independently of the film preparation method and substrate materials.

AbstractWe developed a line profile sensor on LCD substrate using the diffraction properties of electromagnetic waves. The sensor can measure the line width and height simultaneously with less than several seconds. The small size of 200mm(W) × 150mm(D) × 250mm(H) makes in‐line installation easy. We analyzed the diffracted beams from LCD substrates, and derived the line profiles experimentally.

Published: January 2005

AbstractThe cold cathode fluorescent lamp (CCFL) with Ar and Xe gases was manufactured and the luminance characteristics were measured under various ambient Temperatures. The luminance of CCFL with Ar + 10% Xe showed higher luminance and luminous efficiency than that of CCFL with Ar gas only. The luminance and the luminous efficiency of CCFL with Ar + 10%Xe were approximately 40% and 8% higher than that with Ar gas only at ambient temperature of 50 °C. It was found that the luminance and luminous efficiency of CCFL can improve by addition of Xe gas.
