P‐6: A Novel Self‐Aligned Lightly‐Doped‐Drain Polysilicon Thin‐Film Transistor Using a Partial Exposure Technique
Authors: Xiong Zhibin , Liu Haitao , Sin Johnny K. O. 
Published: January 2005

AbstractIn this paper, a novel self‐aligned lightly‐doped‐drain (LDD) Poly‐Si TFT using a partial exposure technique is proposed and demonstrated. The LDD region is self‐aligned to the channel and with a length ranging from 0.4 μm to a few μm. The different LDD lengths can be obtained simply by different layout designs. The partial exposure technique for obtaining the LDD is simple and effective, and does not require any additional mask. Experimental results show that the on/off current ratio of the LDD Poly‐Si TFT with 0.5 μm LDD length and 5 μm channel length is approximately 12 times larger than that of the conventional non‐LDD TFT.

Authors: Kim Do‐Sung , Kang Byung‐Goo , Choi Woon‐Sub , Soh Hoe‐Sup , Kim Woo‐Yeol , Jung Ki‐Yeol , Lee Hyun‐Kyu , Park Young‐Seok 
Published: January 2005

AbstractWe designed a new pixel layout to improve the aperture ratio of IPS mode TFT‐LCD(H‐IPS). This H‐IPS pixel layout design has reduced the width of side common electrode used to minimize the cross talk and light leakage which is induced by interference between data bus line and side common electrode of conventional IPS mode. The side common electrodes of a pixel can be reduced by horizontal layout of interdigital electrode pattern where conventional IPS pixel designs have vertical layout of interdigital electrodes. We realized 15 inch XGA TFT LCD of H‐IPS structure which has aperture ratio as much as 1.2 times of corresponding conventional IPS pixel design.

P‐10: A Novel Double Pulse Scan Method for Fast Driving of a π Cell
Authors: Lee Jong Lac , Lee Seo Hern , Jhun Chul Gyu , Kim Jae Chang , Yoon Tae‐Hoon 
Published: January 2005

AbstractWe propose a novel driving method which is very effective for the display of moving pictures on a π cell. In the new driving method, we proposed each scan pulse is divided into two parts for fast switching unlike the conventional active matrix driving method that uses one scan pulse for each frame. By overdriving or underdriving the π cell using an appropriate data voltage during the first scan time and applying a desired data voltage to the cell during the second scan time, we can achieve fast switching between all gray levels.
P‐11: An Improved Voltage Programmed Pixel Structure for Large Size and High Resolution AM‐OLED Displays
Authors: Choi Sang‐Moo , Kwon Oh‐Kyong , Chung Ho‐Kyun 
Published: January 2005

AbstractWe propose an improved pixel structure for large size and high resolution AM‐OLED(Active matrix‐Organic Light Emitting Diode) displays. The proposed structure is composed of 5 TFT and 1 capacitor. It can compensate not only the threshold voltage variation of LTPS(Low Temperature Poly Silicon) TFTs but also the voltage drop of supply voltage on panel. Moreover, it operates with simple structure and control signals. In this paper, we describe the operating principle and the characteristics of the proposed pixel structure and verify the performance by HSPICE simulation comparing with those of previously reported structures.

Authors: Shin Moon Young , Han Sang‐Myeon , Lee Min‐Cheol , Shin Hee‐Sun , Han Min‐Koo , Kwon Jang‐Yeon , Noguchi Takashi 
Published: January 2005

AbstractWe have fabricated polycrystalline silicon (poly‐Si) thin film transistor (TFT) at 170°C using inductively coupled plasma chemical vapor deposition (ICP‐CVD) and excimer laser annealing (ELA). A Poly‐Si film with large grains exceeding 3000Å and a SiO2 film with N2O plasma pre‐treatment in order to reduce the oxide charge densities as well as to increase the breakdown field are deposited by ICP‐CVD. Our experimental results show that the proposed treatment improved the flat‐band voltage from −3V to −1.8V. The proposed treatment also improved poly‐Si TFT characteristics such as low sub‐threshold swing of 0.43V/dec.

P‐16: A New Driving Method to Compensate for Row Line Signal Propagation Delays in an AMLCD
Authors: Kim Soo Hwan , Kim Gyoung Bum , Kim Suk Ki , McCartney Richard I. 
Published: January 2005

AbstractThe distributed capacitive and resistive nature of both the row and column lines in an AMLCD introduces significant propagation delays to their respective addressing signals. The row signal delay is conventionally accommodated by shortening the row select time, which requires lower TFT on‐resistance to provide adequate charging ratios of the pixels. We present a new approach to column driving which results in a much‐improved pixel‐charging ratio. The benefit is of particular interest to large‐area, high‐resolution, wide‐aspect‐ratio, LCD TVs.
LP‐1:Late‐News Poster:Development of a Novel Transflective‐Type VA‐LCD
Authors: Koma Norio , Mitsui Masashi , Inoue Kazuhiro , Maeda Kazuyuki , Yamada Tsutomu , Tanaka Yoshiki 
Published: January 2005

AbstractWe propose a novel transflective‐type of vertical alignment liquid crystal display (VA‐LCD) that adopts a new direction control method and an RGB multi‐gap structure. The shape of the pixel electrodes and the direction control projections are optimized to decrease disclination lines with fixation, and higher transmittance and reflectance are obtained. In addition, the RGB multi‐gap structure results in excellent voltage‐chromaticity characteristics at a low driving voltage. We also propose a process for producing this LCD.

P‐20: Antireflection Systems for Flat Panel Displays ‐ an overview
Authors: Boerner Volkmar , Kübler Volker , Bläsi Benedikt , Gombert Andreas 
Published: January 2005

AbstractThe design of the front surface of a display, the interface to the viewer, requires careful selection of materials and coatings. The most prominent requirements for the front surface material are reflection or glare treatment, scratch resistance and of course a good optical appearance. Different types of optical films and coatings are available with different types of antireflection systems. This article gives an overview over available antireflection (AR) systems and compares their performance and their limitations. The comparison covers interference AR coatings made by thin film deposition either by evaporation or from liquid phase (sol‐gel), single and multilayer thin film systems, graded index profile systems (porous and motheye), antiglare (AG) and combined AG/AR systems.

Published: January 2005

AbstractThermostimulated luminescence and brightness decay of low‐voltage cathodoluminescence in the conditions of dynamic and static vacuum for the ZnO:Zn and ZnO:Zn, Si have been studied. At low anode voltages the thermostimulated luminescence (TSL) peaks conditioned by gas adsorption on the phosphor surface were recorded. It is shown that the adsorption ability of ZnO:Zn, Si is lower than that in ZnO:Zn which is the reason for a longer service of a modified phosphor. The model of the modifying coating action is being considered.

Published: January 2005

AbstractActive‐matrix field emission display (AM‐FED) with a glass‐mesh gate plate was developed by using single‐wall carbon nanotube (CNT) as an electron emission source and a‐Si TFT as a control switch, respectively. The a‐Si TFT and screen‐printed CNT emitters were successfully integrated to fabricate the active‐matrix cathode. We fabricated the first prototype AM‐triode CNT FED panel with 5‐in. in diagonal and 160×3×120 subpixels through the vacuum packaging of the AM cathode, the glass‐mesh gate, and the anode. The fabricated AM‐CNT FED panel showed good uniformity, high stability and reliability, and high brightness with a driving voltage of below 15 V.

Authors: Hsu C. H. , Shen Y. R. , Chen C. J. , Chien L. C. , Ho H. J. , Wong Y. J. 
Published: January 2005

AbstractIn this paper, we report an advanced anti‐double edge overdriving method. This method overcomes artifacts from conventional overdriving schemes, such as double edge artifact, overshooting and undershooting. New artifacts also are reported and photo to explain the performance of our new algorithm. Edge oscillation artifact is reported in the paper for the first time. As we strongly overdrove the conventional feed backward overdriving method, these new artifacts occurred. Our advanced anti‐double edge overdriving method successfully eliminates these artifacts and overdrives the spec of grayscale response to less than one frame time. IPS, MVA and fast TN LCD panels are all evaluated from commercial monitor to TV products by our new driving method. 8 ms grayscale switching performance over exact 8 bit to 8 bit transition can be achieved at 60 Hz frame rate.
P‐42: One Point Color Tracking Method for High Definition Flat Panel Display

Published: January 2005

AbstractSerious color shift problem at different grayscales is an intrinsic characteristic in liquid crystal display. It is induced by gamma‐dispersion and hardware limitation of liquid crystal and display structure. The poor color reproduction becomes heavy burden for system maker to achieve high image quality. Many researches have been reported to improve gray level color temperature by color tracking. As we know, keeping small deviation of correlated color temperature (CCT) from white to dark levels doesn't guarantee high quality of color appearance. The variation of chromatic coordinate at different grayscales must be taken into consideration. In this paper we developed a new algorithm to balance these two factors. We called it One Point Color Tracking (OPCT). The performance for different type LCD (TN, IPS, and MVA) is reported.
P‐43: Image Processing Applied to Small Format Displays
Authors: Oberoi Anirudh , Lillie Jeffrey S. 
Published: January 2005

AbstractThe application of TFT displays for handset applications requires new display system architectures to have on‐chip image processing in order to accommodate a direct camera connection. Other image processing techniques like stochastic dithering are required to reduce the size of the on‐chip frame buffer thus reducing power and silicon real estate utilization, while preserving high image quality. The purpose of this paper is to explore the applicability of certain key image processing techniques, which add value to display column drivers with respect to their typical usage. The benefits and caveats of these image processing methods with respect to power and system bandwidth are articulated and their hardware requirements are discussed.
