P‐118: The Scanning Electron‐beam Devices based on Electron‐beam‐pumped Semiconductor Lasers for Projection Display Systems
Authors: Sadchikhin A. V. , Sozinov S. B. , Kozlovsky V. I. 
Published: January 2005

AbstractExperience in developments of the laser scanning devices on basis of laser cathode‐ray tubes (CRT) — quantoscopes is summarized. The study results concerning high spatial resolution and high light output of laser CRT projection system are included; the spatial resolution is nearly 3000 TV lines and more, the light output is 10000–15000 Lm. Such high performance attributes of laser CRT projection systems will allow solving the problem of silver‐free information carriers with the image quality comparable with that attained on a 70‐mm cinema film. Improving the quantoscope light divergence by modifying the electron beam profile is considered also. It will allow creating the super‐high resolution laser projection displays and the laser scanning microscopes. Design approach of the main technical questions such as effective cooling system and dry high voltage power supply are presented. The prospects of using the epitaxy technology in the laser CRT target production are discussed.

P‐122: A Novel Wire Grid Polarizer
Authors: Kuo Hui‐Lung , Chiu Chih‐Ho , Chen Pin‐Cheng 
Published: January 2005

AbstractA new wire grid polarizer is made through a series of nanofabrication steps. The visible light polarization effect will occur when natural incident light interact with the novel double layers metal nano‐grating structure on the surface of said polarizer. It gives very high extinction ratio and also no angular dependency. Theoretically, even the incident angle is over 75°, it still possible to give polarization extinction ratio over 5000:1. The feature sizes of the nano‐grating structures have major influence to the polarization states of the reflective and transmitting light. The materials compose the nano grating structure and the morphology also affects the polarization effect. A 5mm × 5mm sample was made and the results will present in this paper.

AbstractThe evolutionary path of increasing the deflection angle in order to reduce the depth of wide‐screen CRTs runs into severe difficulties beyond deflection angles of 120°. We show that transposing the scan direction alleviates most of the difficulties, and enables super‐slim CRTs with deflection angles up to 135°.

Published: January 2005

AbstractThis paper describes an advanced digital display that we have developed for future mobile applications. The 2″ QVGA LCD display contains multi‐format digital drivers integrated with a low‐temperature Continuous Grain Silicon TFT process. These drivers automatically configure the display format based on the contents of the image data that is transmitted to the panel. This strategy provides an optimum balance between display performance and power consumption.
37.3: Analysis of Addressing Characteristics Relative to Cell Dimension and Driving Waveform in AC‐PDP

Published: January 2005

AbstractDynamic behavior was investigated relative to the address electrode width and its misalignment for pulse‐reset and ramp‐reset waveforms and then compared with simulation results. Whereas, the turn‐on voltage showed a decreasing trend with an increasing sustain voltage in a pulse‐reset driving waveform, it remained basically unchanged under the same conditions in a ramp‐reset driving waveform. With an increasing address electrode, the width turn‐on and mis‐addressing voltage had lower values because of the distribution of a larger wall voltage on the dielectric surface of the scan electrode.In addition, it was found that the turn‐on voltage became lower with a decrease in the misalignment of the address electrode. This was because the more the address electrode approached the center, the more the distribution of the wall voltage increased on the dielectric surface of the scan electrode. Finally, the trend of the addressing voltage was quite different relative to the type of driving waveform.

Published: January 2005

AbstractWe have developed a new MVA‐LCD with fast gray‐scale response characteristics. The newly designed jagged shaped pixel electrodes give the oblique electric field and effectively control the LC alignment not only statically but also dynamically. We have realized the response time of 30ms (1/3 of the conventional MVA) for any gray‐scale switching keeping other advantageous characteristics same; CR, viewing range etc.
41.2: Judder‐Induced Edge Flicker in Moving Objects
Authors: Larimer James , Gille Jennifer , Wong James 
Published: January 2005

AbstractThe threshold motion rates that produce edge flicker were determined as a function of contrast, luminance and sampling frequency. A passive filtering scheme, called the Movieola filter, appears to mitigate this artifact. The Movieola filter produces interpolated frames based on a passive two‐tap discrete dissolve. It is simple to implement and therefore relatively inexpensive to manufacture.
41.5L: Late‐News Paper: LCDs: How Fast is Enough?
Authors: Lee Baek‐woon , Sagong Dongsik , Jeong Gyuha 
Published: January 2005

AbstractThe switching speed has become critical once again for LCDs to enter the TV market. In this report, three motion artifacts resulting from the slow response are identified: decrease of dynamic contrast ratio, stroboscopic motion, and blurred edge. It is shown that the first two artifacts disappear completely when the response time is less than 1 frame. However, moving edges cannot maintain the sharpness even if the switching speed is infinite, due to the nature of the hold‐type displays. We show that when LCDs response within half a frame, the quality of moving images is almost as good as that of zero‐response time LCDs. Employing response‐overshoot can enhance the image quality even further.
42.1: A New Electron Gun for a 32″ Super Wide Deflection Angle (120°) CRT
Authors: Bae Mincheol , Song Yongseok , Hong Younggon , Kwon Yonggeol , Lee Kwangsik 
Published: January 2005

AbstractA new electron gun for a super wide deflection angle (SWDA) cathode ray tube (CRT) has been developed. For a SWDA the dynamic focus voltage is usually very high, lowering the dynamic focus voltage is one of the key factors to realize wide angle CRTs. We designed a new quadrupole lens for the electron gun. As a result, we were able to achieve a reasonable focus quality with low dynamic voltage that is comparable to the conventional CRTs. The new electron gun enabled SWDA CRTs possible.

43.4: Address Time Reduction in PDPs by means of Partial Line Doubling
Authors: Hoppenbrouwers J. , van Dijk R. , Holtslag T. , Laffargue F. 
Published: January 2005

AbstractThis paper describes a technique, called Partial Line Doubling (PLD), that reduces the over‐all addressing time of PDPs. This reduction goes at the cost of vertical resolution but the picture quality deterioration is minimised by using appropriate video processing algorithms. The resulting time gain can be used to increase the peak white level of the PDP and/or add extra subfields.
44.1: Invited Paper: New Approaches to Process Simplification for Large Area and High Resolution TFT‐LCD
Authors: Hong MunPyo , Roh Nam‐Seok , Hong Wan‐Shick , Chung Kyu‐Ha 
Published: January 2005

AbstractNovel process architectures are proposed for fabricating large area, high resolution TFT‐LCD's with a minimal number of process steps. A low contact resistance between Al bus lines and transparent conductive oxide layer, necessary for large‐area panels, is obtained by inducing a self‐formed, inter‐metallic compound layer at the interface without using any additional buffer or capping layers. For enhanced brightness and resolution, a new TFT array structure integrated on a color filter substrate, named Array on Color Filter (AOC) structure, has been developed. Good quality TFT's are successfully constructed on the newly developed color filter for AOC within a sufficiently wide process margin. By adopting these novel technologies, a 17.0″ SXGA prototype panel is fabricated and shows good display performance.
9.5L: Late‐News Paper: Overdrive Method for TN‐mode LCDs—Recursive System with Capacitance Prediction ‐
Authors: Sekiya Kazuo , Nakamura Hajime 
Published: January 2005

AbstractOverdrive reduces response time between gray levels of a TFT‐LCD to a single refresh duration. Popular charge‐compensational driving is not sufficient for TN‐mode. With simulation, we found that problems in overdrive including overshoot are caused by the delay of brightness change from capacitance change. An appropriate overdriving circuit is proposed.

46.2: Method to Improve Contrast in an Off‐Axis Projection Engine
Authors: Bone Matthew 
Published: January 2005

AbstractPolarization aberrations cause loss of contrast in polarizing optical systems for LCOS displays. In an off‐axis system the separation of the polarizer and analyzer allows polarization aberrations to be conveniently corrected by using retardation films. In this paper we will describe how a retarder can be used to increase the limiting contrast of an off‐axis system. Limiting contrasts of greater than 3000:1 have been achieved at an f# number of 2.65. Using this technique in combination with 45 degree reflective twisted nematic microdisplay we have demonstrated system contrasts of greater than 500:1.

Authors: Daly Scott 
Published: January 2005

AbstractRecently, there is a renewed interest in improving the perceived horizontal resolution of triad‐pixel displays, such as LCDs. These techniques consider the spatial displacements of the individual red, green, and blue subpixels of the single displayed color pixel. Valid luminance information is essentially carried on a chromatic aliasing signal. Using spatiochromatic visual models, we present an analysis of the visibility of the false chromatic signal, as well as the additional luminance bandwidth.

Authors: Ha Kuendong , Park Wooill , Nozomu Arimoto 
Published: January 2005

AbstractA decent technology to solve the microphony phenomenon in the tension type jumbo CRTs of iron shadow mask has been developed. Starting from the relation between mask tension and its vibration amplitude and the relation between necessary beam‐landing margin and guard band, the minimum amplitude required to prevent an observer from recognizing beam‐mislanding is calculated. Various types of tension distribution and their corresponding mask amplitude response were analyzed and tested. So‐called the ‘Flat‐U’ type tension was resulted to be the tension distribution for minimum amplitude and doming suppression in association with an appropriate mask pattern design, we could successfully meet the set‐maker's microphony requirement.

10.3: Electro‐Optical Devices from Banana‐Shaped Liquid Crystals
Authors: Jákli Antal , Chien L‐C. , Krüerke Daniel , Sawade Hans , Heppke Gerd 
Published: January 2005

AbstractWe present the first displays using antiferroelectric smectic phases of banana‐shaped liquid crystal molecules. In appearance these displays are similar to Polymer Dispersed Liquid Crystals (PDLC) but the physical mechanisms responsible for the electrically controlled light scattering are different. In the present case the scattering is due to defect walls separating domains with different tilt directions. In addition there can be two distinct ground—states (“racemic” and “chiral”) that work in opposite ways. The racemic state is scattering in the OFF state and is optically clear under electric fields. The chiral state is transparent at zero fields and is scattering in the field ON state. These two structures may be reversibly interchanged implying their use in devices that consume energy only during switching from one stable state to other.

Published: January 2005

AbstractIn this paper, digital driving method of SCTN mode for LCOS panel is studied for 256 gray scale realization of WUXGA panel. It is found that the slow response time of nematic LC causes the discontinuity and non‐linearity of gray scales. For a natural gray scale, a short falling time of nematic LC is required. By an improved LC material and on the appropriate driving conditions, continuous 256 grays have been realized.

54.4: Thickness‐Distribution‐Controlled Two‐layer Sputter Coating for CRTs
Authors: Teng Y.‐M. , Tong H.‐S. , Hu C.‐M. 
Published: January 2005

AbstractIn order to reduce the transmission and enhance the contrast of flat panel CDT. CHUNGHWA PICTURE TUBES LTD. has developed a new two‐layer coating with adjustable transmission, low resistivity and reflectance. We use the titanium and silicon target to deposit Ti and SiO2 layer individually. By controlling the thickness of Ti layer, we can get the transmission as we need. In the same time, we can control the gas flow of each position and the scanned velocity of target to overcome the difference in transmission caused by the difference in glass thickness from center to the edge. Basically, this optimum condition can be reached by properly controlling the thickness of each layer.

AbstractThe vacuum ultra‐violet (VUV) ray emission characteristics for Plasma Display Panels (PDP) were studied using various 3‐component (He‐Ne‐Xe) gas compositions and 2‐component (He‐Xe, and Ne‐Xe) systems.In the 3‐component (Xe‐25%Ne‐He bal.) systems, an increase in the pressure and Xe content contributed to an increase in the 147nm atomic emission, whereas above a certain point this decreased. In contrast, in the 2‐component 4%Xe‐Ne bal. System, the 147 nm atomic emission was saturated with an increase in pressure. Integrated intensities of 147nm, 172nm and the total were largely changed with different measuring conditions (Vfixed and Vsus), with Xe content variation. With the increase of Xe content, when measured at Vsus, atomic emission shows maximum value at 8 % while dimer emission linearly increased. On the other hand, atomic emission shows maximum value at 4 % in Vfixed condition. Different 3‐component gas compositions with the same Xe partial pressure showed nearly the same optical properties at a fixed applied voltage. In the case of Ne, the 147nm peak increased and the 172nm peak decreased with an increasing Ne content.
