33.2: Development of 2‐in. Plastic‐Film STN‐LCD with Uniform Cell Gap
Authors: Park S. K. , Han J. I. , Kim W. K. , Kwak M. K. 
Published: January 2005

AbstractSTN LCDs on plastic film substrates for mobile communication devices have been researched and developed at KETI in KOREA. The plastic film substrate is so weak to heat and pressure that its fabrication process is limited to 110°C. The ITO electrode layer was deposited on the bare plastic film substrate by rf‐magnetron sputtering. And in order to maintain uniform cell gap and press on the plastic film substrate without deformation of substrate surface, we utilized newly invented jig and fabrication process. Electro‐optical characteristics are better than or equivalent to those of typical glass LCDs though it is thinner, lighter‐weight, and more robust than glass LCD.

Published: January 2005

AbstractA reflective TFT‐LCD with an internal diffusive micro slant reflector (DMSR) is developed to improve the previous MSR structure. The DMSR structure is optimized to obtain a desired light scattering disbribution cone while still preserving the asymmetry characteristics. A 6.4″ VGA full‐color reflective TFT‐LCD with a DMSR is realized. In this paper, we will discuss the optical perperties of the panel. The measurement results show that the reflectance is 42% compared with a Lambertian white standard and the contrast ratio is larger than 20:1.
P‐5: A New Touch‐on‐Tube CRT Touch Technology
Authors: Armstrong Donald B. 
Published: January 2005

AbstractIt has long been a dream to create an “ideal” touch monitor—a touchmonitor without a touchscreen. Such a touchmonitor could be assembled easily using existing assembly‐line techniques for monitor manufacturing. As an added benefit, the touchmonitor offers the features of a modern CRT: a durable, vandal‐resistant touch surface with an unobstructed view. Yet, with the computer display world moving from curved to flat, the question arises: Why would we want to expend effort on a new CRT technology? We believe that where there is space for a CRT it is still — and will continue to be — the most cost‐effective display available. We also believe that for the foreseeable future there will continue to be a significant demand for large CDT displays (CRTs made for monitors) for kiosks, gaming, process control, and any application that uses video. Elo's new iTouch “touch‐on‐tube” technology uses surface acoustic waves, which have been the basis for Elo's IntelliTouch overlay touchscreens for more than 10 years.

Published: January 2005

AbstractWe have developed a new TACless Wide‐View film, a successor of the current Wide‐View film, which makes the polarizer thinner and allows higher light transmittance, by eliminating one of the TAC films and directly attaching the optical compensation layers to the PVA layer of the polarizer. The new TACless Wide‐View film gives the same optical effect on the TN mode TFT‐LCD as the predecessor.

P‐14: Mechanical Drop Simulation Using FEM to Improve Shockproof Characteristic in Cathode‐Ray Tube
Authors: Park Sang‐Hu , Kim Sung‐Dae , Lee Jae‐Kee , Lee Sang‐Bong 
Published: January 2005

AbstractIn this study, the structural design concepts of main parameters of a Cathode‐Ray Tube(CRT) such as frame, spring, shadow mask were proposed to guarantee a failure‐proof CRT under mechanical shock. With the help of computer simulation, some pieces of information on the structural design were obtained as the followings; the frame and the shadow mask of CRT needed designing to increase strength, so double‐beads shape at the corner of frame was newly designed for it. And the spring, which interconnected frame with panel glass, was required to deform elastically for the purpose of absorbing the shock energy in the direction of drop. A new type of spring, it is named as ‘Twist Spring’, was designed to get the flexibility in the direction.By using them, the deformation energy, which were occurred by mechanical shock, of a shadow mask could be reduced within some degree. To accomplish those simulations, commercial codes, Pam‐Crash and I‐DEAS were used and a CRT was estimated as an example to prove the usefulness of this study.

Published: January 2005

AbstractIn order to form high‐resolusion pixels for a small organic elctroluminescent (EL) device having a three‐color independent emission system using a low molecular evaporation method, a metal mask sliding control system with a pulse control motor was made for the initial trials. This system has a substrate holding table which has the functions of rotation angle adjustment, adjustment of the XY direction movements, adjustment of the Z direction movements and an XY stage for a metal mask sliding which is based on the leaf spring structure. The patterning of the RGB thin films was done by precisely controlling the position of the XY stage for a metal mask sliding using a DC servomotor. An organic EL device, which has the sub‐pixel pitch of 33 μm × 100 μm, aperture ratio of 70% and 254 ppi (pixel/inch), has been manufactured using this system.

Organic electroluminescent devices of this type are easily produced and can be more efficient and stable as compared with usual structures.
7.2: Invited Paper: Fourth‐Generation TFT‐LCD Production Line
Authors: Chang Wonkie 
Published: January 2005

AbstractWith the explosive growth of Note‐PC and Desktop‐PC monitor market, TFT LCD market was confronted with the entire supply shortage in 1999. Forecasting a more boooming stage for the next several years, many TFT LCD panel manufacturers continue to expand the capacity of their existing plants and also make an additional investment in building new plants. The new investment is concentrated on the 4th generation TFT LCD line in order to improve investment efficiency. The setup of a Samsung's 3.5th generation line progressed satisfactorily with a glass size of 600×720mm2. We have continuously reviewed several issues regarding the glass size for our next 4th generaton line, which leads to adopt 730×920mm2. Due to the continuous enlargement of a substate size and following difficulty in transferring cassettes, the next line is expected to be the last line that employs “cassette transfer”. The layout of the next line will shift from conventional “concentration‐type” to “separation‐type” configuraton for the purpose of reducing transfer distance as well as transfer time. The details will be discussed in this paper.

AbstractOxidation and chemical modification of molybdenum micro tip surface have been investigated to understand the performance degradation mechanism of field emitter arrays(FEAs). Molybdenum FEAs could be easily oxidized due to their interaction with oxygen‐containing species including O2, CO2 and H2O during cathode fabrication or thermal sealing processes of field emission displays(FEDs). During device operation, outgassing from phosphors due to electron‐stimulated desorption and from other components inside a panel such as cathode, spacers, and sealant can lead to the chemical modification of the emitter surface. The oxidation and chemical modification of the emitter surface degrade the emission characteristics, resulting in the instability of an emission current, an increase of an electron extraction voltage for a given current, and lifetime reduction of the device. After the vacuum sealing and operation of the FED device, a micro tip is observed, and compared with an as‐grown one by using scanning electron microscopy(SEM) and transmission electron microscopy(TEM). Chemical composition analyses of the degraded emitter surface by nano‐probed Auger electron spectroscopy(AES) suggest that molybdenum micro tip is contaminated with S, In, C, and O after the device operation, where S and In seem to originate from the dissociation of phosphors by electron bombardment.

Published: January 2005

AbstractLi‐doped Gd2O3:Eu3+ phosphor was developed by the conventional solid state and sol‐gel methods. The effect of lithium concentration on the emission behavior of Gd2−x−yLixEuyO3−δ was investigated by photoluminescence and cathodoluminescence measurements. At 500 V, a cathodoluminescent efficiency of ∼180 % compared to that of commercial red‐phosphor Y2O3:Eu3+, was observed with the nominal composition of (Gd1.84Li0.08Eu0.08)O3−δ. Such a brightness is the highest among the previously reported red‐emission in the electron voltage range of 0.5 − 1 kV. This material would be a potential candidate for application in field emission display.

P‐47: High‐Luminous‐Efficiency Barrier‐Rib Structure in Color AC PDPs
Authors: Park Hun‐Gun , Park Young‐Chan , Ha Seok‐Cheon , Ryu Jae‐Hwa 
Published: January 2005

AbstractWe suggest new types of barrier rib structure of color PDP—fish bone (FB type), semi box (SB type), embossing (EB type)—to achieve high luminous efficiency. The luminous efficiency has been increased, 15%∼18%, by adapting advanced barrier rib structure without any additional production process and mask.These structures provide wider phosphor area than stripe type structure does and higher exhausting speed compared with that of box type structure. The operating voltage of FB, SB, EB is almost the same with that of conventional barrier rib type.
P‐49: Investigation on Parallel Operating Characteristics of a Closed Microhollow Cathode Discharge for Direct Current Plasma Display Panels
Authors: Park Hae , Noh Joo Hyon , Baik Hong Koo , Ryu Byung Gil 
Published: January 2005

AbstractOpen microhollow cathode discharge shows a flat (dV/dI=0) or negative behavior in current‐voltage characteristics for the entire pressure (70 to 760 Torr). On the contrary, the closed microhollow cathode discharge of 200 μm hole diameter leads to a positive differential resistance, in the range of pressure (70 to 760 Torr), without the individual ballast resistance and the distributed resistor. Also for the closed microhollow cathode discharges, the microdischarge in 200 μm hole diameter results in parallel operation characteristics at pressures higher than in 500 μm opening because of the large resistance of discharge itself as well as the small power requirement for producing the plasma in a hole. Therefore, parallel operating characteristics of microhollow cathode discharge allows us to fabricate the DC plasma display panel with high pressure and low current density.
P‐52: Birefringent Colour Reflective Liquid Crystal Displays Using Broadband Cholesteric Reflectors
Authors: van Asselt Rob , van Rooij Rob A. W. , Broer Dirk J. 
Published: January 2005

AbstractThe application of broadband cholesteric reflectors in birefringent colour reflective LCDs is described. As compared to metallic reflectors, contrast and colour saturation are better, while the brightness is comparable. Moreover, when a cholesteric reflector is used the displays can be operated in the transmissive mode, in which case complementary colours are obtained. In this way transflective displays are obtained without sacrificing brightness of the reflective or the transmissive state.
P‐55: Contrast and Brightness Enhancement of RTN‐LCDs Using Antireflective Layers
Authors: Yakovlev Dmitry , Chigrinov Vladimir , Kwok Hoi Sing 
Published: January 2005

AbstractNew constructions of RTN‐LCDs with antireflective (AR) coatings were proposed. Both one polarizer and Polarizer Beam Splitter (PBS) variants were considered. The AR coatings can be made both in the outer surface of the one‐polarizer RTN‐LCD and on the upper substrate between the glass plate and aligning layer. The damping of the LCD reflection in the “dark” state of one‐polarizer RLCD by introducing AR layers considerably improves the contrast ratio and only slightly affects the brightness of RLCD. The application of AR‐layers in PBS‐RLCD results in an improved brightness.

AbstractWe demonstrate a Holographic‐Polymer Dispersed Liquid Crystal (H‐PDLC) with an enhanced viewing‐angle, formed by writing a diffuse hologram structure directly into our H‐PDLC material. We model the diffuse H‐PDLC reflectance by summing over the contributions of discrete grating domains of differing orientations. We use a normal distribution function to weight each orientation to describe the grating densities. SEM studies were performed to determine the morphologies and orientations of multiple gratings within the sample.

P‐65: Advanced Bistability and Novel Fabrication Process for Flexible Devices of Dual Frequency Driven PDLC Displays
Authors: Ohyama J. , Kitayama H. , Ueno R. , Maruyama T. , Takeda T. , Horikiri T. , Matsuda H. , Eguchi K. 
Published: January 2005

AbstractWe have previously reported that dual frequency driven PDLC exhibits electrically reversible switching in a time for practical applications without sticking. The device retains the memory state even after removal of the driving voltage. This bistable memory switching is remarkably enhanced by a high concentration of bi‐functional prepolymers, which leads to a smaller and uniform morphology of polymer‐balls. As a result, the memory state shows a higher contrast. For a flexible type of the display, a thick resist, which is originally issued in micromechanics technology, is well applicable as the gap spacer on a plastic substrate. This simplifies the fabrication process.
