P‐114: Novel Method for Designing TFT‐LCDs with High Aperture Ratio
Authors: Jung Sung‐Min , Kim Ju‐Han , Park Woo‐Sang 
Published: January 2005

AbstractIn this study, we have developed a new method to eliminate the disclination line in the vicinity of the pixel electrode, by removing the horizontal components of the lateral field between the pixel and gate bus line electrode for the conventional thin‐film transistor liquid crystal displays (TFT‐LCDs). The horizontal components of the lateral electric fields was removed by forming the dielectric bump with high dielectric constant between the pixel and the gate bus line electrode on the TFT substrate. By performing the 3‐dimensional simulation of the molecular director profiles of liquid crystals for the given complex structure, we were able to obtain about 10% large aperture ratio than that of the conventional TFT‐LCDs.

AbstractThe computer‐modeling program that simulates 3‐dimensional structures of nematic and cholesteric liquid crystals in arbitrary complex geometries, has been developed. The program takes into account anisotropic elasticity K11≠K22≠K33, pretilt angles on the boundaries, anisotropic surface polar and azimuthal anchoring, divergence elastic term K24, and inhomogeneity of the electric field.
P‐116: Thin Crystal Films (TCF) for LCD Contrast Enhancement
Authors: Lazarev Pavel , Paukshto Michael , Fiske Tom , Silverstein Louis D. 
Published: January 2005

AbstractThe paper describes applications of Optiva thin‐crystal film (TCF) coatings to enhance the contrast and viewing angle performance of many types of LCDs. These new nano‐film polarizers are based on supramolecular lyotropic liquid crystalline materials that can be deposited (printed) on virtually any substrate. The coating dries, crystallizes and exhibits the property of an E‐type polarizer, because it transmits the extraordinary wave of light. The additional thin (∼320nm) TCF coating on the front O‐polarizer of TN LCD shows the following performance changes with respect to the baseline configuration without TCF: considerable increase in contrast ratio out to about 30° and a small drop in luminance that becomes more substantial at large angles.
P‐117: Ordering in Highly Anisotropic Liquid Crystal Nano‐Droplets: Scattering Polarizer Applications
Authors: Eakin James N. , Amimori Ichiro , Crawford Gregory P. 
Published: January 2005

AbstractBy stretching (tensile strain) a polymer dispersed liquid crystal (PDLC) film, the liquid crystal (LC) droplets become elliptical and a polarization separation optical element is created. These films have potential as scattering polarizers in liquid crystal displays (LCDs). We report a comprehensive study on the liquid crystal alignment in stretched 5CB/PVA polymer dispersed liquid crystal by means of solid‐state nuclear magnetic resonance (NMR) techniques. We are able to elucidate the nature of the liquid crystal polymer interaction by measuring the degree of orientational order at the droplet wall as a function of strain.

P‐119: New Multi‐Domain Vertical Alignment LCD with High Contrast Ratio and Symmetrical Wide Viewing Angle Performance and Simplest Fabrication Design and Process
Authors: Ong Hiap L. , Cheong Ngwe , Lo Jason , Metras Marty , Woodard Ollie 
Published: January 2005

AbstractWe invented and successfully fabricated a new multi‐domain vertical alignment (MVA) LCD with high contrast ratio and wide symmetrical viewing‐angle performance. The LCD has a simple fabrication process without rubbing, with no surface protrusion, and no ITO slit geometry. The new MVA LCD makes use of the intrinsic fringe field in each pixel to control the LC alignment, and manifesting 2 domains under column inversion and row inversion, and 4 domains under pixel inversion operation. The viewing angle can be enlarged by the use of optical compensation films, and transmission can be enlarged by improved LC material, drive voltage, pixel design and circular polarizers.
P‐121: Optical Anisotropic Compensator by Polymer Stabilization Technique
Authors: Doi Toru , Chien Liang‐Chy 
Published: January 2005

AbstractPolymer stabilization technique was applied for making optical anisotropic compensators for the purpose of controlling the wave length dispersion characteristic. Quarter wave compensators with hybrid aligned structure were prepared by this technique using liquid crystals (LCs) with different optical birefringence (Δn). The wavelength dispersion of the resulting compensators depended on the Δn of the LC used. The compensator using LC with the smallest Δn was found to give almost same retardation value over the wide range of visible light. Hybrid compensators were combined with hybrid aligned liquid crystal cells for reflective‐ LCD application. The hybrid compensator with very low wavelength dispersion gave the reversed dispersion characteristics very close to the ideal one at black state.

Published: January 2005

AbstractWe have developed a novel ultra‐thin hybrid aligned nematic compensator (NH film) for wide‐viewing‐angle transflective TFT‐LCDs. The influence of the substrate film on the viewing angle performance is discussed. By eliminating the substrate of the NH film, the total thickness of the compensator can be reduced dramatically. We also confirmed the durability of this ultra‐thin compensator.

Published: January 2005

AbstractBy using a single high power Light Emitting Diode (LED) and a small size transmissive LCD very compact projectors, which can be run from batteries, can be built. Such a projector can be used in combination with or integrated into a PDA or digital camera to project images or presentations in a small size format, and would be used whenever a laptop would be unavailable or clumsy. For these types of applications the required flux can be low. We have build a very small (prototype) projector using a single, high power LED, a small LCD, and a small projection lens. The light output of such a configuration is in the range of 5 to 10 lm, which is sufficient for the projected image sizes as indicated above. In this paper we well describe the system and its performance and size, and elaborate on alternative configurations and performance.

Authors: Travis Adrian , Zhong Joe 
Published: January 2005

AbstractFlat projection displays promise the convenience of a flat panel with the low manufacturing costs of projection. The displays can be made by pointing a video projector into the thick end of a wedge‐shaped piece of glass or acrylic, but it is important that the projected image be undistorted. It is shown here that paraxial wedge projection is linear, so that the projection lens can be designed using conventional lens shapes and combinations.

Published: January 2005

AbstractThe Hopping Field Emission Display (HopFED) is a new architecture for field emission displays. In this architecture electrons from each sub‐pixel are transported in a hopping mode via secondary electron emission over the wall of a funnel placed above the sub‐pixel emitters. This leads to the following advantages: Improved sub‐pixel electron spot, improved contrast and color purity, reduced damage to field emitters by ion‐bombardment and a low capacitance addressing option.

Published: January 2005

AbstractA transparent thin film desiccant capable of improving the storage reliability of OLED was developed, which was named OleDry. OleDry is an excellent desiccant mainly composed of aluminum complex, which well dissolves in hydrocarbon solvent. Taking advantage of the dissolubility of aluminum complex, transparent thin film can be formed by coating OleDry on the inner surface of the cover glass and drying it. Not only to the standard OLEDs, a thin transparent OLED, a top‐emission OLED and even a flexible OLED using resin substrate are viable with high storage reliability by the use of OleDry.

AbstractThis paper focuses on the secondary electron emission coefficient (γ) and the degradation dynamics of the MgO protecting layer. It is demonstrated that the γ could be improved by 50 % at the maximum using an ion implantation technique. We discuss that the γ improvement is not based on the same principle as reported in the thermally equilibrium compound. As for the degradation dynamic, we point out that the desorption of MgO clusters from the MgO surface is enhanced in the surface normal direction by applying a bias voltage to the substrate. From a computer simulation, it is confirmed for the first time that the desorption of MgO constituent, in other words, the surface degradation, is certainly occurring under the electric field condition.

Published: January 2005

AbstractIn this paper, cathodes and gate electrodes structure of a CNT tube and its fundamental characteristics such as brightness, drive voltage vs emission current, adjacent leakage of light and emission life are described. The brightness of 3000 cd/m2 was obtained with a 10 kV anode voltage and a 0.5 mA anode current. The CNT cathode was made by printing to achieve low costs, and its thickness was approximately 10 μm. The gaps between the bare cathodes glass and the gate electrodes were about 50 μm, therefore, the gaps between the CNT cathodes and the gate electrodes were 40 μm. An emission current up to 2.5 mA was extracted by applying pulse voltage of 200‐300V to the gate electrode and about 20% reached the anode to excite the phosphor. The variation in electron emissions was measured over 6000 hours, and it was found that a sharp decrease of the emission current occurred at an early stage of the test and then it decreased gradually. It is very important for the successful manufacturing of the CNT tube to avoid a short circuit between the cathodes and the gate electrodes. We added some adhesive additives to the CNT paste and achieved no short circuits between them.

AbstractWe have revealed that the carbon nanotube(CNT) nanoscale material should be applicable as the field emitter for display devices. In IDRC'01, we developed an improved structure in order to realize an uniform luminance all over the large display area. The results revealed that the new structure performed the luminous uniformity with high‐luminance. And the structure was applied for a larger size panel. Experimentally, we performed up to a 40‐inch size CNT‐FED panel in SID'02. In this study, we investigated the various factors of CNT‐FED in order to improve luminous uniformity, low driving voltage and high luminance for actual displays. The improved CNT‐FED panel will display characters and graphics by high luminance color pixels.
