Published: January 2005

AbstractDisplay technology is a rapidly growing market. Manufacturers of flat panel displays are urged to reduce their manufacturing costs to be competitive on the market.The growing application of plastic sheets and plastic films in display manufacturing requires a hard coating for enhancing the abrasion resistance or for serving as a basic layer for optical coatings. Oxide layers excel in high hardness and abrasion resistance. Utilizing the unique new Hollow cathode Activated Deposition (HAD) technology developed at FEP, allows tQ obtain oxide layers of optical clarity at very high deposition rates (100…500 nm/s) on large substrates. These high rates give the opportunity of economical deposition of thick oxide layers for displays. This new technological breakthrough will allow to fabricate larger flat panels with less weight and to increase the design capabilities of display manufacturers. As an example, this technology allows to provide polycarbonate with an abrasion resistance equal to that of normal float glass. This paper will address the new Hollow cathode Activated Deposition (HAD) technology to display manufacturers.

Authors: Yu Sai , Penn Cecil , Jachimowicz Karen , Silverstein Louis D. 
Published: January 2005

AbstractA psychophysical experiment was conducted to investigate the effect of field emission display (FED) fill factor on display image quality. A two‐alternative, forced‐choice psychophysical task was employed to obtain judgments of image coarseness and overall image quality as a function of three fill factors, 30 percent, 40 percent and 69 percent of VGA resolution FEDs. The results revealed that FED imaging performance is not improved by increasing the fill factor of 325 micron pixel pitch FEDs, provided that space‐average luminance is maintained constant.

AbstractA ridge and fringe field multi‐domain homeotropic (RFFMH) liquid crystal display was demonstrated. The operating principle of this new display mode is the combination effect of a fringe field and ridge structure to control the tilt direction of the liquid crystal molecules when a voltage is applied. No rubbing treatment is required and, with proper compensation films, the display has very wide viewing angles.

AbstractThe author proposes an illumination optics system for LC‐projection displays to improve optical efficiency. It uses a pair of special lenses whose surface profiles are determined so that the circular cross section of the incident light beam is transformed into a rectangular one. Nonlinear least squares fitting and ray‐tracing is combined to determine the surface profile parameters. The design and the results of the performance simulation are presented. The method is expected to provide high‐efficiency, well‐collimated illumination.

AbstractThe performance of ferroelectric liquid crysta displays are particularly sensitive to achieving the correct alignment conditions. Topographical studies of the surface layers of a colour FLCD have been made using tapping mode atomic force (AFM). The results are compared with detailed studies of test cells at different stages of device fabrication. An understanding of the relationship between the nanoscopic structure of the surfaces and the bulk alignment of the liquid crystal is developed. This enables device properties such as speed, contrast and viewing angle to be improved uniformly over the panel.

AbstractThis paper discusses the methods that the Military Aircraft & Aerostructures Division of British Aerospace Defence have developed over the last two decades to specify and assess cockpit displays. It is primarily concerned with single seat fast jet aircraft though it could also apply to any display applications where high levels of ambient illumination are present. The specification method is based around a modelling technique referred to as the Perceived Just Noticeable Difference (PJND) method. The assessment method is based around a purpose built ‘lighting’ chamber.

Published: January 2005

AbstractA new concept LCD backlighting system using the highly scattering optical transmission (HSOT) polymer has twice the brightness of the conventional backlight and uniform illumination. Light scattering phenomenon of a spherical particle inside the HSOT polymer is calculated exactly by the Mie scattering theory. It was confirmed theoretically that the color illuminated from the HSOT backlight could be controlled by the specified scatterer. In this paper, we reported the latest HSOT backlighting system having high efficiency and high color uniformity by optimizing the light scattering phenomena inside the light pipe. Also, these techniques developing efficiency and color lead to enlarging the size of the backlighting system.

AMLCD on plastic substrates
Authors: Sandoe J. N. 
Published: January 2005

Abstract:A review of the advantages of plastic substrates for AMLCD shows that the initial market is likely to be in the ‘hand held’ portable computing area. There, the combination of ruggedness, low weight and high performance will become essential.Work on top gate TFT devices made using the industry standard PECVD deposition of a‐Si and SiN shows that growth at temperatures suitable for poly‐ethyl sulphone (PES) substrates can lead to excellent device characteristics. A key issues with PES is the dimensional instability during etching between lithography steps. A TFT ‘finger’ design allows for dimensional changes and provides acceptable display performance.

Authors: Chiang Chun‐Sung , Martin Sandrine , Nahm Jeong‐Yeop , Kanicki Jerzy , Ugai Yasuhiro , Yukawa Teizo , Takeuchi Shu 
Published: January 2005

AbstractHigh‐performance top‐gate hydrogenated amorphous silicon (a‐Si:H) thin‐film transistor (TFT) structures have been fabricated over a large area from plasma‐enhanced chemical vapor deposition (PECVD) materials. The electrical performances of the top‐gate a‐Si:H TFT (μFE≅0.75cm2/Vsec, VT≅3.5V, S≅0.55V/dec) are comparable to the electrical performances observed for an inverted‐staggered bottom‐gate a‐Si:H TFT. We have shown that the TFT field‐effect mobility first increases with the a‐Si:H thickness, and then decreases for thicker a‐Si:H films. This change of the electrical performances can be associated either with the variation of a‐Si:H microstructure with film thickness during the PECVD processes or a large density of TFT back interface states; it also involves the source/drain parasitic access resistances, especially for thick a‐Si:H layers.

Published: January 2005

AbstractMaterials and components for IPS (in‐plane switching) ‐TFT‐LCDS are optimized based on a basic analysis of the in‐plane switching behavior of nematic liquid crystals. We have newly developed materials and components accessible for mass producible and commercially available IPS‐TFT‐LCDS. New phenomena unlike from that found in conventional TN‐TFT‐LCD cases, such as a higher holding ratio characteristic which is specific to the IPS mode, are found. An optimization procedure for a liquid crystal mixture and a color filter is reviewed. By using new materials and components, we have supplied an IPS‐TFT‐LCD module consisting of a common driver LSI whose driving voltage is 5 volts with a response speed of 60ms (rise+fall), almost comparable to that of conventional TN‐TFT‐LCDs. Finally, our recent development state toward a faster response speed of 25ms, which is applicable to a moving picture display, is discussed.

Published: January 2005

AbstractIPS Display is one of the promising technologies for the larger Liquid Crystal Displays (LCDs) of monitors for the desk top computers and TVs with a very good feature of viewing angle dependence. The requirement of IPS displays upon liquid crystal materials is different from TN‐TFT displays.Taking this different requirement into consideration we have performed a characterization of liquid crystal materials for optimizing the mixture design. Identifying new liquid crystal materials we have succeeded in improving the viscous property of mixtures which would enable the full moving pictures of IPS displays.
27.4: Investigation into Variable Addressibility Image Sensors and Display Systems
Authors: Kubala K. , Hatch A. , Hooker R. B. , Lewis L. 
Published: January 2005

AbstractThe eye's acuity varies across its field of view, decreasing to 10% of its axial value at only 20 degrees. This creates a situation where standard displays, when used in conjunction with the eye, present more information than can be perceived. This paper describes an optical system that has been developed that radially re‐maps the pixels of a miniature display or sensor to match the varying acuity of the eye across its field of view. This system increases the field of view of an electronic viewing system without any apparent loss in image quality.
