Authors: Gille Jennifer , Lewis Alan , Hastings Scot , Chui Clarence 
Published: August 2007

AbstractAppropriate color bit depth for user acceptability of small portable displays depends on contrast ratio, gamut, gamma, pixel pitch, dither, size and uses. We determined target bit depth values for an interference‐color reflective display, testing acceptability and artifact visibility using diverse observers and images in a display‐Simulation optical system.
27.3: When is Sub‐Sampling in RGB Displays Practical?
Authors: Miller Michael E. , Arnold Andrew D. , Tutt Lee 
Published: August 2007

AbstractThe availability of more precise patterning continues to enable flat panel displays with higher resolution and addressability. As resolution increases, it becomes increasingly difficult for users to perceive individual light‐emitting elements within a pixel. This paper explores the impact of several arrangements of light‐emitting elements having fewer red and blue than green light‐emitting elements on image quality, including displays providing two‐color emission from spatially coincident areas.

Authors: Willemsen Oscar H. , de Zwart Siebe T. , Hiddink Martin G. H. , de Boer Dick K. G. , Krijn Marcel P. C. M. 
Published: August 2007

AbstractIn this paper we analyze the performance of multi‐view barrier and lenticular based 3D displays in their most important display properties, being resolution, brightness, uniformity and cross‐talk. We will show that the barrier display is superior in uniformity and that the lenticular is superior in brightness. We will show that the cross‐talk and uniformity of an ideal slanted barrier equal that of an ideal defocused lens. for a realistic barrier we will show that diffraction increases the cross‐talk but does not change the uniformity. We will also show that the spherical aberrations of the cylindrical lens limit the uniformity of the display but do not affect the cross‐talk.
28.2: Stereoscopic Near to Eye Display using a Single Microdisplay
Authors: Levola Tapani 
Published: August 2007

AbstractA binocular Near to Eye Displays (NED) offering stereoscopic images is technically very challenging to realize. Already in a biocular system, there are many issues related to health and wellbeing although both eyes get an identical image. The virtual reality display (VRD), based on planar waveguide, offers an opportunity to realize a stereoscopic, ergonomically superior NED, if it is based on a single optical system offering images for both eyes. In this paper it is discussed how frame sequential stereoscopic images can be shown using a planar waveguide based NED. This system has only a single microdisplay and single image formation optics. The illumination of the LCD in this stereoscopic application differs from the biocular one. It is essential that the diffractive planar waveguide has very asymmetric grating profiles. An example of a design of a planar waveguide based optical engine is shown.

Published: August 2007

AbstractWe have developed the stereo‐corresponding algorithm using edge information. The conventional stereo‐corresponding algorithm, SAD (Sum of Absolute Difference), has a good quality in case of texture region, but it has a false matching in the non‐texture region. In order to reduce the false matching in the non‐texture region, the new cost function, which is defined as SED (Sum of Edge Difference) based on the global optimization, is added to the cost function of SAD. We evaluate our algorithm and benchmark Middlebury database. The experimental results show that our proposed algorithm successfully produces piecewise smooth disparity maps while reducing the false matching in the non‐texture region. Moreover, our algorithm is faster in getting the best quality than SAD.

Published: August 2007

AbstractWe developed a 5.5 inch, VGA (640×480×RGB), stereoscopic 3D display using a precisely patterned wire grid polarizer (WGP) with rows of alternating polarization angle. Such a wire grid polarizer is invisible without the polarizer and thus a 2D/3D convertible display can be formed. The proposed structure is free of any limitations on both viewing angle and viewing distance inherent in the conventional stereoscopic displays, whereby enabling several persons to view stereoscopic image simultaneously. Because the proposed structure does not use conventional polarization film of TFT‐LCD panel, it can be manufactured with low‐cost.

Authors: Lin Chi‐Huang , Chen Ren‐Lu , Huang Kuang‐Yong 
Published: August 2007

AbstractA new multi‐domain vertical‐alignment liquid crystal display (MVA‐LCD) is developed to achieve high transmittance, high contrast ratio and wide viewing angle. According to this design, the MVA‐LCD has a high transmittance by using conventional polarizer rather than circular polarizer. Accordingly, high contrast ratio, wide viewing angle and high transmittance can be achieved for MVA‐LCD simultaneously. Potential application for mobile display is emphasized.

AbstractA novel low‐cost and high contrast‐ratio IPS (in‐plane switching) LC mode, named Advanced Super Non‐Organic Overcoat (AS‐NOOC), has been successfully developed. Compared to the published AS‐IPS mode, the AS‐NOOC mode has the advantages of simpler process for lower manufacture cost by the elimination of a lithographic process step to form thick organic overcoat on the array substrate, and a higher contrast ratio by using narrow strips of black matrix serving as common electrodes on the color‐filter substrate to reduce the light leakage caused by fringe fields of data‐bus lines in the dark state of the display.

Published: August 2007

AbstractAggregating PAHs of the perylene class are useful as LEL additives. They greatly improve the device operating half‐life up to 1,000,000 h at the initial luminance of 1540 cd/m2 (20 mA/cm2). There appear to be at least three factors in the lifetime increase: takeover of the LEL functions by the PAHs, aggregation, and an expansion of the recombination and/or emission zone.

Published: August 2007

AbstractCurrently, three issues are identified that decide upon the commercial success of organic light emitting diodes (OLEDs), both in display and lighting applications: power efficiency, lifetime, and price competitiveness. PIN OLEDs are widely seen as the preferred way to maximum power efficiency. Here, we report that this concept also delivers the world longest lifetimes. for a highly efficient deep red PIN OLED, a half lifetime of 25,000 hours for a starting brightness of 10,000 cd/m2and a minimal voltage increase over lifetime is reported. This value corresponds to more than 1 Million hours at 500 cd/m2assuming a rather low exponent of n = 1.3 only. Since there is no initial luminance drop, these PIN OLEDs also exhibit a very high 80% lifetime (250,000 hours at 500 cd/m2). In the following, new record lifetime values for blue and green will be reported. Additionally, further topics that have impact on the production yield and cost such as newly developed materials and top emitting structures will be discussed.

Published: August 2007

AbstractThe Communications Research Centre (CRC) Canada has been conducting research on 3D‐TV and related stereoscopic technologies since 1995. Three areas of CRC's research on human stereoscopic vision and its application to 3D‐TV are highlighted. Firstly, we will present our work on the use of inter‐ocular masking to reduce bandwidth requirements, without sacrificing high image quality. Secondly, we will present experimental results that show the effect of stereoscopic objects in motion on visual comfort. Thirdly, we will present studies to illustrate how the tendency of the human visuo‐cognitive system to correct or fill in missing visual information can be used to generate effective stereoscopic images from sparse depth maps.

34‐1: Electrode Structure for Fringe‐Field Switching Mode with Reduced Color Shift
Authors: Lee Gak Seok , Kim Jae Chang , Yoon Tae‐Hoon 
Published: August 2007

AbstractWe propose a new electrode structure for the fringe‐field switching mode, which not only has a smaller color shift but also transmits more light than the chevron‐type structure. While the chevron‐type electrode structure mainly uses the different directions of the electric field, the proposed structure makes use of position‐dependent strengths as well as different directions of the electric field. Position‐dependent electric field strengths bring about rotation of LCs different from position to position in a pixel, which further reduce the color shift by using the multi‐domain effect.

Authors: Kang Myung‐Koo , Uh Keehan , Kim HyungGuel 
Published: August 2007

AbstractThe new technologies in mobile display developed in SEC are briefly reviewed. for a differentiation, SEC's LTPS line is based on SLS (Sequential Lateral Solidification) technology. In this paper, the characteristics of SEC's SLS in recent and future mobile displays were discussed. SLS has a strong point in productivity and higher performance but has a weak point in uniformity and property anisotropy. Uniformity could be improved by tilt engineering and property anisotropy by multichannel structure. By overcoming weaknesses, SLS could be basic crystallization technology for SEC's LTPS mass production line.A‐Si TFT technology is also important in low resolution display or mid to large size mobile applications due to its lower fabrication cost. SEC has developed successfully both a‐Si and LTPS technologies as a portfolio. Cost‐competitive a‐Si base TFT‐LCD could be developed using advanced technologies such as ASG (Amorphous Silicon Gate).For value‐added functions, SEC has developed ADC(Automatic Dimming Control), h‐TSP (Hybrid Touch Screen Panel) ADC can make low power consumption devices. H‐TSP has two kinds of types and SEC has developed both successfully to the mass production level.

Published: August 2007

AbstractA unique gated cathode structure for a Carbon Nanotube‐based field emission display has been designed and built. This structure optimizes the electron beam profiles so as to assure high anode electron efficiency and a good color gamut without requiring specific focusing electrodes or structure. A computer simulation written to analyze and aid with the design shows good correlation with the experimental data and also helps to predict design margins. A full color frit‐sealed display built with the approach demonstrates an excellent color gamut of the phosphor, and the model predicts avenues for increasing the color gamut further.

Published: August 2007

Abstract(Y, Gd) BO3: Eu3+ and BaMgAl10O17: Eu2+ phosphors were synthesized and coated by using a colloidal silica to improve photoluminescence (PL) spectroscopy and luminescences. We can show that the surface coating of the phosphors with SiO2 nano particles leads to an enhancement in luminance intensity of PDP devices. This may because the increase of the excitation light which is transmitted into the phosphors. The experimental results suggest that the surface coating of the phosphors with SiO2 nano particles is a way to improve PL and luminescences of plasma display panel.
