Authors: Ou C. R. , Lee W. T. , Yaung C. F. , Lin H. S. , Wu Y. L. , Yoo J. C. 
Published: January 2005

AbstractITRI/OES has developed a system for the measurements of LCoS systems. This equipment is designed to be an experimental toolkit for the study of different optical elements under different configurations and environments. Using this apparatus we performs several thermal experiments on a PBS. The experimental results indicate that the thermal effects on the PBS are conspicuous. An optimal working temperature is required for the PBS to get a good image quality. Experiments on stress birefringence effects of the PBS are also made.

Published: January 2005

AbstractWe developed self‐organized carbon nano‐tips using a high density plasma CVD. A C2H2/H2 mixture was used as source gas for the deposition.

P‐94: A Novel Method to Eliminate Fringe Field Effects for Small Pixels on LCoS
Authors: Chuang Li‐Sen , Chang Yu‐Ching , Chou Wei‐Yang , Hsu Ching‐Hsiang 
Published: January 2005

AbstractA new LC mode which implements finger‐on‐plane (FOP) type common electrodes in a reflective light valve is proposed. The appropriate electrode geometry or shape design can overcome the problem of poor contrast ratio and low light efficiency in conventional LCoS. The simulation results indicate that the reflectance can reach above 80% even for the worst case in frame and column inversion driving schemes. We will also demonstrate that our device exhibit low dispersion in single cell gap configuration.
P‐95: Fresnel Lenses in Rear Projection Displays
Authors: Davis Arthur , Bush Robert C. , Harvey John C. , Foley Michael F. 
Published: January 2005

AbstractA plastic Fresnel lens positioned just before the diffusion screen in a projection system can provide significantly superior corner illumination, enhancing overall display luminance uniformity. Fresnel lenses are also used within the light engine to collimate light through the LCD panel and focus light through the projection lens. Disadvantages include the added cost of the lenses, ghosting, printout of the Fresnel rings and moiré patterns. Birefringence is important to control in polarization‐sensitive applications.Without reduction of ghosting artifacts, Fresnel lenses will have limited application in text‐based RP systems. Ghosting is described in some detail including how it is caused, quantified and reduced. Efforts to reduce cost and birefringence will also be discussed.
P‐98: Acousto‐Optic Separator for Stereoscopic Laser Videoprojection
Authors: Kastelik J. C. , Sakkour A. , Pommeray M. , Gazalet M. 
Published: January 2005

AbstractIn this paper, we present an original acousto‐optic device which allows to separate an arbitrary polarised incident light beam into two orthogonally polarised diffracted beams. This device operates with a single frequency ultrasonic wave and the two diffracted orders are frequency up and down shifted, respectively. A birefringent crystal of Paratellurite has been chosen for experimental validation due to its very high acousto‐optic figure of merit for the slow acoustic shear wave. This device has been conceived in order to be implemented in a optical modulation line of a stereoscopic laser videoprojector based on the simultaneous projection of the two left and right images orthogonally polarised. Special polarising glasses select the two images for each eye. The projection is based on a X‐Y scanning of a laser beam which is both intensity and polarisation modulated. The “on‐line” separator allows to dynamically control and minimize the “ghost” phenomenon of a such a stereoscopic system.

34.4: Liquid Crystal Alignment Degradation Induced by Photo‐irradiation
Authors: Barna Hayley , Lu Minhua , Samant Mahesh , Cai Chen , Rosenbluth Alan 
Published: January 2005

AbstractDegradation of liquid crystal alignment has been studied by monitoring the change in pre‐tilt angle as a function of UV dosage, as well as by surface analysis methods, such as NEXAFS and surface energy measurement. The mechanism of the alignment degradation was understood for the first time at the surface chemistry level. The degradation happened in two steps. First there is oxygen absorption, followed by liquid crystal attachment. In addition, we have shown that filtering out short wavelengths is effective in prolonging the lifetime of liquid crystal displays. This work is important for improving display lifetime and quality.
35.2: Super‐TFT‐LCD for Moving Picture Images with the Blink Backlight System
Authors: Hirakata Jun‐ichi , Shingai Akira , Tanaka Yoshinori , Ono Kikuo , Furuhashi Tsutomu 
Published: January 2005

AbstractA 15‐inch diagonal Super‐TFT‐LCD (in‐plane switching mode), with a brightness of 400 cd/m2, has been developed. The moving picture image quality is improved by alternating the light on and off periods, and synchronizing those periods with a gate selection. The brightness is realized without increasing power consumption by increasing the lamp current in the on period, while the off period contributes to lamp cooing.

Published: January 2005

AbstractCarbon‐nitrogen CN nanofibers have been formed by high isostatic pressure HIP. Emission properties of CN nanofibers were investigated for spacing, between anode and cathode, variation. Then turn‐on fields about 1.4 V/μm. The time reliability and light emission test were carried out for above 100 hours. We suggest that CN nanofibers can be possibly applied to the high brightness flat lamp because of low turn‐on field and time reliability.

AbstractA 20‐inch, largest OLED display in the world is demonstrated which is driven by “Super Amorphous Silicon” technology. It has been widely believed that the characteristics of amorphous silicon TFT is not sufficient to drive OLED display. This paper turns over the hypothesis to prove that amorphous silicon can be applied to the large active‐matrix driven displays. Novel approaches to enable amorphous silicon to drive bright and long life OLED display are shown to open a bright future to realize larger OLED televisions.

Published: January 2005

AbstractA new low‐temperature polycrystalline‐silicon LTPS process was developed. The doping mask for p‐type TFT was compared with PR mask and gate hard mask. The process and design challenge in gate hard mask was compared with the photo resist residues problem encountered in PR mask process. In the gate hard mask technology, the gates of p‐type and n‐type TFTs are etched in different steps for p‐type TFT S/D doping and n‐type TFT LDD doping. The results indicate the gate insulator loss and the CD loss due to these different etching steps can be controlled in the same magnitude, and the TFT electrical characteristics of NMOS and PMOS are good enough for pixel and driver applications.

P‐18: Damage to TFT Displays During Polariser Replacement ‐ Analysis of Damaged Displays, Failure Mechanism, and Proposed Safe Removal Method
Authors: Hampel Reinhard G. O. , Vial‐David Gérard 
Published: January 2005

AbstractOur customers stated uneven greyscales ‘clouds’ in TFT displays after polariser replacement. We counted spacer densities on displays before and after polariser removal by different methods. We found that the average spacer count falls to about 40% of its initial value after unsafe polariser removal. From microscopic observation of spacer distribution in pixels, we could conclude that the spacers get ‘trapped’ by the metal lines connecting the pixels. Unsafe removal methods exert a pressure on the LCD close to the polariser peel line. This induces a pumping action resulting in strong LC flow. The spacers moving with the LC liquid get trapped by the metal lines on the TFT substrate, and the spacers ‘disappear’ from the pixels. Condition for a safe removal method is thus that no pressure must be applied to the displays close to the peel line, close being defined as a distance of less than about 20–30 mm.
