P‐97: A Novel Transflective Display Associated with Fringe‐Field Switching
Authors: Jung T. B. , Lee S. H. , Park C. H. , Kim H. Y. , Jeong Y. H. , Lee S. K. , Lim Y. J. 
Published: January 2005

AbstractWe have designed a novel transflective nematic liquid crystal (LC) cell driven by a fringe field. A homogeneously aligned LC director rotates almost in plane by applying voltage and, thus, the LC cell becomes an excellent dynamic phase retarder. The transflective display associated with this LC cell exhibits a wideviewing‐angle in both reflective and transmissive displays.
17.3: Improvement of the Speed of Address Discharges in Ne‐Xe‐He Discharge Gases for ACPDPs
Authors: Uemura Norihiro , Yajima Yusuke , Shibata Masayuki , Kawanami Yoshimi , Namiki Fumihiro 
Published: January 2005

AbstractThe time lag of address discharges is discussed in terms of its relation with discharge gas composition. We measured the discharge time lag in ACPDPs with Ne‐Xe‐He mixed gases. As the concentration of helium increases, the address discharge time lag becomes shortened because helium atoms reduce mostly the formative time lag of the discharge. The formative time lag depends on the ion drift velocity at the initial stage of discharge formation. This ion drift velocity becomes lager with higher helium atom concentration.

Published: January 2005

AbstractThe effect of monitor bezel color (diffuse reflectance) on task performance, visual abilities, subjective comfort level, and preference in using software with graphical user interfaces was measured. Frame color had no effect on task performance or visual metrics (acuity, contrast sensitivity). Subjective ratings of discomfort were similarly higher at the end of 4 hours of work across all monitor bezel colors. The darkest bezel color was preferred by 2/3 of the participants at the end of 3 days, after using a different monitor bezel color on each day.

Published: January 2005

AbstractPhoton‐mode full‐color rewritable image has been demonstrated. Three kinds of photochromic fulgides were used as rewritable dyes. Photochromic fulgides and polystyrene were mixed and coated on a white polyethylene terephthalate film. On irradiation with three (red, green, and blue) visible light beams, wide hue extent, high white reflectance over 80 %, and high contrast ratio over 45 were attained. A full‐color image keeps their colors over an hour under the standard office brightness (700 lx) without substantial fatigues. The photochemical coloration‐decoloration cycles could be repeated over 100 times.
22.2: Application and Optimized Design of Wire‐Grid Polarizers
Authors: Yu X. J. , Kwok H. S. 
Published: January 2005

AbstractThe properties of wire‐grid polarizers (WGP) are studied and optimized. Experimentally, the efficiency and the contrast ratio of the projection system using WGP are investigated as a function of the incident angle. It is confirmed that WGP can afford large extinction ratios and large numerical apertures (NA). However, WGP suffers from the drawback of large absorption by the metal grid. We calculated the properties of the WGP as a function of its physical parameters using rigorous diffraction theory. Optimal designs are obtained based on the criteria of best optical performances (high efficiency, large NA, large extinction ratio). With these optimal physical parameters the WGP can show very good performance with efficiency >85%, large NA, and high extinction ratio >1000.

Published: January 2005

AbstractWe have developed a polymer dispersed cholesteric liquid crystal which exhibits two stable states at zero field: reflecting planar texture and non‐reflective focal conic texture. Both states have thresholds under driving voltage pulses. The material can be used to make multiplexed displays on passive matrix. Because the liquid crystal is encapsulated, the dispersion can be coated on plastic substrates to make large size displays. Furthermore, it can be used to make single layer full color displays by using a photo‐tuning method.

Authors: Asano Akihiko , Kinoshita Tomoatsu , Otani Natsuki 
Published: January 2005

AbstractAn all‐plastic, reflective color LTPS TFT LCD has been developed with a typical PDA‐size of 3.8‐inch in diagonal. This panel has 0.4mm in thickness and weighs only three grams. The TFT layer on a plastic substrate was prepared in our original transfer process, which does not leave any significant damage to the device layer. Owing to the flexibility of the substrates, the panel can be bent with an image displayed in operation. The changes in LTPS TFT characteristics with a substrate bending are also investigated for the first time, which reveals a mobility change of 16% under 0.75% compression. This technology will allow us to make a lightweight, shock‐resistant LCD panel practically, which is well suited to mobile applications.

Published: January 2005

AbstractTop gate and bottom gate microcrystalline silicon thin film transistors (TFTs) have been produced by the radio frequency glow discharge technique using three preparation methods: the standard hydrogen dilution of silane in hydrogen, the use of the layer‐by‐layer technique, and the use of SiF4‐Ar‐H2 feedstock. In all cases, stable top gate TFT with mobility values around 1 cm2/V.s have been achieved, making them suitable for basic circuit on glass applications. Moreover, the use of SiF4 gas combined with specific treatments of the a‐SiN:H dielectric in bottom gate TFTs, fully compatible with today's a‐Si:H production facilities, lead to an enhancement of the mobility which reaches stable values around 3 cm2/V.s.

AbstractIt is well known that backlights for Liquid Crystal Displays (LCDs) based on Red, Green and Blue Light Emitting Diodes (RGB LEDs) render superior color quality but do require control of white point over temperature and lifetime [3], [4], [5]. We have developed a novel backlighting system utilizing RGB LED lightsources, a color sensor and a feedback controller. The main result of using optical feedback is a color stability Δ u'v' < 0.002 (CIE1976) over temperature. Optionally, brightness can be maintained constant. The system can control any color point or brightness required.

AbstractA novel LED light source, “Luxeon Direct”, has been integrated into a highly efficient direct backlight. This concept incorporates one of the latest LEDs released by Lumileds™. This direct backlight approach integrates side emitting LEDs with a highly reflective cavity placed behind the LCD. Prior to this method it has been very difficult to use high power red, green and blue (RGB) LEDs in a direct backlight design due to the high color and brightness uniformity requirements. In this paper a method will be demonstrated that can achieve excellent backlight performance using an indirect illumination approach with high power LEDs.

49.2: Reduction of LCTV Backlight Power and Enhancement of Gray Scale Capability by Using an Adaptive Dimming Technique
Authors: Shiga T. , Mikoshiba S. 
Published: January 2005

AbstractAn adaptive dimming technique is introduced for reducing the backlight power consumption in LCTVs. With the technique, the backlight luminance is adjusted according to the input TV signal. For example, when the original input signal is small, the backlight luminance is reduced and the signal is increased so that the perceived luminance is equal to that before the signal processing. From a simulation, backlight power reduction to 1/3 can be expected for APL 25% image. The gray scale capability at low luminance levels is also enhanced.
50.2: 2‐D Modeling of the Effect of Electrode Topography and Interpixel Gap on LCoS Devices
Authors: Zhang Y. L. , Bos P. J. , Chung D. B. 
Published: January 2005

AbstractWhile there has been considerable modeling of the walls that can form in a LCOS device due to the fringing fields around the pixel electrodes, the procedures often have used simplifications. The importance of understanding these walls when very small pixels are considered has motivated us to look at some of the often‐made assumptions more carefully. In this paper we model the wall due to fringing fields taking into account the topography of the electrodes and pretilt angle, and the optical effect is modeled using the Finite Difference Time Domain (FDTD). The interpixel gap on the non‐ideal light reflection is also studied.

Published: January 2005

AbstractHigh production cost of the TFT‐LCDs is closely related to the complication of the fabrication process. To simplify the fabrication process, it is critical to reduce the number of mask‐count. In this paper, 4‐mask‐count TFT‐array process using slit (or gray‐tone) photolithography technology is introduced. Various kinds of the geometrical slit designs and the exposure conditions have been simulated and experimentally optimized. By adopting this novel process, TFT channel is defined without using additional photolithography.

The AMA‐LCF is laminated to the top surface of the reflective LCDs, and directs incident light into a reflected cone near normal to the display surface, yielding a gain about 1X to 10X of MgO standard‐white at the typical viewing region from 0° to 20°. Moreover, glare can be greatly reduced.

Published: January 2005

AbstractThe fabrication process of low temperature poly‐Si (LTPS) TFT can be simplified by p‐type technology. It is expected that the cost and the yield of LTPS will be improved. Both integrated driving circuits and pixel switches consist of p‐type TFTs.

The driving circuits are designed to have large immunity to the variation of TFT characteristics and to operate with low power consumption. It is shown that the long life time of panel is guaranteed by acceleration experiments. 10.4 XGA and 12.1 XGA panels have been fabricated and characterized.

Authors: Bunning Timothy J. , Natarajan Lalgudi V. , Sutherland Richard L. , Tondiglia Vincent P. 
Published: January 2005

AbstractHolographically formed polymer dispersed liquid crystals (H‐PDLC) films show excellent promise in the development of switchable transmissive and reflective diffractive optical elements. The use of holographic photopolymerization allows for the development of spatially periodic gratings of nano‐scale sized LC domains. Reflection gratings exhibiting blue, green or red colors can be routinely fabricated and electrical switching has been demonstrated. Reflective H‐PDLCs have been investigated in terms of their electro‐optical performance parameters and their potential as a viable display system. These films exhibit low switching fields, high contrast ratios, high transmission in the on and off states and fast switching speeds on the order of microseconds. The state of the art performance levels and existing challenges in this new technology are broadly discussed.
