42.4: Characterization of Electrochemically‐Active Defects in Si‐Film Laser‐Crystallized with Directional SLS by Measuring the Stress Release during Secco Etching
Authors: Sasaki Nobuo , Kitahara Kuninori , Yamamoto Kenichi 
Published: August 2010

AbstractIt has been verified that the crystal quality of directional SLS film achieves a position between those of ELC and CLC. The SLS film contains some electrochemically‐active in‐grain defects, which is hard to be passivated by hydrogen; this kind of defects are not observed in CLC nor ELC films.
45.3: Quasi‐Impulsive Driving for High‐Speed Operation of a Homogeneous Aligned LC Cell with 3‐Electrode Structure
Authors: Kim Ki‐Han , Baek Jong‐In , Kim Jae Chang , Yoon Tae‐Hoon 
Published: August 2010

AbstractWe propose a method for quasi‐impulsive driving of a homogeneous‐aligned liquid crystal cell by using 3‐electode structure. At the beginning of every frame, liquid crystals are momentarily vertical‐aligned, followed by twist deformation to show a bright state, by which gray to gray as well as turn‐on and turn‐off responses can be improved. In comparison with conventional driving scheme applicable to 2‐electrode cells, we demonstrate by experiment that a liquid crystal cell with the 3‐electrode structure can be operated as an impulsive‐type display by the proposed method.
46.1: Invited Paper: Exciton Induced Chemical Reactions in Organic Light Emitting Devices
Authors: Scholz Sebastian , Meerheim Rico , Lüssem Björn , Leo Karl 
Published: August 2010

AbstractWe show that chemical reactions are the major intrinsic degradation mechanisms in high‐performance organic light emitting devices. The resulting reaction products create deep traps, non‐radiative recombination centers, and luminescence quenchers in organic devices. The main reaction pathways, induced by excitons are fragmentations, oligomerizations, and complexations. We show that laser‐desorbed mass spectroscopy can be used as a predictive method to compare different materials in terms of the expected lifetime for OLEDs.

Authors: Murata Hideyuki , Matsushima Toshinori 
Published: August 2010

AbstractIn this paper, we have investigate that the degradation mechanism of OLEDs using Alq3 and FIrpic as emitting materials. for the Alq3 device, ultra‐thin layers of MoO3 significantly enhance the device durability. The optimized MoO3 thickness was 0.75 nm, realizing the lowest voltage and the longest lifetime. We found that the device stabilities strongly depend on the process pressure during the device fabrication. In both fluorescent and phosphorescent emitting materials, the devices fabricated under UHV conditions demonstrated excellent long‐term stabilities.

52.4L: Late News Paper: Continuous Control of Spatially‐Homogeneous Nematic Pretilt Angle Using Mixtures of Two Polyimide Alignment Materials
Authors: Lee Ji‐Hoon , Clarke Christopher M. , Rosenblatt Charles , Kang Daeseung 
Published: August 2010

AbstractWe show that certain mixtures of polyimides that induce planar and vertical alignment do not microphase separate, yet provide continuous control of pretilt angle vs. their relative concentration. The results, which demonstrate that variable pretilt does not require microphase separation, are explained by the addition of fourth order terms to the usual Rapini‐Papoular surface energy.

Published: August 2010

AbstractPower efficiency demands on mobile displays are increasing rapidly, as new multimedia services and applications are being adopted by users. Diffractive backlights and electrowetting displays have been proposed as some of the solutions to solve the poor efficiency of current mobile display systems. In this study, an electrowetting display was coupled with a pixelated, diffractive becklight light guide plate. This is to our knowledge the first time when a pixelated, diffractive backlight has been demonstrated in conjunction with an actual display. The results of the study show that the backlight and display panel need to be optimized as a system in order to obtain an applicable module for mobile use.

57.1:Invited Paper: Key Requirements for High Quality Picture‐Rate Conversion
Authors: Cordes Claus Nico , de Haan Gerard 
Published: August 2010

AbstractPast LCD‐TV generations suffered from a poor motion portrayal, causing the blurring of moving objects. Hence, various techniques have been implemented to improve their motion portrayal, of which the widespread introduction of motion compensated picture‐rate conversion in TV systems is an essential part. However, a careful design of such algorithms is critical, as otherwise very annoying artifacts may decrease their value. In this paper, we will give an overview of the key requirements for high quality motion‐compensated picture‐rate conversion, as implemented in state‐of‐the‐art system‐on‐chips, and visually illustrate the impact of individual measures on picture quality.

Authors: Kurita Taiichiro 
Published: August 2010

AbstractMotion‐image‐quality of LCD‐TVs and TV system is discussed by dynamic spatial frequency response. Smaller temporal aperture or higher frame‐rate can improve dynamic response, but an increase of motion velocity easily cancels the improvement. A consideration to decide optimum temporal aperture and frame‐rate is described.

Published: August 2010

AbstractThe inability for controlled large‐scale assembly of single‐walled carbon nanotubes (SWNTs) represents the biggest obstacle for application of this superior nanoelectronic material. Our aim here is to develop not only a reliable approach to deposit SWNTs uniformly over a large area from solution, but also leads to a SWNT network with tunable reproducible topological and electronic properties. By controlling nanotube network characteristics with substrate surface chemistry, we demonstrate reproducible transistors over large scales from solution, which is key for integration onto disposable and flexible plastic surfaces.

Published: August 2010

AbstractWe have been developing retardation‐controlled polypropylene‐based films with additives. We propose new optical films having Re value (in‐plane retardation) around 100nm, or less 20nm. These films show high durability as optical properties under certain conditions. The low Re value film can be used for protection films of LCD's polarizer, and the high Re value one can be used for retardation films of VA and other modes of LCD.

Authors: Arkhipov Alexander , Park Kyongtae , Lee Baek‐woon , Kim ChiWoo 
Published: August 2010

AbstractRGBW AMOLED panel, compare to the RGB panel, has lower power consumption and current stress and as result — bigger life time. Using special algorithms and RGB subpixels (as additional white) permits to increase brightness of this panel up to 2 times. At the same time it's very important to keep panel current at permissible range. We propose an algorithm, what permits to increase brightness of the RGBW AMOLED panel and limit its summary current at the same time.

65.1: Invited Paper: Amorphous Silicon TFT's with 100‐Year Lifetimes in a Clear Plastic Compatible Process for AMOLEDs
Authors: Sturm James C. , Hekmatshoar Bahman , Cherenack Kuni , Wagner Sigurd 
Published: August 2010

AbstractWe demonstrate critical elements of a‐Si technology on clear plastic for flexible AMOLED applications. First, we show that a‐Si TFT's with gate voltages under 5 V provide sufficient current for OLED pixel brightness of over 1000 cd/m2, with minimum geometries (W/L = 1)for 100 μm × 100 μm pixels. Critical to this result is a clear plastic with the combined properties of high transparency, glass transition temperature in excess of 300 °C, and low coefficient of thermal expansion. Second, we show that by engineering the a‐Si TFT stack, under the bias conditions for pixel operation, the “half‐life” of the TFT (defined as the time for the current to fall by 50% in DC operation) is 10 years for a 280 °C process on clear plastic, and at least 100 years for 300 °C. This is several orders of magnitude higher than that of common a‐Si TFT processes and in general larger than the lifetimes for the 50% decay of the luminescence of the OLED's themselves. Finally, we provide a framework demonstrating the tradeoff between drive current and TFT stability.
P‐149: Anode Electrode of Al‐Ni Alloy Film Directly in Contact with ITO for Top‐Emitting OLEDs
Authors: Kugimiya Toshihiro , Yoneda Yoichiro , Kusumoto Eisuke , Ochi Mototaka , Goto Hiroshi , Nakai Junichi 
Published: August 2010

AbstractA bottom anode with high reflectivity is one of the most important materials for top‐emitting OLEDs. As an anode electrode, stacked ITO/Al‐Ni alloy‐based films, as opposed to conventional stacked ITO/Ag films, were investigated for the first time. It was found that the direct contact technique of the Al‐Ni alloy‐based film with the ITO film using a film annealing process was applicable for OLEDs, as in the case of LCD interconnections that have already been developed by the authors. It was thus concluded that the Al‐Ni alloy‐based films were suitable materials for the anode electrode of OLEDs. They are a better choice than Ag film, due to their low material cost and ease of production of large‐area sputtering targets for large‐Size OLED‐TVs.
Polyamidoamine dendrimer and dextran conjugates: preparation, characterization, and in vitro and in vivo evaluation
Authors: Shrivastava Prabhat , Singh Royana , Shrivastava Sushant 
Published: August 2010

AbstractAmide and ester conjugates of aceclofenac with polyamidoamine (PAMAM-G0) dendrimer zero generation and dextran (40 kDa) polymeric carrier, respectively, are presented. The prepared conjugates were characterized by UV, TLC, HPLC, IR, and 1H NMR spectroscopy. The average degrees of substitution of amide and ester conjugates were determined and found to be (12.5 ± 0.24) % and (7.5 ± 0.25) %, respectively. The in vitro hydrolysis studies showed that dextran ester conjugate hydrolyzed faster in a phosphate buffer solution of pH 9.0 as compared to PAMAM dendrimer G0 amide conjugate, and followed the first order kinetics. No amount of the drug was regenerated at pH 1.2 in simulated gastric fluid. The dextran conjugate showed short half-life as compared to the PAMAM dendrimer conjugate. Anti-inflammatory and analgesic activities of the dendrimer conjugate were found to be similar to those of the standard drug. Results of chronic ulceroginic activity showed deep ulceration and high ulcer index for aceclofenac, whereas lower ulcer index was found for the PAMAM dendrimer and dextran (40 kDa) conjugates. Experimental data suggest that PAMAM dendrimer and dextran (40 kDa) can be used as carriers for the sustained delivery of aceclofenac along with a remarkable reduction in gastrointestinal toxicity.
Photophysical properties of novel ferrocenyl quinoline derivatives with red emission in solutions and polymeric matrices
Authors: Yang Dingqiao , Zhang Haifeng , Wang Qianming 
Published: August 2010

AbstractA group of novel 2-ferrocenyl quinoline derivatives was designed and their photophysical properties were thoroughly studied. UV-VIS and steady-state fluorescence spectra show that these compounds gain energy in the ultra-violet region and give red emissions in different organic solvents. More importantly, two transparent hybrid thick films composed of 2-ferrocenyl quinoline and poly[1-(methoxycarbonyl)-1-methylethylene] (poly(methyl 2-methylpropenoate, (poly(methyl methacrylate), PMMA), or poly[2-hydroxyethyl 2-methylprop-2-enoate] (poly(2-hydroxyethyl methacrylate), PHEMA) matrix were successfully prepared. Both films showed red emissions of ferrocenyl quinoline chromophore and the ideal composition of luminescent species is 10−6 M PMMA and 10−5 M PHEMA, respectively. SEM graph exhibited ferrocenyl quinoline molecules dispersed very homogenously within the above polymer hosts.

Published: August 2010

AbstractChemical compositions of 16 Artemisia herba-alba oil samples harvested in eight East Moroccan locations were investigated by GC and GC/MS. Chemical variability of the A. herba-alba oils is also discussed using statistical analysis. Detailed analysis of the essential oils led to the identification of 52 components amounting to 80.5–98.6 % of the total oil. The investigated chemical compositions showed significant qualitative and quantitative differences. According to their major components (camphor, chrysanthenone, and α- and β-thujone), three main groups of essential oils were found. This study also found regional specificity of the major components.
Biological buffered saline solution as solvent in agar-carbomer hydrogel synthesis
Authors: Rossi Filippo , Perale Giuseppe , Masi Maurizio 
Published: August 2010

AbstractThe role of phosphate buffer saline solution (PBS) was investigated here as a solvent in the polycondensation synthesis of an injectable agar-carbomer based hydrogel, a promising new material specifically intended for regenerative medicine applications. The effects of PBS, with respect to standard distilled water (DW), were quantitatively assessed. Experiments were performed both from physico-chemical and biological points of view. Titration showed higher stability due to the presence of the buffer solution; ESEM analysis confirmed its distribution along the polymeric fibers and infrared spectroscopy showed the consequent anionic nature of the polymeric network. This electrostatic nature of the matrix was confirmed by mass equilibrium swelling data performed at different pH values of the swelling medium. A very relevant role of the solvent was observed also with respect to cell housing inside such hydrogels: living cell counts showed a high amount of cells surviving the latency period of encapsulation in hydrogel when PBS was applied while only very few survived in a deionized water based gel. Obtained data allowed a novel understanding of the causeeffect cascades of all observed phenomena which suggest the PBS fundamental role both in fine control of hydrogel preparation and in material tuning according to the specific needs of different target tissues; the latter being a feature of primary importance when applying hydrogels as cell carriers in regenerative medicine applications.
