Published: January 2009

AbstractA touch screen panel (TSP) embedded 12.1‐inch LCD employing a standard a‐Si:H TFT‐LCD process has been successfully developed. Compared with conventional touch screen panels, which use additional components to detect touch events, the new TSP exhibits a clearer image and improved touch feeling, as well as enabling the LCD module to provide the sensing data through the driver ICs with an integrated readout function. Our new internal digital switching TSP can be fabricated with low cost because it does not require any additional components compared to a standard a‐S:H TFT LCD.

Authors: Sarayeddine Khaled , Benoit Pascal , Shemo David M. 
Published: January 2009

AbstractRear Projection TV (RPTV) offers low cost and high definition images, but suffers from inadequate form factor for the cabinet design. Slim RPTV design with small depth and low chin (distance from stand to image lower edge) are available and offer a second chance for RPTV to compete in the battle of flat screen displays. for slim RPTV with a low‐cost, refractive Fresnel screen, the angle of incidence of the light beam reaches 70° and induces large Fresnel losses. In order to correct this issue and to increase brightness uniformity and light flux, we designed a space variant retarder (SVR) to be located in the imaging arm of the Slim RPTV. This paper describes the concept and the experimental results.

A planar‐waveguide configuration improves performance of solid‐state green laser dramatically. The laser consists of essential minimum three devices (a pump LD, a planar‐waveguide Nd:YVO4 and a planar‐waveguide PPMgLN). Output green peak power of 11.4‐W with the corresponding electrical efficiency of 21% is demonstrated. In addition, temperature insensitive features are also proved. The size of developed laser module is as small as 5cc. We believe this laser is the most suitable green laser light source for laser TV at present.

We utilized RGB evaporation process with fine metal mask. The novel delta pixel arrangement results in increased aperture ratio and wider FMM process window. The advantage of SLS process will be discussed.

Published: January 2009

AbstractTo reduce power consumption and improve image quality including contrast ratio and color gamut, LED backlight units (BLUs) consisting of many small blocks in 2‐dimensional space are implemented. Either white‐gray‐level luminance or color is controlled by the local dimming LED BLU. However, such a BLU can induce various recognizable artifacts. A method is proposed for exact block luminance calculation along with a new algorithm to correct local dimming artifacts. A new concept of color classes has also been developed to achieve extremely wide color gamut and to minimize color related artifacts.

AbstractThe recent advances in LCD panel refresh rates have created a need for high quality frame rate conversion (FRC). Although the FRC algorithms have been developed and utilized in many applications, these techniques are not mature. In order to achieve the next level of FRC quality, many issues must be addressed. In this paper, we discuss the main issues in most of the existing FRC techniques, and propose some directions and solutions to solve them.

Authors: Matsueda Yojiro , Shin Dong‐Yong , Chung Ho‐Kyoon 
Published: January 2009

AbstractThough AMOLED display has been expected as the next generation ideal flat panel display because of its excellent image quality, the AMOLED market has been still limited. This means that AMOLED has not had sufficient competitiveness with LCD yet. There are two critical problems for AMOLED to overcome to compete with LCD. One is Mura problem caused by TFT characteristics deviation in the backplane and the other is short life time of image sticking. In this paper, we will review various approaches to overcome these two critical problems and discuss the practicality of the methods.
Kinetic studies on leucite precursors
Authors: Mrázová Martina , Kloužková Alexandra , Kohoutková Martina 
Published: January 2009

AbstractKinetic studies were performed on two types of leucite precursors. These precursors were prepared using a hydrothermal method at 150°C; the reaction time was 1.5 hours. In order to obtain precursors having different amounts of seed the molarity of KOH was changed. These intermediate products were subsequently calcinated from 5 minutes to 72 hours at temperatures of 850°C, 900°C, 950°C, 1000°C and 1050°C. The crystallinities of the powders were calculated by X-ray diffraction analysis. The crystallization curves for the synthesis of leucite exhibited a typical sigmoidal characteristic. Using different kinetic equations it was found that the Avrami-Eroféev model is the most appropriate to describe the experimental data. Using the Avrami-Eroféev model n reaches an average value of 2.9 which is connected with the three-dimensional growth of nuclei. The calculated activation energy of crystallization of leucite was 385 kJ mol-1 for non-seeded precursors and 246 kJ mol-1 for seeded precursors, respectively.
Scattering of an arbitrarily oriented dipole field by an infinite and a finite length PEMC circular cylinder
Authors: Illahi Ahsan , Naqvi Qaisar 
Published: January 2009

Abstract
Electromagnetic scattering from an infinite and a finite length PEMC circular cylinder, illuminated by an arbitrarily oriented dipole, is investigated theoretically. An electric dipole as a source of excitation is considered first, and then a magnetic dipole as a source of excitation is treated. In contrast to the case of an axially directed dipole, it is shown that no additional terms are needed to incorporate the cross-polarized component of the field for the case of radial and circumferential dipoles. Numerical verifications are presented to verify the validity of derived results and numerical code by comparing results with the published literature.

Infrared and Raman investigations of two phases of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) based organic conductors with the same CF3CF2SO3− anion: β′-(BEDT-TTF)2CF3CF2SO3 and δ′-(BEDT-TTF)2CF3CF2SO3, are shortly reviewed and compared with the most typical infrared properties of the family of (BEDT-TTF)2RR′SO3 organic conductors, where R = SF5, CF3, and R′ are CH2, CF2, CHF, CHFCF2, and CH2CF2. The role of the molecular structur and spatial organization of the counterions is discussed.
Activation of the heat shock response in a primary cellular model of motoneuron neurodegeneration-evidence for neuroprotective and neurotoxic effects
Authors: Kalmar Bernadett , Greensmith Linda 
Published: January 2009

AbstractPharmacological up-regulation of heat shock proteins (hsps) rescues motoneurons from cell death in a mouse model of amyotrophic lateral sclerosis. However, the relationship between increased hsp expression and neuronal survival is not straightforward. Here we examined the effects of two pharmacological agents that induce the heat shock response via activation of HSF-1, on stressed primary motoneurons in culture. Although both arimoclomol and celastrol induced the expression of Hsp70, their effects on primary motoneurons in culture were significantly different. Whereas arimoclomol had survival-promoting effects, rescuing motoneurons from staurosporin and H2O2 induced apoptosis, celastrol not only failed to protect stressed motoneurons from apoptosis under same experimental conditions, but was neurotoxic and induced neuronal death. Immunostaining of celastrol-treated cultures for hsp70 and activated caspase-3 revealed that celastrol treatment activates both the heat shock response and the apoptotic cell death cascade. These results indicate that not all agents that activate the heat shock response will necessarily be neuroprotective.
Genetic variability and correlation analysis in hybrids of mulberry silkworm, <i>Bombyx mori</i> L. for egg characters
Authors: Ahsan Md Kamrul , Rahman SM 
Published: January 2009

The genotypic variability and correlation coefficients were studied in thirty five hybrid populations for five egg characters. Variations among genotypes were highly significant (P < 0.001). Phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the characters. Of them unfertilized and dead egg percentage showed highest difference between genotypic and phenotypic coefficient of variation suggesting most influence of environment on these characters. Majority of the characters showed high heritability except hatching percentage. Furthermore total number of egg laying per female showed high genetic advance together with high heritability, which indicates the importance of additive gene effect of this character. The genotypic correlations were higher than phenotypic correlation for majority of the characters under study except DEP Vs TEL and DEP Vs UEP. These low phenotypic correlations could be due to a modifying effect of environment and the association of characters at genotypic level. Hatching percentage, blue egg percentage and unfertilized egg percentage showed both positive and negative significant correlation to each other. Therefore, proper attention should be given to these characters specially total number of egg laid by female and hatching percentage in selection programme for genetic gain in Bombyx. mori.
