CONFERENCE PROCEEDINGS FREE ACCESSThe IPS mode of LCD has wide viewing angle compared with TN mode, but requires a higher driving voltage to reach a maximum transmittance. The electro-optical properties of IPS mode are complicated and can not be fully revealed by an analytic form. In this letter, the electro-optical properties of in-plane switching mode were analyzed by LC continuum theory to achieve a maximum transmittance at a low operating voltage.View full abstractDownload PDF (420K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe propose the new poly-Si TFT structure which reduces the leakage current effectively employing highly resistive a-Si region in the channel. This new device has partially crystallized active layer, where both edges of channel region adjacent to source and drain are not crystallized and remain a-Si. In the fabrication of the proposed device, there are not additional photo masking steps and misalign problem. Another advantage of the proposed device is increase of aperture ratio adpting the transparent ITO gateView full abstractDownload PDF (530K) -

CONFERENCE PROCEEDINGS FREE ACCESSTN mode liquid crystal used in AMLCDs has poor and asymmetrical viewing angle, especially for vertical viewing zone. We have developed the novel OSR (One-side-rubbing) liquid crystal display to improve the viewing angle. The cell consists of two PI-coated substrates in which one is multi-rubbing and another is non-rubbing. The viewing angle of such a display system has been improved to be about ±40 degrees for vertical view.View full abstractDownload PDF (276K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have been developing the technology for high definition AC plasma display panels over 40-inch diagonals. In general, when the resolution of the PDPs increases, the brightness decreases because the sustain electrodes breadth becomes narrow. When Using wide sustain electrodes in order to increase the brightness, a discharge toward the adjacent line's sustain electrodes occurs and the sustain voltage margin abruptly decreases. We have found that this phenomenon strongly depends on the waveform conditions of the sustain voltage pulses. We have restrained the discharge toward the adjacent line's sustain electrodes by controlling the waveform conditions of the sustain voltage pulses.View full abstractDownload PDF (435K) -

The 411-type impregnated cathodes with O_s-Ru coating for CRT use are studied with this emission profller having a 20 micrometer anode-hole. Several new findings have been obtained particularly in the aging processes and the oxygen gas poisoning and recovery processes, which imply the importance of emission proflle studies in understanding cathodes.View full abstractDownload PDF (397K) -

CONFERENCE PROCEEDINGS FREE ACCESSIsothermal annealing of boron or phosphorus implanted polycrystalline Si_<1-x>Ge_x thin films, with x varying from 0.3 to 0.55 was studied in this paper. In low temperature (<=600℃) annealing, grain boundary segregation causes both the conductivity and the Hall mobility to decrease during extended annealing. The effective activation of phosphorus was less than 20% and decreases with increasing Ge content. Boron activation could reach above 70%. It was also found that Si_<1-x> Ge_x could be oxidized at 600℃ in a conventional furnace even with pure N_2 protection.View full abstractDownload PDF (512K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe describe the fabrication of high-efficiency (>95%) transmission and reflection color holographic filters for use with liquid crystal displays (LCDs). Tricolor (RGB) filters are made in a photopolymer film by selecting the appropriate angle between two interfering plane-wave laser beams from an argon-ion laser. The gratings are then fixed by uniform illumination from a UV light source. This approach is simple and highly versatile and it allows for the custom tailoring of the optical properties of the holographic filters such as the center wavelength, spectral bandwidth, peak efficiency, and viewing angle in order to suit a specific LCD product's performance requirements for color filters.View full abstractDownload PDF (330K) -
