The 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.

We 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 gate

We presented here a novel liquid crystal display - non-compensated super-twisted nematic LCD (XSTN). XSTN, specially designed for its twist angle, the parameters of liquid crystal mixture, the product of cell thickness and the birefringence, the direction of its polarizer, etc., showed a good electro-optic performance. The theoretical predictions on the brightness, the contrast, the dispersion and the multiplexing ability, etc. were confirmed by experiments.

A 10.4-inch reflective type TFT-LCD with 640×480 pixels using the recently developed mixed-mode twisted nematics (MTN) cell is demonstrated. For the direct-view applications, this display exhibts very high contrast which is more than 30 to 1. The viewing cone is more than 40°without gray-scale inversion. The colorimetry performance is as good as a transmissive TN-LCD. The response of this display is less than 20 ms.

TN 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.

The E-O Characteristics of polymer dispersed liquid crystal (PDLC) are affected strongly by refractive index-matching in field-ON state. Those factors causing index-mismatching have been described in this paper. A PDLC film with a high transparency in ON state is prepared by choosing proper prepolymer/LC material and cured at a suitable rate.

Time-dependent behabior of various plasma variables of an AC-PDP cell such as the electron temperature, density, densities of ions and excited species and surface charge distribution are obtained by solving the time-dependent, 2-dimensional multi-fluid equations. It showed that the wider the sustain electrode, the bigger the surface charge variation in one period which implies a more stable sustainment can be obtained with wider sustain electrodes.

40インチを超かる高精細AC-PDPの開発を行っている。一般にPDPの解像度を上げると維持電極幅が狭くなるため、輝度が減少する。輝度が減少しないように維持電極幅を広くすると隣接ラインのとの距離が狭まり、隣接ラインとの間で放電が生じ、維持電圧マージンが急激に減少する。我々は、この現象が維持電圧バルスの波形条件に強く依存していることを見出し、維持電圧パルスを制御することによって、隣接ラインとの誤放電を防いだ。

A cathode emission proflier based on anode-hole scanning method has been developed, which reveals emission density distrlbution and local emission characteristics in a cathode surface. 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.

Metal contamination free Poly-Si TFT's could be fabricated on the glass substrate at 450℃ by Metal Induced Lateral Crystallization (MILC) method. The channel area was laterally crystallized from the source and drain areas, where the thin film of nickel was deposited in a self aligned manner. Electrical activation of the source and drain could be achieved by annealing at 450℃ after the ion mass doping of phosphorus. The N-channel TFTs showed the mobility of 〜53cm^2/Vs, and the on/off current ratio was higher than 10^6

We propose a novel mixed dual beam laser crystallization method, where two different pulse lasers with different wavelength successively irradiate on Si film. Thermodynamic computer model of laser annealing is used to analyze the solidification characteristics of Si film annealed by the novel method. The simulation results demonstrate that the novel method is a promising one to reduce solidification velocity effectively.

Isothermal 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.

The concept of effective density of interface states at a-SiNx : H/a-Si : H interface has been used to analyse the performance of a-Si TFT theoretically, such as field effect, flat band voltage, subthreshold characteristics, as well as experimental research on a-Si TFT. The transfer characteristics of various a-Si TFT and the sub-threshold characteristic parameter S, with different fabrication conditions, have verified the conclusions drawn up from the theoretical analysis in this paper.

A compensation layer was inserted in between active layer a-Si : H and passivation layer a-SiNx of a-Si : H TFTs in order to improve the quality of the interface. The dependence of the performances of the a-Si : H TFTs with the rf power of the hydrogen plasma treatment were experimentally investigated. The characteristics of the a-Si : H TFTs is improved by using an optimum rf power and introducing a special buffer layer.

We also fabricated a 10-in. diagonal ZnS : Mn thin-film electroluminescent (TFEL) panel using newly developed a series of sputtering and electron beam apparatus which could deposit these films sequentially. The average luminance of this 10-in. diagonal TFEL panel was 1900 cd/m^2,at 40 V higher than threshold voltage with 1K Hz sinusoidal wave excited.

The polymer poly-p-phenylene-vinylene (PPV) was prepared and constructed into single layer thin film electroluminescent devices as ITO/PPV/Al. AC electroluminescence was observed for the first time on our PPV single layer thin film EL devices at frequency 50Hz from 4V to 15V. The emission spectra were recorded. Light emission intensities in different ac voltages were measured. It suggested that there were other kinds of light emissions besides the injection and recombination of two kinds of charges in emitting layer.

We 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.
