Video moire patterns frequently appear on high-resolution CRTs as a result of interference between the video signal pitch and shadow mask aperture pitch. The moire deteriorates CRT picture quality significantly and must be reduced. The video moire patterns are successfully reproduced by simulating a small-scale luminance distribution and also by taking into consideration the visual characteristics of human eyes. Moire visibility is quantitatively evaluated by a use of moire contrast.

In the direct drive laser fusion, the smoothness of the intensity pattern of each beam has been improved by the use of the random phase plate. However an intensity distribution of the whole beam in a far field region consists of speckles due to random interference. We are investigating the polarization control for the instantaneous speckle smoothing to overcome this problems. To smooth the speckles using polarization control, we need a laser beam consists of two components of which polarization direction are orthogonal to each other. We used a half wave plate array of segmented nematic liquid crystal. We have demonstrated the alignment control of liquid crystal using photoisomerization induced by polarized UV laser to fabricate the PCP with the nonrubbing method. The speckle contrast was reduced by a factor of 30%.

We optimize the curing condition of UV curable liquid crystal (LC) to improve the transmittance after polymerization. The cured LC microlens and optical waveguide are fabricated using the UV curable LC under the optimized curing condition and thier optical performances are confirmed. Relatively good focusing properties can be obtained in the cured LC microlens. A scattering loss is estimated to be 23dB/cm in the cured optical waveguide.

Linear Photo-Polymerisation of Polyvinyl Cinnamate (PVC) photopolymer acts as an optical aligning layer inducing orientation in adjacent liquid crystals. We have promoted the homogeneous as well as homeotropic alignment on PVC substrates under different experimental condition. We attribute the different anchoring direction in different experimental condition to the morphology of the polymer surface. From the observation we anticipate that PVC as an optical aligning layer follows the Friedel-Creagh-Kmetz rule.

A light amplification device based on hybridization of organic electroluminescent diodes and photoresponsive perylene pigment films was reported. Amplification gain of photon conversion from red to red reached 25-folds with the assistance of large photocurrent multiplication phenomenon in perylene pigment films. Light up-conversion from red to green and optical switching behavior caused by feedback of output-light to the photoresponsive layer were also demonstrated.

We synthesized three kinds of diamine derivatives as hole transport layer, is higher luminous efficiency of EL devices made by using TPD2 and TPD3 than that made by TPD. TPD4 has higher glass transition temperature than TPD, but the mobility of TPD4 became lower than that of TPD.

Many studies have concentrated on the decrease in a-Si defect density. However, several a-Si image sensor, such as the 2M-pixel charge coupled device (CCD) image sensor, suffer from the following problem : (1) a decrease in defect density causes an increase in reverse biased current. Therefore, we conducted a trial to calculate the electric field around the edge of the electric field concentration at the edge of the electrode, and (2) the electric field concentration was improved by optimizing shape of the electrode edge. In addition, we confirmed that relaxation of the electric field concentration was observed in the prepared sample.

It is well known fact that a high-luminous efficiency is available if a DC PDP positive column cells can be operated in low current region. But some trials are failed because of difficulties on the operation. This report describes a new positive column cell PDP which has a high efficiency in the operation. A cell has a cathode faced perpendicular to the discharge pass which is parrallel to the front and rear glasses. This PDP is drived in DC-mode memory methods. A TV picture is displayed on the PDP. DC mode memory method is useful for avoiding false outline disturbance in moving picture.

A new autostereoscopic display with a time-divided backlighting system has been developed. We have improved the alignment of optical devices, and overcome the disadvantages of A.R.L.Travis's method, that is, optical cross-talk, and the impossibility of the application to a large display. Our method requires a high-speed LCD, but the resolution of the LCD is not as high as that of a lenticular 3-D display.
