Various methods to improve the image quality are quantitatively compared. Motion image disturbance on an AC-PDP has been simulated on a computer by using a simple eye-tracking model to simplify the relation between the moving image on the AC-PDP, light emission from the PDP, and the captured image with disturbance on the retina. From the simulation results, we can easily choose an effective light emission scheme to improve the moving image quality of an AC-PDP.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

It was found that the well-known optical bounce phenomenon which was originally found in the twist nematic cells, also appears in the chiral-homeotropic cells. The field induced backflow causes this optical bounce and it may influence the dynamic response of the cell. In this paper, we will present the experimental data and use a simple model based on Erickson-Leslie-Parodi theory to explain the optical bounce phenomenon appearing in the homeotropic to planar state transition.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

Significant reduction of mobility was observed in short channel devices due to parasitic resistance. Based on our analysis of the Rp requirement for high-performance short-channel LT poly-Si TFTs, to avoid significant degradation in the mobility for the mobility larger than 300 cm/sup 2//Vs, it is necessary to keep Rp below 200 ohm.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

The parameters of the compensation films have been optimized by computer simulation and these results showed that the films could minimize the oblique leakage light of the dark state and improve the viewing angle efficiently.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

It will be shown that the apparent threshold voltage (V/sub t/) of the MILC TFTs is affected by the presence of these MILC/MIC grain boundaries (MMGBs) at the edges of the transistor channels. Furthermore, V/sub t/ can be reduced either by eliminating the MMGBs from both the source and drain junctions or by hydrogen passivation of the traps in the MMGBs.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

These displays are suitable for use in head mount and projection display systems. A particular advantage of the technology is that it enables the design and production of low cost single channel color systems which are predicted to be both cost and performance competitive with existing CRT products.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

In the second part, the generalized Jones matrix was used to simulate for the optical reflectance through the LCD with the 2D director configuration obtained from the first part. This optical modeling was applied to analyze optical reflectance of small pixels in reflective mixed-mode twisted nematic (MTN) cells on silicon substrate.
