The methods of pixel arrangement for autostereoscopic liquid crystal displays based on conventional vertical parallax barriers are summarized. A novel method of pixel arrangement for autostereoscopic liquid crystal displays based on step parallax barriers is proposed. The pixel arrangements are given for different inclined angles of parallax barriers and different column numbers of images. A demo of the autostereoscopic liquid crystal display using the new method of pixel arrangement presents very good stereo images. The results help to solve the process, storage and transmission of stereo images of autostereoscopic liquid crystal displays based on parallax barriers. [ABSTRACT FROM AUTHOR]

Here in this investigation, the molecules exhibiting photoisomerization in solutions is also photostable is observed. On the other hand molecules not showing photoisomerization behavior in solutions is not shown such kind of stability. Surprising behavior in which after writing laser is turned off, there is going to be increase in phase retardation (or order parameter) which is under deep consideration. Detail investigation is in progress to reveal the behavior of chemical structures when light is shined on them. Proposed investigation is crucial for selecting suitable azo dyes for photoalignment studies and also for many commercial applications which depends on many factors like stability, order parameter etc. [ABSTRACT FROM AUTHOR]

Periodical groove structure was formed on the substrate surface by copying the structure on the grating film on the market to the photo curable resin coated on the substrate surface. And then, the substrate surface with groove structure was rubbed along the direction perpendicular to the groove. Alignment of LC on such substrate surface was experimentally investigated. And the occurring of pre-tilt was confirmed. In a cell constructed using such substrate and, for the other side, the substrate treated by a vertical alignment material, distinctive domains with different orientation direction were observed. This suggests us that the bistable alignment property can be adapted on the substrate surfaces by the method above mentioned. [ABSTRACT FROM AUTHOR]
