We successfully developed a 3D liquid crystal display (LCD) modeling program and applied the program to modeling the single-domain vertical alignment (VA) and intrinsic fringe field controlled multi-domain vertical alignment (IFF MVA) LCDs. Our study showed that proper and stable IFF MVA operation was obtained in the microdisplay geometry but not in the direct-view geometry, whereas regular VA operation was obtained in the direct-view geometry but not in the microdisplay geometry.

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]

In the bistable chiral splay nematic (BCSN) mode, the splay and π twist states are used for the two stable states. The transition between the memory states accompanies the motion of the disclination line, due to the topologically inequivalent from each other. The switching time is consistently coupled with the propagation velocity of the disclination line, which strongly depends on the amplitude of the applied voltage. In this paper, we demonstrate the gray scale of BCSN liquid crystal display (LCD) by the control of the domain density of the splay and twist states during the transition process.

The cholesteric filters can improve the efficiency of light use when it is applied to a reflective mode. They reflect circularly polarized incident light of the same handedness as the cholesteric helix and transmit the one having the opposite handedness. The transmission bandwidth depends on the helical pitch. In order to widen the bandwidth, we synthesized new cholesteric liquid crystal molecules containing the active reaction moeity to UV light and investigated the various UV treatment methods to broaden the bandwidth of the cholesteric filters. There was appears that the band broadened about 200  nm by using the photo-mask. It is caused of a factor as a consequence of UV-curing when the cholesteric pitch changes locally by using the mask.

The in-plane switching(IPS)mode liquid crystal display(LCD)panels with different pretilt angles and alignment directions are prepared, and their electro-optical properties and viewing angle characteristics are examined. The examination shows that parallel alignment with a pretilt angle of about 3∗brings about a panel with very wide viewing angle characteristics and little color shift in relation to that viewing angle. The pretilt angle of 3∗can be achieved by conventional alignment film for Twisted Nematic mode LCD, and higher productivity of IPS-mode LCD panels in consequently expected. [ABSTRACT FROM AUTHOR]

UV-transparent nematic liquid crystals synthesised specifically for use as components of nematic mixtures for the Photoluminescent Liquid Crystal Display (PL-LCD) are reported. These polar and apolar nematic liquid crystals do not possess conjugated phenyl rings or cyano-groups. Where two phenyl rings are present, they are separated by a non-conjugated linking group, so that they do not absorb in the visible or the near ultra-violet. Polar and apolar nematics have been combined to generate UV-transparent nematic mixtures of positive dielectric anisotropy for use in TN-PL-LCDs and STN-PL-LCDs transmitting monochromatic UV light at 365 or 390 nm.

We propose in-cell LCD films with a function of compensation films and alignment layers. The processes used to create these functions exclude mechanical contact with the films. There is proposed approach decoupling retardation and liquid crystal alignment. This approach is employed to realize different combinations of retardation and alignment properties.
