Viewing angle controllable liquid crystal display with high transmittance

Liquid crystal display devices with high transmittance and wide viewing angle

Viewing angle controllable displays with a blue-phase liquid crystal cell.

We demonstrate a controllable viewing angle liquid crystal display (LCD) using an inserted blue-phase liquid crystal (BPLC) cell. The BPLC layer functions as a tunable positive C-film or a negative C-film, depending on whether the employed LC has a positive or negative dielectric anisotropy. Therefore, the viewing angle of the LCD panel can be controlled continuously by the applied voltage of t...

6-2: Inverse Four Domain Twisted Nematic Liquid Crystal Mode for High Transmittance and Wide Viewing Angle Characteristics

In this paper, we fabricated the inverse four domain twisted nematic liquid crystal cell using stacked vertical alignment layer on planar alignment layer for strong azimuthal anchoring energy. That makes possible twist structures under applied voltage without chiral-dopant, as a result, high transmittance and wide viewing angle could be revealed.

Continuous viewing angle-tunable liquid crystal display using temperature-dependent birefringence layer.

We demonstrated a continuous viewing angle controllable liquid crystal display (LCD) adopting a thermally variable retardation layer (TVRL) using nematic liquid crystal with transparent electric-heating lines to control temperature. The simulated and experimental results of the proposed LCD show continuous and symmetric viewing angle characteristics by tuning the retardation of TVRL using Joule...
