Using a 6-view 3D mobile display, a modified LC pixel mode that increases transmittance and brightness uniformity for each viewing zone plus pixel electrode physical re-configuration capable of increasing Aperture Ratio were investigated The pixel mode utilized was the single-domain VA. In the modified case of the single domain VA mode with the reconfiguration, it was observed that by optimizing each pixel, the transmittance of the single-domain VA could be improved by more than 24% at relatively wide, mobile display, viewing angles from similar to 9 degrees to similar to 30 degrees compared with conventional multi-domain VA.

This paper proposes a configuration of liquid crystal panel for 3D application with the viewing angle property of each pixel varied and optimized for the direction to the corresponding perspective view, and the light blocking area of each pixel is located in accommodation to the lenticular and barrier design. The simulation result shows better performance on efficiency and cross talk comparing to the similar 3D display using traditional liquid crystal panel with the same pixel count and pixel Size.

An autostereoscopic display with parallax barrier attached onto a liquid crystal panel suffers from the trade-off between brightness and crosstalk. One approach for making improvement by modifying the layout of light blocking components, such as thin film transistor, storage capacitor, and protrusion, in the liquid crystal pixel has been proposed. Ray tracing simulation shows that the aperture of the slanted barrier can be significantly increased, hence increasing efficiency, while keeping the same crosstalk level if those light blocking components can be shifted to the corner of the pixel. A six-view 2.83 in. (7.19 cm) prototype has shown improvement on both brightness and crosstalk compared to its counterpart using a traditional liquid crystal panel, which demonstrates an effective approach for a high-efficiency barrier-type autostereoscopic 3D display with a liquid crystal panel.
