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.
A 3D architecture which exploits proximity projector array to project tiled image of low magnification ratio from microdisplays has been proposed as a solution for large screen and high resolution spatial multiplex autostereoscopic display. with descent lenticular and projection optics design associated with dedicated pixel mask, the proposed 3D configuration shows low crosstalk between viewing zones and demonstrates a potential alternative to increase pixel count for wide view and high resolution 3D displays.
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 ∼9 ° to ∼30 ° compared with conventional multi‐domain VA.
