P-202: High Transmittance LC Pixel Design for Multi-View 3D Mobile Display

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.

32.3: Liquid Crystal Panel for High Efficiency Autostereoscopic 3D Displays

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.

68.3: An Advanced Transflective TFT LCD using Dual Thickness Color Filter

A new advanced color filter has developed for applying a series of transflective LCDs. It doesnt only make the same color gamut in both transmissive and reflective display modes, but also increase more than 30 % of reflectance ratio from the ambient light. This special color filter structure has thinner color resister layer on reflective area than on transmissive area was called dual thickness color filter (DTCF). An irregular diffraction photolithographic (IDP) exposure technology and new color resister material were developed in order to produce this advanced color filter.

39.2: Distinguished Paper: Novel Single Gap TRLCD with High Reflective Image Quality

The transmissive and reflective gamma curve incongruence is a serious issue for single gap TRLCD. ACC (Advanced Capacitor Coupling) technology has been developed to make the reflective gamma curve similar to the transmissive gamma curve. The threshold voltage and slop of reflective gamma curve are well controlled. The cross-talk issue due to electrical coupling of data line is also solved by a new electrical shielding structure. An improved array process is used to reduce manufacturing cost and increase array throughput. with ACC Tech., the TRLCD can have both simple structure and good transflective optical performances.
