In conventional autostereoscopic 3D displays, due to the fact that the pixel designs of the liquid crystal displays were not optimized for 3D displays, the issues of lower brightness and degraded images quality were produced. The major issue is lower brightness with unbalanced brightness between viewing zones. In order to increase image brightness and minimize unbalanced brightness issue, we proposed a pixel layout where blocking light components, such as storage capacitor, was optimized for the parallax barrier to increase the transparent area. Beside, in order to balance the brightness between viewing zones, each pixel has its own transmittance curve which is optimized for specific viewing zone. In the simulation results, the brightness of a parallax barrier 3D display with proposed pixel layout is increased by a factor of 2 compared to that of 3D display based on conventional pixel layout. A 2.83” 6-view 3D mobile display has been demonstrated. The pixel layout with slanted storage capacitor is fabricated, but each pixel still has the same transmittance curve. From the experimental results, the brightness is increased by a factor of 1.6.
