A New Architecture for High Resolution Autostereoscopic 2D/3D Displays using Free-Standing Liquid Crystal Microlenses

摘要

The trade-offs in design of high resolution (>200ppi) switchable autostereoscopic 2D/3D displays for cell phone applications are described. It is shown that as pixel density increases, LCD counter substrate thickness limits the minimum 3D viewing distance. Free-standing solid phase liquid crystal polymers enable Polarisation Activated Microlenses to deliver autostereoscopic 3D images on VGA resolution displays with 2" diagonal. The solid lenses also improve mechanical ruggedness and facilitate reductions in system thickness. Results obtained with high precision free-standing films indicate added device thickness < 1.1 mm is readily achievable. The components are fabricated with known manufacturing techniques and are compatible with existing LCD and OLED displays.
