Abstract: We developed a brightness enhancement technology for the parallax type 3D displays. New parallax barrier consists of reflective polarizer and patterned active retarder. Basic operation principle of it is to recycle the light, which is absorbed at barrier in normal parallax barrier 3D. The concept is depicted in Fig.1 (b). The light coming to slit area has the polarization parallel to the transmission axis of reflective polarizer, so that passes through the parallax barrier layer onto the TFT-LCD. On the other hand, the light coming to barrier area has the polarization perpendicular to the transmission axis of reflective polarizer, so that reflects from the parallax barrier layer, and come to the BLU, and reflect from BLU. If it meets the slit area on the way of recycling then it passes through the parallax barrier layer onto the TFT-LCD. If it meets the barrier area then it reflects again. If there is no loss of light on the way of propagating the optical components of reflective polarizer, active retarder and BLU, then all lights emitting from BLU go to TFT-LCD through the slit area.The light efficiency of it exceeded at least two times that of conventional one.
