“…Because of the success of <Avatar>, many researchers were interested in developing 3D display technology to pursue more natural perceived quality, especially autostereoscopic 3-D displays that do not need wear 3-D glasses [1] . On the other hand, most information still be displayed in the form of 2-D, so we really need a technology that can be switchable between 2-D and 3-D.In virtue of the advantage such as no luminance loss, LC lens are more suited to 2-D/3-D display than LC parallax barrier, especially GRIN LC lens which with simple structure and manufacture process matching with LCD.…”
