Abstract
A 3D display apparatus includes a display device, a liquid crystal panel, and a lens unit. The display device is configured to output polarized lights of one or more images with a first polarization direction. The liquid crystal panel is coupled to the display device and contains a plurality of pixel display areas to receive the polarized lights. The display areas can be individually controlled by corresponding active switches to a first state in which the first polarization direction is transformed into a second polarization direction or a second state in which the first polarization direction is maintained. Further, the lens unit is coupled to the liquid crystal panel and is configured to guide the polarized lights with the second polarization direction to pass through for 2D display and to guide polarized lights with the first polarization direction into predetermined transmitting directions for 3D display.
