Optical device and display operating in two dimensional and autostereoscopic three dimensional modes |
摘要 |
An optical device comprises an input polarizer 4, a patterned retarder 5 and an output polarizer 12. The retarder 5 has regions 8 and 9, at least one of which alters the polarization of light from the input polarizer 4. The output polarizer 7 has a transmission axis 12 such that light passing through the regions 8 and 9 of the retarder 5 and through the output polarizer 7 is matched in amplitude, phase and polarization. Such a device may be used as a switchable parallax barrier with an LCD 2 to provide a display which is switchable between an autostereoscopic 3D mode and a 2D mode with the 2D mode having more uniform intensity across the display.
