Abstract:
1. A switchable stereoscopic display system, wherein the switchable stereoscopic display system can display three-dimensional images, comprising: an organic light emitting diode (OLED) display device including a two-dimensional array of light emitting elements; a first electronic means for rapidly updating individual OLEDs; means for linearly polarizing light emitted from the two-dimensional array of light emitting elements in the OLED display device; a circular polarizing layer capable of changing light from linearly polarized light to circular polarized light; a polarization layer, on top of the circular polarization layer, and capable of switching a polarization direction of emitted light from a right-handedness to a left-handedness or alternatively switch polarization direction from a left-handedness to a right-handedness; a second electronic means for causing the switching of polarization direction within independent segments of the polarization layer, during a first time period, wherein the emitted light from a first subset of the independent segments is provided either left-handedness polarization or right-handedness polarization and the emitted light from a second subset of the independent segments is provided an opposite polarization from the polarization of the first subset of independent segments, and during a second time period, polarization handedness of the first and second subset of independent segments reverses; and temporal synchronization means for synching refreshed OLEDs with the independent segments of the polarization layer such that individual OLEDs are switched synchronously with the polarization handedness of the independent segments allowing each individual OLED to provide high-resolution of image information and to reduce flickering of the image information, for a display user.
