Patent ID: 8687133

Claim:
A display device comprising: a display panel for alternately generating first visible images and second visible images; a backlight module for generating two different polarized backlights to alternately illuminate the display panel so as to output the first visible images and second visible images respectively, wherein the backlight module comprises: a single light source; a first polarizing beam splitter for splitting light beams from the single light source into two different groups of polarized outgoing light beams; a first reflector and a second reflector for reflecting the polarized light beams from the first polarizing beam splitter; a first switch shutter disposed between the first reflector and the first polarizing beam splitter; a second switch shutter disposed between the second reflector and the first polarizing beam splitter; and a second beam splitter for directing the light beams from the first reflector or second reflector to the display panel; and a synchronization module being coupled with the first switch shutter, the second switch shutter and the display panel for synchronizing the first visible images and second visible images with illumination periods of the respective polarized backlights.
