Abstract:
1. An apparatus comprising: a) a display comprising a plurality of light emitting diodes (LEDs) for displaying 3D image content; b) a first sheet of polarizing material for polarizing a first subset of said LEDs to form a first view of said 3D image, said first sheet comprising a plurality of openings substantially aligned with a second subset of said LEDs; c) a second sheet of polarizing material for polarizing said second subset of said LEDs to form a second view of said 3D image, said second sheet comprising a plurality of openings substantially aligned with said first subset of said LEDs, wherein said first sheet and second sheet are layered together; d) a rear diffuser disposed between said display and said first sheet of polarizing material, for diffusing luminance of light emanated from said LEDs to reduce the concentration of light from a small to a larger area of the polarizing material, so as to increase the efficiency of the polarizing material to reduce the ghosting artifacts that interfere with the 3D effect; e) a front diffuser, disposed in front of said second sheet of polarizing material, for reducing glare from the light emanated from light sources external from said display and for increasing the viewing angle of the display by projecting a polarized image of an illuminated pixel onto the front surface on the front diffuser so as to be visible by a viewer at a wide angle; and f) eyewear for viewing said 3D image, said eyewear comprising a left and a right lens that polarizes light complementary to said first and second sheets of polarizing material to create a left eye view and a right eye view from said first and second views.
