3D stereoscopic display system for large format LED displays

A method for displaying a 3D image from a wall comprising a plurality of light emitting diodes (LEDs), said method comprising:

• a) polarizing a first subset of said LEDs with a first sheet of polarizing material 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;
• b) polarizing said second subset of said LEDs with a second sheet of polarizing material to form a second view of said 3D image, said second sheet comprising a plurality of polarizing material 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 second sheet is layered together with said first sheet;
• c) diffusing luminance of light emanated from said LEDs rear diffuser, the rear diffuser disposed between said display and said first sheet of polarizing material to reduce the concentration of light from a small to a large area of the polarizing material, so as to increase the efficiency of the polarizing material and to reduce the ghosting artifacts that interfere with the 3D effect;
• d) reducing glare from light emanated from light sources external from said display with a front diffuser, the front diffuser disposed in front of said second sheet of polarizing material;
• e) increasing the viewing angle of the display with the front diffuser by projecting a polarized image of an illuminated pixel onto the front surface on the front diffuser so as to be visible by a view at a wide angle;
• f) using the combination of the front and rear diffusers to create a larger size illumination area, as compared to the LED pixels alone, to decrease the pixilation effects of the display and to create a smoother image in 2D or 3D modes of use;
• and
• g) using 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.

An apparatus comprising:

• a) a display comprising a plurality of light emitting diodes (LEDs) for displaying 3D image content;
• b) a plurality of first button polarizers for polarizing a first subset of said LEDs to form a first view of said 3D image, at least one of said plurality of first button polarizers substantially aligned with at least one of said first subset of said LEDs;
• c) plurality of second button polarizers for polarizing a second subset of said LEDs to form a second view of said 3D image, at least one of the plurality of second button polarizers substantially aligned with at least one of said second subset of said LEDs, wherein said second button polarizers are layered upon said first button polarizers;
• d) at least one of said plurality of first button polarizers comprises a frosted surface;
• e) at least one of said plurality of first button polarizers comprise a left-facing key and wherein at least one of said plurality of second button polarizers comprises a right-facing key;
• and
• f) at least one of said plurality of first button polarizers comprises polarizing material for polarizing light in a first polarizing direction;
• and wherein at least one of said plurality of second button polarizers comprise polarizing material for polarizing light in a second polarizing direction.
