Stereoscopic display apparatus employing light emitting diodes with polarizing film/lens materials
A stereoscopic display system including an array of Light Emitting Diodes (LEDs) is provided. The system includes a plurality of left LEDs, each left LED comprising a left housing, a left light transmitter arrangement within the left housing, and a left polarizing element positioned with the left housing above the left light transmitter arrangement and a plurality of right LEDs, each right LED comprising a right housing, a right light transmitter arrangement within the right housing, and a right polarizing element positioned with the right housing and above the right light transmitter arrangement. At least one left housing and left polarizing element pair are each irregularly formed and fit together, and at least one right housing and right polarizing element are each irregularly formed in a manner complementary to the at least one left housing and left polarizing element.
1. A stereoscopic display system, comprising:
an array of (a) multiple left polarizing Light Emitting Diode housings (left LED housings), and (b) multiple right polarizing Light Emitting Diode housings (right LED housings), wherein:
each of the multiple left LED housings is individually addressable, and each is a unitary material body which includes a cavity within which is disposed a light emitting element and a left polarizing element;
wherein within each cavity of the multiple left LED housings (1) the left polarizing element is bonded to the light emitting element, and (2) a wall of the housing is disposed lateral to the polarizing element; and
each of the multiple right LED housings is individually addressable, and each is a unitary material body which includes a cavity within which is disposed a light emitting element and a right polarizing element;
wherein within each cavity of the multiple right LED housings (1) the right polarizing element is bonded to the light emitting element, and (2) a wall of the housing is disposed lateral to the polarizing element;
wherein each of the multiple left LED housings are configured to receive a first viewing channel, and each of the multiple right LED housings are configured to receive a second viewing channel, different from the first viewing channel; and
wherein the multiple left LED housings are different from the multiple right LED housings as a function of their different left and right polarizing elements.
2. The stereoscopic display system of claim 1 , wherein at least one left LED housing contains a left diffuser element.
3. The stereoscopic display system of claim 1 , wherein the plurality of left LED housings are linearly arranged in a plurality of rows.
4. The stereoscopic display system of claim 1 , wherein the plurality of left LED housings and the plurality of right LED housings are arranged in a checkerboard pattern.
5. The stereoscopic display system of claim 1 , wherein the left polarizing element of at least one of the left LED housings has an abraded surface that faces the corresponding light emitting element.
6. The stereoscopic display system of claim 5 , wherein at least one of the left polarizing housings has a visually distinguishable feature selected from the group consisting of a key mark, a slot, and a cut-out.
7. The stereoscopic display system of claim 1 , wherein each of the multiple left LED housings transmits circularly polarized light in a first directionality, and each of the multiple right LED housings transmits circularly polarized light in a second directionality different from the first directionality.
8. The stereoscopic display system of claim 1 , wherein each of the multiple left LED Housings transmits linearly polarized light in a first directionality, and each of the multiple right LED housings transmits linearly polarized light in a second directionality.
9. The stereoscopic display system of claim 1 , wherein the LEDs of each of the multiple left LED housings is configured to addressably emit multiple colors.
