Abstract
A stereoscopic display module includes an array of multiple light emitting packages, each of which is topped by a polarizer. Package-polarizer sets are closely spaced, such that at 10% of oblique light from a middle package-polarizer set is blocked by adjacent package-polarizer sets. In preferred embodiments 0.3h≤d≤0.7h, where h is the distance between the bottom of the polarizers and the bottom of the light emitters, and d, the distance between edges of adjacent light-emitting packages. Glass-On-Board (GOB) packages and Chip-On-Board (COB) packages are contemplated, with any suitable combination of color light emitters. Modules preferably include arrays of at least 9, 16, 32, 64, and 128 package-polarizer sets.
Claims23
A stereoscopic display module, comprising:
- a substrate;
- at least first, second, and third light emitting packages physically coupled to the substrate, wherein the second package is situated between the first and third packages;
- and
- each of the first, second, and third packages includes one or more light emitter(s) collectively configured to emit at least three different visible colors of light;
- wherein first, second, and third polarizers are disposed above light emitters of the first, second and third packages to form first, second, and third, package-polarizer sets, respectively;
- and
- wherein the first, second and third package-polarizer sets are sufficiently closely spaced that the first and third package-polarizer sets block at least 10% (the blocked percentage) of visible light collectively emitted by the light emitter(s) in the second package, which would otherwise pass out of the display module without passing through the second polarizer.
A stereoscopic display module, comprising:
- a substrate;
- at least first, second and third light emitting packages physically coupled to the substrate, wherein the second package is situated between the first and third packages;
- and
- each of the first, second, and third packages includes one or more light emitter(s) collectively configured to emit at least three different visible colors of light;
- wherein the first, second, and third polarizers are disposed above light emitters of the first, second and third packages to form first, second, and third, package-polarizer sets, respectively;
- and
- wherein the first package-polarizer set has a height h between a bottom of the polarizer and a bottom of a first one of the light emitters, and there a distance d between the first and second package-polarizer sets such that 0.3h≤d≤0.7h, inclusive.
