Patent ID: 7408201

Claim:
A system comprising: a first light emitting diode that is non-lasing and having an epitaxial structure comprising an active region sandwiched between an n-type region and a p-type region, the active region configured to emit light that is at least 50% polarized along a first polarization orientation when forward biased wherein percent polarization is defined as:  I p - I s  I p + I s × 100 ⁢ % where I p and I s are the intensities of vertically and horizontally polarized light; a microdisplay disposed in a path of light emitted by the active region from the first light emitting device; a second light emitting diode that is non-lasing and having an epitaxial structure comprising an active region sandwiched between an n-type region and a p-type region, the active region of the second light emitting diode configured to emit light that is at least 50% polarized along a second polarization orientation when forward biased; a polarizing beamsplitter disposed in the path of the light having a first polarization orientation emitted by the first light emitting diode and light having a second polarization orientation emitted by the second light emitting diode, wherein the polarizing beamsplitter combines the light having a first polarization orientation and the light having a second polarization orientation; and wherein the microdisplay receives the light having a first polarization orientation and the light having a second polarization orientation after being combined by the polarizing beamsplitter.
