Abstract
A 3D LED display panel that includes a substrate and an array light emitting devices mounted on the substrate. The array of light emitting devices includes a plurality of first light emitting devices and a plurality of second light emitting devices. Each first light emitting device has an LED chip/package electrically connected to the substrate and a piece of first circular polarizer attached to the LED chip/package. Likewise, each second light emitting device includes an LED chip/package electrically connected to the substrate and a piece of second circular polarizer attached to the LED chip/package. The first circular polarizer the second circular polarizer have opposite circular polarizations.
