Zusammenfassung:Light emitting diode (LED) packages and LED displays utilizing the LED packages are disclosed. LED packages can have a cavity with emitters arranged in close proximity to approximate a point light source, with each of the packages emitting a color combination of light from the emitters. The LED packages are arranged with an encapsulant or lens over the cavity that shapes the LED package emission to a wide angle or pitch. One embodiment of an LED package according to the present invention comprises a cavity with a plurality LEDs. The LED package also comprises a lens over the cavity to shape the emission of the LEDs to a wider angle along an axis compared to emission of the LEDs without the lens. The LEDs are individually controllable, with the LED package emitting different color combinations of emission from the LEDs. One embodiment of an LED display according to the present invention comprises a plurality of LED packages, at least some having a cavity with a plurality of LEDs. Each of the packages comprises a lens over each cavity to produce an emission of the LEDs that has a wider angle compared to the emission without the lens. The LED packages are mounted within the display to generate a wide angle image.
