Abstract: Light emitting diode (LED) packages and LED displays utilizing the LED packages are disclosed. LED packages can have a plurality of cavities with each having one or more LEDs. The LEDs can be individually controllable so that the LED package emits the desired color combination of light from the package. The LED packages are arranged with an encapsulant over the cavities that shape the LED package emission to a wide angle or pitch. Some of the LED packages can have three cavities, while others can have four or more cavities. The packages can comprise an encapsulant that forms lenses over the cavities and continues beyond the cavities to cover surfaces of the LED package body. The body can include different anchoring features to improve package reliability by anchoring the encapsulant to the body. One embodiment of an LED display according to the present invention comprises a plurality of LED packages, at least some having a plurality of cavities.

Abstract: 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.

Abstract: The present invention is directed to LED packages and LED displays utilizing LED packages where the peak emission of the LED displays can exhibit improved emission characteristics. In some embodiments the improved characteristics include a wider horizontal emission angle for the LED packages according to the present invention, which results in improved emission characteristics for the LED display such as a wider far field pattern. This provides improved picture intensity and quality when viewing the display at different horizontal viewing angles. Different embodiments also provide for improved emission characteristics for LED packages emitting different colors of light when viewing at different vertical angles. In one embodiment the red and green LED packages can have emission patterns that are substantially the same at different vertical viewing angles within a range. This helps the colors of the display appear consistent at those angles.
