1. A light emitting diode (LED) display module, comprising:
a plurality of red, green, blue, cyan, amber (RGBCA) light emitting diode (LED) packages spaced apart from each other in an array of between 100×100 and 250×250 and mounted on a single printed circuit board; and
electronics adapted to operate the plurality of RGBCA LED packages,
wherein each RGBCA LED package is a pixel that is addressable individually by the electronics, each RGBCA LED package including a red LED chip, a blue LED chip, a green LED chip, a cyan LED chip and an amber LED chip,
wherein the red LED chip, the blue LED chip and the green LED chip operate at a narrow bandwidth, and the cyan LED chip and amber LED chip operate at a wide bandwidth, the cyan LED chip bandwidth being between the blue LED chip bandwidth and the green LED chip bandwidth, and the amber LED chip bandwidth being between the red LED chip bandwidth and the green LED chip bandwidth.
