1. A multi-color LED display, comprising:
pixels, each of the pixels comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel, the first sub-pixel comprising first light-emitting diodes (LEDs) that emit a first color of light, the second sub-pixel comprising second LEDs that emit a second color of light different from the first color of light, and the third sub-pixel comprising third LEDs that emit a third color of light different from the first color of light and different from the second color of light,
wherein at least two of the first LEDs are electrically connected in parallel, more than two of the second LEDs are electrically connected in parallel, and more than two of the third LEDs are electrically connected in series,
and wherein the second sub-pixel comprises more second LEDs than first LEDs in the first sub-pixel and the third sub-pixel comprises more third LEDs than first LEDs in the first sub-pixel.
