Abstract
A multi-color LED display comprises pixels, each comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel comprises a first light-emitting diode (LED) that emits a first color of light, the second sub-pixel comprises second LEDs that emit a second color of light different from the first color of light, and the third sub-pixel comprises third LEDs that emit a third color of light different from the first color of light and different from the second color of light. The second LEDs are electrically connected in parallel and the third LEDs are electrically connected in series.
