Abstract
A multi-color inorganic light-emitting diode (iLED) display includes a display substrate with a common voltage signal and a common ground signal and a plurality of multi-color pixels. In certain embodiments, each multi-color pixel includes a first color sub-pixel including two or more first iLEDs, a second color sub-pixel including one or more second iLEDs, and a third color sub-pixel including one or more third iLEDs. The two or more first iLEDs are serially connected between the common voltage signal and the common ground signal, the one or more second iLEDs are serially connected between the common voltage signal and the common ground signal, and the one or more third iLEDs are serially connected between the common voltage signal and the common ground signal.
