1. A display comprising:
a first pixel formed from a first anode, a cathode, and organic light-emitting diode layers, wherein the first anode comprises a first portion in a first layer and a second portion in a second layer, wherein the second portion is electrically connected to the first portion and has a first thickness, wherein the first pixel has an optical cavity defined by a first distance between the first portion and the cathode, and wherein the first pixel includes first and second dielectric layers that are interposed between the first portion of the first anode and the second portion of the first anode; and
a second pixel formed from a second anode, the cathode, and the organic light-emitting diode layers, wherein the second anode comprises a third portion and a fourth portion, wherein the fourth portion is electrically connected to the third portion and has a second thickness that is different than the first thickness, wherein the second pixel has an optical cavity defined by a second distance between the third portion and the cathode, and wherein the second distance is different than the first distance.
