| 摘要 |
A light-emitting diode device that includes a first group of sub-pixels each subpixel comprising a reflective electrode and a second electrode formed over a substrate with an unpatterned light-emitting layer formed between the reflective electrode and the second electrode, thus forming a first optical cavity having a first cavity length. Either the reflective or second electrode is patterned to form two or more independently-controllable, light-emitting sub-pixels. A second group of sub-pixels, each comprising a reflective electrode and a second electrode formed over the substrate. An unpatterned light-emitting layer is formed between the reflective electrode and the second electrode to comprise a second optical cavity having a second cavity length different from the first cavity length of the first optical cavity. Either the reflective or second electrode is patterned to form one or more independently-controllable, light-emitting sub-pixels.
