Abstract

Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a transparent anode structure that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. The reflective anode structure may be formed from a silver alloy having a high reflectance. The transparent anode structure may be electrically connected to the reflective anode structure using a via or may be formed in direct contact with the reflective anode structure. The reflective anode structures may be formed using chemical mechanical polishing of a silver alloy.
