Abstract

An organic light-emitting diode (OLED) display device is provided having a color emission layer including a plurality of organic light-emitting elements in a first arrangement and an electronics layer. The electronics layer includes a plurality of pixel drive circuits each including an electrode contact. The electronics layer includes a plurality of independently addressable sub-regions each sub-region including an identical pattern of electrode contacts created using a single reticle exposure. Each sub-region is orientated differently within a plane such that the first arrangement of light-emitting elements is electrically connected to the patterned electronics layer.
