Pixel design and method to create formats which extends OLED life

A display system includes an organic light emitting diode (OLED) display and a controller. The display includes an array of pixels, each pixel comprising a first group of subpixels and a second group of subpixels. The first group of subpixels includes single subpixels of different colors. The second group of subpixels includes one or more subgroups of subpixels, where each subgroup includes a plurality of subpixels of the same color. The controller is configured to provide a voltage to the first group of subpixels and to at least one of the subpixels of each subgroup of subpixels according to a first data format. The controller is configured to provide a voltage to at least another of the subpixels of each subgroup of subpixels, and not to the first group of subpixels, according to the second data format.
