OLED voltage driver with current-voltage compensation

Abstract:

A mobile electronic device includes a display having an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The mobile electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry drives the pixel based at least in part on a degraded current-voltage relationship of the pixel, a reference current-voltage relationship of the reference pixel, and an aged current-voltage relationship.
