Abstract:
1. A system for driving a display, the system comprising: an array of pixel circuits that includes a plurality of subsections arranged in a grid, each of said pixel circuits comprising a light emitting device and a driving transistor for conveying a driving current through the light emitting device; a first plurality of pairs of supply lines providing driving currents to said pixel circuits, at least one of each of said pairs of supply lines being coupled to all the pixel circuits in one of said subsections; multiple adjustable voltage supplies configured to provide an adjustable supply voltage to at least each of said supply lines that are coupled to all the pixel circuits in one of said subsections; a controller for determining, based on digital data indicative of an amount of luminance to be emitted from the pixel circuits in each of said subsections, an output level sufficient to enable the pixel circuits in each of said subsections to emit light according to the digital data.
