Abstract
A lighting system includes an LED array having a plurality of LED pixels and a power controller. The power controller adjusts a supply voltage for powering the LED pixels based on one or more conditions of the LED array. The power controller may determine the supply voltage based on process data of the LED array. The power controller may adjust the supply voltage based on an operating temperature of the LED pixels and the amplitude of a current driving the LED pixels.
