Abstract
In one example, a method includes outputting, by a power supply and across a supply node and a ground node, a supply power signal; and selectively outputting, by a driver, a power signal to a second terminal of a light emitting element that has a first terminal and the second terminal, wherein the first terminal of the light emitting element is coupled to a load node, wherein a supply terminal of the driver is coupled to the supply node, wherein a ground terminal driver is coupled to the ground node, and wherein a difference between a potential of the supply node and a potential of the ground node is less than an activation voltage of the light emitting element.
