Abstract
An active matrix OLED flat-panel display includes a plurality of light emitting elements and associated control circuits; a programmable power supply connected to the control circuits; a sensor for sensing the light output of one or more light emitting elements to produce a feedback signal; and a display controller responsive to the feedback signal for programming the programmable power supply to compensate for changes in the light output from the light emitting elements.
