Abstract
Methods, apparatuses, and systems to control current through a sub-pixel micro-LED (mLED) of a mLED display using a dynamic current mirror are taught. A dynamic current mirror is shifted to phase zero. Phase zero includes establishing a first voltage for a sub-pixel mLED control transistor. The first voltage is produced using a predetermined reference current. An energy storage device used in the sub-pixel mLED is charged to the first voltage during phase zero. The dynamic current mirror is shifted to phase one. In phase one, the first voltage is used with the sub-pixel mLED control transistor to pass an illumination current through the sub-pixel mLED.
