Abstract
An active matrix display includes a display element for producing a visual output when the display element is driven with a constant current, and drive circuitry for controllably driving a substantially constant current through the display element. The drive circuitry includes a two-transistor inverter having an inverter input and a common node output, and the common node output of the inverter is connected, directly or indirectly, to supply or control the current passing through the corresponding display element.
