Abstract

A backplane operative to drive an array of emissive pixel elements is disclosed. Each pixel element comprises a memory cell operative to modulate a plurality of current mirror drive elements configured to drive one emissive element, wherein a plurality of current mirror pixel drive elements may be individually enabled by external control signals. The width W of the reference current FET of a first selectable current mirror circuit will differ from the width W of the reference current FET of a second selectable current mirror circuit. The ratio of the width W of the current source FET to the width W of the reference current FET in a first selectable current mirror pixel drive element is equal to the ratio of the width W of the current source FET to the width W of the reference current FET in a second selectable current mirror pixel drive element.
