A display comprising: an array of pixel units, each comprising a light emitting diode (LED) programmable between a first state in which it emits light when forward biased above its turn-on voltage and a second state in which it does not emit light when forward biased above its turn-on voltage; an addressing unit by which the pixel units are addressed; and a controller operable to control the addressing unit to apply, in a first phase, drive voltages across the LEDs which program their state, and in a second phase, drive voltages across the LEDs above their turn-on voltages. |
