  • Relating to drivers
    Patent number: 10311785
    Abstract: A driver circuit for an LED display for switching a light-emitting diode (LED) between a non-luminous state and a luminous state for producing light for a display, the driver circuit comprising an LED, a drive current controller (10) arranged to selectively open and close a drive current flow path (8) through the LED (2) thereby selectively to switch the LED between a non-luminous state and a luminous state, a charge injector unit (13) for inputting charge into the LED to store said charge within the LED via the junction capacitance (3) thereof, a control unit (12) arranged to control the charge injector unit to input said charge into the LED concurrently with the opening of the drive current flow path.
    Type: Grant
