Abstract:
This disclosure provides a circuit and a method for driving an LED display. The driving circuit comprises a selection circuit for selecting a first light emitter from the plurality of light emitters, a pre-charging circuit for charging an equivalent capacitor of the display panel with respect to the selected first light emitter, and a power circuit for supplying power to the first light emitter after the first light emitter is selected, wherein the power circuit is configured to supply a driving current to the first light emitter in one or more stages. The driving circuit and method of this disclosure can be used to significantly increase the refresh rate and resolution of the LED display.
