A method for motion blur in an LED display system includes the steps of connecting an LED display panel to a driver circuit; sending, from a transmitter, image data in a plurality of image frames at a predetermined frame rate and a predetermined refresh rate to the driver circuit, wherein each of the plurality of image frames has a frame time period (T) comprising a plurality of refresh time periods (T); outputting a driving current in the driver circuit to drive the LED display; and turning off the driving current for a period of time (T). Tbridges two adjacent frame time periods. The value of Tcan be determined according to a viewer of persistence of vision or by calibrating the LED display.
