    摘要: The present invention discloses a method for driving a light emitting diode according to a required luminance, wherein an actual luminance of the light emitting diode decays with time and a correlation there between is represented by a life-time curve. The method comprises the following steps. First, the driving current is correlated with the required luminance by an initial coefficient is provided to the light emitting diode. Next, a length of a period of use of the light emitting diode is counted. Then, a slope of the life-time curve corresponding to the required luminance is stored. Finally, a new coefficient from the length of the period of use, the slope of the life-time curve and the initial coefficient is derived.
