摘要： A display method for driving a color-sequential display of an electronic device is provided. When the electronic device is not at low power mode, a first image is displayed first by using a second color data and a first color data of the first image sequentially to drive the display. Next, a second image is displayed by using a second color data and a third color data of the second image sequentially to drive the display. When the electronic device is at low power mode, the respective luminance of the first and the second images are obtained. Then, the respective luminance of the first image and the second image are sequentially used to drive the display.

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.
