The embodiments of the present disclosure provide a method for displaying an image on a dual-screen display panel. According to an embodiment, the dual-screen display panel comprises a dimming screen and a display screen. The method comprises: generating first image data for the dimming screen according to image data; determining dimming driving voltages for a plurality of dimming areas based on the first image data according to a grayscale-dimming driving voltage relationship; determining display driving voltages for a plurality of display areas based on the image data according to a grayscale-display driving voltage relationship; and driving the dimming screen and the display screen with the determined dimming driving voltages and display driving voltages, respectively, to display the image.
