1. A low power display method in a display device having an Active Matrix Organic Light Emitting Diodes (AMOLED) panel, the method comprising the steps of:

  • determining a display window including content to be displayed on the AMOLED panel;

    determining a luminance value of each pixel included in the display window;

    determining a representative luminance value of each pixel included in the display window from among luminance values of respective neighboring pixels;

    comparing both the luminance value of each pixel included in the display window and the representative luminance value of each pixel included in the display window with a reference luminance value;

    when both a luminance value of at least one pixel included in the display window and a representative luminance value corresponding to the at least one pixel are larger than the reference luminance value, identifying the at least one pixel as a pixel having a luminance value to be adjusted;

    adjusting the luminance value of the identified at least one pixel to the reference luminance value; and

    displaying the display window with the identified at least one pixel having the adjusted luminance value.
