Data display method and device
First Claim
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.

Abstract
A low power display and a method for display in a display device having an Active Matrix Organic Light Emitting Diodes AMOLED panel are provided. A display window that includes content to be displayed on the AMOLED panel is determined. Luminance values of pixels constituting the display window are grasped. The pixels having luminance values that are to be adjusted are determined in accordance with a distribution degree of pixels having luminance values that are larger than a reference luminance value. The luminance values of the determined pixels are changed to the reference luminance value, and the display window is displayed on the AMOLED panel with the changed luminance values.

7. A display device comprising:
-
an Active Matrix Organic Light Emitting Diodes (AMOLED) panel; and a control unit configured to determine a display window including content to be displayed on the AMOLED panel, to determine a luminance value of each pixel included in the display window, to determine a representative luminance value of each pixel included in the display window from among luminance values of respective neighboring pixels, to compare 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 the 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, to identify the at least one pixel as a pixel having a luminance value that is to be adjusted, and to adjust the luminance value of the identified at least one pixel to the reference luminance value, and to display the display widow with the identified at least one pixel having the adjusted luminance value on the AMOLED panel. - View Dependent Claims (8, 9, 10, 11, 12, 13)
