Method for driving display including curved display area, display driving circuit supporting the same, and electronic device including the same

An electronic device comprising:

• a display;
• a processor operatively connected to the display and configured to generate display data to be output via the display;
• a display driver integrated circuit configured to output, via the display, the display data which the processor transfers,
• wherein the display driver integrated circuit is configured to:
• output a screen including an image displaying area, a blank area partially surrounding the image displaying area, and a boundary area disposed between the image displaying area and the blank area,
• apply a color transformation value of the same or different magnitude to at least some pixels of the boundary area of a display data depending on a distance from a specified point of the display to a location where the display data are to be displayed.

A method for driving a display, the method comprising:

• outputting a screen including an image displaying area, a blank area partially surrounding the image displaying area, and a boundary area disposed between the image displaying area and the blank area,
• obtaining a value of a location of the boundary area, at which display data are to be output;
• calculating a distance between the location value and a specified point of the display;
• calculating a color transformation value to be applied to the display data depending on the calculated distance;
• applying the calculated color transformation value to at least some pixels of the boundary area of;
• and
• outputting the display data, to which the color transformation value is applied, on the display.

A display driver integrated circuit comprising:

• a receive interface configured to receive display data from a processor;
• a memory configured to store the display data;
• a mask processing unit, comprising circuitry, configured to obtain information about a location of a display area, at which the display data stored in the memory are to be output, to calculate a color transformation value to be applied to the display data depending on a distance between a specified point and the location, and to output the display data, to which the color transformation value is applied;
• and
• a display timing controller configured to output the display data on a display.
