Device and method for driving display panel

A non-transitory storage medium having a computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to generate display image data for driving a display panel based on original image data representing a display image comprising an effective area to be displayed in a display area of the display panel and an invalid area not to be displayed in the display area, wherein the display image data comprises:

• effective pixel data associated with first pixels in the effective area;
• and
• invalid pixel data associated with second pixels in the invalid area,
• wherein generating the display image data comprises setting the effective pixel data associated with one or more of the first pixels to first grayscale values, the one or more of the first pixels located within a boundary area adjacent to the invalid area, and
• wherein the invalid pixel data associated with one or more the second pixels is set to second grayscale values, the one or more of the second pixels located within an insert area defined in the invalid area and the second grayscale values comprise a value different from the first grayscale values.

A method, comprising:

• generating display image data for driving a display panel based on an original image data representing a display image comprising an effective area to be displayed in a display area of the display panel and an invalid area not to be displayed in the display area,
• wherein the display image data comprises:
• effective pixel data associated with first pixels in the effective area;
• and
• invalid pixel data associated with second pixels in the invalid area, wherein generating the display image data comprises:
• setting the effective pixel data associated with one or more of the first pixels to first grayscale values, the at least some of the first pixels located within a boundary area adjacent to the invalid area, and
• setting the invalid pixel data associated with one or more of the second pixels to second grayscale values, the one or more of the second pixels located within an insert area defined in the invalid area, and
• wherein the second grayscale values comprises a value different from the first grayscale values.
