Device and method for setting display driver

A non-transitory tangible storage medium storing a program when executed causes a processor to perform a method comprising:

• obtaining brightness values of a pixel-existing area and a pixel-absent area of a display panel;
• generate updated brightness values by replacing at least one of the brightness values of the pixel-absent area with a suitable value;
• generating mura correction data based on the updated brightness values;
• and
• configuring a display driver with the mura correction data for updating the display panel.

A display driver setting apparatus, comprising:

• a processor configured to:
• obtain brightness values of a pixel-existing area and a pixel-absent area of a display panel;
• generate updated brightness values by replacing at least one of the brightness values of the pixel-absent area with a suitable value;
• generate mura correction data based on the updated brightness values;
• and
• generate compressed mura correction data by compressing the mura correction data;
• and
• an interface configured to supply the compressed mura correction data to a display driver configured to drive the display panel.

A display driver, comprising:

• a non-volatile memory configured to store compressed mura correction data;
• decompression circuitry configured to generate decompressed mura correction data by decompressing the compressed mura correction data;
• image processing circuitry configured to correct an image data based on the decompressed mura correction data;
• and
• driver circuitry configured to drive a display panel based on the corrected image data.
