Method and system for determining overdrive pixel values in display panel

A system for determining an overdrive mapping correlation in a display panel, comprising:

• a display having a plurality of subpixels;
• and
• a processor, comprising:
• a graphics pipeline configured to generate a plurality of pixel values for the plurality of subpixels in each frame,
• a pre-processing module configured to:
• determine a repeating subpixel arrangement that comprises at least three sets of subpixels in the display panel;
• determine an ideal luminance value of a pattern of the subpixel arrangement by determining an actual luminance value of another pattern of the subpixel arrangement, the pattern comprising at least a first set of subpixels displaying a zero pixel value, a second set of subpixels displaying a first nonzero pixel value, and a third set of subpixels displaying a second nonzero pixel value, the first, second, and third sets of subpixels respectively arranged one after another, the first nonzero pixel value being different from the second nonzero pixel value, and the other pattern comprising the second set of subpixels displaying the first nonzero pixel value and the rest of the plurality of subpixels displaying the zero pixel values,
• determine an actual luminance value of the pattern of the subpixel arrangement, and
• determine an overdrive pixel value from the first nonzero pixel value to the second nonzero pixel value by matching the actual luminance value of the pattern to the ideal luminance value of the pattern;
• a luminance measuring unit configured to measure the actual luminance value of the pattern of the subpixel arrangement and transmit the actual luminance value of the pattern to the pre-processing module;
• and
• a data transmitter configured to transmit the plurality of pixel values from the processor to the display in the frame.

A non-transitory computer-readable medium that stores a set of instructions, when executed by at least one processor, cause the at least one processor to determine a method for determining an overdrive mapping correlation in a display panel, the method comprising:

• determining a repeating subpixel arrangement that comprises at least three sets of subpixels in the display panel;
• determining an ideal luminance value of a pattern of the subpixel arrangement by determining an actual luminance value of another pattern of the subpixel arrangement, the pattern comprising at least a first set of subpixels displaying a zero pixel value, a second set of subpixels displaying a first nonzero pixel value, and a third set of subpixels displaying a second nonzero pixel value, the first, second, and third sets of subpixels respectively arranged one after another, the first nonzero pixel value being different from the second nonzero pixel value, and the other pattern comprising the second set of subpixels displaying the first nonzero pixel value and the rest of the plurality of subpixels displaying the zero pixel values;
• determining an actual luminance value of the pattern of the subpixel arrangement;
• and
• determining an overdrive pixel value from the first nonzero pixel value to the second nonzero pixel value by matching the actual luminance value of the pattern to the ideal luminance value of the pattern.
