Method and device for determining compensation grayscale value of display panel, and display device

A device for determining a compensation grayscale value of a display panel, comprising:

• a first searching device configured to search, in a table of grayscale bit number judgment values, for a grayscale bit number judgment value corresponding to a sub-pixel to be compensated;
• and
• a compensation grayscale value determining device configured to determine a compensation grayscale value corresponding to the sub-pixel to be compensated by a first reading process if the grayscale bit number judgment value satisfies a grayscale bit number condition, and to determine the compensation grayscale value corresponding to the sub-pixel to be compensated by a second reading process if the grayscale bit number judgment value does not satisfy the grayscale bit number condition,
• wherein the first reading process comprises:
• searching, in a table of first compensation grayscale values, for a first grayscale value position corresponding to the sub-pixel to be compensated, and determining the compensation grayscale value corresponding to the sub-pixel to be compensated in accordance with data at the first grayscale value position, and
• wherein the second reading process comprises:
• searching, in the table of first compensation grayscale values, for the first grayscale value position corresponding to the sub-pixel to be compensated;
• searching, in a table of second compensation grayscale values, for a second grayscale value position corresponding to the sub-pixel to be compensated;
• and determining the compensation grayscale value corresponding to the sub-pixel to be compensated in accordance with the data at the first grayscale value position and data at the second grayscale value position.
