Correction data generating device, computer program, method for generating correction data, and method for producing display panel

A computer program causing a computer to generate correction data for correcting input grayscale level vs. luminance characteristics of a plurality of pixels included in a display region of a display panel, the computer program causing the computer to execute:

• a process of supplying each of the plurality of pixels with display signal voltages corresponding to two or more grayscale levels;
• a process of acquiring two or more luminances of each of the plurality of pixels supplied with the display signal voltages respectively corresponding to the two or more grayscale levels;
• a process of specifying, among the plurality of pixels, at least one abnormal pixel, the input grayscale level vs. luminance characteristic of which needs to be corrected and also specifying at least one correction target grayscale level including a grayscale level that needs to be corrected, based on the two or more luminances of each of the plurality of pixels;
• and
• a process of generating correction data based on the at least one abnormal pixel and the at least one correction target grayscale level.

A correction data generating method for generating correction data for correcting input grayscale level vs. luminance characteristics of a plurality of pixels included in a display region of a display panel, the correction data generating method comprising:

• step (a) of supplying each of the plurality of pixels with display signal voltages corresponding to two or more grayscale levels;
• step (b) of acquiring two or more luminances of each of the plurality of pixels supplied with the display signal voltages respectively corresponding to the two or more grayscale levels;
• step (c) of specifying, among the plurality of pixels, at least one abnormal pixel, the input grayscale level vs. luminance characteristic of which needs to be corrected and also specifying at least one correction target grayscale level including a grayscale level that needs to be corrected, based on the two or more luminances, acquired in the step (b), of each of the plurality of pixels;
• and
• step (d) of generating correction data based on the at least one abnormal pixel and the at least one correction target grayscale level specified in the step (c).
