Patent ID: 11017701

Abstract:
A correction data generating device is a device 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, and includes a display controller supplying each of the plurality of pixels with display signal voltages corresponding to two or more grayscale levels; an acquisition portion 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 specification portion 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 acquired by the acquisition portion; and a generation portion generating correction data based on the at least one abnormal pixel and the at least one correction target grayscale level specified by the specification portion.
