PIXEL CORRECTION PROCESSING METHOD, CORRECTION PROCESSING CIRCUIT, AND DISPLAY DEVICE INCLUDING CORRECTION PROCESSING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a pixel correction processing technology that suppresses a disclination even if a thinning-out drive or skipping drive is implemented.;SOLUTION: A pixel correction processing method in a drive method of writing with respect to a plurality of scan lines comprises: a gradation value calculation process that calculates a deemed gradation value of at least one pixel of two pixels adjacent in a vertical direction; a boundary detection process that detects a risk boundary in which a gradation value of a low gradation side pixel is equal to or more than a first gradation value, and a gradation value of a high gradation side pixel is equal to or more than a second gradation value greater than the first gradation value, and a value obtained by subtracting the gradation value of the low gradation side pixel from the gradation value of the high gradation side pixel is equal to or more than a prescribed threshold; and a correction process that corrects at least one of gradation values of the two pixels on the basis of the gradation values of two pixels including the pixel of the calculated deemed gradation value so that a difference between the gradation values of the two pixels is small.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
