摘要

An image display device includes: a display; gate signal lines including a first pixel row and a second pixel row; a gate driver; data signal lines; a source driver; and a controller that determines whether the second pixel row has correlation with the first pixel row in an image. When determining that the second pixel row has the correlation with the first pixel row, the controller causes the source driver to supply the data voltage corresponding to the first pixel row, causes the gate driver to supply the gate signal to write the data voltage in the first pixel row, and causes the gate driver to supply the gate signal to write the data voltage corresponding to the first pixel row in the second pixel row.

說明書

Subsequently, the correlation is sequentially determined in the column direction. Determination unit 32 determines whether the line (pixel row 22) immediately below the head line has the correlation with the reference line (S144). In the second exemplary embodiment, the line immediately below the head line is the reference line (pixel row 2) selected in step S110. When the negative determination is made in step S141, for example, when the reference line is located at a scanning position of the initial reference line (the reference line selected in step S110, pixel row 2 in the part (a) of FIG. 13) of the frame, the correlation is not determined, but the initial reference line (pixel row 2) is set to the reference line again, and whether the reference line set again has the correlation with the subsequent lines is sequentially determined. In this case, for example, in step S144, whether the line (pixel row 3) immediately below the reference line set again has the correlation with the reference line set again is determined.
