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.

As described above, the plurality of writing lines exist in one frame, and determination unit 32 determines whether the writing line (for example, writing line 22a2) located at the center in the column direction among three writing lines (for example, writing lines 22a1 to 22a3) arranged side by side has the correlation with each of at least two non-writing lines (for example, pixel row 22 constituting non-writing line groups 22b2 and 22b3 disposed between the writing line and the rest two writing lines (for example, writing lines 22a1 and 22a3) except for the writing line. Determination unit 32 determines whether each of the non-writing lines (for example, pixel rows 22 constituting non-writing line groups 22b2 and 22b3) located up to writing lines 22a1 and 22a3 vertically located in the column direction with respect to writing line 22a2 has the correlation with writing line 22a2.

As illustrated in FIG. 4, for example, non-writing line group 22b2 is located in both ranges R1 and R2. That is, whether each of non-writing lines 22b21 to 22b25 constituting non-writing line group 22b2 has the correlation with each of writing lines 22a1 and 22a2 is determined. An example in which the determination that non-writing line 22b23 constituting non-writing line group 22b2 has the correlation with both writing lines 22a1 and 22a2 is made will be described below.
