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

Details of step S140 will be described below with reference to FIGS. 12 and 13. FIG. 12 is a flowchart illustrating the operation of liquid crystal display device 10b of the second exemplary embodiment. FIG. 13 is a view illustrating the comparison of the correlation in liquid crystal display device 10b of the second exemplary embodiment. FIG. 13 illustrates the case where controller 30b controls source driver 24 by the column inversion drive. FIG. 13 illustrates two hatched dots, and illustrates an example in which pixel row 22 having the high-density hatched dot is the reference line while pixel row 22 having the low-density hatched dot is the correlation line.
