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

For example, memory controller 38 writes the image data and the determination result output from determination unit 32 in memory 40, and outputs the image data and the determination result read from memory 40 to determination unit 32.

Memory 40 has a storage capacity storing the image data used to determine the correlation in determination unit 32. Memory 40 has a storage capacity capable of storing the image data for at least one frame.

[2-2. Operation of Liquid Crystal Display Device]

The operation of liquid crystal display device 10b will be described below with reference to FIGS. 10 to 13. FIG. 10 is a flowchart illustrating the operation of liquid crystal display device 10b of the second exemplary embodiment. FIG. 11 is a view illustrating the case where the correlation is not compared in liquid crystal display device 10b of the second exemplary embodiment.
