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

In the exemplary embodiment, by way of example, the determination unit makes the correlation determination using the image data in which the predetermined image processing is performed on the input image signal. However, the present disclosure is not limited to the exemplary embodiment. For example, the determination unit may determine the correlation based on the input image signal before the predetermined image processing is performed.

In the exemplary embodiment, by way of example, the controller controls the source driver by the column inversion drive or the row line inversion drive to display the image. However, the driving method is not limited to the exemplary embodiment. The controller may display the image by controlling the source driver by the dot inversion drive in which the polarity of the data voltage between adjacent pixels is inverted while performing the frame inversion drive in the thinning-out drive, or the controller may control the source driver by another driving method to display the image.
