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

A schematic configuration of liquid crystal display device 10 of the first exemplary embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram illustrating a functional configuration of liquid crystal display device 10 of the first exemplary embodiment. FIG. 2 is a view illustrating a schematic configuration of liquid crystal panel 20 in liquid crystal display device 10 of the first exemplary embodiment.

As illustrated in FIG. 1, liquid crystal display device 10 includes liquid crystal panel 20 and controller 30. Liquid crystal display device 10 includes components such as a backlight (not illustrated). Liquid crystal display device 10 is an example of the image display device. Liquid crystal panel 20 is an example of the display panel included in the image display device.

Liquid crystal panel 20 displays an image (for example, a color image) visually recognized by a user based on a control signal from controller 30. A liquid crystal drive system of liquid crystal panel 20 may be an IPS (In Plane Switching) system, a VA (Vertical Alignment) system, or other drive systems. For example, liquid crystal panel 20 is normally black, displays white during voltage application, and displays black during no voltage application. However, liquid crystal panel 20 may be normally white.

Source driver 24 and gate driver 25 are provided in liquid crystal panel 20 in order to display an image corresponding to an input video signal on image display region 21.
