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

Thus, the components described in the attached drawings and the detailed description include not only the components necessary for the solution of the problem but also the components not necessary for the solution of the problem in order to exemplify the technique. For this reason, it should not be immediately recognized that the unnecessary components are necessary as those unnecessary components are described in the accompanying drawings and detailed description.

For example, the low-power driving such as the thinning-out drive is performed in the liquid crystal display device of the exemplary embodiment. Alternatively, the low-power drive and normal drive may be switched. In the normal drive, the supply of the gate signal to the plurality of gate signal lines is completed from top to bottom by the source driver and the gate driver (that is, the plurality of gate signal lines are scanned in the arrangement order), thereby writing the data voltage corresponding to the image data in all the pixels once. In the normal drive, the image of one frame is generated by writing the image data for all the pixels.

In the embodiments, by way of example, the liquid crystal display device includes the liquid crystal panel as the display panel. However, the present disclosure is not limited to the embodiments. For example, the present disclosure can be applied to an image display device including an organic EL panel as the display panel.

In the embodiments, by way of example, the liquid crystal display device includes one liquid crystal panel. However, the present disclosure is not limited to the embodiments. The liquid crystal display device may be a display device in which a plurality of liquid crystal panels are superimposed on each other to display one image using the plurality of liquid crystal panels.
