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

As described above, phase inversion controller 37 of liquid crystal display device 10a of the second modification inverts the phase of the polarity of the data voltage in units of m (m is an integer of 1 or more) pixel rows, and shifts position of pixel row 22 where the phase of the polarity of the data voltage is inverted by a predetermined pixel row for every predetermined frames.

Consequently, even if the frame inversion drive is the drive in which the polarity of the data voltage is inverted every frame, and even if m (number of N lines) is an even number, the data having the same polarity can be prevented from being supplied to the pixel row, so that the generation of the image quality degradation can further be prevented.

Second Exemplary Embodiment

A liquid crystal display device according to a second exemplary embodiment will be described below with reference to FIGS. 9 to 13.

[2-1. Configuration of Liquid Crystal Display Device]

A schematic configuration of liquid crystal display device 10b of the second exemplary embodiment will be described below with reference to FIG. 9. FIG. 9 is a block diagram illustrating a functional configuration of liquid crystal display device 10b of the second exemplary embodiment.
