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

Phase inversion controller 37 prevents the horizontal steak from being visually recognized, so that the number of pixel rows (N lines) constituting the pixel row group that is a collection of the pixel rows to which the data voltage having the same polarity is supplied can be increased. In other words, the number of inversion positions I where the polarity of the data voltage is inverted can be decreased. Consequently, the effect that reduces the power consumption is obtained.

Thus, liquid crystal display device 10c can reduce the power consumed in the liquid crystal panel while preventing the generation of the image quality degradation.

As described above, the display method of liquid crystal display device 10c of the third exemplary embodiment is a display method of liquid crystal display device 10c configured by arranging the plurality of pixels P in a matrix form, the phase of the polarity of the data voltage is inverted in units of m (m is an integer of 1 or more) pixel rows, and the position of the pixel row (for example, inversion position I) where the phase of the polarity of the data voltage is inverted is shifted by each predetermined pixel row for each frame.

Other Exemplary Embodiments

The liquid crystal display device and the display method of the liquid crystal display device of the present disclosure are described above based on the exemplary embodiments, but the present disclosure is not limited to the exemplary embodiments.
