Controller 30 controls gate driver 25 and source driver 24 such that respective data voltage is written in every predetermined pixel rows 22 among the plurality of pixel rows 22 in one frame among the plurality of frames. The first pixel row is the pixel row (writing line) in which the data voltage is written. The second pixel row is the pixel row (non-writing line) in which the data voltage is not written when controller 30 determines that the first pixel row does not have the correlation in one frame.
Consequently, the power consumption of the liquid crystal panel can be further reduced due to the existence of the non-writing lines in one frame. When the non-writing line has the correlation with the writing line in the image, the data voltage corresponding to the writing line is supplied to the non-writing line. Consequently, the frame frequency is increased in the non-writing line, so that the generation of the image quality deterioration due to the charge loss can be prevented. The data voltage corresponding to the correlation line in the frame after the data voltage of the writing line, which is the data voltage similar to the data voltage corresponding to the correlation line, is written in the correlation line. Consequently, the generation of the image quality degradation due to the decrease in frame frequency of the pixel row can be prevented.
When the data voltage of the writing line is supplied to the non-writing line, the data transfer is not performed from controller 30 to source driver 24. That is, source driver 24 consumes little power when the data voltage of the writing line is supplied to the non-writing line. In other words, the number of pixel rows in which the data voltage is written can be increased without increasing the power consumed by source driver 24.
