Image display device and display method for image display device
摘要
說明書
The data voltage is not supplied to the non-writing line determined not to have the correlation in the frame. Consequently, the numbers of drive times of source driver 24 and gate driver 25 in one frame can be decreased, leading to the further reduction of the power consumption.
Thus, liquid crystal display device 10 can further reduce the power consumed in the liquid crystal panel while further preventing the generation of the image quality degradation.
Controller 30 controls source driver 24 so as to perform the column inversion drive in which the polarities of the data voltage supplied to two adjacent data signal lines SL are different from each other. The plurality of writing lines (an example of the first pixel row) exist in one frame. Controller 30 determines whether the correlation in the image exists between the writing line (for example, writing line 22a2) located in the center in the column direction in three writing lines arranged side by side and each of at least two non-writing lines (an example of the second pixel row, for example, non-writing lines 22b21 to 22b25 and 22b31 to 22b35) disposed between the writing line and the rest two writing lines (for example, writing lines 22a1 and 22a3).
