Patent ID: 8564627

Claim:
An image display device comprising: a display panel including a plurality of gate lines for scanning which extend in a horizontal direction, a plurality of source lines which extend in a vertical direction to intersect the plurality of gate lines, the source lines being supplied with drive signals based on input image signals, and a plurality of sub-pixel electrodes arranged one by one in positions corresponding to intersections of the plurality of gate lines and the plurality of source lines, each of the sub-pixel electrodes being independently controlled for driving; and a drive control section performing a drive control of the display panel by selectively using two drive modes of a first drive mode and a second drive mode, to display an image based on the input image signal on the display panel, the first drive mode allowing horizontal lines of the plurality of sub-pixel electrodes to be scanned one line at a time through sequentially selecting the plurality of gate lines one by one, and the second drive mode allowing the horizontal lines of the plurality of sub-pixel electrodes to be scanned N lines at a time through sequentially selecting the plurality of gate lines N lines at a time, where N is an integer of 2 or more, wherein the display panel is configured in such a manner that a first sub-pixel electrode and a second sub-pixel electrode are alternately arranged in the horizontal direction and in the vertical direction, in the first drive mode, the drive control section performs display drive in such a manner that the first and second sub-pixel electrodes, arranged adjacent to each other in the horizontal direction along a gate line and arranged on two respective source lines, are driven based on two respective gray scale values different from each other, and that a combination of the first and second sub-pixel electrodes is treated as a single pixel, and in the second drive mode, the drive control section performs display drive in such a manner that the horizontal lines of the plurality of sub-pixel electrodes are scanned two lines at a time through sequentially selecting the plurality of gate lines two lines at a time, and that the first and second sub-pixel electrodes, both arranged adjacent to each other in the vertical direction along a source line and arranged along two respective gate lines, are treated as a single pixel.
