Abstract: Pixel circuits 6 have a rectangular shape longer in an extending direction of scanning signal lines than in an extending direction of data signal lines. Three pixel circuits 6 arranged in the extending direction of data signal lines form one pixel. A pixel having three pixel circuits 6 arranged in the order red, green, and blue, a pixel having three pixel circuits 6 arranged in the order green, blue, and red, and a pixel having three pixel circuits 6 arranged in the order blue, red, and green are repeatedly arranged in the extending direction of scanning signal lines. By this, when line inversion drive is performed using a data signal line drive circuit 4, voltages of different polarities are applied to three types of pixel circuits 6 in each line in each frame to cancel out the influence of the polarities of the applied voltages, thereby suppressing a color shift.

Abstract: A fixing unit 8 is fitted with a rail 28 along which a rail guide provided inside an image forming apparatus can slide. This allows the fixing unit 8 to be extracted out of the image forming apparatus. When the fixing unit 8 is extracted out of the image forming apparatus, a transferring body separating member 26, which has thus far been prevented from rotating by the rail 28, is made to rotate by the force applied by a tension spring 27. An end portion of the transferring body separating member 26 presses a transfer roller bracket 24 and thereby moves a transfer roller 17. Thus, the transfer roller 17 is separated from a photoconductor drum 2.

Abstract: An object of the present invention is to provide (i) a display device which, during a display of a moving image and a still image, reduces electric power consumption without causing a deterioration in display quality, and (ii) a method for displaying the display device. In an intermittent drive mode in which driving and a pause of the driving are repeated, an image identification section (6) identifies an input image (image data (DA)) as a still image or a moving image. In a case where the input image is identified as the moving image, a drive/pause control section (7) generates a drive/pause control signal (DSC) in accordance with a period ratio which is in accordance with the moving image. A timing control section (8) generates a driver control signal so that intermittent driving is carried out. Then, a source driver (3) and a gate driver (4) drives a display section (2) so that the drive period and the pause period are repeated in accordance with a predetermined period ratio, so that the input image (DA) is displayed. The drive/pause control section (7) sets a time ratio between the drive period and the pause period so that the time ratio is variable for each of the moving image and the still image.

Abstract: In a driving method for driving a liquid crystal display device, each of frame periods is divided into a drive period in which a counter electrode is driven, and a drive suspension period in which the counter electrode is not driven. During the drive period, a data signal is outputted to a video signal line driving circuit at a frequency corresponding to a driving frequency for driving the counter electrode. During the drive suspension period, the outputting of the data signal is stopped. Thus, there are provided a liquid crystal display device and a driving method therefor, in which user aggravating sound is prevented without increasing power consumption.
