摘要： A polarity of a POL outputted from a polarity inversion control section (9) is always identical between a scanning period and a pause period immediately subsequent to the scanning period, and is reversed every time switching from a pause period to a scanning period is carried out. This makes it possible to both carry out pause driving and prevent image sticking on a display panel.

摘要： A polarity inversion control section (9) supplies a polarity designation signal, which designates a polarity of a data signal, to a data line drive circuit (5) while reversing a polarity of the polarity designation signal every frame. Even in a case where a pause driving control section (8) receives a designation signal that designates a sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an even number, the pause driving control section (8) maintains the sum of the number of frames constituting a scanning period and the number of frames constituting a pause period to be an odd number.

摘要： A method for driving a display device capable of appropriately performing idle driving even when timing information is not transmitted to a liquid crystal module in advance is provided. In a case where, in one vertical period, a non-scanning period other than a scanning period in which a screen of a display unit is scanned once is set to a pause period, a liquid crystal module delays supply of a data signal to the display unit by a recovery period during which a source driver is recovered from a sleep state to an active state in the pause period.

摘要： An object of the present invention is to further reduce the power consumption of a display device adopting pause driving. In a display device that includes a display driving unit (30) that drives a display unit (400); and a power supply circuit (20) that generates a plurality of operation voltages to be supplied to the display driving unit (30), and performs pause driving that repeats a scanning period during which gate bus lines (GL) are scanned and a pause period during which the scanning of the gate bus lines (GL) is stopped, the display driving unit (30) provides a control signal (SM) indicating whether the current point in time is the scanning period or the pause period, to the power supply circuit (20), and the power supply circuit (20) makes the voltage value of at least one of the plurality of operation voltages supplied to the display driving unit (30) smaller during the pause period than during the scanning period, based on the control signal (SM).

摘要： A timing controller carries out display refresh on a display panel in a first frame which comes one frame after a second frame in which (i) an image signal supplied from an interface matches an image signal stored in a frame memory and (ii) a polarity balance value is equal to a reference value. In this case, the image signal, having a polarity opposite to that of pixel applied voltages in the second frame, is supplied to the display panel in the first frame. This makes it possible to prevent a deterioration in the display panel while reducing electric power consumption.

摘要： A liquid crystal display device is provided where deterioration of the liquid crystal panel is prevented while reducing power consumption. A liquid crystal panel (12) includes a display region (26) in which a video is displayed. The display region (26) includes a plurality of sub-regions (26A, 26B, 26C, 26D). A drive unit (14) rewrites the display on at least one of the plurality of sub-regions (26A, 26B, 26C, 26D) based on a video signal. An identification unit (38) identifies the one of the plurality of sub-regions (26A, 26B, 26C, 26D) on which the drive unit (14) has not rewritten the display for a predetermined number of frames. An output unit (40) outputs an interrupt signal for requesting a video signal for rewriting the display on the sub-region identified by the identification unit.
