The invention relates to a display control device and a display panel module. Power consumption in interlace driving of a display panel is reduced. A halt period is inserted between a drive period inan odd-numbered field and a drive period in an even-numbered field in interlace driving. When drive signals driving subpixels are time-divisionally supplied to the display panel in units of subpixel types, switch control signals controlling source line switches which distribute the drive signals associated with respective subpixels to the corresponding source lines are generated so that the numberof switching of the source line switches are reduced.
