Abstract
In first and second display devices (10, 20) both during pause drive (intermittent drive), an instantaneous increase in consumption power is suppressed by means of a configuration to perform control such that the scanning period in one of the two display panels is inserted during the scanning-stopped period in the other display panel, namely during the drive operation (for writing into the pixel circuit) of one of the two display panels, the drive operation (for writing) of the other display panel is not performed. Accordingly, even when a limit value of a current supply capability of a battery is low, the display device can be driven, so that a battery service life is prolonged and the operable time of a portable terminal (100) at the time of driving by the battery is increased.
