A first output unit outputs a control signal for removing a residual electric charge from a liquid crystal display module that includes a backlight. A reference-signal obtaining unit obtains a reference signal for setting a reference when turning on the backlight. A delay-time setting unit sets a delay time for delaying a turn-on time of the backlight from a turn-on time of the reference signal. A second output unit outputs a turn-on signal for turning on the backlight at a turn-on time delayed by the delay time from the turn-on time of the reference signal.
