Abstract: A switching control circuit is included in a boost direct current to direct current (DC-DC) converter generating an analog power supply voltage to be supplied to a source driver. The switching control circuit supplies a switching pulse to a control terminal of a switching element varying an inductor current such that an operation mode transitions to a current continuation mode during a first predetermined period that is at least a portion of a time duration that continues from a moment when the operation mode transitions from the current continuation mode to a current discontinuation mode in response to transitioning from an efficient video period to a vertical blanking period to a moment when the vertical blanking period transitions to the effective video period.
