In a power supply apparatus for performing constant current driving of a light emitting diode which is a load circuit, a constant current circuit is disposed on a path for driving the load circuit. A charge pump circuit which is a voltage generating circuit outputs a driving voltage to the light emitting diode. A monitoring circuit monitors the voltage across the two ends of the constant current circuit. This monitoring circuit includes a voltage source which generates a threshold voltage that follows the fluctuation of the voltage at which the constant current circuit can operate stably, compares the voltage across the two ends of the constant current circuit and the threshold voltage generated by the voltage source, and outputs a comparison result Vs to a control unit. The control unit controls the charge pump circuit on the basis of the output of the monitoring circuit.

A drive control circuit sends out pulse signals of various pulse signals so as to control the light emission amount and luminance of LEDs by gradually increasing and decreasing the pulse width in predetermined cycles during predetermined periods based on parameters supplied from an LED drive controller that determine a first emission control processing period, a second emission control processing period, first to fourth slope periods and the like. The tone of an emitted color realized by a plurality of LEDs is controlled by synchronizing the periods of time of light emission control processings.

An LCD panel module includes a common boosting converter, an LCD boosting circuit, an LDO control circuit, and constant current circuits for parallel-connected LED elements and series-connected LED elements. The LCD panel module is so configured that a type-switching unit can switch over between Type 1 in which the LED elements are connected in parallel and Type 2 in which the LED elements are connected in series. The common boosting converter preliminarily boosts a battery voltage supplied from a lithium ion battery to a low voltage or a high voltage and supplies the boosted voltage to the parallel-connected LED elements or series-connected LED elements respectively. The LCD boosting circuit boosts the low voltage and supplies it to an LCD panel, while the LDO control circuit steps down the high voltage and supplies it to the LCD panel.
