A display device includes a display component coupled to a signal generating unit with a single trace. The signal generating unit generates a first signal. A processing unit, connected to the display component and the single trace, receives the first signal through the single trace and generates a first type control signal, a second type control signal, and a third type control signal according to the first signal. The processing unit generates and controls an on-screen display menu displayed by the display component according to status of the display device and the received first signal as one of the first type control signal, the second type control signal, and the third type control signal.

Method for controlling display

The invention provides a boost circuit including a first capacitor, a transformer, a sensing resistor and a second capacitor. The transformer has a boost side coil with its one end connected in series with the first capacitor. The sensing resistor is connected in series with the other end of the boost side coil of the transformer, and one end of the second capacitor is connected in parallel with the transformer. Also, the invention provides a power supply converter including a boost circuit and a detection circuit. The boost circuit is used to produce a voltage and output a detection signal to detect the occurrence of a spark. The detection circuit is electrically connected with the boost circuit and is used to receive the detection signal output by the boost circuit. When the detection circuit detects the detection signal contains an inrush signal, it determines that a spark is occurring within the boost circuit and outputs a control signal according to the inrush signal.
