Abstract: A detecting circuit of an external display device includes a first connector, a display circuit configured to provide a display signal to the external display device through the first connector, a switch circuit, a power supply circuit configured to provide power needed for operating the display circuit through the switch circuit when the switch circuit is on, and a control circuit configured to turn on the switch circuit upon detecting the external display device so as to connect the power supply circuit to the display circuit. When the switch circuit is on, the control circuit accumulates a duration or a number of times of detection that the external display device is continually not detected, and then turns off the switch circuit to disconnect the power circuit from the display circuit when the duration reaches a time threshold or the number of times of detection reaches a count threshold.

Abstract: An electronic device includes a communication module, an external module and a signal integration circuit. The signal integration circuit includes a first input port, a second input port, a third input port and an output port. The first input port is for inputting an input signal. The second input port is for selectively inputting a first L1 band signal. The third input port is for selectively inputting a second L1 band signal. The output port selectively outputs a first output signal or a second output signal. When the third input port is coupled to an external module, the third input port is for inputting the second L1 band signal, and the output port outputs the second output signal. When the third input port is not coupled to the external module, the second input port is for inputting the first L1 band signal, and the output port outputs the first output signal.
