Abstract: A touch device includes a touch sensing unit, a processing unit, an embedded controller and a digital controller. The touch sensing unit has a first control mode and a second control mode, and senses a touch event from a touch stylus. The embedded controller is coupled to the processing unit. The digital controller is coupled to the touch sensing unit, the embedded controller and the processing unit, and receives a general-purpose input/output (GPIO) signal from the embedded controller. When the GPIO signal is in a first value, the digital controller reports the first control mode to the processing unit. When the GPIO signal is in a second value, the digital processor reports the second control mode to the processing unit. Thus, the performance of the touch device and the touch stylus is improved.

Abstract: An electronic device includes a first electronic component and a second electronic component. The first electronic component includes a control unit and a first connector. A first pin group of the first connector includes an even number of first detect pins. The second electronic component includes a second connector that matches with the first connector. A second pin group of the second connector includes an even number of second detect pins. When the first connector is electrically connected to the second connector, each of the first detect pins is electrically connected to each of the second detect pins to form a conductive path. All of the first detection pins and the second detection pins connected with one another in series form the conductive path. And a first end of the conductive path is coupled to ground via one of the first detect pins. A second end of the conductive path is coupled to the control unit via another one of the first detect pins.

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.
