An electronic device with a switchable display screen, a computer system of the electronic device and a method therefor are provided. The electronic device includes a processing unit, a DisplayPort interface, a keyboard control unit, a switch module, and a display panel module. The processing unit generates a first display data according to a DisplayPort standard. When the DisplayPort interface is coupled to an external device, the DisplayPort interface receives an external display data transmitted by the external device. The keyboard control unit generates a switch signal according to a switch event. The switch module selects the first display data or the external display data to be a screen data according to the switch signal. The display panel module coupled to the switch module receives and displays the screen data on a display panel. Thus, the external device may share display content with the display panel of the electronic device. |

1. An electronic device comprising:
a processing unit generating a first display data according to a digital display standard; a digital display interface, wherein when the digital display interface is coupled to an external device, the digital display interface receives an external display data transmitted by the external device; a keyboard control unit generating a switch signal according to a switch event; a switch module coupled to the processing unit, the digital display interface, and the keyboard control unit, the switch module selecting the first display data or the external display data to be a screen data according to the switch signal, wherein the switch module comprises:
a first switch, wherein a first connection end of the first switch is coupled to the display panel module, a second connection end of the first switch is coupled to the processing unit to receive the first display data, and a control end of the first switch is coupled to the keyboard control unit to receive the switch signal; anda second switch, wherein a first connection end of the second switch is coupled to the digital display interface, a second connection end of the second switch is coupled to a third connection end of the first switch, a third connection end of the second switch is coupled to the processing unit, and a control end of the second switch is coupled to the keyboard control unit to receive the switch signal,wherein when the switch signal is disabled, the second switch switches on the first and second connection ends of the second switch to transmit the external display data to the third connection end of the first switch, the first switch switches off the first and second connection ends of the first switch and switches on the first and third connection ends of the first switch to effect the external display data as the screen data and transmit the screen data to the display panel module; and a display panel module coupled to the switch module, the display panel module receiving and displaying the screen data on a display panel. |
