With the development of games and virtual reality, data interfaces of VR devices (for example, the external interface of the display card described in the above embodiments) are developed towards a Type-C interface with a miniaturization feature, but because the Type-C interface for outputting data of the display card is generally disposed on a rear panel of a VR host, the VR device is not easy to plug and unplug when being used, and a cable for accessing the Type-C interface is long. Based on this, if design the external Type-C interface that is used for exporting display card data in the VR equipment to the leading panel of VR host computer, all have fine help to user's use and performance promotion. For example, a DP data bus is directly led out from the output end of the graphics card to be connected to the data interface of the front panel of the VR host. However, in this way, a Type-C interface needs to be additionally added on the front panel of the VR host to specifically support output of graphics card data, and the graphics card data can be displayed on an external device (i.e., the second electronic device) accessing the Type-C interface.
Based on this, in the embodiment of the present application, as shown in fig. 7, two types of Type-C output interfaces, namely, an internal Type-C interface 711 and an external Type-C interface 712, are designed on the graphics card 71, and the external Type-C interface 712 is also designed on the rear data interface of the VR host 70, and the internal Type-C interface 711 may be directly connected to a DP cable line, so as to be connected to the front Type-C interface 721 having multiple functions (Full function) on the VR host 70, so that the front Type-C interface 721 of the VR host supports output and display of DP data (i.e., the first data) of the graphics card 71 without affecting other multiple functions of the front Type-C interface 721. Therefore, a data interface is not required to be additionally arranged on the front panel of the VR host 70 to specially support the output and display of DP data, so that the wiring is simple, and the cost is reduced. In addition, because the front Type-C interface 721 of the VR host 70 supports the output and display of DP data of the graphics card 71, when using the VR headset (i.e. the second electronic device), the user does not need to move the VR host 70 to find the rear Type-C interface 712, but can directly access the VR headset to the front Type-C interface 721 for use; in addition, the VR host 70 has strong practicability because the preset Type-C interface 721 adds the DP function of automatically borrowing back to the graphics card without affecting the situation that the preset Type-C interface 721 supports the functions of Universal Serial Bus (USB) 3.0, DP, PD, and the like.
It should be noted that, as shown in fig. 7, when the Type-C interface 721 on the system motherboard 72 is designed, a high-speed signal switching module 724 (i.e., the signal switching module) needs to be added in the middle of the output of the CPU 722 to the MUX IC723, where the high-speed signal switching module 724 is mainly used to switch the DP signal (i.e., the first data) of the built-in Type-C interface 711 on the graphics card 71 and the DP signal or USB data (i.e., the second data) that the CPU 722 sends to the MUX IC723 to output to the Type-C interface 721;
as shown in fig. 7, the connection of the built-in Type-C interface 711 of the graphics card 71 to the DP input terminal of the high-speed signal switching module 724 (i.e., the fourth transmission channel) may be implemented by a DP cable.
When the system motherboard 72 has the display card 71 plugged therein, that is, the display card 71 is plugged into the system motherboard 72 through the PCIE interface and the built-in Type-C interface 711, the CPU 722 detects and sends a GPIO (general purpose input output) signal (that is, a first connection signal having the first signal value), so as to trigger the high-speed signal switching module 724 and gate the built-in Type-C interface 711 of the display card 71 to a transmission channel (that is, the first transmission channel) of the Type-C interface 721 on the system motherboard 72.
Through the VR host 70 shown in fig. 7, it can be realized that the Type-C interface 721 supports the display function of the display card on the premise that the functions of USB, DP, PD, etc. of the Type-C interface 721 of the VR host 70 are not affected, so that the user experience of the VR host is greatly improved.
