AI Technical Summary
In multi-screen different display scenarios, the main screen usually has only one HDMI interface and one TYPEC interface, and it is impossible to send different video signals to multiple secondary screens through two interfaces at the same time. In the prior art, it is compatible with HDMI and TYPEC by setting a conversion chip or using different PCBAs, which is relatively expensive.
A circuit compatible with HDMI and TYPEC is designed, including an HDMI interface, a TYPEC interface, a MCU and a switch module. The MCU controls the on-off of the switch module by detecting the insertion of the signal source, and realizes the signal input of the HDMI and TYPEC interfaces.
On the basis of not using an external converter, the signal input of the HDMI and TYPEC interface is realized through pin switching, which reduces the cost and meets the needs of multi-screen different display scenarios.

[0026] As described in the background art, in a multi-screen heterogeneous display scenario, there is a main screen and multiple secondary screens. The main screen needs to output different video signals to the secondary screens respectively so that the multiple secondary screens can display content.
[0027] Since there is usually only one HDMI interface (High-Definition Multimedia Interface) and one TYPE-C interface (a type of USB interface) on the main screen, in this case, the main screen can only send one video signal to one secondary screen through one of the HDMI interface or the TYPE-C interface, and send another video signal to another secondary screen through the other of the HDMI interface or the TYPE-C interface.
[0028] However, since the two secondary screens are only respectively connected to one of the HDMI interface or the TYPE-C interface on the main screen through one of the HDMI interface or the TYPE-C interface, it is necessary to be compatible with HDMI and TYPE-C. In the related art, it is usually achieved by setting a conversion chip, or by separately making different PCBAs for the HDMI interface and the TYPE-C interface, generating two sets of BOMs to be compatible with HDMI and TYPE-C, resulting in a relatively high cost.

Through the present disclosure, signal input compatible with the HDMI interface and the TYPE-C interface is achieved by switching pins without using an external converter.
