1. A control circuit of a blind-mating display having two Type-C interfaces, comprising:
a display control module,
a first Type-C interface module,
a second Type-C interface module,
a first switching switch module,
a second switching switch module, and
a dielectric module;
wherein the dielectric module is electrically connected to the first Type-C interface module and the second Type-C interface module; the display control module is electrically connected to the dielectric module;
wherein the first switching switch module is electrically connected to the first Type-C interface module and the second Type-C interface module; the display control module is electrically connected to the first switching switch module;
wherein the second switching switch module is electrically connected to the first Type-C interface module and the second Type-C interface module; the display control module is electrically connected to the second switching switch module; the display control module is connected to a display terminal;
when both of the first Type-C interface module and the second Type-C interface module are inserted into devices, and the devices are respectively a source device and a power delivery (PD) device; the dielectric module is configured to transmit a source device insertion signal and a PD device insertion signal to the display control module;
the first switching switch module is configured to switch the display control module to connect to configuration channel (CC) communication lines of the first Type-C interface module or CC communication lines of the second Type-C interface module, so as to realize time-sharing communication between the display control module and the source device or time-sharing communication between the display control module and the PD device; or
wherein the display control module is configured to control CC communication lines of the first switching switch module to connect to the first Type-C interface module or the second Type-C interface module inserted into the source device; and the display control module is configured to connect the dielectric module to the second Type-C interface module or the first Type-C interface module inserted into the PD device, so charging gear information of the PD device is sent to the source device;
wherein the display control module is configured to control the CC communication lines of the first switching switch module to connect to the first Type-C interface module or the second Type-C interface module inserted into the PD device, and the display control module is configured to switch the second switching switch module to connect to the second Type-C interface module or the first Type-C interface module inserted into the source device, so a charging gear request of the source device is sent to the PD device;
wherein the display control module is configured to control the PD device to communicate with a power supply of the source device; the display control module is configured to realize rapid charging control of the PD device to the source device.
