1. A display device, comprising:
a controller circuit;
an image transmission interface circuit connected to an electronic device through an image transmission interface to receive image data transmitted by the electronic device, in order to display the image data through the controller circuit, wherein the image transmission interface is a high-definition multimedia interface (HDMI), and the image transmission interface circuit transmits the first command to the electronic device through a display data channel of the high-definition multimedia interface; and
an input/output interface circuit connected to a control device to receive a first command from the control device,
wherein the control device transmits the first command to the electronic device through the image transmission interface, in order to operate as a human interface device connected to the electronic device, such that the electronic device operates in response to the first command; and
wherein the electronic device is configured to issue a read command to the first slave address through an inter-integrated circuit (I2C) protocol, and the control device is configured to transmit the first command to the electronic device through the image transmission interface in response to the read command, in order to operate as the human interface device connected to the electronic device.
