1. A display apparatus, comprising:
a display;
a communicator, configured to receive information input from a terminal device; and
a controller, in connection with the display and communicator and configured to:
while the display apparatus is in communication connection with the terminal device, in response to change of device information of the display apparatus, send network information of the display apparatus to the terminal device, so that the terminal device generates a request for obtaining device information according to the network information, wherein the request for obtaining device information is configured to obtain changed device information of the display apparatus; and
in response to the request for obtaining device information sent from the terminal device, send the changed device information to the terminal device, and re-establish a communication connection with the terminal device;
wherein the controller is further configured to:
receive a communication connection request sent from the terminal device through a network;
in response to the communication connection request, send the network information of the display apparatus to the terminal device;
receive a first obtaining request sent from the terminal device, wherein the first obtaining request is configured to obtain the device information of the display apparatus; and
send the device information of the display apparatus to the terminal device, and establish the communication connection with the terminal device;
in response to the communication connection request, send a physical address of the display apparatus to the terminal device, so that the terminal device generates the first obtaining request according to the network information and the physical address;
while the display apparatus is in the communication connection with the terminal device, in response to change of the physical address and the network information of the display apparatus, send changed network information and a changed physical address to the terminal device, so that the terminal device generates a second obtaining request according to the changed network information and the changed physical address, wherein the second obtaining request is configured to obtain current device information of the display apparatus; and
in response to the second obtaining request sent from the terminal device, send the current device information of the display apparatus to the terminal device, and re-establish the communication connection with the terminal device.
