Claim:
1. A display device for achieving synchronized interaction with a terminal device, including: a receiving module configured to receive an image frame from a terminal device; a first decoder configured to decode the image frame to obtain decoded image data and transmit the decoded image data to a display module; the display module configured to perform an outputting and displaying process on the decoded image data; a touch module configured to generate a first coordinate data to achieve a touch and display function, in response to an image display command corresponding to a touch point of a user on a touch screen; a touch point coordinate extracting module configured to read the first coordinate data of the touch point of the user on the touch screen; a microcontroller configured to convert the first coordinate data into a second coordinate data according to a correspondence between a resolution of the display device and a resolution of the terminal device; an encoder configured to generate a control frame including the second coordinate data; and a transmitting module configured to transmit the control frame to the terminal device; wherein the control frame includes a communication protocol identifier for identifying a communication protocol, a terminal device identifier ID and a data segment storing the second coordinate data.
