Data transmission structure

A data transmission structure, comprising:

• a system including a receiving unit, at least a transmission module and a host coupled with the receiving unit and the transmission module;
• and
• a visual interface display apparatus including a receiving module and a display module including a display panel, wherein the display panel includes a display matrix, the display matrix includes a plurality of row electrodes and a plurality of column electrodes, a display signal for displaying image is transmitted to a row electrode and a column electrode in a display area of the display panel so as to display image by the display panel,
• wherein when the receiving module receives a transmission data transmitted by the transmission module, a response data is generated according to the transmission data and is transmitted to at least one of the plurality of row electrodes and the plurality of column electrodes of the display matrix in the display area of the display panel so as to be wirelessly coupled to the receiving unit of the system through a direct coupling between the at least one of the plurality of row electrodes and the plurality of column electrodes of the display matrix of the display panel and the receiving unit of the system, and the response data is received by the receiving unit, the transmitting module and the receiving module establish a first data transmission path, and the row electrode and the column electrode for transmitting the display signal of the display panel and the receiving unit establish a second data transmission path, the first data transmission path and the second data transmission path constitute bi-directional data transmission between the system and the visual interface display apparatus.
