Visual interface system

A visual interface system, comprising:

• a matrix display apparatus, comprising:
• a controller and drivers, the controller configured to receive and encode a source data into an image data and a transmission data;
• and
• a matrix substrate including:
• a substrate, having a front surface and a back surface, wherein the front surface faces a viewer watching images displayed on the matrix display apparatus, and the back surface faces away the viewer when the viewer is watching images displayed on the matrix display apparatus;
• a plurality of pixel units, formed on the back surface of the substrate;
• and
• a plurality of line electrodes intersected and formed on the back surface of the substrate, electrically connected to the pixel units to form a display matrix, wherein the image data is through the line electrodes to the pixel units so that the matrix display apparatus presents an optical image, and the transmission data are to be coupled electrically from the display matrix and transmit wirelessly;
• and
• an operation apparatus, configured to be operated on the front surface of the substrate to receive the transmission data from the display matrix formed on the back surface of the substrate by wirelessly coupling, and configured to obtain the source data by decoding the transmission data.
