A data transfer device of a display equipment and a data transfer method are provided. The data transfer device of the display equipment includes a display panel, a first transfer connector, a second transfer connector, a configuration switch and a control unit. The first and the second transfer connector are in line with a universal serial bus (USB) protocol including a plurality of data paths. When a first electronic device is connected to the first transfer connector, the control unit separates the data paths of the first transfer connector into at least one video data path and at least one data-transferring data path dynamically. A video signal of the first electronic device is transferred to the display panel through the video data path, and the first electronic device and the second electronic device transfer data to each other through the data-transferring data path.
