Abstract: The present invention relates to a data transmission device, a data transmission method, and a display device using the data transmission device. The data transmission device comprises a multichannel V-By-One interface module, which comprises a receiving end, a transmitting end, and a buffer module arranged between the receiving end and the transmitting end. The receiving end transmits a plurality of control signals for a plurality of channels to the buffer module. The buffer module transmits one low-level control signal to the transmitting end when all the received control signals are at a low level. After receiving the one low-level control signal, the transmitting end simultaneously transmits output data corresponding to the respective channels, realizing time synchronization of all the output data, thus avoiding abnormal display of images, enhancing display quality of the images, and finally achieving the effect of optimizing and improving user experience.
