  • Publication number: 20140354606
    Abstract: A display device includes a printed circuit board, a timing controller, a display panel, a plurality of source drivers, and a plurality of traces. The timing controller is disposed on the printed circuit board for generating a plenty of differential pairs. The source drivers which are disposed on the display panel for receiving the differential pairs are respectively assigned with an identification number, in which each of the source drivers determines a polarity of the differential pair received according to a corresponding identification number assigned to the source driver. Flexible printed circuit boards are connected to the printed circuit board and the display panel, and each of the flexible printed circuit boards is corresponding to some of the source drivers. The traces carrying the differential pairs are connected to the timing controller and to the source drivers through the flexible printed circuit boards.
