摘要： A display device system circuit and a display device are provided. The display device system circuit includes a power supply, a plurality of functional circuit modules and a plurality of ground wires corresponding to the plurality of functional circuit modules, respectively. Operating current input ends of the plurality of functional circuit modules are electrically connected to a positive electrode of the power supply, respectively. An operating current output end of each of the functional circuit modules is electrically connected to a negative electrode of the power supply via a corresponding ground wire. The functional circuit modules will not be interfered with each other, avoiding causing abnormal displaying by signal coupling between the functional circuit modules.
