A feedback structure for an organic light-emitting diode display comprises an organic light-emitting diode panel, a driver chip and a signal transmission line group. The organic light-emitting diode panel includes a signal input terminal group and a signal feedback term connected to the ground. The driver chip includes a power input port connected to an external power source, a signal input port, and a feedback port connected to the ground. The signal transmission line group is electrically connected between the signal input terminal group and the signal output port. By such arrangements, it can ensure a stable segment control signal or avoid damage to the driver chip.
