1. A display manufacturing system comprising:
a plurality of display devices, each including a display panel which displays an image;
a driving voltage measurer which calculates a saturation voltage corresponding to a luminance of the image displayed on the display panel by changing a driving power voltage for driving the display panel; and
a processor which calculates a current density and a degradation weight value based on the saturation voltage, and controls the display panel included in each of the plurality of display devices based on the current density and the degradation weight value,
wherein the processor calculates the degradation weight value, based on a center value of the current density of the display panel included in each of the plurality of display devices and the current density of a target display panel.
