Abstract
A test device for a display panel and a method of testing the same are provided. The test device for a display panel includes a luminance measurement unit that measures a luminance value of a display panel including a plurality of pixels, and a controller that determines a voltage value of a data signal corresponding to a target luminance value, receives a measured luminance value of a pixel to which the data signal is supplied from the luminance measurement unit from among the plurality of pixels, compares the measured luminance value and the target luminance value, and outputs a control signal that changes a first power source voltage value supplied from a power source voltage supply unit to the pixel until the measured luminance value does not coincide with the target luminance value.
