1. A display panel, comprising:
a plurality of first pixels on a first region having a first resolution;
a plurality of second pixels on a second region having a second resolution greater than the first resolution; and
a test circuit configured to provide one or more test voltages to the plurality of first pixels and the plurality of second pixels, wherein the test circuit includes:
a first test circuit configured to provide the plurality of first pixels with a first voltage; and
a second test circuit configured to provide the plurality of second pixels with a second voltage different from the first voltage, wherein the first voltage causes the plurality of first pixels to exhibit a target brightness which is equal to a target brightness exhibited by the plurality of second pixels as a result of the second voltage.
