Abstract

The present invention provides an electrical processing apparatus and method for electrically processing a display panel having an organic light-emitting layer. The method for electrically processing a display panel having an organic light-emitting layer includes dividing a light-emitting region of the display panel into a plurality of regions; and applying a voltage to at least one region of the plurality of regions where an amplitude of the voltage exceeds an amplitude of a driving voltage of the display panel. The electrical processing apparatus includes a display panel comprising an organic light-emitting layer, a light emitting region, and a plurality of regions, the plurality of regions being defined by dividing the light emitting region; a jig for holding the display panel; and a current supplying portion, wherein the current supplying portion supplies a current individually to each of the plurality of regions.
