Abstract

A display device includes a display panel having a first emission region and a second emission region that is distinct from and mutually exclusive to the first emission region and surrounds the first emission region. The display device includes a first plurality of light emitters arranged in the first emission region, a plurality of activation lines for the first emission region, a second plurality of light emitters arranged in the second emission region, and a plurality of activation lines for the second emission region. A single activation line of the plurality of activation lines for the first emission region is electrically coupled with a first number of light emitters in the first emission region and a single activation line of the plurality of activation lines for the second emission region is electrically coupled with a second number, distinct from the first number, of light emitters in the second emission region.
