Abstract: A display apparatus includes a plurality of pixels arranged in rows and columns with a plurality of gate lines extending in a first direction and connected to the pixels, and a plurality of data lines connected to the pixels. In the display apparatus, certain data lines disposed between pixels are arranged in a first row to an e-th row with such data lines including a plurality of column data lines extending in a second direction crossing the first direction and a plurality of row data lines extending in the first direction. The row data lines are electrically connected to the column data lines. The column data lines extend in the second direction between pixels arranged in the e-th row to an f-th row, where e and f are natural numbers and f is equal to or greater than e.

Abstract: A display device includes a display panel, a light emission control driver, and a brightness compensator. The display panel includes first pixels in a first display area and second pixels in a second display area. The light emission control driver controls light emission times of the first and second pixels. The brightness compensator detects a degree of deterioration of the first pixels and a degree of deterioration of the second pixels. The degrees of deterioration of the first and second pixels are different. The brightness compensator controls the light emission control driver to set the light emission times of the first pixels differently from the light emission times of the second pixels based on the different degrees of deterioration of the first and second pixels.

Abstract: A display apparatus includes a first pixel, a second pixel, and a dummy pixel. The first pixel includes a first light-emitting device connected to a first pixel circuit through a first node. The second pixel is in a same row as the first pixel and includes a second light-emitting device connected to a second pixel circuit through a second node. The dummy pixel includes at dummy pixel circuit with a third node. The controller outputs a first control signal having a first level or a second level based on a first pixel grayscale value corresponding to the first pixel and a second pixel grayscale value corresponding to the second pixel. A switch circuit electrically connects the first node, the second node, and a third node when the first control signal has the first level.
