Abstract: A display panel includes a base layer, a circuit layer, a light emitting element, a pixel defining film, an encapsulation layer, and a first dam. The base layer may include a display area and a non-display area adjacent to the display area. The encapsulation layer may include a first inorganic film, an organic film, and a second inorganic film. The first dam may be disposed between the first inorganic film and the second inorganic film, and outside the organic film. The first dam may overlap the non-display area and the pixel defining film on a plane. Therefore, in the display panel of an embodiment, the non-display area may be reduced.

Abstract: Among data voltages applied to a plurality of pixels on a display panel, a first data voltage is shifted from a first original data voltage by a first value, a second data voltage is shifted from a second original data voltage by a second value, and a third data voltage is shifted from a third original data voltage by a third value to compensate for AC and DC afterimages. A common voltage generator provides an optimal common voltage for the third data voltage when the temperature of the liquid crystal panel assembly is lower than a reference temperature and provides an optimal common voltage for the first data voltage or the second data voltage when the temperature of the liquid crystal panel assembly is higher than or equal to the reference temperature. The first, second, and third values correspond to respective kickback voltages of the respective gray level data voltages.
