Abstract: A display apparatus includes: a display panel including a plurality of pixels and a panel driver for applying a data voltage to pixels by the same pixel-column and performing a sensing operation, which senses the pixels receiving the data voltage. The plurality of pixels include first pixels having a first color and second pixels having a second color different from the first color. After the sensing operation is performed on a first odd-numbered group of the first pixels, the sensing operation is performed on a first even-numbered group of the first pixels. After the sensing operation is performed on the first even-numbered group of the first pixels, the sensing operation is performed on a second odd-numbered group of the second pixels. After the sensing operation is performed on the second odd-numbered group, the sensing operation is performed on a second even-numbered group of the second pixels.
