Claim:
1. A display apparatus, comprising: a display unit including a plurality of pixel circuits, each of which includes a light emitting element, the display unit displaying an image corresponding to a data signal supplied on a basis of display data, the display unit emitting light during a vertical interval including a display interval and a sensing interval; a scan driver controlling, for each pixel circuit, light emission of the light emitting element at the display interval, during which the image is displayed; a sense driver sensing the light emitting element at the sensing interval, during which the light emitting element is sensed using a sensing operation, the sensing interval including an emission interval during which the light emitting element of the target pixel circuit selectively emits light according to the sensing operation; and a data driver compensating the display data when the sensing operation is performed on a target pixel circuit among the plurality of pixel circuits, the data driver compensating the display data by setting a light emission amount of the light emitting element of the target pixel circuit to be an amount obtained by subtracting a sensing light emission amount, which is a light emission amount of the light emitting element of the target pixel circuit during the sensing interval, from a display light emission amount, which is a light emission amount of the light emitting element of the target pixel circuit before the compensation.
