Abstract
A method for driving a display apparatus, according to one or more embodiments of the present invention, provides a luminance representative value of a unit light-emitting block that may be determined from an external image signal of a plurality of image blocks corresponding to the unit light-emitting block including a plurality of light sources. A luminance compensation value of the unit light-emitting block may be calculated by compensating the luminance representative value. Pixel data of the external image signal in a central area of the unit light-emitting block and a boundary area may be corrected based on the luminance compensation value. A driving signal may be provided to the unit light-emitting block based on the luminance compensation value. Accordingly, a phenomenon in which a boundary of the unit light-emitting block is visible is removed so that the display quality of all image may be enhanced.
