Abstract

A display device includes a plurality of pixel rows including a plurality of pixel circuits; a scan driver supplying scan signals to the plurality of pixel rows; and a data driver supplying a data voltage to the plurality of pixel circuits of the plurality of pixel rows, wherein the plurality of pixel circuits each include driving transistors and an organic light emitting diode which emit light depending on a current flowing in the driving transistors, the plurality of pixel rows are divided into a plurality of blocks, each of the blocks including at least one pixel row, and a period for which the data voltage is written in the plurality of pixel circuits in a first block among the plurality of blocks and a period for which a threshold voltage of the driving transistors of the plurality of pixel circuits in a second block temporally close to the first block is compensated partially overlap each other.
