Abstract: An OLED display includes: a plurality of pixel lines each connected to a plurality of pixels, including at least two adjacent pixel lines, each pixel including: a driving thin film transistor (TFT), a first switching TFT, a second switching TFT, and an emission control TFT connected to the driving TFT, a first scan driver controlling a plurality of first switching TFTs for the two pixel lines, a second scan driver controlling a plurality of second switching TFTs for the two pixel lines, and a third scan driver configured so all of a plurality of emission control TFTs for the two pixel lines: are turned on in a programming period, maintain a turn-on state for a particular time of an emission period, and can adjust an on-time duty of the emission period after the particular time.
