Abstract: A display device can include a left ripple transistor provided in a left stage to remove ripple occurring in a Q node of the left stage, and a right ripple transistor provided in a right stage to remove ripple occurring in a Q node of the right stage. These ripple transistors perform an on operation and an off operation repeatedly and simultaneously.

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