Scan driving circuit, driving controller and display device including them

A display device comprising:

• a display panel including a first pixel connected to a first initialization scan line and a first compensation scan line, a second pixel connected to a second initialization scan line and a second compensation scan line, a third pixel connected to a third initialization scan line and a third compensation scan line, and a fourth pixel connected to a fourth initialization scan line and a fourth compensation scan line;
• a scan driving circuit which provides a first initialization scan signal to the first initialization scan line and the second initialization scan line in common, provides a second initialization scan signal to the third initialization scan line and the fourth initialization scan line in common, and provides a first compensation scan signal, a second compensation scan signal, a third compensation scan signal, and a fourth compensation scan signal to the first compensation scan line, the second compensation scan line, the third compensation scan line, and the fourth compensation scan line, respectively;
• and
• a driving controller which controls the scan driving circuit,
• wherein a first time from a time point at which the first compensation scan signal transitions from an inactive level to an active level to a time point at which the second compensation scan signal transitions from the inactive level to the active level is less than a second time from a time point at which the second compensation scan signal transitions from the inactive level to the active level to a time point at which the third compensation scan signal transitions from the inactive level to the active level.

A scan driving circuit comprising:

• a first scan driving circuit which provides a first initialization scan signal to a first initialization scan line and a second initialization scan line;
• and
• a second scan driving circuit which provides a first compensation scan signal to a first compensation scan line and provides a second compensation scan signal to a second compensation scan line,
• wherein a delay time from a time point at which the first initialization scan signal transitions from an active level to an inactive level to a time point at which the first compensation scan signal transitions from the inactive level to the active level is less than one horizontal period.

A driving controller comprising:

• an image processor which outputs an output image signal in response to an input image signal and a control signal;
• and
• a control signal generator which outputs a data control signal and a scan control signal in response to the control signal,
• wherein the image processor outputs the output image signal for compensating for the input image signal by using a first compensation value when the input image signal corresponds to a first row of pixels, and
• wherein the image processor outputs the output image signal for compensating for the input image signal by using a second compensation value when the input image signal corresponds to a second row of pixels.
