Abstract
A display device includes a display panel including a first image unit and a second image unit, a data driver which applies data voltages to the display panel, a first scan driver which applies write scan signals to the display panel, a second scan driver which applies compensation scan signals and initialization scan signals to the display panel, and a masking part connected to the second scan driver and which selectively applies the initialization scan signals to the second image unit.
Claims20
A display device comprising:
- a display panel including a first image unit and a second image unit;
- a data driver which applies data voltages to the display panel;
- a first scan driver which applies write scan signals to the display panel;
- a second scan driver which applies compensation scan signals and initialization scan signals to the display panel;
- and
- a masking part connected to the second scan driver and which selectively applies the initialization scan signals to the second image unit.

A display device comprising:
- a display panel including a first image unit with pixels in first to (i−1)-th rows and a second image unit with pixels in i-th to m-th rows;
- a data driver which applies data voltages to the display panel;
- a first scan driver which applies write scan signals to the display panel;
- a second scan driver which applies compensation scan signals and initialization scan signals to the display panel;
- and
- a masking part connected to the second scan driver,
- wherein the second scan driver comprises m+c compensation-initialization stages which output the compensation and initialization scan signals,
- wherein the masking part comprises a plurality of masking circuits connected to i-th to (i+c−1)-th compensation-initialization stages of the m+c compensation-initialization stages, respectively, and the plurality of masking circuits selectively output i-th to (i+c−1)-th initialization scan signals received from the i-th to (i+c−1)-th compensation-initialization stages, respectively,
- wherein i, m, c are natural numbers, and i is 2 or more and equal to or less than m.
