摘要： A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver configured to drive the display panel. The panel driver determines a first driving frequency for the first partial panel region and a second driving frequency for the second partial panel region. When the first driving frequency and the second driving frequency are different from each other, the panel driver sets a boundary portion including a boundary between the first partial panel region and the second partial panel region, and determines a third driving frequency for the boundary portion to be between the first driving frequency and the second driving frequency.
