Abstract: A display device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.

Abstract: A scan driver includes a control unit, a first output unit, a second output unit, and a masking control unit. The control unit outputs a first control signal to a first control node and outputs a second control signal to a second control node. The first output unit is connected to the first control node, a first output terminal, and a first voltage terminal, and operates in response to the first control signal. The second output unit is connected to the second control node, the first output terminal, and a second voltage terminal, and operates in response to the second control signal. The masking control unit is connected between an input terminal, to which a clock signal is input, and the first control node and controls a voltage level of the first control signal in response to a masking enable signal.

Abstract: A display device includes a display panel, a power supply unit, and a low frequency offset compensator. The display panel includes a plurality of pixels. The power supply unit generates a first initialization voltage and a second initialization voltage and provides the first initialization voltage and the second initialization voltage to the pixels. The low frequency offset compensator selectively applies an offset to the second initialization voltage when the display panel is driven at a low frequency.

Abstract: A display device includes a display panel including a first partial panel region and a second partial panel region, and a panel driver which drives 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. In a case where 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.
