A display device includes a display panel. The display panel includes pixels connected to gate lines and data lines. A sensor overlaps the display panel. A gate driver is configured to provide a gate signal to the gate lines. In a first mode, the gate driver provides the gate signal to the gate lines using progressive scanning. In a second mode, the gate driver provides the gate signal using interlaced scanning, and the sensor operates in a period allocated between periods in which a first interlaced scanning operation and a second interlaced scanning operation are performed within one frame period.

Display device

A display device includes: a pixel including a first transistor connected between a first node and a second node to generate a driving current; an emission driver supplying an emission control signal; a scan driver supplying first to fourth scan signals in a period in which the emission control signal is supplied; a data drive supplying a data signal; a power supply supplying a voltage of a first power source; and a timing controller controlling driving of the scan driver, the emission driver, the data driver, and the power supply The first scan signal controls a timing at which the voltage of the first power source is supplied to the first node or the second node. The power supply changes a level of the voltage of the first power source in one frame period.

Pixel and display device having the same

A display device includes a pixel including a first transistor coupled between a first node and a second node, an emission driver supplying an emission control signal at a first frequency to an emission control line, a scan driver supplying first to fourth scan signals respectively to first to fourth scan lines, a data driver supplying a data signal to a data line, and a timing controller. The first scan signal controls a timing at which a voltage of a first power source is supplied to the first node or the second node, and the second scan signal controls a timing at which a first electrode of the first transistor and a gate electrode of the first transistor are coupled to each other. The scan driver controls a bias state of the first transistor by supplying, plural times, the first and second scan signals in a non-emission period.
