Abstract: 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.

Abstract: A display device includes a display panel including pixels coupled to a first scan line and a data line, a power supply to supply voltages, a scan driver to provide a first scan signal to the first scan line a plurality of times for a first frame period (FFP), a data driver to supply a data signal to the data line, and a timing controller to control driving of components. The FFP includes: a first active period (FAP), in which the data signal is supplied; and a first blank period (FBP), in which the data signal is not supplied. The power supply provides on-bias power having a first voltage level (FVL) in the FAP, and provides on-bias power having a second voltage level (SVL) in the FBP. The FBP following the FAP includes a first dimming period in which the on-bias power gradually changes from the FVL to the SVL.
