Abstract: A display device includes a display unit which includes pixels, an emission driver which applies an emission control signal for allowing the pixels to emit light, and a signal controller which receives a data enable signal including an active period and a blank period during which an image signal is inputted and outputs a control signal for controlling the emission driver such that an emission period of the pixels is changed in response to a blank period.

Abstract: A display device includes a display panel, a data driver, a gate driver, and a controller. The display panel includes a plurality of pixels. The data driver provides data voltages to the plurality of pixels through data lines during an active period of a frame period and provides a blank voltage to the plurality of pixels through the data lines during a blank period of the frame period. The gate driver provides a gate-on voltage to the plurality of pixels through gate lines during the active period and provides a gate-off voltage to the plurality of pixels through the gate lines during the blank period. The controller controls the data driver and the gate driver. The blank voltage increases and the gate-off voltage increases, when a time in the blank period reaches a predetermined time.

Abstract: A display device may include a backlight unit, a display panel, and a backlight driver, and a panel driver. The backlight unit may include light source blocks including a first light source block. The display panel may include dimming regions including a first dimming region and respectively overlapping the light source blocks. The first dimming region may overlap the first light source block. The backlight driver may control a turn-on period and a turn-off period of each of the light source blocks. The panel driver may sequentially provide scan signals to the dimming regions for controlling light transmission of the dimming regions. A turn-off period of the first light source block may start before a scan period of the first dimming region and may end after the scan period of the first dimming region. The first dimming region may receive corresponding scan signals in the scan period.
