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.

Abstract: A display apparatus includes a display panel, a data driving circuit, and a gate driving circuit. The display panel is configured to display an image and includes a gate line and a data line. The data driving circuit is configured to output a data signal to the data line. The gate driving circuit is configured to output a gate signal to the gate line and to control a kick-back time of the gate signal according to a temperature of the display panel. The kick-back time is a time when the gate signal is decreased from a gate on voltage to a kick-back voltage that is between the gate on voltage and a gate off voltage.

Abstract: A display device includes gate lines, data lines, pixels, a gate driver, a data driver, and a timing controller. The gate lines extend in a first direction. The data lines extend in a second direction crossing the first direction. Each of the pixels is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines. The gate driver is configured to drive the gate lines. The data driver is configured to drive each data line of the data lines in response to a corresponding data signal. The timing controller is configured to, in response to an image signal and a control signal, apply the corresponding data signals to the data driver and control the gate driver. Each corresponding data signal reflects a kickback compensation value corresponding to a distance between the gate driver and the corresponding data line in the first direction.
