Abstract: The present disclosure relates to display devices, controllers, and display driving methods, and more specifically, to a display device, a controller, and a display driving method capable of selectively overdriving only a pattern of an image or sub-pixel regarded as a more likely lack of charge. Through this, there is provided an effect of preventing excessive compensation due to unnecessary overdriving.

Abstract: Embodiments of the present disclosure relate to a gate driving circuit, a display device, and a method for driving a display device. It is possible to reduce deterioration of the transistor controlled by a first QB node and a second QB node by alternately driving the first QB node and the second QB node of a gate circuit. In addition, by sensing a deterioration deviation between a transistor controlled by the first QB node and a transistor controlled by the second QB node and adjusting a driving period of the first QB node and a driving period of the second QB node based on the sensing result, it is possible to maximize or at least increase the lifetime of the transistor controlled by the first QB node and the transistor controlled by the second QB node, thereby improving the reliability of the gate circuit.

Abstract: The present disclosure relates to a display device capable of preventing light-emitting elements in a display panel from being deteriorated. A power supply circuit includes a plurality of first power supply lines each of which extends in a first direction and a plurality of second power supply lines each of which extends in a second direction intersecting the first direction, in which the second power supply lines are electrically connected with the first power supply lines.
