Abstract: A display device includes: a pixel including a light emitting element, a first capacitor connected between a first node and a second node, and a second capacitor connected between the second node and a third node. The pixel further includes: a first transistor connected between the second node and the light emitting element to operate depending on potential of the first node; a second transistor connected between the third node and a data line to operate depending on a first scan signal; a third transistor connected between the third node and the second transistor to operate depending on a light emitting control signal; a fourth transistor connected between a reference voltage line and a first node to operate depending on the second scan signal; and a fifth transistor connected between the reference voltage line and the third node to operate depending on a third scan signal.

Abstract: A display device includes a display panel and an input sensor. The input sensor may include a first sensing electrode, a signal line electrically connected to a first terminal of the first sensing electrode, a first line at least partially overlapping the first sensing electrode and extending in the same direction as the first sensing electrode in the active area, and a first switching element defining a first current path in the first sensing electrode and the first line or blocking the first current path.

Abstract: A backlight device includes a substrate and a plurality of light emitters on the substrate. Each of the plurality of light emitters includes a brightness controller disposed on the substrate, and a pad unit disposed on the substrate. The brightness controller generates a light-emission current, a light-emitting diode is allowed to be disposed on the pad unit, and the light-emitting diode emits light based on the light-emission current.
