Abstract: A display apparatus can include a display panel configured to display a black image and a real image, a gate driver configured to display gate signals to a plurality of gate lines provided in a display area of the display panel, and a controller configured to control the gate driver. Here, one-frame period for displaying the black image is shorter than one-frame period where the real image is displayed. Further, the gate driver can include a plurality of stages configured to supply the gate signals to the plurality of gate lines, and a plurality of dummy stages connected directly between the plurality of stages and the controller. In addition, gate start signals for driving the plurality of stages are supplied to the plurality of dummy stages by the controller.

Abstract: A display device includes light emitting elements in an active area and each light emitting element includes an anode, a light emitting layer, and a cathode; signal lines in a non-active area outside the active area; an encapsulation unit on the light emitting elements and the signal lines; touch electrodes on the encapsulation unit in the active area; first lines on the encapsulation unit in the non-active area and electrically connected to the touch electrodes; a second line outside the first lines; first auxiliary lines under the first lines and respectively electrically connected to a part of the first lines through first electrodes; and a second auxiliary line under the second line and electrically connected to the second line through a second electrode. The cathode is on an entire surface of the active area and extends to a shielding area of the non-active area.
