Abstract: A display apparatus may include a first plurality of pixels, a substrate, a first signal line, and a load matching device. The substrate may include a first opening, a first non-display area, and a main display area. The first non-displaying area may at least partially surround the first opening. The main display area may support the first plurality of pixels. The first signal line may be electrically connected to the first plurality of pixels, may overlap the main display area, and may overlap the first non-display area. The load matching device may overlap the first non-display area and may provide a first electrical load to the first signal line.

Abstract: A display device including a touch display panel, a roller housing, a touch bar, and a panel driver. The touch display panel includes a plurality of pixels and a plurality of touch sensing elements. At least a portion of the touch display panel is rolled around a roller. The roller housing is configured to receive the roller and has an opening configured to receive the touch display panel. The touch bar is disposed between the roller housing and the touch display panel and contacts the touch display panel. The panel driver divides a display portion of the touch display panel into a display area and a non-display area according to positions of touch sensing elements contacting the touch bar. The panel driver deactivates at least a portion of the non-display area.
