    Abstract: A display device includes a touch screen panel folded based on a folding axis, and at least one touch electrode on the folding axis. Each of the touch electrodes on the folding axis may include a graphene layer, a metal mesh layer, and an adhesion metal mesh layer. The grapheme layer may be along the folding axis on a transparent substrate. The first metal mesh layer may be on the transparent substrate to adhere to a lateral surface of the first graphene layer. The first adhesion metal mesh layer may be on a boundary portion between the first graphene layer and the first metal mesh layer.

    Abstract: A display device including a display panel including pixels that emit light on a frame basis. An input sensing unit includes driving electrodes and sensing electrodes. A driving signal generator is configured to provide driving signals to the driving electrodes. Analog front-ends are configured to receive sensing signals depending on the driving signals from the sensing electrodes. A signal processor is configured to detect touch input, based on differential output values of the analog front-ends. The driving signal generator provides the driving signals to the driving electrodes while avoiding a period in which a pulse of a vertical synchronization signal defining start of the frame is generated.

    Abstract: An input sensing device includes a first base layer, a plurality of first sensing electrodes, a plurality of second sensing electrodes, a plurality of third sensing electrodes, and a plurality of fourth sensing electrodes. The first sensing electrodes are arranged on the first base layer along a first direction. The second sensing electrodes are arranged on the first base layer in different rows from the first sensing electrodes. The third sensing electrodes are arranged on the second sensing electrodes along a second direction different from the first direction. The third sensing electrodes overlap the second sensing electrodes. The fourth sensing electrodes are arranged on the same layer as the third sensing electrodes and overlap the first sensing electrodes. A constant voltage is applied to the third sensing electrodes during a touch pressure sensing operation.
