Abstract: An input sensing device includes an input sensing panel including driving electrodes and sensing electrodes, a driving signal generator that provides driving signals to the driving electrodes, respectively, and a sensing unit that receives sensing signals according to the driving signals from the sensing electrodes, and determines whether a touch is performed based on the sensing signals. Each of the driving signals includes a sinusoidal wave, and frequencies of at least some of the driving signals are different from each other.

Abstract: A display device includes a display panel having a display area and a non-display, an input sensing unit overlapping the display panel, a cover window overlapping the input sensing unit, a first electrode overlapping the non-display area and disposed between the cover window and the input sensing unit, a second electrode disposed between the cover window and the first electrode, a pressure-sensitive member disposed between the first electrode and the second electrode, and a first spacer and a second spacer both disposed between the first electrode and the second electrode. A first minimum thickness of the pressure-sensitive member corresponds to the first spacer. A second minimum thickness of the pressure-sensitive member corresponds to the second spacer and is unequal to the first minimum thickness of the pressure-sensitive member.

Abstract: A display device includes a display panel configured to display an image. A window laces the display panel and includes a transparent display area configured to transmit the image displayed on the display panel therethrough. A non-display area at least partially surrounds the display area. A light-blocking pattern layer is disposed on the non-display area of the window. A touch member is disposed between the display panel and the window and includes a voltage line. A pressure sensing wiring is disposed between the touch member and the window and at least partially overlaps the voltage line. The voltage line and the pressure sensing wiring overlap the light-blocking pattern layer.

Abstract: A touch sensing device includes a base layer, a touch electrode layer, a first reinforcing member, and a touch circuit board. The base layer includes a main area and a protruding area protruding from the main area in a first direction. The touch electrode layer is disposed on a surface of the base layer. The first reinforcing member is disposed on a surface of the protruding area. The touch circuit board is electrically connected to the touch electrode layer. The protruding area includes a bending area and a pad area. The bending area is bent downward. The pad area extends from the bending area in the first direction and overlaps the base layer in a second direction intersecting the first direction in a bent state of the bending area. The touch circuit board is attached to the pad area.

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.
