    Abstract: An input sensing device includes driving electrodes and sensing electrodes, and an analog front-end which processes sensing signals from the sensing electrodes to output a differential output value. The analog front-end includes a first charge amplifier which differentially amplifies first and second sensing signals from two sensing electrodes to first and second input terminals, thus outputting first and second differential signals through first and second output terminals, a second charge amplifier which differentially amplifies the first and second differential signals, thus outputting third and fourth differential signals, a first demodulation circuit which filters the first and second differential signals in a first mode and filters each of the third and fourth differential signals in a second mode, and a first analog-to-digital converter which outputs a first sensing value based on at least one output signal of the first demodulation circuit.

    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.
