    Abstract: A touch sensor includes a base layer, a first electrode unit, second electrode units, and a first strain gauge. The first electrode unit includes first touch electrodes arranged on the base layer along a first direction and electrically connected to each other along the first direction. The second electrode units are spaced apart from one another along the first direction. Each of the second electrode units includes second touch electrodes arranged on the base layer along a second direction intersecting the first direction and electrically connected to each other along the second direction. Each of the second touch electrodes includes a first opening. The first strain gauge includes first resistance lines electrically connected to each other along the first direction. Each of the first resistance lines is disposed in a respective first opening disposed in a first row among the first openings.

    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.
