    Abstract: A display device includes a display panel; a pressure sensor disposed on the display panel; and a lower bracket. The pressure sensor is disposed between the display panel and the lower bracket and is disposed on the lower bracket. The pressure sensor includes a first substrate, a first pressure sensing layer disposed between the first substrate and the lower bracket, a first driving electrode disposed between the first pressure sensing layer and the lower bracket, and a first sensing electrode spaced apart from the first driving electrode. A gap is present between the first pressure sensing layer, and the first driving electrode and the first sensing electrode.

    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.
