    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 liquid crystal display includes first and second subpixel electrodes, a common electrode and first and second reference voltage lines. The first and second subpixel electrodes are electrically connected through first and second switching elements to a data line supplied with a data voltage. The first subpixel electrode is electrically connected through a third switching element to one of the first and second reference voltage lines. A polarity of the first reference voltage is different from a polarity of the second reference voltage with respect to the common voltage supplied to the common electrode. Liquid crystal molecules are disposed between the first subpixel electrode and the common electrode and between the second subpixel electrode and the common electrode.
