Abstract: A display device includes a display panel and an input sensing part disposed on the display panel. The input sensing part includes first sensing electrodes extending in a first direction and arranged in a second direction crossing the first direction, first lines connected to the first sensing electrodes, second sensing electrodes extending in the second direction and arranged in the first direction, and second lines connected to the second sensing electrodes. The second lines include second-first lines defined as j-th to k-th second lines, and the first lines are connected to the second-first lines.

Abstract: An input sensing device includes driving electrodes and sensing electrodes, analog front ends to process sensing signals provided from the sensing electrodes to output demodulation signals, a multiplexer connected to the analog front ends to select one of the demodulation signals, and an analog-to-digital converter to convert an analog output signal provided from the multiplexer into a digital sensing value. Sampling rates of the analog-to-digital converter may be different from each other in different operating modes. Resolutions of the analog-to-digital converter may be different in different operating modes. The input sensing device may be incorporated within a display device for displaying images.
