Abstract: An electronic device includes a display panel and an input sensor disposed on the display panel and having a first sensing electrode extending in a first direction. The first sensing electrode includes a first trunk portion extending in the first direction and a first branch portion extending from the first trunk portion in a second direction crossing the first direction. The first branch portion includes a plurality of first branches and a plurality of second branches. The first branches extend in a direction opposite to a direction in which the second branches extend in the second direction, and the number of the first branches is equal to the number of the second branches.

Abstract: Disclosed is an input-sensing part which includes first sensing electrodes each receiving a driving signal every frame, and second sensing electrodes insulated from the first sensing electrodes and extending to intersect the first sensing electrodes. A cycle of the driving signal is defined by a period of a first signal and a period of a second signal, which is a signal following the first signal and is lower in level than the first signal. A frequency of the driving signal is variable. When the frequency of the driving signal changes, the first period is fixed, and the second period changes.
