Abstract: An electronic device includes: a display panel configured to display an image; an input sensor on the display panel and comprising a first sensing electrode and a second sensing electrode that is electrically insulated from the first sensing electrode, the input sensor being configured to sense a first input in a first mode and to sense a second input in a second mode; and an input device configured to provide the second input to the input sensor, wherein at least one of the first or second sensing electrodes comprises: a main mesh pattern in a crossing area in which the first and second sensing electrodes cross each other; and a sub mesh pattern in a non-crossing area on which the first and second sensing electrodes do not cross each other and which has a size different from that of the main mesh pattern.

Abstract: An electronic device includes a display layer, a sensor layer disposed on the display layer and including a first sensing pattern and a second sensing pattern spaced apart from the first sensing pattern. The first sensing pattern includes a first-first group including a first-first pattern and a first-second pattern spaced apart from the first-first pattern in a first oblique direction, a first-second group including a first-third pattern and a first-fourth pattern spaced apart from the first-third pattern in a second oblique direction crossing the first oblique direction. The second sensing pattern includes a second-first group adjacent to the first-first group and including a second-first pattern and a second-second pattern spaced apart from the second-first pattern in the second oblique direction and a second-second group including a second-third pattern and a second-fourth pattern spaced apart from the second-third pattern with the second-first group interposed therebetween in the first oblique direction.
