US 2023/0141258 A1 · DISPLAY APPARATUS

Abstract

A display apparatus including a display panel, an input sensor having an active area having a plurality of electrodes disposed therein and at least a portion of which overlaps the display area, and a non-active area which overlaps the non-display area. The active area has a central area and a peripheral area disposed outward from the central area. The plurality of electrodes include center electrodes which are disposed in the central area and peripheral electrodes which are disposed in the peripheral area and have a surface area less than that of the center electrodes. Each of the center electrodes includes a sensing pattern and a floating pattern, and each of the peripheral electrodes includes substantially only the sensing pattern. Thus, an embodiment of the inventive concept may provide the display apparatus that includes an input sensor having improved sensitivity in a peripheral area.

the plurality of electrodes comprises:
a plurality of first electrodes;
and
a plurality of second electrodes disposed corresponding to the plurality of first electrodes;
some of the first electrodes or the second electrodes comprise center electrodes, which are disposed in the central area, and peripheral electrodes, which are disposed in the peripheral area;
and
the dummy pattern is adjacent to an edge of one of the peripheral electrodes.
