FORCE SENSOR AND DISPLAY DEVICE INCLUDING THE SAME
FIG2 is an exploded perspective view of the display device according to the embodiment
The force sensors 100 and 200 may be disposed to overlap at least one edge of the display panel 30. A plurality of force sensors 100 and 200 may be provided. As illustrated in the drawings, the force sensors 100 and 200 include a first force sensor 100 overlapping a first long edge (first long side LSi) of the display panel 30 and a second force sensor 200 overlapping a second long edge (second long side LS2) of the display panel 30. In FIG2, the force sensors 100 and 200 are disposed in the second area DR2 (i.e., the curved portion) of the display device 1. For example, when the second area DR2 is divided into first and second subareas, the first sensor 100 may be disposed in the first subarea, the second force sensor 200 may be disposed in the second subarea, and the first area DR1 is disposed between the subareas. However, the force sensors 100 and 200 are disposed in the second area DR2 in alternate embodiments. In an exemplary embodiment, any one of the force sensor 100 and 200 is omitted. For example, in some embodiments only one of the force sensor 100 or force sensor 200 is present. The position where the force has been applied may be identified through the touch member 20 (see FIG2). That is, a touch electrode may be disposed in regions of the touch member 20 which overlap the force sensors 100_4 and 200_4 to detect the presence or absence of a touch and the position of the touch, and the presence or absence of a force and the magnitude of the force may be measured by the force sensors 100_4 and 200_4 and used as an input signal.

['1. A display device comprising: a display panel; and a first force sensor disposed adjacent to a first edge of the display panel, the first force sensor extending along the first edge, wherein the first force sensor comprises: a first sensing region; a second sensing region located adjacent the first sensing region and having a larger area than the first sensing region; a first force concentration bump overlapping the first sensing region; and a second force concentration bump overlapping the second sensing region and spaced apart from the first force concentration bump.', '18. The display device of any one of claims 1 to 16, comprising a recess disposed at an inner side of the first force sensor, wherein the first sensing region is disposed on a first side of the recess and the second sensing region is disposed on a second side of the recess; optionally wherein the recess is notch-shaped; optionally further comprising a bracket which houses the display panel and the first force sensor, the bracket comprising a connect hole through which a connector passes, wherein the recess bypasses the connect hole in an outward direction.']
