A bulk acoustic resonator includes a resonance portion including a first electrode, a piezoelectric layer disposed on the first electrode along a height direction, and a second electrode disposed on the piezoelectric layer along the height direction. The resonance portion includes an overlapping region in which the first electrode, the piezoelectric layer, and the second electrode overlap each other along the height direction. The overlapping region includes a central portion and an edge portion disposed outside the central portion, and including a first edge portion and a second edge portion. A height of the second electrode of the first edge portion and a height of the second electrode of the second edge portion are lower than a height of the second electrode of the central portion along the height direction, and are different from each other along the height direction.

Bulk acoustic resonator

Disclosed is a display apparatus. The display apparatus includes an input interface, a display panel, at least one memory configured to store instructions, and at least one processor configured to execute the instructions to identify an object included in an image corresponding to the image signal, adjust a dimming value of an area of the display panel corresponding to the object so that a brightness of the object is increased, and control the display panel to display the image based on the adjusted dimming value.
