An apparatus is described, the apparatus including a case, a display assembly, a chassis connected to the display assembly, a suspension component between the display assembly and the case, wherein the suspension component is configured to allow the display assembly to move relative to the case, at least one vibrating element configured to actuate the chassis to move the display assembly relative to the case to generate at least one of acoustic waves or haptic/tactile effect, and an internal cavity below the display, wherein electronic components of the apparatus are located at the internal cavity.

A flat panel speaker according to an embodiment of the disclosure includes a flat panel and a plurality of vibrators that are disposed on a back surface of the flat panel. The plurality of vibrators are disposed to avoid a location that most easily vibrates in an entire range of audio frequencies when vibration is generated in the flat panel by the plurality of vibrators. A large stationary wave with respect to the flat panel therefore does not easily occur.

A display apparatus includes: a display panel configured to display an image, a sound generation device configured to vibrate the display panel to generate sound, a supporting member on a rear surface of the display panel, and a partition surrounding the sound generation device, the partition including an edge having a partition edge contour shape that differs from a panel edge contour shape of the display panel.

A display apparatus includes: a display panel including: a transmissive area configured to transmit light incident thereon, and an emissive area configured to emit light, a light-controlling device on a rear surface of the display panel, the light-controlling device being configured to have a light transmission mode for transmitting the incident light and a light-blocking mode for blocking the incident light, the light-controlling device including: a first substrate and a second substrate facing each other, a transmission controller between the first substrate and the second substrate, the transmission controller overlapping the transmissive area, and a vibration generator between the first substrate and the second substrate, the vibration generator overlapping the emissive area.

A display apparatus includes: a display panel including: a display area configured to display an image, and a non-display area, at least one first sound generator in the display area, and at least one second sound generator in the non-display area, wherein each of the at least one first sound generator and the at least one second sound generator is configured to vibrate the display panel to generate sound toward a front of the display panel.

The present disclosure relates to a vibration generation device, a display apparatus including the vibration generation device, and a vehicle including the vibration generation device. A vibration generation device includes a piezoelectric ceramic part having a certain interval, a piezoelectric material layer between the piezoelectric ceramic parts, and an electrode part configured to provide electric field to one or more of the piezoelectric ceramic part and the piezoelectric material layer.

A display device including: a display panel having a substrate including a plurality of islands and a plurality of bridges coupling the islands to each other; and a plurality of actuators provided on first surfaces of at least one or more of the islands of the substrate. The actuators may vibrate a first area of the display panel that includes portions overlapping with the respective actuators.

A display apparatus includes: a display panel configured to display an image, at least one supporting member on a rear surface of the display panel, the at least one supporting member defining a groove, at least one sound generation device adjacent to the display panel, and a wiring, accommodated into the groove, configured to transfer a signal to the at least one sound generation device.

A display apparatus includes a display panel including a display area configured to display an image, and a non-display area, at least one first sound generator in the display area, and at least one second sound generator in the non-display area, wherein each of the at least one first sound generator and the at least one second sound generator is configured to vibrate the display panel to generate sound toward a front of the display panel.

A display apparatus includes a display panel configured to display an image; and a vibration generating device configured to vibrate the display panel to generate sound, wherein the vibration generating device includes: a first sound generating device at a rear surface of the display panel, and outputting a first sound; and a second sound generating device around the first sound generating device, and outputting a second sound.
