A display apparatus includes a display module having a display panel configured to display an image, a sound generating device configured to vibrate the display panel, an adhesive member connected between a rear surface the display panel and the sound generating device, and a structure configured to support the sound generating device, wherein the structure is connected to at least a portion of the sound generating device and a portion of the rear surface the display panel.

Display apparatus

A display apparatus includes a display module including a display panel configured to display an image and a sound generating module on a rear surface of the display panel, the sound generating module includes a vibration generating device, a circuit board on a lower surface of the vibration generating device, a first adhesive member between the circuit board and the vibration generating device, and a second adhesive member between the vibration generating device and the display panel, an elastic modulus of the second adhesive member differing from an elastic modulus of the first adhesive member.

A display apparatus includes a display panel configured to display an image, a circuit part including a printed circuit board disposed spaced apart from a first portion of the display panel and connected to the display panel, a first vibration device disposed at a rear surface of the display panel, and a second vibration device disposed at a rear surface of the printed circuit board.

A display apparatus includes a display module having a display panel configured to display an image; a sound generating device on a rear surface of the display panel and including a first side and a second side perpendicular to the first side and an adhesive member in a partial region of the sound generating device, the adhesive member having a size smaller than one of the first side and the second side of the sound generating device.

A display apparatus includes a display module including a display panel configured to display an image and a first sound generating device on a rear surface of the display panel, the first sound generating device including a first vibration generating device and a second vibration generating device adjacent to the first vibration generating device, the first vibration generating device is configured to vibrate a center region of the first sound generating device based on a signal applied to the first sound generating device, and the second vibration generating device is configured to vibrate a periphery of the display panel based on the applied signal.

A display apparatus includes a display module displaying an image, a rear structure supporting the display module, a vibration generating device vibrating the display module, and a stiff member disposed on a rear surface of the display module. Accordingly, a sound pressure level corresponding to a high frequency domain is prevented from being reduced, thereby enhancing the quality of a sound output to a region in front of a display panel.

A display apparatus includes a display panel configured to display an image; a rear structure supporting the display panel and including a through hole in a thickness direction; a vibration generating device including at least one sound generating module in the through hole to vibrate the display panel; a vibration transfer member between the display panel and the vibration generating device, the vibration transfer member configured to transfer a vibration of the vibration generating device to the display panel; and a buffer member on one of the display panel and the rear structure.

A display device includes a display module displaying an image, a vibration generating device including at least one sound generating module vibrating the display module, a rear structure disposed on a rear surface of the display module to fix the vibration generating device, and a vibration transfer member disposed between the at least one sound generating module and the display module to extend from the at least one sound generating module to an edge of the display module. Accordingly, a sound pressure level corresponding to a high frequency domain is prevented from being reduced, thereby enhancing the quality of a sound output to a region in front of a display panel.
