Abstract
A display apparatus includes a display panel which displays an image and a vibration member attached to a surface of the display panel, where the vibration member receives a sound signal, generates a vibration in response to the sound signal, and transfers the vibration to the display panel to allow the display panel to output a sound.
Claims23
A display device comprising:
- a display panel which displays an image;
- a vibration control plate which includes a first surface contacting the display panel;
- a vibration member directly disposed on a second surface of the vibration control plate which is opposite to the first surface of the vibration control plate;
- a damper directly disposed on the second surface of the vibration control plate and spaced apart to the vibration member such that a contact portion of the damper and the vibration control plate is spaced apart from a side surface of the vibration control plate with a predetermined distance in a main plane extension direction of the vibration control plate;
- and
- a cover part covering the display panel, the vibration member and the damper,
- wherein the vibration member receives a sound signal, generates a vibration in response to the sound signal, and transfers the vibration to the display panel to allow the display panel to vibrate and to output a sound,
- wherein the damper includes a first contact surface and a second contact surface which respectively have planes parallel to the main plane extension direction of the vibration control plate and face each other in a first direction perpendicular to the main plane extension direction of the vibration control plate such that the first contact surface of the damper is coupled to the vibration control plate, and the second contact surface of the damper is coupled to a portion of the cover part which is parallel to the main plane extension direction of the vibration control plate and overlaps the vibration control plate in the first direction,
- the damper has a thickness between the first contact surface and the second contact surface in a first direction perpendicular to the main plane extension direction of the vibration control plate, and
- the thickness of the damper is greater than a thickness of the vibration member in the first direction.

A display device comprising:
- a display panel which displays an image;
- a cover part which disposed at a lower side of the display panel;
- a vibration control plate including a first surface attached to a surface of the display panel, and a second surface which is opposite to the first surface;
- a vibration member which includes a contact surface directly attached to the second surface of the vibration control plate;
- a damper which includes a first contact surface directly disposed on the second surface of the vibration control plate and a second contact surface coupled to the cover part, the first contact surface and the second contact surface respectively having planes parallel to a main plane extension direction of the vibration control plate and facing each other in a first direction perpendicular to the main plane extension direction of the vibration control plate;
- wherein the first contact surface of the damper is spaced apart from the contact surface of the vibration member with a predetermined distance in the main plane extension direction of the vibration control plate,
- wherein the cover part covers the display panel, the vibration member and the damper,
- wherein the vibration member receives a sound signal, generates a vibration in response to the sound signal, and transfers the vibration through the vibration control plate to the display panel to allow the display panel to vibrate and to output a sound, and
- wherein the second contact surface of the damper is coupled to a portion of the cover part which is parallel to the main plane extension direction of the vibration control plate and overlaps the vibration control plate in the first direction.
