    Abstract: A display device that includes a display panel having a first substrate, a second substrate, and a light-emitting element layer. The light emitting layer is disposed between the first and second substrates and is configured to emit light in a direction toward the second substrate. A first sound generator is disposed on a first surface of the first substrate and is configured to vibrate the display panel to output a first sound. A first heat dissipation film is disposed between the first substrate and the first sound generator.

    Abstract: A display device includes a display panel in which first holes arranged in a first direction and a second direction that intersects the first direction are defined, and a first panel bottom member which is disposed on one surface of the display panel and in which second holes arranged in the first and second directions are defined. A maximum length of a second hole among the second holes in the first direction satisfies “e×(a+c)” where a denotes a maximum length of a first hole among the first holes in the first direction, c denotes a minimum distance between neighboring first holes among the first holes in the first direction, and e is a positive integer.

    Abstract: A tiled display comprises display devices adjacent to one another and each comprising first pixels and second pixels, a first boundary area where longer sides of at least two of the display devices are adjacent to each other, and a second boundary area where shorter sides of at least two of the display devices are adjacent to each other. Each of the first pixels and the second pixels comprises sub-pixels. The first pixels are disposed in the first boundary area such that the sub-pixels of the first pixels are parallel to the longer sides of the display devices. The second pixels are disposed in the second boundary area such that the sub-pixels of the second pixels are parallel to the shorter sides of the display devices.

    Abstract: A display device includes a display panel including a display layer including light-emitting elements disposed on a substrate, and a sensor electrode layer disposed on the display layer. The sensor electrode layer includes a first sound electrode and a second sound electrode; a vibration layer electrically contacting the first sound electrode and the second sound electrode and being deformed in response to a first sound driving voltage applied to the first sound electrode and a second sound driving voltage applied to the second sound electrode; and sensor electrodes disposed on the vibration layer. The sensor electrodes sense an input.
