Abstract: 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.

Abstract: The present disclosure relates to a display device including an optical device, more specifically, it relates to a display device in which the optical device is positioned under the display panel so that the optical device is not exposed in the front direction. Even if the optical device is located under the display panel, the display device can normally perform the function of the optical device related to the front direction of the display panel and have a structure for this.

Abstract: 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.

Abstract: Disclosed is an organic light emitting display device including an encapsulation layer covering a pixel array layer provided on a substrate and a cover window coupled to a touch sensing layer. The touch sensing layer may include a first touch electrode layer provided on the encapsulation layer, a second touch electrode layer provided on the first touch electrode layer, and a pressure reaction member provided between the first touch electrode layer and the second touch electrode layer. Electrical characteristic of the pressure reaction member may be changed according to force applied to the pressure reaction member.

Abstract: An electronic device has a force touch function. The electronic device includes an image display module having a touch electrode. A cover window attaches to a front surface of the image display module. A housing receives the image display module therein, and supports the cover window. A panel moving part is between the housing and the image display module. A driving circuit senses a touch force based on a distance between the image display module and the housing which are spaced from each other with the panel moving part interposed in-between.
