    Abstract: Disclosed are a method of modeling a haptic signal from a haptic object, a display apparatus, and a driving method thereof, which realize a tactile sense having a shape and texture of a haptic object. The method includes obtaining measurement data corresponding to a shape of a texture object while moving a sensor unit with respect to a haptic object including the texture object, obtaining force measurement data corresponding to a level of pressure applied to the haptic object, calculating shape modeling data and impulse modeling data corresponding to the texture object, based on the measurement data, calculating friction force modeling data corresponding to the texture object, based on the force measurement data, generating setting information of a haptic signal corresponding to the haptic object, based on the shape modeling data, the impulse modeling data, and the friction force modeling data, and storing the setting information of the haptic signal.

    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: 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.
