Abstract: A display apparatus includes a display panel configured to display a first image in a first direction and configured to display a second image in a second, different direction, a sound output unit including sound output modules to output a sound, and a sound focusing unit. The sound focusing unit is configured to receive first and second audio signals synchronized with video data signals of the first image and the second image, apply a direction focusing weight to the first and second audio signals, and to provide the sound output modules with a sound signal having the direction focusing weight applied thereto. Furthermore, the sound output unit is configured to receive the sound signal corresponding to the sound output modules, to output a first sound corresponding to the first image in the first direction, and to output a second sound corresponding to the second image in the second direction.

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: An ultrasonic sensor and a display device and may drive a plurality of sensing pixels disposed in the ultrasonic sensor simultaneously to transmit an ultrasonic wave, may make a first electrode disposed in a sensing pixel to be floated at a timing receiving a reflected signal to store the signal, and then may perform a sensing sequentially. Therefore, as an accurate sensing may be possible while reducing a duration and a number of an ultrasonic wave transmitting, a sensitivity and an accuracy of a sensing may be maintained while improving a driving efficiency of the ultrasonic sensor.
