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.

Display device

A display apparatus includes a display module including a display panel configured to display an image and a sound generating module on a rear surface of the display panel, the sound generating module includes a vibration generating device, a circuit board on a lower surface of the vibration generating device, a first adhesive member between the circuit board and the vibration generating device, and a second adhesive member between the vibration generating device and the display panel, an elastic modulus of the second adhesive member differing from an elastic modulus of the first adhesive member.

Display apparatus

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.

Ultrasonic sensor and display device

An electronic apparatus comprises a display module configured to display an image and including a touch electrode layer, a vibration generator including a vibration element on a rear surface of the display module, a touch driver configured to generate touch data by sensing a touch through the touch electrode layer, the touch data including noise information, an audio processor configured to supply an audio signal to the vibration element, and a controller configured to control a driving frequency of the audio signal based on the touch data.

Electronic apparatus

A touch display device comprises a display panel including a plurality of light-emitting diodes respectively including an anode electrode and a cathode electrode; a touch sensor disposed at a first area of the display panel; a light-emitting element disposed on the cathode electrode at a second area of the display panel; and a light-receiving sensor disposed on a rear surface of the display panel.

Touch display device and fabrication method thereof

A display apparatus includes a display module including a display panel configured to display an image and a first sound generating device on a rear surface of the display panel, the first sound generating device including a first vibration generating device and a second vibration generating device adjacent to the first vibration generating device, the first vibration generating device is configured to vibrate a center region of the first sound generating device based on a signal applied to the first sound generating device, and the second vibration generating device is configured to vibrate a periphery of the display panel based on the applied signal.

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.

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.

Display apparatus with multi-direction sound generation

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 includes a first touch electrode layer provided on the encapsulation layer, a second touch electrode layer provided on the first touch electrode layer, and a thickness modification member between the first touch electrode layer and the second touch electrode layer.

Organic light emitting display device

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.
