A panel vibration type sound generating display device is disclosed. The display device includes a display panel for displaying an image; a sound generating actuator connected to the display panel and configured to vibrate the display panel to generate sound; a support structure spaced apart from the display panel with an air gap between the support structure and the display panel; and a baffle part disposed between the support structure and the display panel to surround the air gap.

Sound generating apparatus

A multi-panel organic light emitting display device is disclosed that includes a plurality of display panels coupled to each other. Each of the plurality of display panels includes: a substrate including an active area and a non-active area; and a display unit including an organic light emitting element on the substrate. Each of the plurality of display panels also includes: a plurality of signal lines disposed on the substrate and electrically connected to the display unit; and a plurality of link lines disposed under the substrate. Each of the plurality of display panels further includes a plurality of side lines connecting the plurality of signal lines and the plurality of link lines. Each of the plurality of display panels also includes a driving circuit electrically connected to the plurality of link lines.

Multi-panel organic light emitting display device

Embodiments of the present disclosure relate to an organic light emitting display device which directly vibrates an organic light emitting display panel to generate sound, and includes: an organic light emitting display panel including a light emitting layer including an organic light emitting material layer and an encapsulation layer disposed at one side of the light emitting layer; and a sound generating actuator in direct contact with the organic light emitting display panel to vibrate the organic light emitting display panel to generate sound. Especially, the organic light emitting display panel is a bottom emission type device, and thus can prevent generation of a weighted color mixing phenomenon in a wide viewing angle at the time of panel vibration and reduce the thickness or weight of the panel to thereby enhance the sound generation characteristic.

Organic light emitting display device including a sound generating apparatus

The present disclosure relates to a display device for generating sound by directly vibrating a display panel thereof, which includes a display panel connected to a surface of the display panel and configured to display an image; and a sound generating actuator, which is fixed to a support structure of the display panel and attached to the display panel to directly vibrate the display panel. In the display device, the progressing direction of the sound coincides with the image output direction in the display device. Therefore, sound localization or sound output characteristics of the display device or set apparatus can be improved, and a separate speaker is not required, the mechanism of the set apparatus can be easily designed, and a thickness thereof can be easily reduced.

An array substrate having a wiring of a pad region formed without an insulating film or without an insulating film and an organic film to reduce abnormal operations due to an increase in resistance caused by a contact margin at a high temperature, and a method for manufacturing the same are provided. The array substrate includes: an insulating substrate including a pad region and a thin film transistor (TFT) formation region; a first electrode layer formed in the pad region of the substrate; and a second electrode formed on the first electrode layer in an overlapping manner.

Array substrate with improved pad region

The present invention provides an organic light emitting display device that includes a display panel in which an organic light emitting diode and a driving circuit are disposed in each pixel area of a first pixel and a second pixel which are certain pixels among a plurality of pixels, a floating pattern insulated from at least one of a first electrode of the organic light emitting diode of the first pixel and a first electrode of the organic light emitting diode of the second pixel is formed in the display panel, or a connection pattern for electrically connecting the first electrode of the organic light emitting diode of the first pixel with the first electrode of the organic light emitting diode of the second pixel is formed.
