A sound apparatus may include a vibration member, a housing configured to cover a rear surface of the vibration member, and a vibration apparatus including one or more vibration devices configured to vibrate the vibration member. The vibration member may include a non-planar structure.

Sound apparatus and sound system including the same

A vibration apparatus can include a first cover member; a second cover member; a vibration portion between the first cover member and the second cover member; a contact portion between the first cover member and the vibration portion; and a signal cable. The signal cable can include a first signal line connected to a first surface of the vibration portion via the contact portion, and a second signal line connected to a second surface of the vibration portion opposite to the first surface of the vibration portion.

Vibration apparatus and apparatus including the same

An apparatus can include a display member configured to display an image, a vibration apparatus disposed at a rear surface of the display member, a supporting frame disposed at a rear surface of the vibration apparatus, and an adhesive member disposed between the supporting frame and the rear surface of the display member. In addition, the adhesive member and/or supporting frame is spaced apart from the vibration apparatus, and the vibration apparatus is configured to vibrate in a direction toward the display member.

Apparatus

A display apparatus is provided, and the display apparatus includes a display member having a plurality of pixels configured to display an image, and a vibration apparatus configured to vibrate the display member based on a haptic driving signal. The haptic driving signal includes a texture signal and an ultrasonic signal. Accordingly, the display apparatus can provide a user with a tactile feedback including a virtual texture.

Display apparatus

A disclosed vibration device comprises a first vibration generator and a first connection member disposed on a first surface of the first vibration generator. The first vibration generator may comprise a first vibration part including a plurality of inorganic material portions having a piezoelectric characteristic and an organic material portion between the plurality of inorganic material portions.

Vibration device and apparatus including the same

A vibration apparatus may include a vibration device and an adhesive member at a surface of the vibration device. A modulus of the vibration device may be equal to a modulus of the adhesive member or may be greater than the modulus of the adhesive member.

Vibration apparatus and apparatus and vehicular apparatus comprising the same

A vibration device can include a vibration portion; a first electrode portion disposed on a first surface of the vibration portion; and a second electrode portion disposed on a second surface of the vibration portion, in which each of the first and second electrode portions include at least one of a conductive metal particle and a carbon particle.

Discussed is an apparatus including a display panel configured to display an image, a vibration apparatus disposed at a rear surface of the display panel to vibrate the display panel and to generate sound via the display panel, and an adhesive member and a connection member between the display panel and the vibration apparatus.

Provided is a method of manufacturing new liquid crystal display device according to an embodiment of the present invention. Firstly, an alignment film is formed on a substrate. The alignment film is divided into a first alignment film formed using, as a precursor, liquid-state polyimide that contains a photodecomposition substance and a second alignment film formed using, as a precursor, a polyamic acid that does not contain a photodecomposition substance. UV light is irradiated to the alignment film, and decomposed substances formed by irradiation of the UV light is removed by an at least two-step removing process. By the method of manufacturing a liquid crystal display device according to the exemplary embodiment of the present disclosure, bright spots are minimized in pixels and a brightness of black is lowered, so that a liquid crystal display device with a high contrast ratio can be realized.

Liquid crystal display device and method of manufacturing the same

An alignment film for liquid crystal display device includes a first portion positioned towards to the liquid crystal layer and a second portion positioned away from the liquid crystal layer. The first portion provides improved anchoring force while the second portion exhibits a lower volume resistance than the first portion. Thus, AC image sticking and DC image sticking can be minimized at the same time.

A fringe field switching (FFS) liquid crystal display (LCD) device which uses an organic insulating layer and consumes less power, in which film quality of an upper layer of a low temperature protective film is changed to improve undercut within a pad portion contact hole, and a method for fabricating the same is provided.
