An information display device attachable to a structure includes a display panel and a surface member. The display panel has a display surface and displays information on the display surface. The surface member is a surface member disposed on the display surface side of the display panel, and has a surface area larger than that of the display panel. When the display panel is turned on, only the information displayed on the display surface of the display panel becomes visible through the surface member.

A vehicle includes a vehicle door and a diaphragm. The vehicle door includes an inner door panel and an outer door panel that define a door cavity therebetween. The diaphragm is disposed within the door cavity and is attached to an inner surface of the outer door panel. The diaphragm cooperates with the inner surface of the outer door panel to define a diaphragm cavity.

An information display device attachable to a structure includes a display panel and a surface member. The display panel has a display surface and displays information on the display surface. The surface member is a surface member disposed on the display surface side of the display panel, and has a surface area larger than that of the display panel. When the display panel is turned on, only the information displayed on the display surface of the display panel becomes visible through the surface member.

An information display device (1G) attachable to a structure includes a display panel (23) and a surface member (11). The display panel (23) has a display surface and displays information on the display surface. The surface member (11) is disposed on the display surface side of the display panel (23) and is in a state where only the information displayed on the display surface of the display panel (23) is visible through the surface member (11) when the display panel (23) is turned on. The surface member includes a first layer (71) disposed on a front side, and a second layer (72) that is disposed on the display panel (23) side with respect to the first layer (71) and adjusts light transmittance of the surface member (11).

An information display device attachable to a structure includes a plate-like body, a display panel, and a surface member. The plate-like body is a part of the structure and has a first attaching surface, a second attaching surface opposite to the first attaching surface, and a side portion that connects the first attaching surface and the second attaching surface to each other. The display panel is attached to the plate-like body and displays information on the display surface. The display surface is disposed from the first attaching surface to the second attaching surface of the plate-like body. The surface member is disposed on the display surface side of the display panel to cover the display panel and is in a state where only the information displayed on the display surface of the display panel is visible through the surface member when the display panel is turned on.

A display device includes a window and a display panel coupled to a bottom surface of the window. The display panel has a substantially regular tetragonal shape or a substantially rectangular shape in a plan view, and the window includes a base member and a bezel layer on a bottom surface of the base member. Between one and three light-transmissive main alignment marks and a transmission area having a different shape than that of the display panel are defined in the bezel layer, and each of the main alignment marks is arranged at a position corresponding to a vertex of the display panel or at a position corresponding to a vertex of an imaginary regular tetragon or of an imaginary rectangle that has the same center point as the display panel and that is larger than the display panel.

A pocket is structured to be removably securable to a vehicle door. In one arrangement, the pocket includes at least one positioning element receiving cavity structured to extend horizontally or substantially horizontally when the pocket is attached to a vehicle door.

A vehicle display device includes a first display unit disposed in a first portion of a vehicle and including a first display panel to display a first image and a first power supply to supply a first power supply voltage to the first display panel, the first power supply configured to detect an abnormality of a signal output to the first display panel to generate a first shut-down control signal; a second display unit disposed in a second portion of the vehicle and including a second display panel to display a second image and a second power supply to supply a second power supply voltage to the second display panel, the second power supply configured to detect an abnormality of a signal output to the second display panel to generate a second shut-down control signal; a third display unit disposed in a third portion of the vehicle and configured to display a third image or at least one of the first and second images; and a controller to receive first image data corresponding to the first image, second image data corresponding to the second image, and third image data corresponding to the third image to provide the received first image data, the received second image data, and the received third image data to the first display unit, the second display unit, and the third display unit, respectively. The controller is configured to supply the first image data to the third display unit in response to the first shut-down control signal, and to supply the second image data to the third display unit in response to the second shut-down control signal.

A switch device includes an operation switch including a switch knob formed integrally with a recess configured to allow a finger to be inserted. The operation switch includes a detector configured to detect a change in a physical amount caused by operation of the switch knob.

A frame for a display device extends in a main plane. The frame includes a plurality of segments coupled to one another, including at least a first segment having at least one injection orifice allowing the injection of an optical adhesive. The plurality of segments defines an opening therebetween delimited by a plurality of inner edges facing each segment, including at least a first inner edge of the first segment. The first segment includes an injection channel having a first end and a second end. The first end is fluidly connected to the injection orifice, and the second end forms the first inner edge of the first segment.
