The present disclosure provides a rollable display device including a display panel configured to display an image, a panel roller having a mechanical structure that enables rolling up the display panel around an outer circumferential surface of the panel roller, and a roller driving unit configured to control a motor so that the display panel rolls around the outer circumferential surface of the panel roller or unrolls therefrom, wherein the roller driving unit and the motor are disposed in the panel roller.

A head-mounted display includes a playback processor which plays back a moving image from first time until second time, a box for placing a container containing a perfume inside, a filled section which is temporarily filled with the perfume and emits the temporarily filled perfume according to starting playback of the moving image, and a tubular vent hole which is in contact with a nose of a user when the user wears the head-mounted display.

To provide a display device that gives a viewer a strong stereoscopic effect or sense of depth in a two-dimensional image and a display device that gives a viewer a natural stereoscopic effect or sense of depth in a two-dimensional image, a display device including a frame portion and a display portion which has a display surface on a frame portion side and is located so as to be apart from the frame portion with a distance therebetween, in which the display portion overlaps with an opening of the frame portion, and an end portion of the display portion overlaps with the frame portion, is provided. In addition, a structure in which a corner of an inner frame of the frame portion has curvature or a structure in which the size of the inner frame of the frame portion is variable is added to the display device.

An image generating section reads image data from an image storing section to generate an original image in keeping with the attitude of a head-mounted display. A lens distortion correcting section generates a primary image by correcting beforehand the original image in a manner canceling out the distortion thereof that appears when viewed through lenses of the head-mounted display. A different image embedding section generates an embedded image by embedding a different image into an unused area of a rectangular format for transmitting the primary image. An HDMI transmitting section transfers the embedded image to the head-mounted display.

Provided is an image display device used by being mounted to a head or a face of a user, including a first display unit that displays an internal image seen from a side of the user, a second display unit that displays an external image seen from outside the image display device, and a control unit that controls display of the internal image and the external image.

An image display device comprises: a flexible display unit configured to be bent, by an external force, in a first state and a second state where the flexible display unit has different radiuses of curvature; and a middle cabinet assembly configured to cover side surfaces of the flexible display unit, wherein the middle cabinet assembly comprises: a first middle cabinet coupled to the flexible display unit, and disposed to cover a first side of the flexible display unit; and a second middle cabinet disposed to cover a second side of the flexible display unit, the second side perpendicular to the first side, and the second middle cabinet configured to perform a relative motion with respect to the first middle cabinet when the flexible display unit is transformed between the first state and the second state.

An object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation. Another object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation on the basis of ergonomics. The I/O device includes a display device that can generate a stereoscopic image, a depth level sensor that measures a distance to an object, and a control unit that performs display on the display device in accordance with the depth level sensor. A detection region of the depth level sensor has a width in the depth level direction of the depth level sensor, and is composed of a curved measurement region, such that the radius of curvature on the far side in the depth level direction of the depth level sensor is different from the radius of curvature on the near side in the depth level direction of the depth level sensor.

An arrangement for fastening a first element, such as a television, and a second element, such as a decorative element to a wall, includes a base structure, which includes four connectable members configured for forming a braced base structure, when base structure is fastened to the wall with fastening elements from at least four fastening points. Further, the arrangement includes at least one first fastening member mounting the first element to the base structure and at least one second fastening member, which first and second fastening members are configured for fastening to the first and the second elements, respectively, and moving elements for moving the second fastening member between a first position and a second position, which moving elements are configured for connecting to the second fastening member in order to mount the second element to the base structure optionally via base members.
