A flexible display device may include a display module unit configured to project an image, a frame, and a connecting unit. The frame supports the display module unit. The connecting unit is coupled to the display module unit and the frame, and is adjustable so as to allow an amount of curvature of the display module unit to be adjusted.

Provided are a head-mounted display and an image display device. The HMD includes a first ball joint, a second ball joint and an arm member. The first ball joint is provided with a first rod portion and a first sphere portion. The second ball joint is provided with a second rod portion and a second sphere portion. The first rod portion passes through a first hole portion. The second rod portion passes through a second hole portion. A position of a half mirror in a first position of a display casing when the first rod portion is positioned at the center of the first hole portion and the second rod portion is positioned at the center of the second hole portion is farther from the mounting member than a position of the half mirror in a second position of the display casing.

A rollable display device includes a rollable display and a first protection film disposed on a first surface of the rollable display. The first protection film extends beyond a first display edge of the rollable display. The rollable display device further includes a second protection film disposed on a second surface of the rollable display facing the first surface of the rollable display. The second protection film extends beyond the first display edge of the rollable display. The rollable display device additionally includes a first adhesive layer disposed between the rollable display and the first protection film. The rollable display device further includes second adhesive layer disposed between the rollable display and the second protection film, and a first adhesion part disposed adjacent to the first display edge of the rollable display and between the first protection film and the second protection film.

Disclosed is a rollable and hidden laser television integrated machine. An electric panel opening mechanism, a screen lifting mechanism, a screen rolling and collecting mechanism, and a laser projection display device are arranged inside a television integrated machine main body. The screen lifting mechanism is movably arranged in a lifting groove. The top end of the screen is connected to the screen lifting mechanism, and the bottom end of the screen is connected to the screen rolling and collecting mechanism. A projection groove is formed at the middle position of the upper surface of the television integrated machine main body, and the top end of the electric panel opening mechanism is movably arranged in the projection groove. The laser projection display device is arranged under the electric panel opening mechanism. The middle portion of the box body is provided with a sound transmission mesh plate.

An object is to provide a head-mounted display apparatus that makes it possible to accurately determine a mounting deviation. The technology provides a head-mounted display apparatus including a sensor that detects a change in position of the head-mounted display apparatus relative to a head. The technology further provides an image display system including the head-mounted display apparatus and an information processor that sends image data to the head-mounted display apparatus. The technology further provides an image display method including a detection step of detecting the change in position of the head-mounted display apparatus relative to the head, and an adjustment step of adjusting a position to which the head-mounted display apparatus projects image display light on the basis of the change in position detected in the detection step.

A cover opening and closing device is a cover opening and closing device for shielding an object, the cover opening and closing device including a cover attractable to or repellable by a magnet, a guide accommodating the cover, and a housing covering the guide. The cover is accommodated in a space between the guide and the housing. The guide allows the cover to be moved, by the magnet outside the space, between a first position where the cover shields the object and a second position where the cover does not shield the object.

Provided is a display device or a display system capable of displaying images along a curved surface, a display device or a display system capable of displaying images seamlessly in the form of a ring, or a display device or a display system that is suitable for increasing in size. The display device includes a display panel. The display panel includes a first part and a second part and is flexible. The first part can display images. The second part can transmit visible light. The display panel is curved so that the second part and the first part overlap with each other.

An image display device is a self-luminous type device including a light emitting portion, and a casing portion of a display device unit has a heat dissipating structure portion through which a part of the image display device is exposed for heat dissipation. In manufacturing the display device unit, when performing simple and reliable assembly while securing a high heat dissipation characteristic, for example, by using characteristics of a silicon substrate, high accurate positioning is performed in a display device positioning portion.
