The present invention provides an optical scanning control device and a retina scanning projection device provided with a structure for suppressing heat transfer to a laser module, and a heat dissipation structure for dissipating the heat of the laser module. The optical scanning control device (10) is configured to emit, as image light, a laser light in accordance with an image signal. The optical scanning control device includes: a housing (11) made of metal; a laser module (125) configured to emit laser light, which abuts the top of the base (11a) of the housing, and is arranged on one side inside the housing; a power supply unit (16) arranged inside the housing on a side opposite that of the laser module; and an electronic circuit board (12) having heat source members (IC chips 14) configured to cause the laser module to emit image light, the electronic circuit board being arranged on a side opposite the base-side of the laser module. The heat source members are arranged on a surface on a side of the electronic circuit board facing away from the laser module, and are at positions which avoid a position directly above the laser module.

There is provided an image processing device, an image processing method, and an image system capable of reducing discomfort of a user, such as “VR sickness.” The image processing device includes: an image generation unit configured to generate an avatar viewpoint image according to a viewpoint of an avatar corresponding to a user in a virtual world as a first presentation image to be presented to the user, and generate a second presentation image different from the avatar viewpoint image in a case in which posture difference occurs between an actual posture of the user based on a result of detecting motion of the user and a posture of the avatar. The present technique is applicable, for example, to an image processing device etc. for generating an image to be displayed on a head mounted display.

An image display device includes: a display panel which displays an image on a front surface of the display panel; a heat diffusing plate on a rear side of the display panel; and a frame along an edge surface of the display panel and an edge surface of the heat diffusing plate. The frame includes: a side wall which is disposed opposite to the edge surface of the display panel and the edge surface of the heat diffusing plate; and a support wall which projects from the side wall toward the heat diffusing plate. The heat diffusing plate includes a peripheral portion between the support wall and the display panel. The peripheral portion includes, on a rear side, a stepped portion which houses at least part of support wall.

A display device is provided and includes a display panel; and a wiring board comprising a flexible base, a terminal electrically connected to the display panel, wherein the flexible base including a first surface, a second surface on an opposite side to the first surface, and a concavity in the second surface, the wiring board is mounted on the display panel and is bent so that the wiring board is opposed to a rear surface side of the display panel, and the concavity is provided in the portion of the wiring board which is bent.

This display device comprises: a display panel; a module cover positioned on the rear surface of the display panel; an adhesive member coupling the module cover and the display panel; a substrate plate covering a first region on the rear surface of the module cover; and a control unit coupled to the rear surface of the substrate plate and controlling the display panel, wherein the substrate plate includes a contacting part that is in contact with the module cover, and a spacing part that is spaced apart from the module cover and forms an air gap between the substrate plate and the module cover. The thickness of the module panel and the number of components can be reduced, such that the manufacturing cost of the display device and the weight of the product can be reduced.

A display device according embodiment of the present disclosure may include a display main body, an image capturing unit which slides between a first position accommodated inside the display main body and a second position protruding outside the display main body, a guide body provided inside the display main body and slidingly guiding the image capturing unit, and a torsion spring connecting the image capturing unit and the guide body to apply an elastic force to the image capturing unit. The direction of the elastic force applied to the image capturing unit by the torsion spring may change when the image capturing unit passes through a third position located between the first position and the second position.

A speaker device includes: a speaker unit configured to output a sound; a speaker box covering at least a part of a back surface of the speaker unit; and a duct comprising a first opening that is open within the speaker box, and a second opening opposite the first opening, the duct communicating together an interior and exterior of the speaker box via the first and second openings, wherein the duct further comprises a third opening disposed in a midway location between the first and second openings.

Disclosed herein is a smart wall including a frame structure including a mounting cell, an electronic appliance disposed in the mounting cell, a first moving art wall positioned in front of the mounting cell and configured to move in a thickness direction, a second moving art wall positioned in front of the mounting cell and configured to move in a vertical direction, a horizontal driver configured to drive the first moving art wall, and a vertical driver configured to drive the second moving art wall. The smart wall may be equipped with multimedia devices, such as a display device and an audio devices, and household appliances, such as an air cleaner and a humidifier, on a wall, thereby minimizing the exposure of the home appliances.

A movable display device includes a carrying module, a lifting module, a frame module and a display module. The carrying module includes a carrier unit, a base unit disposed on the carrier unit, and a plurality of positioning units disposed on the carrier unit. The lifting module is disposed on the base unit. The frame module includes a primary frame unit movably connected to the positioning units and a plurality of secondary frame units movably connected to the primary frame unit. The primary frame unit has a connecting portion connected to the lifting module. The secondary frame units are respectively located at two sides of the primary frame unit. The display module includes a primary display unit disposed on the primary frame unit and a plurality of secondary display units respectively disposed on the secondary frame units.

A screw attachment member includes a structure in which an insertion hole through which a screw passes and an opening are formed. In the structure, a peripheral edge portion of the insertion hole is in contact with a bearing surface of a head portion of the screw. The insertion hole is formed so that a distance between an inner peripheral surface and a central axis of the insertion hole varies in a circumferential direction. The opening is formed in a periphery of a proximal portion in the insertion hole at which a distance between the inner peripheral surface and the central axis is shorter than an average.
