A head-mounted display according to an embodiment includes a left-eye optical system configured to guide display light for forming a left-eye display image to a left eye of a user, a right-eye optical system configured to guide display light for forming a right-eye display image to a right eye of the user, and a polarizing plate arranged between a left front space and a right front space, and the left front space is a space defined by the left-eye optical system, and the right front space is a space defined by the right-eye optical system.

An external scene image captured by an external scene imaging electronic camera attached to a head mounted display (HMD) is projected and displayed onto an image display screen arranged in front of the eyes of the user as a virtual image with a suitable viewing distance corresponding to the visual acuity of the user. At this time, for each object image presented in the virtual image of the external scene image, the virtual image is processed and formatted to add a predetermined degree of binocular disparity and image blur to the virtual image projected and displayed on the right and the left image display screen on the basis of a predetermined converted distance calculated from the real distance of each object. Thus, the user is given a sense of a realistic perspective for the virtual image of the external scene, free of the discomfort or unease.

Disclosed is a circuit board assembly, a display device, and a method for manufacturing the same. The display device includes a main board, a logic board, a X-coordinate circuit board and a display panel. The main board and the logic board forms a circuit board assembly with a stacked structure, and the logic board is connected to the X-coordinate circuit board by a flexible flat cable line.

A content sharing device for use in controlling content replicated from a video source device on a large common display screen, the content sharing device comprising a housing, a processor supported by the housing, at least first and second control buttons supported by the housing and linked to the processor, a cable linked to the processor and having a distal end opposite the processor, the cable including a connector at the distal end for linking to the video source device, wherein, the processor is programmed to enable content from the video source device linked to the connector to be replicated in a first field on the common display screen upon selection of the first control button and to enable content from the video source device linked to the connector to be replicated in a second field adjacent to and separate from the first field upon selection of the second control button.

A content sharing device for use in controlling content replicated from a video source device on a large common display screen, the content sharing device comprising a housing, a processor supported by the housing, at least first and second control buttons supported by the housing and linked to the processor, a cable linked to the processor and having a distal end opposite the processor, the cable including a connector at the distal end for linking to the video source device, wherein, the processor is programmed to enable content from the video source device linked to the connector to be replicated in a first field on the common display screen upon selection of the first control button and to enable content from the video source device linked to the connector to be replicated in a second field adjacent to and separate from the first field upon selection of the second control button.

A conferencing assembly for sharing content from source devices includes a common display screen, a switcher controlling input to the screen, and a table assembly with a tabletop opening. A control cable assembly has a first end linked to the switcher, a second ends having a plug connectable to a source device communication port, and a first control cable located therebetween. A take up assembly including a first weight is disposed below the opening. The control cable assembly links to the first weight to apply a force tending to pull the second end of the control cable assembly toward the opening. A first user interface including a control button useable to send a signal to the switcher causing it to provide first content from a source device connected to the control cable assembly to the screen is integrated into the table assembly and is associated with the control cable assembly.

Disclosed is a method of controlling a horizontal screen or a vertical screen of a television. The method includes the following operations of: acquiring a mode of a television, and judging whether the mode is a mobile phone mode; in response that the television is in the mobile phone mode, acquiring an image to be displayed, and playing the image in the vertical screen according to a vertical state of the image. The disclosure further discloses a device of controlling a horizontal screen or a vertical screens of a television, and a computer readable storage medium.

Provided are a boundary display control device, a boundary display control method, and a program which can reduce an oppressive feeling of a user when a virtual object representing a boundary surface dividing a region in a real space in which the user is permitted to exist from a region in the real space in which the user is not permitted to exist is displayed. A program executing section (84) locates a position of the user wearing a head-mounted display. An approach portion identifying section (86) identifies, as an approach portion, a part of a boundary surface dividing a permitted region that is the region in the real space in which the user is permitted to exist from an unpermitted region that is the region in the real space in which the user is not permitted to exist, on the basis of the located position of the user. A display control section (92) causes the head-mounted display to display a virtual object representing the identified approach portion.

A display apparatus including display panel, a rear case to cover a rear of the display panel and the rear case including a cable fixing hole to which a cable is fixed, a connector connected to the cable and fastened to the rear case so that the cable is connected to the rear case, a cable holder to surround a part of the cable and fixed to the cable fixing hole so that the cable is fixed to the rear case, and a clamp to fix the cable holder to the cable fixing hole, wherein the clamp includes a first hook to be fixed to the cable fixing hole, and a second hook having a different shape than a shape of the first hook and to be fixed to the cable fixing hole to have a greater fixing force than a fixing force of the first hook.
