A display apparatus and a computing apparatus including the same are provided. A display apparatus includes: a display module including a display panel configured to display an image, a system rear cover covering a rear surface of the display module, a vibration plate between the system rear cover and the rear surface of the display module, and a vibration module configured to vibrate the vibration plate, wherein the display panel is further configured to vibrate based on a vibration of the vibration plate to output sound.

In order to provide an optical element in which the occurrence of a region where no light beams are present (omission) is prevented, an optical element is provided with a main substrate which is manufactured from a light-transmitting material and in which a front surface and a rear surface are parallel to the setting directions, wherein at least one main beam splitter surface is provided obliquely to the setting directions and formed inside the primary substrate. The optical element is also provided with a sub substrate which is manufactured from a light transmitting material and in which a front surface and a rear surface are parallel to the setting directions, wherein a sub beam splitter surface is arranged at least between the front surface or the rear surface of the single sub substrate, and the rear surface or the front surface of the main substrate.

Disclosed is a display device that includes a display panel, sound generating actuators including a first sound generating actuator in a first area of the display panel and a second sound generating actuator in a second area of the display panel, the first and second sound generating actuators configured to vibrate the display panel to generate sound, and a partition between the first sound generating actuator and the second sound generating actuator.

A holding tool is capable of performing positioning and reliable attachment by simple insertion operation when attaching a wearable device, and is capable of performing reliable detachment by simple operation when the device is detached. When a body part of a wearable device is inserted into a holding frame body, a projected engagement part of an elastic pressing body provided in the holding frame body is engaged with an upper surface and/or a lower surface of the body part. Engagement between the upper surface and/or the lower surface of the body part and the projected engagement part of the elastic pressing body is released by operating an operation part of the elastic pressing body upward and/or downward, to allow the wearable device to be pulled out of the holding frame body.

A set-top box device capable of providing electrical power to an antenna includes an insulation housing, a printed circuit board, a metal portion, and a conductive locking member. The insulation housing has at least one lateral arranged thereon a through hole portion. The printed circuit board is arranged in the insulation housing and includes a power supply module. The metal portion is arranged on the printed circuit board and includes a locking hole corresponding the through hole portion. The conductive locking member passes through the locking hole, the through hole portion, a conductive end portion of the power supply line, and the metal portion. The power supply module feeds a current into the antenna through a connection of the metal portion, the conductive locking member, and the conductive end portion, and the current flows to a ground portion of the signal line thereby forming a power supply loop.

A display device is disclosed. The display device of this invention includes: a display panel; a plate whose one side is attached to the rear surface of the display panel; a module cover including a forming area that is projected and recessed in at least some part to keep a distance from the plate; and a housing attached to the module cover. According to the present invention, it is possible to minimize heat transfer towards the display panel by including a module cover where a forming area is provided to keep a distance from a plate.

There is provided a head-mounted display device capable of adjusting a distance to an image forming position that includes video display elements that show a video, optical elements arranged in front of user's eyes to cause the video shown by the video display elements to be incident on the user's eyes, and a control mechanism that changes an optical distance between the video display elements and the optical elements. Also provided is a video display system that includes the head-mounted display device and a video supply device that includes a video supply section that supplies a video to the head-mounted display device and an image forming distance control section that outputs a control instruction to change a distance from the optical elements to the image forming position by operating the control mechanism.

Methods and apparatus provide for controlling an information processing apparatus that is connected to an image display apparatus worn on a head of a user, including: producing a planar image representing virtual objects in a virtual world, wherein the planar image includes characteristics that require the image display apparatus to be a non-see-through image display apparatus that does not allow the user to visually recognize real world objects outside the virtual world; and displaying the planar image on the image display apparatus in a display mode that changes a shape of the planar image as a function of a change in position and/or orientation of the image display apparatus, wherein the change in the shape of the planar image includes presenting the planar image in an orientation other than a front direction of the user.
