An optical detecting device includes a receiving box and a telescopic arm. The receiving box includes an electrical connection port and a first conductive portion electrically connected to the electrical connection port. The telescopic arm is slidably disposed in the receiving box and includes an optical sensor and a second conductive portion electrically connected to the optical sensor. When the telescopic arm and the receiving box are in different sensing positions, the first conductive portion is electrically connected to the second conductive portion.

A display apparatus including a sealing member having an improved structure, the display apparatus includes a housing including an opening, a display module including a display panel, the display module arranged inside the housing for the image to be displayed through the opening, a housing cover coupled to the housing to cover the opening while covering a rear surface of the display module, and a sealing member provided to seal a gap between the housing and the housing cover, the sealing member including a contact surface convexly formed toward the housing cover and a first protrusion and a second protrusion arranged on the contact surface, wherein at least a portion of the contact surface located between the first protrusion and the second protrusion is located at a same level as the first protrusion and the second protrusion or protrudes outward of the first protrusion and the second protrusion.

Provided are a levitating display device and an operating method thereof. The display device includes a frame unit and a panel unit, wherein the frame unit includes a power receiver and a wireless power transmitter configured to wirelessly transmit power received by the power receiver to the panel unit, and the panel unit includes a wireless power receiver configured to wirelessly receive the power from the wireless power transmitter and a display configured to receive the power from the wireless power receiver and display an image.

A video display control apparatus receives a video content generated by a control target device in accordance with a control operation of a user via a network and displays the received video content on a head mount display attached to the user. The video display control apparatus includes a detection unit that detects a change in a direction of face or line of sight related to the control operation and a first display control unit that generates an auxiliary pattern in which at least one of a display position and a display form changes so as to follow the detected change in the direction of the face or the line of sight related to the control operation, superimposes the auxiliary pattern on the video content, and displays the video content on the head mount display.

Disclosed herein is a first-person view (FPV) headset comprising a shell and a fan plate coupled to the shell, wherein the fan plate comprises an attachment point configured to receive a headset accessory. The attachment point may comprise a hinge mount and/or a quick-release connector (e.g., comprising a pin, a screw, a button, a magnet). The attachment point may include an electrical connector for power and/or data. Also disclosed are accessories (e.g., an antenna, an antenna mount, a digital video receiver) with physical features that are complementary to the attachment point, thereby enabling them to be attached to the FPV headset.

The present invention provides devices for presenting entertainment by obtaining from a selected artist video and audio data regarding the artist's work and placing the data on a portable storage device for use in an entertainment device. After uploading the data into the entertainment frame's controller, the user selects one or more presentations by the artist to be played on the entertainment device. The entertainment device comprises a picture frame being mounted on a vertical surface with a display screen in the picture frame. The frame has a rechargeable battery for operating a controller that accepts an input device with a selected artist's video and audio data. The audio and video are played on the screen to provide entertainment from a singer or painter. Further, the entertainment device may be modular and removable from the picture frame so as to be transported easily to other locations, or the input device may be an flash album device.
