摘要:
Disclosed in the invention are a device for deploying and retracting liquid crystal display (LCD) and Control Method Thereof, including shafts connected to the LCD (1) and a servomechanism which drives the LCD on the shafts to deploy and retract. Wherein, the said servomechanism comprises a gear motor, a one-way bearing dynamically connected to the gear motor, an electromagnetic clutch, a speed reducer, and a plane four-bar linkage mechanism which drives the LCD on the said shafts to rotate. The said electromagnetic clutch is also connected to a spring motor which dynamically connects to the speed reducer. In the deploying and retracing direction of the said LCD, a stowed position transducer and a retracted position transducer are disposed to monitor the LCD position changes and an angle sensor to monitor the LCD deploying speed changes. The said stowed position transducer, retracted position transducer, and angle sensor are electrically connected to a controller. The controller collects and processes signals generated by the stowed position transducer, retracted position transducer, and angle sensor and controls LCD retracting in the event of power outage or unexpected exceptions.

According to one embodiment, a television receiver (1) includes: a display device (6); a casing (2); a substrate (10); a supporting portion (15); a first engaging portion (18); and a second engaging portion (15n). The substrate (10) is located between the display device (6) and a wall of the casing (2). The supporting portion (15) supports the substrate (10), and is fixed to the wall in a state in which the supporting portion (15) is in contact with a surface of the display device (6) or in a state in which the supporting portion (15) is capable of being in contact with the surface if the wall moves toward the display device (6) side. The first engaging portion (18) is provided to the wall. The second engaging portion (15n) is provided to the supporting portion (15), and engages with the first engaging portion (18) in a direction along the surface.

A wall mount (100) for a display apparatus to vertically move an apparatus body (10) of the display apparatus in an electromotive manner and a display apparatus having the same are provided. A wire (120) is mounted at the rear of the apparatus body. The wall mount (100) includes a plurality of wire hanging members (110a,110b) fixed to a rear of the apparatus; a wire (120) connected between the wire hanging members (110a,110b); a guide member (130) which is configured to move vertically while supporting the wire, to thereby move the apparatus vertically, the guide member (130) not being exposed when the apparatus is viewed from a front of the apparatus; and a base member (150) which is configured to be fixed to the wall to vertically move the guide member in an electromotive manner.

System and method for control using face detection or hand gesture detection algorithms in a captured image. Based on the existence of a detected human face or a hand gesture in an image captured by a digital camera, a control signal is generated and provided to a device. The control may provide power or disconnect power supply to the device (or part of the device circuits). The location of the detected face in the image may be used to rotate a display screen to achieve a better line of sight with a viewing person. The difference between the location of the detected face and an optimum is the error to be corrected by rotating the display to the required angular position. A hand gesture detection can be used as a replacement to a remote control for the controlled unit, such as a television set.

A support system (10) and method for the viewer-dependent positioning and alignment of a monitor (20) is disclosed. The support system (10) comprises a central support column (14), a first arm (16) having an adjustable length L, wherein the first arm (16) is rotatably connected at its proximal end to the central support column (14) and is pivotally connected at its distal end to the monitor (20), a second arm (18), wherein the second arm (18) is connected at its distal end to a camera (50), and control means for positioning and aligning the monitor (20) such that irrespective of the angular position of the viewer (i) the monitor (20) is positioned along the line of sight of the viewer pointing towards a reference position, (ii) the distance from the monitor (20) to the viewer (40) is held constant, and (iii) the monitor (20) is at a right angle with respect to the line of sight of the viewer (40) pointing towards a reference position.
摘要:
A projection display is described having two structural support arms for mounting the projection display on a stand or on a bracket. A light engine generates a light pattern to be displayed by the projection display. A bridge plate is positioned between the two support arms and the light engine is mounted on the bridge plate.
