Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 10-2006-0053633 filed with the Korean Intellectual Property Office on Jun. 14, 2006, the disclosure of which is incorporated herein by reference in its entirety. BACKGROUND [0002] 1. Technical Field [0003] The invention is related to a display rotation apparatus and rotating method thereof. [0004] 2. Description of the Related Art [0005] Flat panel displays, such as TV's or monitors employing LCD, PDP, LED, etc., provide the benefit of allowing efficient use of spaces, and are fast replacing Braun tube TV's and monitors. The increase in demand for such flat panel displays is expected to continue into the future. In particular, flat panel LCD or PDP TV's, often referred to as “wall-mount TV's,” are fixedly attached to wall surfaces for use. When viewing a wall-mount TV thus fixed, the largest viewing angle is achieved directly in front of the TV. [0006] However, when th...

AI Technical Summary

Benefits of technology

[0007] An aspect of the invention is to provide a display rotation apparatus that maintains the advantage of wall-mount TV's in utilizing an indoor space efficiently and achieves the largest viewing angle even when a viewer changes his position.

[0009] A moving body may include a very display. But, when a moving body may be distinguished from a display, a display rotation apparatus may further comprise a display hinge coupled to the moving body and a rotation part, coupled to the moving body, rotating the display about the moving body. This configuration couples the display to the moving body in some distance and enables the display to rotate in variable directions.

[0010] Also, a rotation part may comprise a tension member coupled to two points on the display opposite to each other about the rotation axis of the display, a roller member configured to guide the path of the tension member and a motor part positioned on the path of the tension member and configured to apply a tensile force on the tension member. The rotation part may provide the power the display to rotate about the moving body.

[0013] A driving part may comprise a power part generating rotation force and a rotation part receiving the rotation force from the power part. And a rotation part comprise a rotating driving axis coupled to the power part, a clutch part coupled to the driving axis and a a driven axis contacting the clutch part. It may be preferable that the rotation force of driving part is smaller than the friction force between the clutch part and the driven axis. Also, it may be preferable that the friction force between the clutch part and the driven axis is smaller than the cogging torque of the power part. The driving part provides the power to expand and contract the arm part. The configuration of the rotation part prevent the damage of motor by compulsory rotation.

[0016] Also, when plural distance detecting sensors are attached to the moving body and configured to generate signal corresponding to the distance between the moving body and the fixed body, the rotation method may further comprise receiving the distance signal from the distance detecting sensor after rotating the driving part and stopping the rotation of each driving part, if the distance between the moving body and the fixed body meets the predetermined tolerance by processing the distance signal. This rotation method may prevent the display to collide against the fixed body.

[0017] Meanwhile, the rotation method may further comprise determining a comparative value by measuring rotation amount the of the driving part after rotating the driving part; rotating the driving part, if the difference between the comparative value and the base value exceeds the tolerance, by comparing the comparative value and the base value; and stopping the rotation of the driving part when the difference between the comparative value and the base value meets the tolerance, by repetitively performing the rotating and the determining. The display may positioned accurately by repetitive loops.

Problems solved by technology

However, when the TV is fixed to a wall surface, the position that allows the largest viewing angle of the TV screen is also fixed, and as a viewer changes his position, adequate viewing may not be obtained.

It is difficult to modify the TV's position with the conventional wall-mount TV, because there is little or no distance between the TV and the wall, and even if the TV is spaced from the wall surface by means of additional members, it is not possible to rotate the TV to a desired orientation.

Also, attempting to resolve such problems using an apparatus to maintain some distance may result in another problem of degrading the elegant appearance and the efficiency in utilizing an indoor space, which are important benefits of wall-mount TV's.
