Abstract

PURPOSE:To ensure an easy-to-see screen at all times by supporting movably a display device via a main body almost in an arc shape and therefore keeping the eyes of a user almost rectangular to the display screen despite the movement of the display device. CONSTITUTION:A support member 4 attached to main body 1 interlocks an arc-shaped slide groove 3 provided on the back of a liquid crystal display device 2. Then the device 2 can be tilted with no step and automatically via a pinion 7 and a rack 5 with actuation of a motor 6. Furthermore the device 2 can be tilted in an arc shape owing to the arc-shaped groove 3. Thus it is possible to keep the eyes of a user rectangular to a display screen. Then an easy-to-see screen is always secured for the user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to display devices such as liquid crystal display devices for personal computers, word processors, workstations, etc.

[Prior Art] Some conventional liquid crystal display devices are capable of tilting and swivel in a straight line.

In this display device, reflection can be prevented by tilting and swivel.

[Problem to be solved by the invention]

However, when such a display device is tilted or swiveled, the user's line of sight is no longer perpendicular to the display screen, making it difficult to see the display screen.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a display device whose display screen does not become difficult to see even when moved.

[Means for Solving the Problems] In order to achieve this object, in the present invention, a display device movably supported by a main body is supported movably in a substantially arc shape.

[Effect]

In this display device, the user's line of sight can be kept substantially perpendicular to the display screen even when the user moves.

〔Example〕

FIG. 1 is a schematic diagram showing a personal computer having a liquid crystal display device according to the present invention, and FIG. 2 is an A-A in FIG.
FIG. In the figure, 1 is the main body, 2 is a liquid crystal display device, 8 is a keyboard, 3 is an arcuate slide groove provided on the back side of the liquid crystal display device 2, 4 is a support attached to the main body 1, and 4 is a support. is engaged with the slide groove 3.

5 is a rack attached to the back side of the liquid crystal display device 2;
is a motor attached to the main body I, and the motor 6 can be controlled by key operations on a keyboard 8. 7 is a pinion attached to the output shaft of the motor 6, and the pinion 7 meshes with the rack 6.

In this liquid crystal display device, the support 4 is connected to the slide groove 3.
2, it is possible to tilt the liquid crystal display device 2. Moreover, since the slide groove 3 is arcuate, the liquid crystal display device 2 can be tilted in an arcuate manner, so that the user's line of sight can be kept perpendicular to the display screen, as shown in FIG. This prevents the display screen from becoming difficult to see. In particular, although the liquid crystal display bag N2 has a narrow viewing angle, the user's line of sight can be kept perpendicular to the display screen of the liquid crystal display device 2, so visibility is good. Further, when the motor 6 is operated, the liquid crystal display device 2 can be automatically and steplessly tilted via the pinion 7 and the rack 5.

Furthermore, since the motor 6 can be controlled by key operations on the keyboard 8, the tilt angle of the liquid crystal display device 2 can be controlled by operating the keyboard 8.

In the above embodiments, the case where the display device is the liquid crystal display device 2 has been described, but it is clear that the present invention can be applied to plasma display devices and the like. Further, in the above embodiment, the liquid crystal display device 2 is supported in a tiltable manner, but by providing the main body l with a swivel mechanism having a structure similar to the tilt mechanism shown in FIGS. may be swivelably supported. Furthermore, in the above embodiment, the liquid crystal display device 2 is supported in a tiltable manner, or the main body 1 is provided with a swivel mechanism having a structure similar to the tilt mechanism shown in FIGS. By providing this, the liquid crystal display device 2 can be moved spherically.

Further, in the above embodiment, the rack 5 and the pinion 7 are used as the automatic moving mechanism, but a belt-driven automatic moving mechanism may also be used, and in this case, the noise is quiet. Further, in the above embodiment, the liquid crystal display device 2 is tilted steplessly, but the liquid crystal display device 2 may be tilted stepwise.

[Effects of the Invention] As explained above, in the display device according to the present invention, the user's line of sight can be kept almost perpendicular to the display screen even if the user moves, so the display screen does not become difficult to see. do not have. As described above, the effects of this invention are remarkable.
