Description

Stand for flat panel display {STAND FOR FLAT PANNEL DISPLAY}

The present invention relates to a stand for a flat panel display, and more specifically, to a stand that can adjust the left, right, up and down tilt angles of the display.

As an image display device, a monitor using a cathode ray tube has been widely used for a long time. Recently, the screen of such a cathode ray tube tends to be larger, but as the screen becomes larger, the cathode ray tube itself must also be enlarged. Large monitors not only occupy a large desk space, but the electromagnetic field emitted from the cathode ray tube is known to adversely affect the human body.

Therefore, in order to replace the conventional monitor using a cathode ray tube, various liquid crystal display devices were developed. The liquid crystal display device is supported by the support in the form of a stand, but the stand cannot adjust the tilting angle of the liquid crystal display device. In order to adjust the tilt angle of the display, for example, U. S. Patent No. 5,854, 735 to Cheng, issued December 29, 1998, has been proposed.

As shown in FIG. 1, the liquid crystal display device disclosed in the Cheng patent has a liquid crystal display device 2, a stand 4 supporting the liquid crystal display device 2, and a liquid crystal display device and a stand connected thereto. And a hinge portion 6 having a pivot axis capable of adjusting the angle of the liquid crystal display device up and down.

According to the Cheng patent, the weight of the stand must be quite heavy to stably support the liquid crystal display. In addition, the liquid crystal display and the stand are integrally assembled and marketed by the manufacturer due to the difficulty of assembly. Therefore, it is rather inconvenient to use a flat panel display with a stand.

For example, if the display is to be moved, the stand must also move with the display. In addition, when it is necessary to store the display, a wide storage place is necessary because the stand must be stored with the display mounted.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems, and in particular, to provide a stand for a flat panel display that can easily separate the display from the stand supporting the display.
