BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates in general to a flat panel display device, and more particularly to a flat panel display device with a hidden cavity.
2. Description of the Related Art
Liquid crystal display possessing the features of lightweight, low power consumption and low radiation has replaced the cathode ray tube (CRT) display and became a standard equipment of computer monitor.
However, the liquid crystal display is more expensive than the CRT display, and the monitor surface of the liquid crystal display is more vulnerable and can be scratched easily. Thus, how to design a display easy to be lifted, shifted or moved has became an imminent issue to be resolved.
SUMMARY OF THE INVENTIONIt is therefore an object of the invention to provide a flat panel display device with a hidden cavity disposed on a surface of the housing for facilitating the user to uplift the flat panel display device. Besides, the flat panel display device further has a moveable cover for covering the cavity, not only preventing the dust but also prettifying the appearance.
The invention achieves the above-identified object by providing a flat panel display device. The display device includes a housing and a cover. The housing has a surface with a cavity. The cover is disposed on the housing for selectively covering the cavity, and is moveable along a direction substabtially parallel to the surface.
The invention achieves another object by providing a flat panel display device. The display device includes a housing and a cover. The housing has a cavity, a protrusion and a lower flange, and the protrusion and the lower flange are formed on the opposite sides of the cavity. The cover is moveably connected with the housing. When the cover is moving toward the lower flange and then located at a first position, the cover adjoins the lower flange and substantially covers the cavity. When the cover is moving toward the protrusion and then located at a second position, the cavity is exposed to allow a user's finger to be inserted into the exposed cavity to uplift the flat panel display device, and the cover is restricted at the second position by the inserted user's finger.
Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiments. The following description is made with reference to the accompanying drawings.

As for the design of enabling the cover 120 to move along the direction parallel to the surface 111 is exemplified and elaborated below.

Moreover, the cover 120 further includes a cover plate 121 and a force-applying portion such as a bump 122 disposed on the cover plate 121 for example. The disposition of the bump 122 depends on the direction of the movement of the cover 120. In the present embodiment of the invention, the bump 122 adjoins a lower flange of the cover plate 121, such that when the user exerts an upward force on the bump 122 to move the cover plate 121, the cover 120 is moved toward the top of the housing 110 from the initial position. On the contrary, when the user exerts a downward force to the bump 122, the cover 120 is moved back to the initial position to cover the cavity 111a.
In the first embodiment, the flat panel display device 100 includes an ejection mechanism 150 for pushing the cover 120 toward the initial position to cover the cavity 111a when no force is exerted on the cover 120. As indicated in
Thus, once the force applied on the bump 122 disappears, the spring 151 provides an elastic force to push the cover 120 back to the initial position.

Any one who is skilled in the technology of the invention will understand that the technology of the invention is not limited thereto. For example, both the positions and the number of tracks and rails can be adjusted to fit actual needs, and so are the positions and the number of gears and gear racks. The number of springs of the ejection mechanism is also adjustable, depending on manufacturing considerations or practical application. In the first and the second embodiments, the cover can be designed to move towards either side of the housing along another direction parallel to the surface. For example, the cover is moved towards the two lateral sides of the housing along a direction perpendicular to the arrow 160. Besides, the third embodiment can incorporate an ejection mechanism such as a torsional spring 440, such that when the force applied by the user disappears, the cover 420 is enabled to rotate towards the lower flange 411b to be located at the first position for covering the cavity 411. Any design of flat panel display device with a hidden cavity selectively covered by a moveable cover for facilitating the user to move the flat panel display device is within the scope of technology of the invention.
According to the flat panel display device disclosed in the above three embodiments of the invention, a cavity is disposed to facilitate the removal of the flat panel display device and is selectivey covered by a moveable cover. The user can move or push the cover to expose the cavity, and uplift the flat panel display device by the cavity. On the other hand, when the cavity is not used, the cover can covers the cavity to prevent the dust and prettify the appearance.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
