Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a multifunctional flat panel display device, and more particularly, relates to a fold-down flat panel display device divided into a display unit and a controller and used as a stand type or a wall tapestry type and having a flexible folder connecting the display unit to the controller.

2. Description of the Related Art

Generally, there are two kinds of flat panel display devices, one is a stand type which a user operates on a desk or other surface and the other one is a wall tapestry type which is hung on a wall.

That is, conventional flat panel display devices as a stand type or wall tapestry type are supposed to be used to perform their own distinct functions. Accordingly, these flat panel display devices are not sufficient for contemporary tendencies and usages, for example, a meeting via a display screen or a personal use.

SUMMARY OF THE INVENTION

Accordingly, the present invention is designed to overcome the drawbacks described as above, and an object of the present invention is to provide a flat panel display device with a composite multifunction, which is separated into a display unit and a power unit and can be used as a stand type to rest on a surface or a wall tapestry type to be hung on a wall.

Additional objects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

To achieve the above and other objects of the present invention, a flat panel display device is provided which includes a liquid crystal display panel for displaying an image, a power unit at a lower end of the liquid crystal display panel, and a display unit having a volume element, for adjusting volume corresponding to the displayed image; a PCB board, a power circuit, an interface port for connecting peripheral equipment and plural jacks are inside a controller unit to which a supporting board is attached to support the display unit at a side when the flat panel display device is to be used as a stand type, and a flexible folder unit, which is a connecting member, which connects the display unit and the controller unit.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made in detail to the present preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. In the following description, well known functions and constructions which may obscure the present invention are not described in detail.

Referring to FIGS. 1 and 2 , a flat panel display device according to an embodiment of the present invention includes a display unit 10 for displaying images, and a controller 20 equipped with an interface port 21 for connecting a PCB board 24 , a control circuit for displaying the images on the display unit which have been received from peripheral equipment.

Also, a connecting member which connects the display unit 10 and the controller 20 is formed with a flexible folder 30 , and the flexible folder 30 is formed with folds.

That is, the display unit 10 is equipped with a flat display screen 11 displaying images, a power switch 12 for turning on/off, the flat panel display device and a volume element 13 for controlling the volume relating to the images displayed on the flat display screen 11 at a vessel plate of a lower part of the flat display screen 11 . The flat display screen 11 is a liquid crystal display screen.

The PCB board 24 , which includes a circuit to control image signals corresponding the images displayed on the flat display screen 11 and other signals, is formed inside of the controller 20 , and an electric source circuit 25 which transfers external electric power to be used to power the flat panel display device is also formed inside the controller 20 . A pair of grooves for wall tapestry 26 is formed in the top surface of the controller 20 to enable the flat panel display device to be hung from a wall as described later on.

The interface port 21 and a plural jack 22 are formed at an end side of the controller 20 , for connecting to peripheral equipment. The supporting board 23 is rotatable to a first position which engages a cutaway portion at the back of the controller 20 ,and to a second position outside of the cutaway portion so as to rest on a surface when the flat panel display device is in the stand type state. As shown in FIG. 3 , a plural engagement chin 23 a , having a number of engagements, for supporting the display unit 10 is formed on the supporting board 23 protruded from the rear of controller 20 when a stand type configuration is used.

The flexible folder 30 enables a front surface of the display unit 10 to contact a front surface of the controller 20 , and a back surface of the display unit 10 to contact a back surface of the controller 20 .

As described above, the flat panel display device according to the embodiment of the present invention is used as a stand type or wall tapestry type.

That is, FIGS. 3 and 4 show a perspective view and a side view of, respectively, the flat panel display device as a stand type. In this case, the supporting board 23 is withdrawn from the cutaway portion of the back of the controller 20 and the display unit 10 is inserted into one of the engagements of the plural engagement chin 23 a of the supporting board 23 formed on the controller 20 . The display unit 10 , the controller 20 and the supporting board 23 form a triangular shape at this time. The flexible folder 30 of the flat panel display device including the display unit 10 and the controller 20 is rotated in a clockwise direction and the supporting board 23 formed on the rear of the controller 20 is folded down. The angle of orientation of the display unit 10 may be adjusted depending upon into which one of the engagements the end of the display unit 10 away from the flexible folder 30 is inserted.

In case the supporting board 23 is folded down and the display unit 10 is inserted into the plural engagement chin 23 a formed on the supporting board 23 according to a required angle, the flat panel display device is locked by the plural engagement chin 23 a into one of the engagements by forming a stabilized triangular shape.

As a result, the flat panel display device is used as a stand type in this instance, because the display unit 10 is settled in the supporting board 23 formed on the controller 20 .

FIG. 5 shows a state in which the flat panel display device is used as a wall tapestry. To place the flat panel display device in the wall tapestry state from the stand type state, the display unit 10 is detached from the plural engagement chin 23 a and the supporting board 23 is rotated into the cutaway portion at the back of the controller 20 , so that the back surface of the controller 20 is flat (the back surface of the support board 23 being coincident with the back surface of the controller 20 ). The display unit 10 is rotated (counter clockwise from the state shown in FIG. 4 ) about the flexible folder 30 , which bends, until the back of the display unit 10 is in contact with the back of the controller 20 . FIG. 5 shows the flat panel display device in the wall tapestry state, such that the supporting board 23 has already been received within the cutaway portion of the back of the controller 20 after the display unit 10 is detached from the engagement chin 23 a of the supporting board 23 , and the back surfaces of the display unit 10 and the controller 20 are completely in contact.

In the wall tapestry state shown in FIG. 5 , nails or other protrusions extending from a wall may be inserted into the grooves for wall tapestry 26 formed on the front of the controller 20 of the flat panel display device.

Therefore, as above described, the flat panel display device according to the present invention is used optionally according to a necessity of a user as a flat panel display device for standing on a surface and a flat panel display device for hanging on a wall.

Although an embodiment of the present invention has been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
