Portable Display Device

According to the present invention, in constructing one large screen using two or more displays, a plurality of displays can be folded or unfolded, and when the display is unfolded, the display can be brought into contact with each other, thereby minimizing the seam that is the boundary of the display. It relates to a display device.

The construction of one large screen using two or more displays has been applied to large display devices. Recently, the necessity of a large screen has been increased as the performance is improved due to the performance of wireless Internet, etc., in a portable display device. In the portable display device, the large screen does not use portable characteristics such as size and movement, and thus a folding display is adopted. One portable display device has been proposed.

In general, a flat panel display is used for a portable display device, and a flat panel display includes a liquid crystal display (LCD), a field emission display (FED), a plasma display panel (PDP), and an electro luminescent (EL).

In a portable display device employing a multi-display, a folding display has been proposed to increase portability. However, in such a folding display, when the packaging housing with the display is unfolded, the display does not have a structure in which the display can directly touch each other. Next, there was a disadvantage that an operation such as sliding is required.

In other words, when the panel housing is unfolded, the sides of the display cannot be brought into contact with each other at once, so that an additional component for this purpose is provided in the portable display device, or the display is brought into contact with each other when the display is unfolded. There is a problem.

Accordingly, the present invention has been invented to solve the above-described problems of the prior art, and can fold or unfold a panel housing equipped with a plurality of displays, and unfold the panel housing so that the sides of the display touch each other at the same time. It is an object of the present invention to provide a foldable portable display device which can be mounted on the panel housing to protect the display from external shocks, even though the display side is exposed to the panel housing side.

In order to achieve the above object, the present invention provides a collapsible panel housing comprising at least two or more circuits and a central processing unit mounted therein, and a display mounted on a side of the panel housing. When folded, it is characterized in that the side of the display seam coincides with the extension of the side of the panel housing.

Also, the distance from the center of rotation of the display to the first display and the distance to the second display are the same. The distance from the center of rotation to the display is the distance from the center of rotation to the input device when the input device is provided at the top of the display, and the distance from the center of rotation to the protection plate when the display is provided with a protection plate.

Preferably, a pedestal is provided on the side of the panel housing, and a display is mounted on the pedestal top.

The display may also be mounted to the panel housing by a chassis, which chassis integrally surrounds the display assembly.

In addition, the chassis also surrounds the side of the display seam, and has a structure that surrounds only the display side in the display seam.

In still another embodiment of the present invention, a fixing member is provided in the chassis so that the chassis is mounted to the panel housing, and the fixing member is mounted by the fixing member locking means of the panel housing, and between the side of the display joint and the fixing member. The distance of is characterized in that the same as the distance between the side of the panel housing joint portion and the fixing member locking means.

In addition, the distance between the display joint side and the fixing member is smaller than the distance between the fixing member locking means and the panel housing side, and the small degree may be within 1.5 mm.

When the folded panel housing is unfolded, the displays are adjacent to each other within a distance of 3 mm. In addition, when the folded panel housing is unfolded, the display is unfolded through the rotational movement, and at least one side is brought into contact with each other or adjacent to a distance within 3 mm.

On the other hand, the panel housing further includes a side opening for protecting the display side exposed to the opening, the side opening is formed thinner than the panel housing side.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to an accompanying drawing.

The present invention provides a folding portable display device having an effect of viewing at least one screen by connecting at least two flat panel displays adjacent to each other. As the flat panel display panel, LCD, FED, PDP, Electric Paper, etc. may be used.

The present invention allows two or more flat panel displays to be located adjacent to each other, so that two or more flat panel displays can have the same effect as using one display. At this time, having two or more displays adjacent to each other does not necessarily mean making the display touch each other. That is, two or more displays need to be very close so that two or more displays can be viewed as one display. In the Korean dictionary, the word "adjacent" is used to describe both the meaning of "near and near" and "to be close to each other."

1 is a view showing an open state of a foldable portable display device of the present invention.

As shown in FIG. 1, the foldable portable display device of the present invention includes two displays 2 and 4 and two panel housings 20 and 40 on which the display is mounted. One side of the display 2, 4 is in contact with each other to form a screen. To this end, when the two panel housings 20 and 40 are in contact with each other, two displays 2 and 4 should be mounted at the boundary surface. That is, as shown in FIG. 1, the panel housings 20 and 40 and the display 2 and 4 closely adhere to each other to minimize the seam that is the boundary between the two displays 2 and 4.

In addition, the two panel housings 20 and 40 are connected by a connecting means 6 that can be folded and unfolded. In this embodiment, a hinge is used as the connecting means 6.

In the folded state of the display device, an opening 8 is formed in the side surfaces of the panel housings 20 and 40, and one side of the display 2 and 4 is exposed in the opening 8. Therefore, when the display device is unfolded, one side surfaces of the panel housings 20 and 40 are brought into close contact with each other, and the sides of the display 2 and 4 are also brought into close contact with each other through the opening 8 of the closely contacted part. The seam that is the boundary of 4) is minimized to form a screen.

3 is a view showing a form in which one display 2 is mounted on one panel housing 20.

As shown in FIG. 3, the panel housing 20 cuts the side surface 20a to form an opening, and the display 2 side surface is exposed on the extension line of the cut side surface. In addition, a cover 24 having a “C” shape is formed on the outer surface of the panel housing 20 to cover and protect the edge of the display 2. Although not shown here, another pair of panel housings 40 and the display 4 are also formed in the same structure.

4 is a cross-sectional view showing the cross-sectional structure of FIG.

As shown in FIG. 4, the side surfaces 20a and 40a of the panel housings 20 and 40 are cut to form the opening 8 so that the display 2 is extended on the cutout sides 20a and 40a. The side surface of () 4 is made to match. When the display device is folded, the display spaces are separated from each other by the covers 24 and 44, that is, the displays 20 and 40 are separated from each other. On the other hand, inside the panel housings 20 and 40, that is, inside the displays 2 and 4, various circuits constituting a portable display device and a central processing unit or a transmitting and receiving device 25 and 45 are mounted.

In FIG. 4, the distance from the cutout surface 20b of the first panel housing 20 to the center of rotation is determined based on the extension of the panel housing side surfaces 20a and 40a and the center of rotation, and H, the thickness of the first display. L, the distance from the cutting surface 40b of the second panel housing 40 to the center of rotation is H1, and the thickness of the second display is L1. When the display device is folded, the distance between the two displays (2) and (4) is reduced. To what extent should be obtained by the following relationship.

H-L = H1-L1 ------ (1)

In the above equation, the difference between the distance H from the cutting surface 20b of the first panel housing to the center of rotation and the thickness L of the first display is from the cutting surface 40b of the second panel housing to the center of rotation. It is equal to the difference between the distance H1 and the thickness L1 of the second display. That is, the distance H-L in a straight line with the first display at the center of rotation is equal to the distance H1-L1 in a straight line with the second display at the center of rotation. On the other hand, the meaning of the same distance in the present invention is usually the same meaning when viewed with the naked eye, it will be understood as an error level within 1 mm.

As described above, in the present invention, when the display is folded, the display is disposed on the side surfaces 20a and 40a of the panel housings 20 and 40 which are cut away from the center of rotation by the same distance from the first display 2 and the second display. (2) (4) is mounted. Therefore, when the two displays 2 and 4 are unfolded and the two displays are in contact with each other, when the display device is unfolded, the heights of the surfaces of the two displays 2 become the same as shown in FIG. 1. In addition, when an input device such as a touch panel or a protective plate is mounted on the top of the display, the distances from the rotation center to the input device or the protective plate are equal to each other.

In the above embodiment, the side is cut off when the opening is formed, but the present invention is not limited thereto. For example, the opening of the side may be made in advance on a mold to be immediately made by injection.

With this structure, when the folded panel housings 20 and 40 are unfolded, the displays 2 and 4 respectively mounted to the panel housings 20 and 40 may be brought into contact with each other through the rotational movement. However, it is not necessary to make contact with each other, and when the panel housings 20 and 40 are unfolded, it is possible to achieve the object of the present invention when the respective displays 2 and 4 are brought close to each other within a distance of 2 mm or less. .
