The present invention relates to an image display screen device, and more particularly to.

In general, a screen device is mainly used to display an image projected from an image projector (i.e., a projector), and the screen device is formed by applying or adhering a screen film onto a base film fixed or wound on a wall. .

Such a screen apparatus is advantageous in that a video signal applied to the image projection apparatus can be implemented in a large screen, but usually displays an image from the image projection apparatus in a front projection method or a rear projection method depending on the shape of the screen film. Done.

Therefore, at present, one screen device can display only an image projected from one image projection device, that is, in the case of a front projection method or a rear projection method, the image can be observed only in front of the screen device.

That is, for example, an LCD device to which an LCD panel is applied or an LED device to which an LED panel with a plurality of LED elements is mounted, when a plurality of LCD panels or a plurality of LED panels are installed to face different directions, the image is observed in multiple directions. This is possible, but in the case of a screen device displaying an image from an image projection apparatus (ie, a projector), only image observation in one direction is possible, so that image display in multiple directions is possible for the screen apparatus. The structure for this is preferred.

Accordingly, the present invention has been made in view of the above-described circumstances of the prior art, and forms first and second screen films on both sides of a light shielding panel, and transparent first and second cover members on the first and second screen films. It is an object of the present invention to provide an image display screen device in which the image display in at least two directions is possible by forming the unit integrally.

In order to achieve the above object, according to a preferred embodiment of the present invention, first and second screen films are formed on both sides of a central light blocking member, and first and second transparent films are formed on each of the first and second screen films. A cover member is bonded to each other, and an upper portion and a lower portion of the light blocking member, the first and second screen films, and the first and second cover members are provided with an image display screen device in which an upper surface fixing member and a lower surface fixing member are combined.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded view for explaining the structure of an image display screen device according to a preferred embodiment of the present invention, Figure 2 is a view showing an assembled state of the image display screen device according to the present invention shown in FIG.

In the image display screen device 10 shown in the drawing, a light blocking member 20 formed of a non-translucent material is disposed in the center thereof. Examples of the material of the light blocking member 20 include rubber, synthetic resin, wood, and paper. ), Metal / nonferrous metal or alloy, glass of light reflection coating.

In addition, according to the image display screen device 10, the first screen film 24 is coated or adhered to one side of the light blocking member 20 between the first cover member 22 made of transparent synthetic resin or glass. Is formed by.

In addition, the second screen film 26 is coated or bonded to the other side of the light blocking member 20 in the same or similar manner as the first screen film 24, and the second screen film 26 is formed on the second screen film 26. The same second cover member 28 as the first cover member 22 is provided.

Here, the upper and lower sides of the first cover member 22, the first screen film 24, the second screen film 26, and the second cover member 28 arranged around the light blocking member 20. The upper surface fixing member 30 and the lower surface fixing member 34 is provided.

Preferably, the upper surface fixing member 30 and the lower surface fixing member 34 has a coupling groove (see the lower surface fixing member in Figure 1) is formed on both sides of the light blocking member 20 as illustrated in FIG. The upper and lower sides of the first cover member 22 and the first screen film 24 and the second screen film 26 and the second cover member 28 are, for example, adhesively bonded or screwed together. It is firmly supported by

In addition, the upper surface fixing member 30 is provided with a plurality of annular portions 32 assuming that the corresponding image display screen device 10 is installed on the ceiling, for example.

Accordingly, the image display screen device 30 according to the present invention is fixed to the ceiling using the annular portion 32 of the upper surface fixing member 30 in the form illustrated in FIG. 3 on both sides thereof. When an image is projected from the second image projector (i.e., projector) 40, 42, the image can be observed in two directions.

Here, the first and second screen films 24 and 26 of the image display screen device 10 may be projected even if the same image is projected from the first and second image projectors 40 and 42 or different images are projected. ) Are blocked by the light blocking member 20 in the middle so that interference of the image is not caused.

On the other hand, the present invention is not limited to the above examples and various changes and modifications can be made within the scope not departing from the technical gist and gist of the invention.

That is, in the above description, a structure in which the first and second screen films are formed on both sides of the blocking member is described, but the light blocking member is formed of a triangle, a square, a pentagon or more polygon, and the screen film and the transparent cover are formed on each light blocking member. The member may be provided so that the image is projected from the corresponding image projection apparatus.

As described above, according to the image display screen device according to the present invention, a screen film is formed on both sides of the light shielding member, and a cover member is adhered on the upper side thereof, thereby forming a two-way image display structure and corresponding to each image display structure. By allowing the same or different images to be projected from the image projector (projector), image observation in multiple directions is possible.

In addition, the image display screen device according to the present invention, because only the screen film and the transparent cover member is mounted on both sides of the light blocking member, it is possible to implement a large screen at a lower cost than LCD devices or LED devices.

Claims (1)

First and second screen films are formed on both side surfaces of the central light blocking member, The first and second transparent cover members are bonded to each of the first and second screen films, And an upper surface fixing member and a lower surface fixing member are coupled to upper and lower sides of the light blocking member, the first and second screen films, and the first and second cover members.
