The present invention relates to a permeable liquid screen device, a manufacturing method thereof and a screen aqueous solution composition. Specifically, a transmissive liquid screen is formed by spraying a liquid containing a light diffusing agent to form a projection film, and projecting the image behind the formed projection surface so that the desired image can be expressed while penetrating the projection film. The present invention relates to an apparatus, a method for manufacturing the same, and a screen aqueous solution composition.

The screen is a plate-shaped member that emits various images in the form of a beam and reflects or transmits the emitted images to form an image on a projection surface. Such screens are applied to a large number of areas such as movie screenings in theaters, event video representations in large halls or auditoriums, indoor and outdoor advertising videos, and office presentation presentations.

The screen as described above is manufactured and provided in the form of a wall-mounted type, a stand movable type, a blind type or the like according to the installation form thereof. In particular, such a screen may be classified into a reflective type and a transmissive type according to the emission position of the image. In the case of the reflection type, the image is emitted from the front, and in the case of the transmission type, the image is emitted from the rear.

For reference, since the wide screen movies have been made as a countermeasure against the television since the 1950s, the installation of large screens with full fronts becomes inevitable. As a result, it is applied to the cinema size of 1: 2.35 from the aspect ratio of 1: 1.6 to 1: 1.85, and it is currently used as needed.

The screen is mainly made of a material of synthetic resin (for example, polyester), and is provided in the form of a square plate of various sizes according to the film size of the projection device for emitting an image and the size of the space to be installed. On the other hand, while the small screen is implemented as a single member, the large screen is generally configured to be able to represent a large image by connecting and connecting a plurality of screens.

The conventional screen made of the synthetic resin is inconvenient to transport and store the screen because it is made in the form of a solidified plate. In particular, the solidified screen is subject to the constraints of the place at the time of installation, since the solid screen is mainly installed on the wall, as the size of the screen increases, securing the space for installing the screen and supporting the surroundings by the size and weight of the screen Problems that are cumbersome to install the apparatus arise.

The present invention has been invented to solve the above problems. Accordingly, an object of the present invention is to provide a liquid screen device in which the screen is formed by spraying a liquid containing a light diffusing agent, and thus there is no inconvenience in transportation and storage and no restriction occurs in the installation place.

Another object of the present invention is to provide a method of manufacturing the screen device of the optimized process for manufacturing the screen device, the projection screen is formed by the produced screen device.

Still another object of the present invention is to provide a composition of an aqueous screen solution, which is prepared by the method of manufacturing the optimized screen device and forms a projection film.

In order to achieve the above object, the present invention has the following configuration.

The present invention is a screen in which the image emitted by the projection apparatus is transmitted from the rear, the pipe which is installed in at least one of the both sides spaced apart from each other at a predetermined distance from the upper surface spaced from the ground to spray the aqueous solution so that the projection film is formed A nozzle; A drain container installed below the drop of the aqueous solution to collect the aqueous solution; It is connected to the nozzle and the drain container is configured to include a pump to advance the aqueous solution to the pipe nozzle and spray, and circulate the aqueous solution collected in the drain container.

Here, the pipe nozzle and the pipe body is supplied with an aqueous solution therein; It is comprised including the nozzle body arranged in multiple numbers in the longitudinal direction of the said pipe main body. In particular, the pipe nozzle is configured by connecting a plurality of pipe bodies are piped. In addition, the pipe nozzle is formed such that the inner diameter of the pipe main body becomes smaller as the inside of the pipe main body moves away from the supply side end of the aqueous solution, so that the injection pressure in the nozzle body is uniform.

On the other hand, the pipe nozzle is installed to be coupled to the upper portion of the support standing up from the ground. In particular, the support is provided with an expansion unit for adjusting the installation height of the pipe nozzle in the upper and lower coupled with the pipe nozzle.

In order to achieve the above another object, the present invention, in the process of manufacturing a screen device for transmitting the image emitted from the projection apparatus to represent the desired image,

Mixing pure water and a light diffusing agent to form an aqueous solution; And installing a pipe nozzle to spray the aqueous solution to form a projection film, and supplying and spraying the aqueous solution to the pipe nozzle by a pump to form a projection film.

In order to achieve the above another object, the present invention is formed so that the aqueous solution is mixed by the optimized composition of pure water and the light diffusing agent to form a projection film which can increase the light diffusivity and the sharpness of the image.

Hereinafter, exemplary embodiments of the present invention to which the above configuration is applied will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram of a screen device according to the present invention, Figure 2 is a perspective view of the screen device according to the present invention, Figure 3 is an enlarged perspective view of a pipe nozzle of the screen device according to the present invention, Figure 4 is a screen device according to the present invention Pipe nozzle enlarged cross-sectional view.

Referring to the drawings, the screen device according to the present invention has a configuration consisting of a support 10, a pipe nozzle 20, a drain container 30, a pump 40. In such a screen device, the aqueous solution W containing the light diffusing agent is injected through the pipe nozzle 20 to form the liquid projection film S in the air. That is, since the projection screen S transmits the image emitted from the rear projection device P to the liquid screen to represent the image, the screen device should be installed in front of the projection device P that emits the image. As described above.

For reference, the projection device is a device for enlarging and projecting an image photographed on a film onto a projection screen using a light source and a lens device. That applies.

The support 10 is installed standing up to a certain height (set in view of the height of the screen is formed) on the ground. In particular, the support 10 is installed while maintaining a pair of mutually constant interval (set in consideration of the interval to become the width of the screen).

Although the support 10 is shown in the form of a square pillar on the drawing, any support that maintains a constant height and a mutual space can be manufactured in a steel structure or other structures.

The pipe nozzle 20 is configured by combining a horizontal nozzle 21 having both ends fixedly installed on an upper portion of the support 10, and a vertical nozzle 22 connected downward from the horizontal nozzle 21. At this time, the vertical nozzle 22 is coupled to both ends (points inside the support) of the horizontal nozzle 21. In particular, the vertical nozzle 22 and the horizontal nozzle 21 are in communication with each other to form a passage through which the aqueous solution for forming the screen from the outside.

In such a pipe nozzle 20, the horizontal nozzle 21 and the vertical nozzle 22 are constituted by a pipe main body 23 and a nozzle body 24. The pipe body 23 is mainly configured to supply the aqueous solution W into the pipe of a circular shape (polygon according to the producer's choice). The nozzle body 24 is arranged in plural in the longitudinal direction of the pipe body 23.

In this configuration, the nozzle body 24 is shown coupled to the outer surface of the pipe body 23 in the drawing, but may be drawn into the inside of the pipe body 23 to be concealed and coupled. In particular, the nozzle body 24 may be formed integrally with the pipe body 23 if it can be manufactured from the same material as the pipe body 23.

In addition, the pipe nozzle 20 may be configured as a single body of the pipe body 23, but is preferably implemented in a configuration that combines a plurality of pipe joints. That is, the pipe main body 23 is formed to have a certain length (length that is easy to store and carry), and is formed by forming a coupling structure (pipe joint) of female and male on both sides thereof. In the drawing, the female and male coupling structures are the threaded portions 25 formed at both ends of the pipe main body 23. Here, a sealing member made of rubber material may be interposed between the female and male threads 25 coupled to each other. At this time, the pipe joint can be detachably coupled to the pipe on both sides via a separate pipe joint member.

The pipe nozzle 20 configured as described above is configured to be formed on the upper and both sides as described above to form the projection film S described above, but the pipe nozzle 20 is installed only on one or both sides of the upper or both sides. The projection film S may be formed in the air. When the pipe nozzles 20 are installed only on one side or both sides, the aqueous nozzles W have fewer injection points, so that a more dense projection film S cannot be obtained. Preferably, the pipe nozzles 20 are installed on the upper and both sides. As a result, a screen device capable of representing more detailed images is realized.

The drain container 30 is configured to collect the aqueous solution (W) that is sprayed from the pipe nozzle 20 falls. That is, the aqueous solution W collected in the drain container 30 is supplied to the pipe nozzle 20 by the pump 40 and reused.

In particular, the drain container 30 as described above may selectively set the discharge point when the aqueous solution (W) is collected and discharged to one side as shown in FIGS. 5A and 5B. FIG. 5A is a configuration for discharging the collected aqueous solution W to approximately the center, and is configured such that the bottom surface 31 for moving the aqueous solution W has an incline upwardly outward from the discharge point. Figure 5b is configured to discharge the collected aqueous solution (W) to one end point, the bottom surface 31 is configured to have an inclined upward to the other side based on the discharge point.

The pump 40 is connected to the nozzle 20 and the drain container 30 so as to spray the aqueous solution (W) to the pipe nozzle 20, the configuration for circulating the aqueous solution collected in the drain container (30) to be. Such a pump 40 may be implemented in a variety of mechanical or ejection configuration, the pump 40 is a pipe nozzle 20 and the drain container 30 by a hose or pipe for the aqueous solution (W) to proceed. Of course, each is connected to).

6 is a flowchart of a process of manufacturing a screen device according to the present invention.

Referring to the drawings, in order to manufacture the screen device according to the present invention to prepare an aqueous solution (W) for forming a projection film (S). At this time, the aqueous solution (W) is prepared by mixing pure water (W1) and light diffusing agent (W2) in order to obtain high transmittance and light diffusivity. In particular, the aqueous solution (W) may be added to the antifreeze (W3) with water (W1), light diffusing agent (W2), which is optional when you want to form a projection film (S) in a low temperature environment, such as winter It can be mixed and added.

At the same time, in order to perform the installation work for forming the projection film (S), the position to be installed on the screen is selected, and the support (10) is installed corresponding to the width of the projection film (S) to be formed. Thereafter, when the pipe nozzle 20 and the drain container 30 are installed on the support 10, the basic installation work for forming the projection film S is completed.

When the basic installation is completed as described above, the pipe nozzle 20 and the drain container 30 is connected to the pump 40, at this time, the pipe nozzle 20 and the drain container 30 is the pump 40 Configure to have a loop through.

Thereafter, when the pump 40 is driven and the above-described aqueous solution W is supplied, the aqueous solution W is supplied to the pipe nozzle 20 by the pump 40, and the aqueous solution supplied to the pipe nozzle 20 ( W is diffused to the outside through the nozzle body 24 and sprayed to form a projection film S of liquid in the air (section in which the aqueous solution of the pipe nozzle is injected).

When the projection film S is formed as described above, an image is output by driving the projection device P provided behind the projection film S, and when the projected image passes through the liquid projection film S, the projection film S is applied to the projection film S. The desired image is represented.

In the formation of the screen as described above, the aqueous solution (W) is 20% by weight or more and 1% by weight or more of light diffusing agent (W2) having particles having a size of 2 μm or more and 20 μm or less with respect to 100% by weight of the total, and pure water (W1). ) Is prepared by mixing at least 81% by weight to 98% by weight.

At this time, when the light diffusing agent (W2) has a unit particle size (particle size) of less than 2㎛, the increase in the purchase cost and the light refraction and scattering efficiency is lowered within the selected mixing capacity, high light diffusion (brightness efficiency) It is hard to expect). On the contrary, when the light diffusing agent W2 has a unit particle size of more than 20 μm, the content within the selected mixing capacity is small, which is difficult to expect high light diffusivity, thereby making the expressed image unclear.

In addition, when the light diffusing agent (W2) has a content of less than 1% by weight, it is difficult to obtain a clear image because the content of the light diffusing agent (W2) per unit section of the projection film (S) is small. On the contrary, when the light diffusing agent (W2) is contained in excess of 20% by weight, an excessively large amount of the light diffusing agent (W2) is contained, thereby increasing the manufacturing cost and increasing the scattering rate of the image, making it difficult to express a clear image.

Experimental Example

After varying the particle size and the mixing amount of the light diffusing agent (W2) in the composition of the aqueous solution (W) as described above, and fed to the screen device described above, the projection film was formed and the image was transmitted to measure the sharpness of the expressed image. . In the measurement method, the luminance meter and the recording device were arranged at the 10m point in front of the projection screen to obtain the brightness of the image emitted from the projection screen and the clarity of the image recorded in the recording device. The results are shown in Table 1 below.
