Where "one" is either end of the member, "other" means the other end of the same member.

At this time, the horizontal stage 120 bonded to the top end of the vertical stage 110 is inclined at a predetermined angle toward the ceiling, or the horizontal stage 120 bonded to the bottom end of the vertical stage 110 is inclined at an angle toward the ground. It can be bonded to the screen frame having a more stable curvature (see Fig. 6).

The support is basically a structure comprising a vertical stand 110 having a skeleton fixed from the bottom and a horizontal stand 120 one end joined to the vertical stand 110 and the other end joined to the screen 10 having a frame or curvature. It is called.

The vertical stand 110 and the horizontal stand 120 are skeletal materials of a structure installed to support the screen 10 having the curvature and the frame of the screen having the curvature, and are preferably made of a solid material. In addition, the horizontal stage 120 may be manufactured to have different lengths because the distance from the vertical stage 110 to the respective portions of the screen 10 having the curvature is different due to the curvature of the screen due to the characteristics of the screen 10 having the curvature. In particular, it is preferable that a line connecting each other end of the horizontal stage 120 arranged on the same horizontal axis forms a curved shape having the same curvature value as the curvature of the screen frame having the curvature. In addition, the vertical stand 110 and the horizontal stand 120 may be made to change the length of the screen under the control of the theater server can change the shape of the screen.

Meanwhile, the vertical stand 110 and the horizontal stand 120 can fix the horizontal and vertical connecting portions first by using the frame connecting joints, and the welding work is performed secondarily to the site that is subjected to a lot of loads to create a more solid joint. Can be.

Here, the screen 10 having a curvature generally refers to a projection surface made of various materials bonded to a frame for grasping the screen, and has a curvature of a predetermined size along a horizontal axis or a vertical axis according to the curvature of the long axis member or the short axis member constituting the frame. It refers to the screen that will have. At this time, the perforations are uniformly formed as a whole of the screen, which is made larger than the frame, and has a curvature in such a manner as to bind the screens to the pillars constituting the major and minor members of the frame (see FIG. 6) using a string. It is desirable to take the shape of).

In addition, the material of the screen 10 having a curvature may include various types of coatings on a fabric or a fabric such as matt white, glass beads, ultra beads, film, fiberglass, diamond, and the like. In this case, the reflectance value GAIN of the screen preferably has a value of 1.8 to 2.4 for 3D polarization screening, and the higher reflectance value means that the higher the reflectance of the light, the brighter the image.

In addition, the frame (see FIG. 6) means a structure joined to the support to maintain the shape of the screen 10 having a curvature, the frame is provided with a long axis member or a short axis member having a curvature, the screen is the member It adheres to the fields, and ultimately plays a role in realizing a screen 10 having curvature. At this time, the long axis member is a member longer than the short axis member, it is preferable that the long axis member in the horizontal axis, the short axis member in the longitudinal axis direction in view of the characteristics of the screen installed in the theater. In this case, the long axis member of the frame includes a first long axis member and a second long axis member that respectively mount the upper and lower ends of the screen.

The frame may be deformed to have various curvatures according to lengths of the vertical stand 110 and the horizontal stand 120 provided in the screen support 100 having the curvature. Thus, the frame is preferably an elastic material. It can be prepared as.

On the other hand, the term "bonding" used in the present invention means that the independent member is in contact with each other, and includes bundles, attachments, bonds, bonds, welding, and mounting, and the screen and frame are joined using a string. Obviously, it is not limited to the method of tying. Therefore, a method of additionally attaching the magnetic member to the screen 10 and the frame having the curvature in the manner of bonding, the intake means attached to the frame so that the screen 10 having the curvature is in close contact with the frame or the frame Various methods, such as a method of applying the adhesive material to bring the curvature of the screen 10 into close contact with each other, may be considered.

The definition of curvature used in the present invention is as follows. When point P on the curve moves at a constant speed along the curve, the direction of travel changes with the distance traveled (the length of the arc of the curve) s. The rate of change at this time is called the curvature of the curve. If the minute travel distance from one point P to Q on the plane curve is s, and the angle (in increasing direction of s) made by two tangents at two points P and Q is Δθ, the direction change rate k is

[Equation 1]

This is called the curvature at point P of the curve. So the curvature of the curve y = f (x) is

[Equation 2]

And the inverse r = 1 / k of k is called the radius of curvature.

2 is a view showing a structure viewed from above the screen support 100 having a curvature according to an embodiment of the present invention.

2, in one embodiment of the present invention, the horizontal stage 120 has a curvature of a predetermined size, and the plurality of vertical stages 110 or other horizontal stages 120 disposed on the same horizontal axis. It can be characterized by bonding.

In this case, the vertical stage 110 may vary depending on the form of the theater such as an arrangement in which the left and right ends of the vertical stage are arranged in front of the straight line in a straight line (straight line), a curved line (round) or a straight line arrangement according to the shape of the theater wall. Can be arranged.

In addition, the horizontal stage 120 having a curvature of a predetermined size is bonded to the plurality of vertical stages 110 or a plurality of horizontal stages 120 arranged on the same horizontal axis, which is described below. It is bonded to the vertical stand 110 of the horizontal (120) to form a cross to form a base on which the speaker 20 can be mounted together. Accordingly, the speaker 20 may be mounted on a cross portion having a cross shape, or a stand for fixing the speaker may be installed to stably mount the speaker 20.

In addition, by making the curvature of the horizontal stage 120 the same as the curvature of the screen 10, the speaker 20 can be placed as close as possible to the screen. Therefore, the speaker 20 can be brought into close contact with the screen as much as possible according to the curvature of the screen, thereby effectively transmitting the sound effect to the viewer.

In addition, in an embodiment of the present invention, the horizontal stand 120 may be bonded to the plurality of vertical stands 110 at predetermined intervals in a direction parallel to one surface of the plurality of vertical stands 110. More specifically, the vertical poles 110 are arranged in two or more horizontal lines, the horizontal pole 120 may be bonded to a plurality of vertical poles 110 in the same row or the same row. In this structure, since the upper and lower sides become a ladder structure, the operator can easily move up and down without any tools, and thus the work is easy, and the lower part of the support becomes a structure in which the weight is evenly distributed so that the screen and Can mount the speaker.

In another embodiment of the present invention, the screen support 100 having a curvature further includes a pedestal provided on the ground to support the vertical pedestal 110, and the vertical pedestal 110 is bonded to the pedestal to face a predetermined direction. Can be. Thus, when the support for the vertical stand 110 is placed, it is possible to take a stable structure without having to set up several vertical stands 110, thereby taking a stable structure by utilizing a small space, and the pedestal and the vertical stand 110 are By adjusting the angle of bonding can be installed by placing the vertical stand 110 at an angle intended by the designer rather than necessarily in the vertical direction.

In addition, in another embodiment of the present invention, the horizontal stand 120 has an angle formed by a straight line and a vertical stand 110 connecting the other end of the horizontal stand at the top and the horizontal stand arranged at the same vertical stand 110 to 10 degrees. It may be characterized by forming a 20 to 20 degrees.

“Tilt” means an angle formed by a straight line connecting the first long axis member and the second long axis member of the frame to the vertical stand 110 of the support. As described above, the long axis member of the frame includes a first long axis member and a second long axis member that respectively mount the upper and lower ends of the screen. Since the screen frame having the curvature is tilted by joining with the other end of the horizontal support 120 of the support, a straight line and a vertical support connecting each other end of the horizontal support 120 disposed on the same vertical support 110 of the support ( An angle formed by 110 means a tilt of the screen 10 having a curvature. In addition, the vertical stand 110 is preferably arranged vertically from the ground bar, "tilt" is a straight line connecting the other end of the horizontal stage 120 disposed on the same vertical stand 110 and a straight line perpendicular to the ground It also means the angle to make up.

As described above, the reason for forming the curvature and the tilt on the screen by using the screen support 100 having the curvature of the present invention is as follows.

The curvature of the screen 10 gives a sense of immersion compared to a flat screen, but may cause problems such as sag of the screen and uneven brightness distribution of the screen according to the curvature of the frame.

Therefore, when the screen 10 having curvature is installed, a phenomenon in which some areas of the screen sag and a difference in brightness between the center and the corners of the screen occurs, which minimizes the above phenomenon and gives a new immersion to the viewer. The following experiment was conducted to find the optimal form.

First, a distance meter was installed at a distance of 10000 mm (10M) from the center of the wall on which the screen was installed, and the screen was divided into 16 equal parts as shown in FIG.

At this time, the difference between the optimal value from the point where the distance measuring device is installed to each area of the screen and the value measured by the actual distance measuring device was calculated. When the difference was more than ± 300mm, it was determined that the deflection occurred. When the deflection phenomenon occurs in a specific area, the area is again divided into 16 equal parts as shown in FIG. 8, the distance is measured again, and an area having a difference of ± 300 mm or more is calculated to confirm the degree of deflection more accurately.

Here, the optimal value is based on the measured distance after the screen is first installed, as shown in Table 1, and the difference that occurred when the distance was checked after one week by installing the tilt at 16 degrees, 24 degrees, and 30 degrees is shown in the table. It is as 2, Table 3, Table 4, and the unit of the measured distance is mm.

TABLE 1

TABLE 2

TABLE 3

TABLE 4

Referring to Tables 1 to 4, when the tilt is 24 degrees, some deflection occurs at the top of the center portion of the screen, and when the tilt is 30 degrees, the overall deflection occurs at the center portion of the screen. Confirmed.

Therefore, the degree of deflection was the smallest at 16 degrees. When the tilt was adjusted at 16 degrees, the degree of deflection rarely occurred when the angle was less than 20 degrees. there was. Therefore, when the tilt was 10 degrees to 20 degrees, it was confirmed that less sag occurred while maintaining immersion.

Then, the radius of curvature of the first long axis member: the second long axis member: the short axis member is 16: 1, 1, 1, 2: 2: 1: 0.8 and Case 3: 1: 1: 1.2, Case 4: 1: 1.2: 1, Case 5: 1: 1.2: 0.8, Case 6: 1: 1.2: 1.2, Case 7: 1: 1.2: 1.5 It was. Through the above test results, it was confirmed that the case where the ratio of the first long axis member and the second long axis member are the same (case 1 ~ case 3) is relatively less sag, while Case 2 maintains the highest immersion feeling. Less deflection occurred.

On the other hand, in order to check the ratio of the radius of curvature of the frame in which the difference in brightness between the center and the corner of the screen is the smallest, the screen is changed by varying the ratio of the radius of curvature of the frame while the tilt is set to 10 degrees to 20 degrees. The experiment was conducted by dividing the area into equal parts and measuring the brightness of the screen (the amount of light of a light source having a constant range divided by the area of the light source).

First, the test image (black image) from the projector was projected on the screen, and the brightness meter for each area was measured by installing a brightness meter 10M away from the center of the wall.

In general, the screen brightness at the center is brighter, and the darker the measurement is, the smaller the difference in brightness between the center point and the end point, and the more bright points make the image clearer and less heterogeneous. The score was evaluated.

Therefore, the score evaluated in the frame of each radius of curvature,

Evaluation score = 10 points-(standard deviation of luminance divided by 16).

The results of measuring the scores according to the brightness distribution by producing several frame curvatures are shown in Table 5, and the unit of measured luminance is fL.

TABLE 5

In addition, the results of visually expressing the brightness distribution of the screen based on the experimental scores may be understood as shown in Table 6 and the brightness distribution.

TABLE 6

Referring to Table 5, the radius of curvature of the first long axis member: second long axis member: short axis member having a score of 8 or more points is 8000: 8000: 8000 (8.6 points), 10000: 10000: 8000 (9.2 points), 15,000. : 15,000: 8000 (9.1 points), 15,000: 15,000: 10,000 (9.2 points), and 15,000: 15,000: 15,000 (8.2 points). In summary, the brightness distribution is the most even in the range of 1: 1: 0.6 ~ 1.0.

Therefore, when installing a screen having a curvature, while installing the tilt from 10 to 20 degrees, the curvature ratio 1: 1: 0.6 ~ 1.0 through the experimental results, the screen sagging phenomenon and the center and corners of the screen It was confirmed that the phenomenon of brightness difference could be solved.

Therefore, when the tilt and curvature were adjusted by producing various ratios as in the above experiment, when the ratio was 1: 1: 0.6 ~ 1.0 and the tilt was 10 degrees to 20 degrees, the screen brightness was evenly distributed without almost sagging. There is an effect that can give the viewer maximum immersion. In particular, when projecting an image onto a screen 10 having a curvature radius ratio of 1: 1: 0.8 and a tilt of 16 degrees, such as a ratio of 10000: 10000: 8000 (9.2 points), the characteristics of the screen with curvature Due to the difference in the distance the image is projected from the projection apparatus to the screen, it can be seen that 2D movies have the same effect as 3D movies, and 3D movies have a much higher dynamic effect than flat screens.

It may further include a diagonal 140 forming an angle of 10 to 20 degrees with the 110 and a beam 140 vertically bonded to the adjacent diagonal 130. At this time, the wall surface means the wall surface on which the screen is to be installed in the theater.
