The present invention relates to an image output device that expresses a three-dimensional effect by rotating a transparent display. In more detail, the transparent display is installed in a chamber, and the transparent display is installed in a plurality of sets in the height direction of the chamber and rotated to create more colorful and diverse images. The aim is to provide an image output device capable of expressing three-dimensional images.

A video output device provides the ability to output images or videos through a screen, and video output devices with quite a variety of types and functions are currently being released.

Among these, the holographic image output device provides the function of creating a three-dimensional image as if the image is floating in space by projecting the image in a specific space and performing reflection processing using a mirror.

However, although these holographic image output devices reproduce three-dimensional images, they have the disadvantage of lower resolution of the images themselves compared to flat displays that currently boast high resolution.

The layered-type volumetric display system using multiple LED bars, which is domestically registered patent number 2270468, is a first LED matrix panel, a motor that rotates the first LED matrix panel, and a screen at a corresponding viewpoint adaptively according to the rotation state of the motor. It has been disclosed that 3D content expression that maximizes the sense of volume is possible with a volumetric light field display system using LED matrix panels composed of LED bars, including a playback device that displays on the first LED matrix panel.

However, according to the above technology, not only is the image relatively monotonous because only one single plane is provided when the LED bar is rotated, but the volume of the matrix panel including the LED bar must be increased to output an image with a corresponding size, so the image of the matrix panel There may be a burden of having to be large in volume.

Therefore, there is a need to develop a new and advanced image output device that has a relatively small display volume and can output more colorful and dynamic three-dimensional images by providing multiple rotation planes and making the display itself transparent. It is a situation that is emerging.

Domestic registered patent No. 2270468

The present invention was developed to overcome the problems of the above technology. By placing a transparent display in the space within the chamber, the height of the chamber is provided with a basis for outputting a three-dimensional image as if floating in space. The main purpose is to provide an image output device that can output more colorful and dynamic images by arranging a plurality of transparent displays at regular intervals along and then rotating them.

Another object of the present invention is to provide an environment in which more diverse three-dimensional images can be displayed by adjusting the curvature or installation position of the transparent display installed on the center bar.

Another purpose of the present invention is to provide versatility by installing a screen around the chamber and outputting separate images from the screen so that two images can be displayed to the viewer simultaneously.

A further object of the present invention is to perform a special surface treatment on the transparent window of the chamber to prevent the problem of the image on the transparent display being obscured by glare due to the image on the screen.

In order to achieve the above object, an image output device that expresses a three-dimensional effect by rotating a transparent display according to the present invention includes a chamber surrounding an internal space with a transparent window; a center bar extending from the center of the interior space along the height direction of the chamber; It is installed in plural pieces at regular intervals along the height direction of the center bar, and includes a rotating part including a motor, and a plurality of pieces radially based on the center of the rotating part. It is transparent and outputs an image while rotating by driving the rotating part. A video output unit including a display; and a controller that controls image output through the transparent display by reflecting the rotational speed of the rotating unit on a circular plane generated when the transparent display rotates.

In addition, the image output device includes a screen installed on a wall spaced a certain distance away from the chamber, and a beam projector that outputs a sub-image separate from the image on the screen.

In addition, the area of the transparent window facing the screen is characterized by being coated with an anti-glare functional agent containing porous amorphous silica and Myristoyl Lactylic Acid.

According to the image output device that expresses a three-dimensional effect by rotating a transparent display according to the present invention,

1) It has the advantage of being able to create a more dynamic and colorful three-dimensional image by rotating the transparent display in a plurality at a certain distance in the height direction.

2) The image expression technique can be expanded by varying the shape and installation location of the transparent display.

3) By outputting separate images on the screen simultaneously with images on the transparent display, it is possible to create a more diverse and colorful image output environment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.

Figure 1 is a perspective view showing the schematic structure of the video output device of the present invention.

The video output device of the present invention has a plurality of video output units 300 installed via the center bar 200 installed in the chamber 100, and the output state of the video output from the video output unit 300 through a controller. By controlling , referring to FIG. 1, it can be seen that an image is output within the chamber 100 having a cylindrical shape.

Specifically, the image output device of the present invention is based on including a chamber 100, a center bar 200, an image output unit 300, and a controller.

The chamber 100 is a structure having an internal space and a volume surrounding the internal space with a transparent window 110. In Figure 1, the chamber 100 has a cylindrical shape to double the effect of viewing images from various directions. It is shown.

However, it is not necessarily limited to a cylindrical shape and may have various shapes such as a hexahedral shape. However, as described above, in order to maximize the function of viewing images from various directions, the chamber 100 has a cylindrical shape as shown in FIG. 1. It is desirable to consist of

This chamber 100 can also be seated on the pedestal 120 placed on the floor. Although not shown in the drawing, there is an axis protruding in the vertical direction (height direction of the chamber 100) from the center of the pedestal 120 and this axis. It is also possible to further enhance the three-dimensional image output effect by connecting the chamber 100 to a rotation means including a motor that rotates electrically so that the chamber 100 can rotate about its axis.

The transparent window 110 is made of a transparent material to ensure the visibility of the image output from the image output unit 300, and provides the basic function of protecting the image output unit 300 and, as will be described later, a beam projector ( By reflecting the image additionally output from 400), it is possible to create a production effect as if a holographic image is output from the central part of the chamber 100.

The center bar 200 has a pillar-like structure extending along the height direction from the center of the chamber 100, and provides a physical space to support the image output unit 300, which will be described later, as well as image output. It provides a space for the cable that processes the power and image data transmitted to the unit 300 to pass through, providing a neat appearance.

In the drawing, the center bar 200 is shown as having a dark color, but it is not limited to this and can also be made of a transparent material like the transparent window 110, thereby maximizing the effect of displaying the image as if it were floating in the air. there is.

The image output unit 300 is installed in plural pieces (three in the drawing) at regular intervals along the height direction of the center bar 200, and specifically includes a rotating unit 310 and a transparent display 320. ) includes.

The rotating unit 310 includes a motor and provides the function of rotating the rotating shaft 311 by driving the motor. At this time, the driving of the motor (whether the motor is driven and the rotational speed of the rotating shaft 311, etc.) is controlled by a controller to be described later. You can control it.

In addition, a disk-shaped rotating plate 312 with a certain diameter and area may be installed at the end of the rotating shaft 311, and the transparent display 320, which will be described later, can be easily rotated from the rotating unit 310 through this rotating plate 312. It can provide a base that can be more stably attached/fixed without falling off.

Figure 2 is a front view showing an example in which the transparent display of the present invention rotates to form a circular plane.

The transparent display 320 is provided in a plurality radially based on the center of the rotating unit 310 (for example, the rotating plate 312), and provides a function of outputting an image while rotating by driving the rotating unit 310.

This transparent display 320 refers to a device that outputs an image or video from the display panel (display in a narrow sense) while transmitting light while the display panel (display in a narrow sense) is transparent.

This transparent display 320 initially started out as a transparent LCD, but due to the presence of a backlight on the back of the display panel as well as the nature of the LCD requiring a polarizer and a color filter, there was a problem with light transmittance being only 10%, so transparent OLED is currently popular. It is being developed well.

Transparent OLED, unlike LCD, has the characteristic of emitting light on its own, so it can adopt transparent materials on both sides except for the part that expresses color in the absence of components such as a backlight, and also applies the principle of becoming transparent by thinning the metal substrate. It has exceptionally excellent light transmittance.

The transparent display 320 of the present invention is preferably made of transparent OLED, but is not necessarily limited thereto, and can be understood as a concept including a display including various transparent elements that will be developed in the future.

At this time, the multiple transparent displays 320 mounted on one rotating unit 310 can be formed in a rectangular parallelepiped shape with a width narrower than the length as shown in FIG. 1, and can also be formed in a fan-shaped shape specialized for the radial arrangement structure. do.

At this time, two to four transparent displays 320 can be mounted on one rotating part 310.

This transparent display 320 rotates with the rotation of the rotating part 310 to draw a virtual plane, that is, a circular plane. This circular plane creates an optical illusion as if floating in the air due to the transparent nature of the transparent display 320. can be provided.

In addition, the transparent display 320 can be manufactured in a flat (flat) shape, as well as curved as shown in FIG. 1, and this curved configuration will be described in detail below.

In addition, the transparent displays 320 are installed one per rotating unit instead of two or four, and are divided into an area where an image is displayed (active area) and an area where an image is not displayed (inactive area) and rotated, as if radial. It is also possible to provide an optical illusion as if multiple units were installed.

The controller provides a function to control image output through the transparent display 320 by reflecting the rotation speed of the rotating unit 310 on the circular plane generated when the transparent display 320 rotates.

That is, when the controller outputs an image from the transparent display 320, it performs an image output control function that allows the image to be viewed as three-dimensional as possible. Reflecting the rotation speed of the rotating part 310 means that the transparent display 320 By adjusting the rotation speed of the rotating part 310 to the minimum that the viewer can feel as a three-dimensional image by the afterimage generated while rotating, a selected image that can feel a three-dimensional effect can be output, and further, the image can be displayed according to the rotation speed. This means that you can even set the blinking timing.

At this time, it is more preferable to set the rotation speed of the rotating unit 310 to rotate at 25 to 35 RPS (Revolutions Per Second) or more in 2 to 3 seconds to create a three-dimensional effect of the image, and the controller operates the motor of the rotating unit 310 It can be controlled to implement the above-described rotation speed.

At this time, the faster the rotation speed of the rotating part 310, the more the optical illusion effect, as if the image is protruding forward, can be doubled.

In addition, the controller has the function of linking the image database in which images are stored with a separate image server to select and output a specific image from the image database.

In addition, in the process of outputting an image, the controller programs the time and cycle for outputting an image from a specific pixel of the transparent display 320 in conjunction with the rotation speed of the rotating unit 310, and then programs the time and cycle for outputting the image to a specific pixel according to the programmed time and cycle. The signal can be processed so that the image blinks in units.

At this time, of course, the above-described programming processing can be performed in conjunction with information about the number and position of the detailed transparent displays 320 installed on each rotating unit 310.

These controllers include RAM (Random Access Memory, not shown) and ROM (Read-Only Memory, not shown) that temporarily and/or permanently store signals (or data) processed internally via a board. , may include a processor.

At this time, the processor may include one or more cores (not shown), a graphics processing unit (not shown), and/or a connection path (e.g., bus, etc.) for transmitting and receiving signals with other components.

Programs (one or more instructions) for execution and control of various sub-configurations, which will be described later, can be stored in the memory. Programs stored in memory may be divided into a plurality of modules according to their functions.

The functions and operations of the video output device of the present invention according to this configuration are described as follows.

Figure 3 is a conceptual diagram illustrating a state in which an image is output on a transparent display.

Referring to FIG. 3, when the rotating unit 310 rotates, the transparent display 320 forms a circular plane in the space within the chamber 100, and the viewer can visually confirm that an image is output in this circular plane.

That is, not only can the transparent nature of the transparent display 320 create a holographic effect as if the image is floating in the air, but also the transparent display 320 outputs the image while rotating, so the image blinks depending on the rotation speed. By adding functions, it is possible to create more dynamic and dynamic visual effects.

In addition, since the image output unit 300 is installed at a certain distance along the height direction of the center bar 200, a plurality of circular planes generated when the transparent display 320 is rotated are also implemented, so that each plane has a separate You can create an environment where you can set various visual effects, such as through visual processing or integrated processing.

In summary, the image output device of the present invention only outputs a flat shape even when the known LED is rotated in a programmed state, but by applying the transparent display 320, the transparent display 320 itself appears as if in the air. In addition to providing a basic three-dimensional effect by providing a floating state, the transparent display 320 can rotate and output images using various techniques, providing the characteristic of realizing a more dynamic and dynamic image output effect.

Figure 4 is a conceptual diagram showing a modified example of a transparent display and a rotating part.

Referring to FIG. 4, it can be seen that the transparent display 320 does not only have a flat shape, but can also have a certain curvature and a rounded structure when bent in a specific direction, specifically when a transparent flexible display is applied. .

According to this structure, when the transparent display 320 rotates, it not only implements a circular flat shape, but also forms a three-dimensional image output space with a sense of perspective such as a funnel or dome shape, thereby outputting an image with a more convincing three-dimensional effect when outputting the image. It can provide a foundation for doing so.

Furthermore, as will be described later, when additional images are output from a separately installed beam projector 400, these additional images can be processed to be reflected according to the numerical settings of the bending direction and curvature, providing a mirror-like function in a holographic imaging device. As it is implemented, it can be equipped with the ability to create more realistic hologram images.

In addition, the plurality of rotating parts 310 are not only installed uniformly along a straight line extending from the center bar 200, but also an imaginary line extending in the height direction from one side of the center bar 200 as shown in FIG. It can be installed so as to deviate from, for example, installed in a zigzag manner on the above-mentioned virtual line.

According to this, the circular shape created as the transparent display 320 rotates does not draw one same plane, but forms a plurality of planes with different angles, creating a much more dynamic effect through a geometric and grotesque three-dimensional space. It is possible to lay the foundation for outputting three-dimensional images.

Additionally, referring again to FIG. 3, it can be seen that the beam projector 400 is installed at the top of the center bar 200.

This beam projector 400 provides a function of outputting a so-called 'additional image' toward at least one of the plurality of transparent displays 320.

These additional images are stored in an image database linked to the controller. In particular, they have a screen configuration or property that can be linked to the above-described images, so the images are output from the transparent display 320 and at the same time, the beam projector 400 displays additional images. You can control the video output from the controller to output it.

This beam projector 400 may reflect a portion of the additional image from the transparent window 110 or the transparent display 320 to implement an image similar to a hologram along with the image in the space within the chamber 100.

In other words, the beam projector (in particular, the amount of reflection may be doubled in the transparent window 110 or the transparent display 320 (particularly in the transparent display 320 that is curved and rounded) even without mirror processing like a holographic imaging device. A portion of the additional image output from 400) may be reflected, and this reflected additional image may form an image on the screen of the transparent display 320 or overlap with the image output from the transparent display 320 itself to create various image implementation effects. An environment that can be expressed can be built.

In other words, it is possible for the additional image to provide a function that can assist the image output from the transparent display 320 or be used as a background, while providing a basis for implementing more diverse and diverse visual effects.

Figure 5 is a conceptual diagram illustrating a state in which a sub-image is output on a screen installed around the chamber.

As can be seen from Figure 5, the image output device of the present invention includes a screen installed on a wall spaced a certain distance away from the chamber 100, and a sub-image that is separate from the image output from the transparent display 320 on this screen. It is possible to include a beam projector 400.

At this time, the controller also links with the image database that stores the sub-image, sets and matches the visual relationship between the image output from the transparent display 320 and the sub-image, then stores them together in the image database and controls their output simultaneously. possible.

That is, the embodiment of FIG. 5 expresses that a more dynamic visual environment can be implemented through the combination of the sub-image output from the beam projector 400 and the image output from the transparent display 320. For example, the image and The sub video can perform the same role as the main video/background video.

In addition, it is possible to perform a variety of visual expressions with interconnected themes by outputting the shape of a specific model in the sub video and outputting sneakers worn by the specific model or separate motions taken by the model in the video.

In the embodiment of FIG. 5, the image output device of the present invention may additionally include an illuminance measurement sensor 500 that measures the illuminance of the sub-image while installed on one side of the chamber 100 facing the screen.

In response to this, the controller may include a function to differentially adjust the rotation speed of the rotating unit 310 according to the height and low of the illuminance measured by the illuminance measurement sensor 500.

For example, when the illuminance of the sub-image is high and the image output from the transparent display 320 is difficult to see, the controller increases the rotation speed of the rotating part 310 so that the image stands out toward the front, making the transparent display 320 visible to the viewer. The video can be processed to make it more visible.

Conversely, when the illuminance of the sub-image is low, the controller can maintain the rotation speed of the rotating unit 310 at a constant speed or lower it so that the sub-image and the image appear more harmoniously.

In the above-mentioned example, an additional material can be provided that effectively prevents the sub-image from preventing the viewer from seeing the image of the main display or further causing glare.

Specifically, it is possible to coat the area of the transparent window 110 facing the screen with an anti-glare functional agent.

The anti-glare functional agent includes porous amorphous silica, where the porous amorphous silica exhibits an amorphous structure without regularity and an irregularly connected three-dimensional network structure.

This porous amorphous silica is easy to disperse and can be evenly coated on the surface. It does not cause turbidity and has excellent transparency, so it can evenly disperse the light from the sub-image irradiated through the transparent window 110, and has a porous structure on the surface. An effect that prevents glare, that is, light reflection, so that light is naturally spread and provided, and at the same time, prevents unnecessary light reflection in the transparent window 110, thereby reducing glare that viewers may feel. provides.

In addition, myristoylactylic acid functions as a dispersant and emulsifier. In particular, it maximizes the dispersibility of the above-mentioned porous amorphous silica and forms a more uniform coating film on the surface of the transparent window 110.

Therefore, according to the anti-glare functional agent containing the above-mentioned composition, the image of the transparent display 320 can be viewed clearly while preventing the problem of the image of the transparent display 320 being difficult to see or causing glare due to light flowing in from the screen. It is possible to process it so that it can be processed.

In addition, this anti-glare functional agent may contain additional components in addition to porous amorphous silica. The steps for manufacturing this anti-glare functional agent are described with drawings as follows.

Figure 6 is a flowchart showing the steps for manufacturing the anti-glare functional agent contained in the injection liquid.

Referring to FIG. 6, the anti-glare functional agent of the present invention includes the steps of preparing the first material (S11), preparing the second material (S12), and completing the anti-glare functional agent (S13). It can be manufactured through

(S11) Preparing the first material

First, a first material is prepared by mixing 10 to 20 parts by weight of porous amorphous silica, 1 to 10 parts by weight of Myristoyl Lactylic Acid, and 65 to 90 parts by weight of purified water.

As described above, porous amorphous silica is a material that enhances the anti-glare effect and increases the surface rigidity of the transparent window 110 without impairing transparency, and purified water is added as a dispersion medium for the porous amorphous silica.

At this time, the porous amorphous silica has high dispersibility, but in order to form a more even dispersion, myristoylactylic acid, which functions as a dispersant and emulsifier, is added as described above to maximize the dispersibility of the porous amorphous silica and to form a more even dispersion. This allows a more even coating to be formed on the surface.

(S12) Preparing the second material

Next, a second material is prepared by mixing 85 to 95 parts by weight of the first material, 1 to 10 parts by weight of zinc carbonate, and 3 to 10 parts by weight of Mannan.

Zinc carbonate is a substance that combines with the pores formed in porous amorphous silica to enhance the surface coating effect and at the same time makes the surface more irregular to strengthen the anti-glare effect.

Mannan is a natural polysaccharide composed of a polymer of mannose, and functions as a film forming agent to improve coating properties and adhesion to the surface of the transparent window 110.

(S13) Steps to complete the anti-glare function

Finally, 90 to 95 parts by weight of the second material are mixed with 1 to 5 parts by weight of Behenalkonium Chloride and 1 to 3 parts by weight of Glucose Pentaacetate to complete the anti-glare functional agent.

Behenalkonium chloride is an antistatic agent and is added to prevent static electricity generation on the surface of the transparent window 110, and glucose pentaacetate is an emulsion stabilizer to promote emulsification and dispersion of the components included in the anti-glare functional agent. It can be understood that SMS was added for this purpose.

According to the anti-glare functional agent of the present invention, not only can the anti-glare function on the surface of the transparent window 110 be strengthened, but it can also be coated more firmly, and further prevent the generation of static electricity on the surface. Provides effect.

Table 1 is a table showing the experimental results. Transmittance pencil hardness Anti-glare properties Example 94% 4H 4.8% Comparative example 92.8% 3H 7.9%

As shown in Table 1 above, the Examples of the present invention have high transmittance and excellent anti-glare characteristics when compared to the Comparative Examples, and furthermore, it can be confirmed that the hardness is high, so it can be confirmed that the overall physical properties are excellent.
