Description

Technical Field

[0001] The present invention relates to a display device, and more particularly, to a display device that manages and displays goods stored therein. Background Art

[0002] Only when the shoes are properly stored, the shoes can be worn for a long time without damaging the shape of the shoes. When the shoes are stacked layer by layer, the shape may be deformed. Generally speaking, shoe cabinets are used to organize and store shoes.

[0003] In recent years, people who collect popular brand shoes have emerged as a hobby or as part of financial technology, and display devices configured to store and display shoes have been announced.

[0004] U.S. Patent Unexamined Publication No. 2018-0127150 (hereinafter referred to as "existing document 1") discloses a "modular storage container", and the modular storage container includes a shell, a door panel, a fan and a light source.

[0005] According to the above-mentioned prior art document 1, the housing has a rectangular parallelepiped box shape having an opening on its front surface. There is a storage space in the housing. The door panel opens / closes the opening of the housing and is configured to be transparent or translucent.

[0006] In the above-mentioned prior art document 1, a fan is mounted on the rear panel of the housing. When the fan rotates, the air in the accommodation space is ventilated to the outside air. An air duct is formed in the housing for air flow between the outside air and the accommodation space. A light source is mounted in the upper panel and illuminates the accommodation space.

[0007] According to the above-mentioned prior art document 1, since the internal air of the container is configured to be ventilated to the outside air, the possibility that the internal environment (temperature and humidity) of the container will be affected by the external environment (temperature or humidity) of the container increases. That is, it may be difficult to control the internal temperature and humidity of the container.

[0008] For example, according to the above-mentioned prior art document 1, since the internal air of the container is ventilated only to the outside air, when the humidity of the outside air is high as in the rainy season, the humidity of the accommodation space can be continuously maintained. The air may change the color and shape of the shoes stored in the container, and cause the shoes to be contaminated by mold and bacteria that are easy to breed under high temperature and high humidity.

[0009] Therefore, since the above-mentioned prior art document 1 does not consider a technique for maintaining the internal temperature and humidity of the container in an optimal state, there is a risk of deformation or contamination of the shoes during use of the container by the user.

[0010] Furthermore, according to the above-mentioned prior art document 1, the interior of the container can be viewed only through the door panel, and the interior of the container cannot be viewed at the left or right side of the container, so there is a limitation in increasing the display effect of the shoes.

[0011] Regarding the technology of displaying shoes for commercial purposes, Korean Patent Unexamined Publication No. 2013-0034367 (hereinafter referred to as "existing document 2") discloses a display device having a transmissive display with a transparent display, and the resulting display device is configured to include a display device body, a transparent display device, a turntable, a touch panel and an LED.

[0012] The display device body has a space in which products such as shoes can be stored. A transparent display device is installed on the front surface of the display device body. The product is placed on a turntable and rotates inside the display device body by the rotation of the turntable. The LED illuminates the product inside the display device body.

[0013] However, since the above-mentioned prior art document 2 does not consider a technique for controlling the internal temperature and humidity of the display device, there is a risk of deformation or contamination of the shoes while the shoes are stored inside the display device.

[0014] Furthermore, according to the above-mentioned prior art document 2, the interior of the display device can be observed only through the transparent display device, and the interior of the display device cannot be observed at the left or right side of the display device, so there is a limitation in improving the display effect of shoes.

[0015] Korean Patent Unexamined Publication No. 10-20000-0009653 (hereinafter referred to as "existing document 3") discloses a "shoe cabinet for disinfection", and the resulting shoe cabinet is configured to include a main body, an infrared irradiation unit, a circulation fan, an air circulation passage, a disinfection filter unit, and the like.

[0016] The above existing document 3 discloses dehumidifying, disinfecting and deodorizing shoes by far infrared rays and filters while storing the shoes.

[0017] However, according to the above-mentioned prior art document 3, the shoes cannot be displayed.

[0018] As described above, conventional devices in which shoes are housed have limitations in terms of shoe care and shoe display.

[0019] As a result, in the development of a shoe care device, the following aspects need to be considered: whether the display effect of the shoes can be maximized while continuously maintaining the environment of the internal space of the shoe care device (hereinafter referred to as the "accommodating space"); whether the accommodation space can be easily opened and closed; whether the shoes can be effectively stored and taken out when the accommodation space is opened; whether the structural stability of the shoe care device can be ensured when the accommodation space is opened to the maximum extent, etc.

[0020] In addition, the following aspects should also be considered: even if the shoe care device is stacked into multiple layers, whether the structural rigidity of the lowest shoe care device can be maintained for a longer period of time; whether the electrical stability can be effectively guaranteed even if the shoe care device is used for a long period of time; whether the internal effect of the shoe care device can be maximized in addition to the display effect of the shoe; whether the internal components are properly arranged in a limited space; whether the convenience of use is excellent, etc., and all points need to be taken into consideration to develop the shoe care device. Summary of the invention

[0064] Hereinafter, the embodiments disclosed in this specification will be described in detail with reference to the accompanying drawings, and the same or similar parts are represented by the same or similar reference numerals, and their repeated description will be omitted. The suffixes "module" and "unit" for the parts used in the following description are given or mixed only in consideration of the easy preparation of the present invention, and do not have their own distinguishing meanings or functions. In addition, in describing the embodiments disclosed in this specification, if it is determined that the detailed description makes the key points of the embodiments disclosed in this specification unclear, the detailed description of the related known technologies will be omitted. In addition, it should be understood that the drawings are only used to easily understand the embodiments disclosed in this specification, and the technical spirit disclosed in this specification is not limited by the drawings, and includes all changes, equivalents or substitutes included in the spirit and technical scope of the present invention.

[0065] Terms including general numbers such as first and second are used to describe various elements, but the elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0066] It should be understood that when describing that a component is “connected to” or “close to” another component, the component may be directly connected to or close to the other component, or a third component may exist between them. On the contrary, when describing that a component is “directly connected to” or “directly close to” another component, it should be understood that there is no component between the component and the other component.

[0067] Singular forms include plural forms unless the context clearly indicates otherwise.

[0068] In the present application, it should be understood that the term "including" or "having" means the presence of the features, quantities, steps, operations, components, parts or combinations thereof described in the present specification, but does not preclude the possibility of the presence or addition of one or more other features, quantities, steps, operations, components, parts or combinations thereof.

[0069] The present invention discloses a display device 1. The display device 1 is configured to display objects while accommodating the objects therein. The display device 1 may be configured to manage the objects so as to maintain the physical / chemical state of the objects accommodated therein.

[0070] The objects described in the present disclosure may include one or more of shoes, wallets, bags, dolls, toys, plastic models, accessories, and souvenirs. That is, the display device 1 may be configured to display and manage one or more of shoes, wallets, bags, dolls, toys, plastic models, accessories, and souvenirs.

[0071] The display device described in the present disclosure may be a device for displaying and managing shoes among objects.

[0072] The display device described in the present disclosure may be an apparatus that displays and manages objects other than shoes.

[0073] The following description will be based on shoes as an example of an object to be displayed and managed. The shoes described in the present disclosure may be replaced with objects other than shoes.

[0074] When the display apparatus described in the present disclosure is intended to display and manage shoes, the display apparatus may be referred to as a shoe care device.

[0075] When the shoe is directly exposed to dirt, water, heat and / or sunlight, the fiber material of the shoe may deteriorate over time and the color and shape of the shoe may change.

[0076] In order to preserve the shoes for a long time in the original state (e.g., the state of the shoes when purchased or the state of clean shoes), the shoes should not be exposed to light too much, and the shoes should be stored in a place that is not too cold or too hot. In addition, the shoes need to be stored in a place where the temperature and humidity are properly maintained.

[0077] Since shoes made of leather or suede materials are easily discolored or have mold, the shoes should be stored in an environment where temperature and humidity are properly maintained. Mothballs obtained by solidifying insecticides and spices have a unique chemical odor that makes it difficult to remove because the odor penetrates into the shoes when the mothballs are stored with the shoes.

[0078] Furthermore, when shoes are stacked layer by layer, the shape of the shoe may change due to the applied load.

[0079] Meanwhile, as described above, in recent years, the number of users who collect popular brand shoes as a hobby or as part of fintech has increased, and shoe care and shoe display have become important needs of users.

[0080] Taking these points into consideration, the display device according to an embodiment of the present invention is configured to: safely store shoes, establish and adjust the environment required for each shoe (e.g., a predetermined range of temperature, humidity, etc.), and effectively display shoes and improve user convenience.

[0081] The first direction X, the second direction Y, and the third direction Z described in the embodiment of the present invention may be directions orthogonal to each other.

[0082] The first direction X and the second direction Y may be directions parallel to the horizontal direction, and the third direction Z may be a direction parallel to the vertical direction. When the first direction X is a direction parallel to the front-rear direction, the second direction Y may be a direction parallel to the left-right direction.

[0083] In describing the embodiments of the present invention, except for the case where they are particularly differently restricted, the first direction X, the second direction Y, and the third direction Z may be understood as a front direction, a left direction, and an upper direction, respectively.

[0084] Figure 1a is a perspective view showing a display device 1 according to an embodiment of the present invention. Figure 1a A state in which the inner space of the display device 1 (hereinafter referred to as “accommodating space 10 ”) is closed is shown. Figure 1b is shown where the shoes S are stored Figure 1a A three-dimensional diagram showing the state of the display device 1 in the receiving space 10.

[0085] Figure 2a It shows that Figure 1a A three-dimensional diagram of the display device 1 in a state where the receiving space 10 is opened. Figure 2b is shown looking in another direction Figure 2a A perspective view of a display device.

[0086] like Figure 1a and Figure 1b As shown in , the display device 1 according to the present embodiment is configured to include a main body 100 and a moving body 200 .

[0087] The main body 100 and the moving body 200 together form an accommodation space 10 for accommodating the shoes S. The main body 100 and the moving body 200 are coupled to move relative to each other. The moving body 200 may be coupled to the main body 100 to reciprocate in a horizontal direction.

[0088] Figure 1a The display device 1 shown in FIG. 1 can be Figure 2a That is, the mobile body 200 can be slidably moved relative to the main body 100 in the first direction X, and the display device 1 is changed from the closed state to the open state, so that the receiving space 10 can be opened.

[0089] Figure 2a The display device 1 shown in FIG. 1 can be again Figure 1a That is, the mobile body 200 can be slidably moved relative to the main body 100 in a direction opposite to the first direction X, and the display device 1 is transformed from the open state to the closed state, so that the receiving space 10 can be closed.

[0090] Therefore, in the presentation apparatus 1 according to the embodiment of the present invention, the moving body 200 may move in the first direction X or a direction opposite to the first direction X relative to the body 100 and reciprocate in the front-rear direction.

[0091] In a state in which the accommodation space 10 is closed, the accommodation space 10 may be sealed from the outside air. Therefore, when the shoes S are accommodated in the accommodation space 10 and the accommodation space 10 is closed, the contact of the shoes S with dust and moisture of the outside air may be interrupted.

[0092] The body 100 may form an upper surface and a rear surface of the receiving space 10 .

[0093] The moving body 200 may form a front surface, a lower surface, and both side surfaces of the receiving space 10 .

[0094] The accommodation space 10 may be formed in a hexahedral form. However, the accommodation space 10 of the display apparatus 1 according to the embodiment of the present invention is not limited to this shape, and may be configured in various three-dimensional shapes.

[0095] The main body 100 and the mobile body 200 may form an overall appearance of the display device 1. The appearance of the display device 1 may be configured in a hexahedron form. That is, in a state in which the main body 100 and the mobile body 200 are coupled to each other and the accommodation space 10 is closed, the appearance of the display device 1 may be configured in a hexahedron form. However, the display device 1 according to an embodiment of the present invention is not limited to such a shape, but may be configured in various three-dimensional shapes.

[0096] The body 100 may include an upper body 130 , a middle body 120 , and a lower body 110 .

[0097] The upper body 130 is positioned at the upper side of the accommodation space 10. The upper body 130 forms the upper surface of the accommodation space 10. The upper body 130 may form the uppermost portion of the display device 1. The upper surface of the upper body 130 may form a flat surface along a substantially horizontal surface. When a plurality of display devices 1 are provided, any one display device may be placed on the upper surface of the upper body 130 of another display device 1, and the display devices 1 may be stacked on each other.

[0098] The lower body 110 is positioned below the accommodation space 10. The lower body 110 may form the lowermost portion of the display device 1. The lower body 110 may form a bottom portion of the display device 1.

[0099] The middle body 120 is positioned behind the accommodation space 10. The middle body 120 forms a rear surface of the accommodation space 10. The middle body 120 may connect the upper body 130 and the lower body 110 behind the accommodation space 10. The middle body 120 may form a rear wall surface of the display device 1.

[0100] The body 100 is configured to include an upper body 130 , a middle body 120 , and a lower body 110 , and as a result, the body 100 may form a substantially 'C' form in a side view.

[0101] As described above, the mobile body 200 is configured to move forward and backward relative to the main body 100. The mobile body 200 may include a base 220, a transparent window 210, and a turntable 230.

[0102] The base 220 may be coupled to the lower body 110 to be slidably movable in the first direction X. The base 220 may form a bottom portion of the mobile body 200. The base 220 may be positioned at an upper side of the lower body 110. A bottom surface of the base 220 may be positioned in close contact with an upper surface of the lower body 110 or positioned near an upper surface of the lower body 110.

[0103] The transparent window 210 may be formed to extend upward from the base 220. The transparent window 210 may form a front surface and two side surfaces (left and right surfaces) of the accommodating space 10. The transparent window 210 may be made of a transparent or translucent material.

[0104] Light inside and outside the accommodation space 10 can pass through the transparent window 210. The transparent window 210 can be made of a weather-resistant material to prevent discoloration. The transparent window 210 can be made of a polymethyl methacrylate (PMMA) material that is weather-resistant and scratch-resistant.

[0105] The transparent window 210 can prevent a light beam having a predetermined wavelength from being introduced into the accommodation space 10. As an example, the transparent window 210 can be configured to block ultraviolet rays. Ultraviolet rays, which are electromagnetic waves corresponding to wavelengths of 10nm to 397nm shorter than visible light, are light that has a strong chemical effect and causes sunburn or discoloration.

[0106] As an example, an ultraviolet blocking film may be attached to the inner surface or the outer surface of the transparent window 210. Alternatively, the inner surface or the outer surface of the transparent window 210 may be UV-coated with an ultraviolet blocking agent.

[0107] The transparent window 210 includes a first window 211, a second window 212, and a third window 213. The first window 211 may form a front surface of the receiving space 10. The second window 212 may form a left surface of the receiving space 10. The third window 213 may form a right surface of the receiving space 10.

[0108] In a state in which the shoes S are accommodated in the accommodation space 10, the user can observe the shoes S through the transparent window 210. As a result, the display apparatus 1 can be used as a device that can display the shoes S while storing and caring for the shoes S.

[0109] like Figure 1a and Figure 1bAs shown in , in a state where the mobile body 200 is relatively positioned at the rearmost side, the accommodation space 10 can be sealed from the outside air. In this case, the accommodation space 10 can be formed in a hexahedral form. In this case, the mobile body 200 can be present at the first position, and the display device 1 is in a closed state.

[0110] like Figure 2a and Figure 2b As shown in FIG, the accommodating space 10 may be opened in a state in which the mobile body 200 moves along the first direction X. In this case, the upper portion of the first window 211 is spaced apart from the front surface of the upper body 130 toward the front side in the first direction X to form a gap (hereinafter referred to as a "first gap").

[0111] In this case, the second window 212 is spaced apart from the left side surface of the middle body 120 toward the front side in the first direction X to form a gap (hereinafter referred to as a "second gap"). The third window 213 is spaced apart from the right side surface of the middle body 120 toward the front side in the first direction X to form a gap (hereinafter referred to as a "third gap").

[0112] In a state where the mobile body 200 moves as much as possible in the first direction X, that is, in a state where the mobile body 200 is relatively located at the frontmost side, the mobile body 200 may exist at the second position and the display apparatus 1 may be in the open state.

[0113] The user may put the shoe S into the accommodation space 10 or take the shoe S out of the accommodation space 10 through the first gap. The inner panel 500 may be coupled to the inner surface of the middle body 120 or may be separated from the inner surface of the middle body 120.

[0114] The turntable 230 may form an upper surface on which the shoes S are placed. The upper surface of the turntable 230 may have a circular shape. The turntable 230 may form a lower surface of the accommodation space 10 together with the base 220 .

[0115] The turntable 230 may be rotatably coupled to the base 220 about a vertical axis (ie, an axis parallel to the third direction Z).

[0116] In order to rotate the turntable 230, a motor 290 may be provided in the mobile body 200. The motor 290 may be coupled to the base 220. The turntable 230 may rotate in coordination with the rotation of the motor 290. The rotational force of the motor 290 may be transmitted to the turntable 230 through a speed reducer. The motor 290 may rotate unidirectionally or reciprocate bidirectionally.

[0117] The turntable 230 is provided, and as a result, the shoes S can be rotated in the accommodation space 10, or the display effect of the shoes S can be enhanced.

[0118] The display device 1 may include an operation button 610 and a controller 600. The operation button 610 may be formed in the main body 100. As an example, the operation button 610 may be formed on the front surface of the upper main body 130. When the user manipulates the operation button 610, the turntable 230 may rotate or stop. The user manipulates the operation button 610 to adjust the rotation speed of the turntable 230. The user may input the rotation time of the turntable 230 into the controller 600 through the operation button 610.

[0119] The user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle. In a state in which the accommodation space 10 is opened, the user can place the shoe S on the upper surface of the turntable 230 by holding any one portion (top of the heel, lining, tongue, etc.) of the shoe S. Thereafter, the user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle.

[0120] As an example, the user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle so that the front-rear direction of the shoe S coincides with the first direction X. Alternatively, the user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle so that the front-rear direction of the shoe S forms a predetermined angle with the first direction X.

[0121] Therefore, even if the user places the shoe S on the upper surface of the turntable 230 while gripping any one portion of the shoe S, the shoe S can be placed (displaced) in a direction desired by the user.

[0122] A sensor (not shown) sensing the movement of the mobile body 200 may be provided in the body 100. When the receiving space 10 is closed, the controller 600 may rotate the turntable 230 by a signal of the sensor.

[0123] A load sensor (not shown) may be provided in the base 220. The load sensor may automatically measure the load of the shoe S placed on the turntable 230. The rotation speed of the turntable 230 according to the measurement value of the load sensor may be set in the controller 600. Alternatively, the user may input the rotation speed of the turntable 230 according to the measurement value of the load sensor into the controller 600 by operating the button 610.

[0124] A camera (not shown) may be provided in the display device 1. The camera may automatically photograph the shoes S placed on the turntable 230. The controller 600 may recognize the shape, size, and / or type of the shoes S through the photographed image of the camera.

[0125] The rotation speed of the turntable 230 according to the shape, size and / or type of the shoe S may be set in the controller 600 . Alternatively, the user may input the rotation speed of the turntable 230 according to the shape, size and / or type of the shoe S into the controller 600 by operating the button 610 .

[0126] The display device 1 may include an operation sensor. The operation sensor may sense the approach of a user. The turntable 230 may rotate or stop according to a sensing signal of the operation sensor.

[0127] Figure 3a It is shown Figure 1b A side view of the display device 1 in the usage state. Figure 3a A state in which the shoes S in the accommodation space 10 are irradiated is shown.

[0128] Figure 3b It is shown Figure 1b A front view of the display device 1 in the usage state. Figure 3b The air flow in the accommodation space 10 is shown.

[0129] The display device 1 according to the embodiment of the present invention may include a first lighting member 410. The first lighting member 410 may be provided in the upper body 130.

[0130] like Figure 3a As shown in FIG. 1 , the first lighting element 410 may illuminate the receiving space 10 . The first lighting element 410 may include a light source 411 and a lens 414 .

[0131] The light source 411 may intensively irradiate light onto the upper surface of the turntable 230 on which the shoes S are placed. The light of the light source 411 may intensively irradiate the shoes S placed on the upper surface of the turntable 230. When the lighting member 410 rotates, the image of the shoes S stored in the accommodation space 10 may be changed by the light of the light source 411.

[0132] The light of the light source 411 may illuminate the accommodation space 10 by passing through the lens 414. An ultraviolet ray blocking film may be attached to the lens 414, or an ultraviolet ray blocking agent may be coated on the lens 414, so as to block ultraviolet rays.

[0133] When the user manipulates the operation button 610, the light source 411 may be turned on or off. The user may input the operation time of the light source 411 into the controller 600 through the operation button 610. The user manipulates the operation button 610 to adjust the operation time of the light source 411.

[0134] Alternatively, the light source 411 may be turned on or off by operating a sensing signal of the sensor. The controller 600 may turn on-off the light source by operating a signal of the sensor.

[0135] Alternatively, the light source 411 may be turned on or off by a sensing signal of the sensor. When the receiving space 10 is closed, the controller 600 may turn on-off the light source by a signal of the sensor.

[0136] Alternatively, the operation time and operation mode of the light source according to the measurement value of the load sensor may be set in the controller 600. The user may input the operation time and operation mode of the light source 411 according to the measurement value of the load sensor into the controller 600 through the operation button 610.

[0137] Alternatively, the operation time and operation mode of the light source according to the shape, size and / or type of the shoe S may be set in the controller 600. The user may input the operation time and operation mode of the light source 411 according to the shape, size and / or type of the shoe S into the controller 600 through the operation button 610.

[0138] The light source 411 may be configured to change the color of the light. As an example, the light source 411 may be composed of a red, green, blue, and white (RGBW) LED. The controller 600 may control the current applied to the red (R) LED, the green (G) LED, the blue (B) LED, and the white (W) LED. When the controller 600 controls the current applied to the RGBW LED, the aesthetics and color sense of the shoes S stored in the accommodation space 10 may be changed differently. The user may input the mode of the current applied to the RGBW LED into the controller 600 by operating the button 610.

[0139] Figure 4a The first outer cabinet is shown with Figure 1a A three-dimensional diagram showing a state where the main body of the display device is separated. Figure 4b It is shown from Figure 1a A plan view showing a state where the main body of the display device is removed from the first outer cabinet. Figure 5 is a perspective cross-sectional view of the display device of FIG. 3 taken along line AA. Figure 5 Shoes not shown.

[0140] like Figures 4a to 5 As shown, the display device 1 may include a main body 100 , a mobile body 200 , a blowing part 330 , a first lighting element 410 , and a second lighting element 420 .

[0141] The main body 100 and the mobile body 200 may jointly form an accommodation space 10 for accommodating shoes S. The main body 100 and the mobile body 200 may be coupled to move relative to each other. The mobile body 200 may be coupled to the main body 100 to reciprocate in the front-rear direction.

[0142] The main body 100 may include an upper body 130. The upper body 130 may be positioned above the accommodation space 10. The upper body 130 may have an upper space 130a in which the airflow of the upper space is disconnected from the accommodation space. The upper space 130a may have a hexahedral shape, wherein the lengths in the first direction X and the second direction Y are greater than the length in the third direction Z.

[0143] The upper body 130 may include a first inner cabinet 135 and a first outer cabinet 136. The first inner cabinet 135 and the first outer cabinet 136 may form the accommodation space 10 together.

[0144] like Figure 4a As shown in FIG. 1 , the first inner cabinet 135 may have a rectangular box shape opened upward. The first inner cabinet 135 may have an air flow path 300 connected to the receiving space 10. The first inner cabinet 135 may include an upper bottom plate 135a.

[0145] The upper bottom plate 135a may separate the accommodation space 10 from the upper space 130a. The lower surface of the upper bottom plate 135a may form the top of the accommodation space 10. The upper surface of the upper bottom plate 135a may form the bottom of the upper space 130a. The upper bottom plate 135a may have a plate shape that is relatively wide in the horizontal direction.

[0146] The blowing part 330 is a component that circulates air in the accommodating space 10. The blowing part 330 and the air flow path 300 may be provided on an upper surface of the upper bottom plate 135a.

[0147] The blowing part 330 may include a fan 331 and a fan housing 332. The fan 331 may pressure-supply air through the rotational motion of an impeller. The fan housing 332 may constitute a part of the air flow path 300.

[0148] like Figure 2b As shown in FIG. 1 , the suction port 310 and the exhaust port 320 may be formed on the upper bottom plate 135 a .

[0149] The air in the accommodation space 10 may be sucked into the air flow path 300 through the suction port 310. The air in the air flow path 300 may be discharged to the accommodation space 10 through the discharge port 320. Therefore, the air forcibly blown by the blowing part 330 may circulate in the accommodation space 10 and the air flow path 300.

[0150] like Figure 5 As shown in FIG. 1 , the mobile body 200 may include a transparent window 210 , a base 220 , and a turntable 230 .

[0151] The body 100 may include a lower body 110. The lower body 110 may be positioned below the receiving space 10.

[0152] The base 220 may be coupled to the lower body 110 to be relatively movable in the front-rear direction, thereby opening / closing the accommodation space 10. The transparent window 210 may be coupled to the base 220. The transparent window 210 may form a front surface and two side surfaces (left and right surfaces) of the accommodation space 10.

[0153] The turntable 230 may be rotatably coupled to the base 220 about a vertical axis 231. The base 220 and the turntable 230 may jointly form a lower surface of the accommodation space 10. An upper surface of the turntable 230 may have a circular shape about the vertical axis 231.

[0154] The motor 290 may be provided in the base 220. The motor 290 may transfer a rotational motion to the turntable 230. The rotation axis 231 of the turntable 230 may be aligned with the vertical direction.

[0155] The axis of the motor 290 may be directly coupled to the rotation axis 231 of the turntable 230. The vertical axis 231 may represent the rotation axis 231 of the turntable 230. Figure 5 The alternating long and short dashed lines shown in may represent extension lines of the vertical axis 231 .

[0156] A power source (not shown) may be provided in the base 220. The power source may supply power to the motor 290. The controller 600 may control the power supplied to the motor 290 from the power source.

[0157] Figure 6 yes Figure 4b An exploded perspective view of the first lighting element 410 of the display device 1.

[0158] like Figure 5 and Figure 6 As shown in FIG. 2 , the first lighting member 410 may irradiate light onto an upper surface of the turntable 230 on which the shoe S is placed on an extension line of the vertical axis 231. The first lighting member 410 may be coupled to the upper bottom plate 135a.

[0159] The first lighting member 410 may include a light source 411 , an insertion housing 412 , a mounting housing 413 , and a lens 414 .

[0160] The light source 411 may irradiate light to the accommodation space 10. A power source (not shown) may be provided in the base 220. The power source may supply power to the light source 411. The controller 600 may control the power supplied to the light source 411 from the power source.

[0161] The light source 411 may be disposed on an extension line of the vertical axis 231. The accommodation space 10 may be parallel to the first direction X as a horizontal direction and form symmetry based on the reference plane RP as a vertical surface. The extension line of the vertical axis 231 may be positioned within the reference plane RP.

[0162] The light of the light source 411 may illuminate the shoes S placed on the bottom of the accommodation space 10. When the lighting member 410 rotates, the image of the shoes S stored in the accommodation space 10 may be changed by the lighting member of the light source 411.

[0163] When the user manipulates the operation button 610, the light source 411 may be turned on or off. The user may input the operation time of the light source 411 into the controller 600 through the operation button 610. The user manipulates the operation button 610 to adjust the operation time of the light source 411.

[0164] The light source 411 may be provided as an LED. Two terminals of the light source 411 may extend from the light source 411 in a horizontal direction. The two terminals may extend in directions opposite to each other.

[0165] The light source 411 may be formed of a white LED that emits white light. The light source 411 may show the shoes S accommodated in the accommodation space 10. Therefore, in a state in which the light around the display device 1 is off or weak, the visibility of the shoes S stored in the accommodation space 10 may be improved. Therefore, the display effect of the shoes S stored in the accommodation space 10 may be enhanced.

[0166] Alternatively, the light source 411 may be configured to change the color of the light. As an example, the light source 411 may be formed of a red, green, blue, and white (RGBW) LED. The controller 600 may control the current applied to the red (R) LED, the green (G) LED, the blue (B) LED, and the white (W) LED.

[0167] When the controller 600 controls the current applied to the RGBW LED, the aesthetics and color sense of the shoes S stored in the accommodation space 10 may be variously changed. The user may input a pattern of the current applied to the RGBW LED into the controller 600 through the operation button 610.

[0168] The main hole 135b and the circular protrusion 135c may be formed on the upper bottom plate 135a. The circular protrusion 135c may be formed to extend upward at the edge of the main hole 135b. The main hole 135b may extend in the up-down direction through the inner surface of the circular protrusion 135c.

[0169] like Figure 5 and Figure 6As shown in FIG. 4 , the insertion housing 412 may include an insertion sleeve 412 a , a first insertion bent portion 412 c , and a second insertion bent portion 412 d .

[0170] The insertion sleeve 412a may have a circular tube shape. The inner surface of the insertion sleeve 412a may form a circular hole 412b through which the light of the light source 411 passes. The insertion sleeve 412a may be inserted into the main hole 135b. The outer surface of the insertion sleeve 412a may be opposite to the inner surface of the circular protrusion 135c.

[0171] The first insertion bent portion 412c may be formed to extend outward on the outer surface of the insertion sleeve 412a. The first insertion bent portion 412c may be seated on the top of the circular protrusion portion 135c.

[0172] The second insertion curved portion 412d may be formed to extend downward from the first insertion curved portion 412c. The upper portion of the circular protrusion 135c may be inserted between the insertion sleeve 412a and the insertion curved portion. Therefore, the airflow of the upper space 130a and the accommodating space 10 passing through the circular protrusion 135c and the insertion housing 412 may be stopped.

[0173] The step portion 412e may be formed on the inner surface of the insertion sleeve 412a along the circumferential direction. The step portion 412e may form a second reflective surface 412f that reflects the light of the light source 411 that penetrates the lens 414. The second reflective surface 412f may be axially symmetrical about the vertical axis 231. The second reflective surface 412f may reflect the light of the light source 411 to the accommodation space 10.

[0174] like Figure 5 and Figure 6 As shown in FIG, the mounting housing 413 may include a mounting sleeve 413 a, a mounting bent portion 413 b, and a closing protrusion 413 c.

[0175] The light source 411 may be coupled to the mounting sleeve 413a. The light source 411 may be inserted into the interior of the mounting sleeve 413a. A plurality of grooves into which the two terminals of the light source 411 are downwardly inserted may be formed in the mounting sleeve 413a. The grooves of the mounting sleeve 413a may be formed in opposite directions around the vertical axis 231.

[0176] The diameter of the upper end portion of the mounting sleeve 413a can be smaller than the diameter of the light source 411. In the process of inserting the light source 411 into the inside of the mounting sleeve 413a, the mounting sleeve 413a may be bent outwardly. When the two terminals of the light source 411 are fully inserted into the grooves of the mounting sleeve 413a, the mounting sleeve 413a can be elastically restored. A protrusion can be formed on the inner surface of the upper end portion of the mounting sleeve 413a. Therefore, the mounting sleeve 413a can prevent the light source 411 from detaching.

[0177] The mounting sleeve 413a may be inserted into the interior of the insertion sleeve 412a. An outer surface of the mounting sleeve 413a may be opposite to an inner surface of the insertion sleeve 412a.

[0178] The lower portion of the mounting sleeve 413a may form a first reflective surface 413d that reflects the light of the light source 411 toward the lens 414. The first reflective surface 413d may form axisymmetry around the vertical axis 231. The first reflective surface 413d may reflect the light of the light source 411 to the accommodation space 10.

[0179] The mounting bent portion 413b may be formed to extend outward on an outer surface of the mounting sleeve 413a. The mounting bent portion 413b may be seated on top of the first insertion bent portion 412c.

[0180] A hook may be formed at any one of the mounting curved portion 413b and the second insertion curved portion 412d. In addition, a portion to which the hook is hooked may be formed at the other of the mounting curved portion 413b and the second insertion curved portion 412d. Therefore, when the mounting curved portion 413b is placed on top of the first insertion curved portion 412c, a coupling force may be formed between the insertion housing 412 and the mounting housing 413.

[0181] The closing protrusion 413c may extend downward on the lower end of the mounting sleeve 413a. The closing protrusion 413c may be formed around the vertical axis 231 in the circumferential direction.

[0182] The lens 414 may be inserted into the interior of the insertion sleeve 412a. The lens 414 may be mounted on the top of the step portion 412e. The top of the step portion 412e may form a contact surface with the lens 414 in the circumferential direction.

[0183] When the mounting sleeve 413a is inserted into the interior of the insertion sleeve 412a, the lens 414 can be in close contact with the bottom of the closed protrusion 413c. Therefore, the lens 414 can close the circular hole 412b. Therefore, the airflow of the upper space 130a and the accommodating space 10 passing through the circular hole 412b can be stopped.

[0184] The light of the light source 411 may illuminate the accommodation space 10 by passing through the lens 414. An ultraviolet ray blocking film may be attached to the lens 414, or an ultraviolet ray blocking agent may be coated on the lens 414 to block ultraviolet rays.

[0185] like Figure 5 As shown in FIG. 1 , the body 100 may include a middle body 120 . The middle body 120 may form a rear surface of the receiving space 10 .

[0186] The inner panel 500 may be coupled to the front surface of the middle body 120 in the accommodation space 10. Therefore, the turntable 230 may form the rear surface of the accommodation space 10 together with the middle body 120. The inner panel 500 may be detachably coupled to the middle body 120. As an example, the inner panel 500 may be coupled to the front surface of the middle body 120 by magnetic force.

[0187] Generally, the front surface of the middle body 120 may form a plane. The inner panel 500 may have a thin plate shape. The rear surface of the inner panel 500 may be in close contact with the front surface of the middle body 120. The front surface and / or rear surface of the inner panel 500 may form a similar shape and a similar area to the front surface of the middle body 120.

[0188] Therefore, even if the inner panel 500 is coupled or not coupled to the middle body 120, the hexahedral shape and size of the receiving space 10 can be substantially constantly maintained. Therefore, even if the inner panel 500 is coupled or not coupled to the middle body 120, the receiving space 10 can exhibit a predetermined aesthetic feeling based on the shape and size.

[0189] The front surface of the inner panel 500 may be made of the same or similar material as the front surface of the middle body 120 .

[0190] Therefore, even if the inner panel 500 is coupled or not coupled to the middle body 120, the light of the first lighting member 410 and the second lighting member 420 reflected on the rear surface of the accommodation space 10 can be transmitted in the same or similar manner to the field of vision of a person who sees the shoe S. Therefore, even if the inner panel 500 is coupled or not coupled to the middle body 120, the accommodation space 10 can exhibit a predetermined aesthetic feeling based on light.

[0191] The inner panel 500 may be configured to accommodate an image sheet 550. The image sheet 550 may refer to a sheet including an image to text. As an example, the image sheet 550 may be a sheet printed with a photo, a picture, or text.

[0192] The inner panel 500 may form an insertion space 500c for accommodating the image sheet 550. The inner panel 500 may include a transparent or semi-transparent material so as to expose the image sheet 550 to the accommodating space 10.

[0193] The image sheet 550 may be exposed to the field of vision of a person who sees the shoes S accommodated in the display apparatus 1. Therefore, the user of the display apparatus 1 may display photos and pictures on the rear surface of the accommodation space 10.

[0194] The insertion space 500c can be opened to the upper side. The image sheet 550 can be inserted into the insertion space 500c through the upper opening. The image sheet 550 inserted into the insertion space 500c can be taken out to the outside through the upper opening. Therefore, the user of the display device 1 can display various photos and pictures on the rear surface of the accommodation space 10.

[0195] Figure 7 yes Figure 4b An exploded perspective view of the second lighting element 420 of the display device 1.

[0196] like Figure 5 and Figure 7 As shown in FIG. 1 , the second lighting element 420 may illuminate the rear surface of the accommodation space 10. The second lighting element 420 may be parallel to the first direction X as the horizontal direction and form symmetry based on the reference plane RP as the vertical surface. The extension line of the vertical axis 231 may be positioned within the reference plane RP.

[0197] The second lighting member 420 may include a light source module 421 , a heat dissipation cover 424 , and a transmission cover 425 .

[0198] like Figure 4b and Figure 7 As shown in , the light source module 421 may be formed to be long in the second direction Y. The light source module 421 may be formed of an LED module. The light source module 421 may include a module substrate 422 and a plurality of white LEDs.

[0199] A power source (not shown) may be provided in the base 220. The power source may supply power to the light source module 421. The controller 600 may control the power supplied to the light source module 421 from the power source.

[0200] The module substrate 422 may be formed to be long in the second direction Y. A plurality of LEDs may be placed on the bottom of the module substrate 422 with a predetermined gap in the second direction Y. Therefore, the light irradiated from the light source module 421 onto the rear surface of the accommodation space 10 may form a substantially constant illuminance in the second direction Y.

[0201] Therefore, the visibility of the rear surface of the storage space 10 is enhanced, and as a result, the display effect of the image sheet 550 contained in the inner panel 500 can be enhanced. In particular, in a state where the light around the display device 1 is turned off or weak, the display effect of the image sheet 550 contained in the inner panel 500 can be enhanced.

[0202] Alternatively, the light source module 421 may be configured to change the color of light. As an example, the light source module 421 may be composed of a module substrate 422 and a plurality of red, green, blue, and white (RGBW) LEDs. The controller 600 may control the current applied to the red (R) LED, the green (G) LED, the blue (B) LED, and the white (W) LED.

[0203] When the controller 600 controls the current applied to the RGBW LED, the aesthetics and color sense of the rear surface of the accommodating space 10 may be variously changed. The user may input a mode of the current applied to the RGBW LED 423 into the controller 600 through the operation button 610.

[0204] Meanwhile, the wavelength of the light of the second lighting member 420 may vary according to the temperature and / or humidity of the accommodation space 10. Here, the wavelength change range may be the wavelength range of visible light. That is, the wavelength change range may be 400 nm to 700 nm.

[0205] like Figure 5 As shown in FIG. 1 , a measuring sensor 138 measuring temperature and / or humidity may be installed at one side of the accommodation space 10. The measuring sensor 138 may be installed in the upper body 130, the middle body 120, or the base 220. As an example, the measuring sensor 138 may be installed on the upper base plate 135a. The controller 600 may receive the measured value of the measuring sensor 138.

[0206] The controller 600 may control the current applied to the RGBW LED 423 according to the measurement value of the measurement sensor 138. The wavelength of the light emitted by the second lighting member 420 may vary according to the measurement value of the measurement sensor 138. Therefore, the color stimulation of the light reflected on the rear surface of the accommodating space 10 may vary according to the measurement value of the measurement sensor 138.

[0207] Color stimulation is a term that refers to the stimulation of the color sense given to the eyes by the reflected light of a colored object. When the human eye is stimulated by light, there are three color senses of sensing red, green and blue, and colors can be displayed by the stimulation amount (triple stimulus value) for the three color senses.

[0208] The amount of current applied to the RGBW LED 423 may be set in the controller 600 according to the measurement value of the measurement sensor 138. Alternatively, the user may input the amount of current applied to the RGBW LED 423 according to the measurement value of the measurement sensor 138 into the controller 600 by operating the button 610.

[0209] An appropriate temperature range may be input into the controller 600. The appropriate temperature range may refer to a temperature range suitable for storing the shoes S. The controller 600 may change the amount of current applied to the RGBW LED 423 within the appropriate temperature range according to the measurement value of the measurement sensor 138.

[0210] As an example, when the measurement value of the measurement sensor 138 is within an appropriate temperature range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 emits green light or blue light.

[0211] As an example, when the measurement value of the measurement sensor 138 is outside the appropriate temperature range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 emits red light.

[0212] Alternatively, when the measurement value of the measurement sensor 138 is out of an appropriate temperature range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 continuously flashes light of a specific color.

[0213] An appropriate humidity range may be input into the controller 600. The appropriate humidity range may refer to a humidity range suitable for storing the shoes S. The controller 600 may change the amount of current applied to the RGBW LED 423 within the appropriate humidity range according to the measurement value of the measurement sensor 138.

[0214] As an example, when the measurement value of the measurement sensor 138 is within an appropriate humidity range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 emits green light or blue light.

[0215] As an example, when the measurement value of the measurement sensor 138 is outside the appropriate humidity range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 emits red light.

[0216] Alternatively, when the measurement value of the measurement sensor 138 is out of an appropriate humidity range, the controller 600 may apply current to the RGBW LED 423 so that the second lighting member 420 continuously flashes light of a specific color.

[0217] like Figure 5 and Figure 7 As shown in FIG. 4 , the heat dissipation cover 424 and the transmission cover 425 may be formed to be longer in the second direction Y. As shown in FIG.

[0218] The light source module 421 may be connected to the heat dissipation cover 424. The heat dissipation cover 424 may form an opening at a lower side thereof. The transmissive cover 425 may be coupled to the heat dissipation cover 424 so as to seal the opening of the heat dissipation cover 424.

[0219] The hook 424a may be formed in any one of the heat dissipation cover 424 and the transmissive cover 425. The hook hole 425b to which the hook 424a is hooked may be formed in any one of the heat dissipation cover 424 and the transmissive cover 425. When the transmissive cover 425 seals the opening of the heat dissipation cover 424, the hook 424a may be hooked to the hook hole 425b. Therefore, a coupling force may be formed between the heat dissipation cover 424 and the transmissive cover 425.

[0220] Therefore, the heat dissipation cover 424 and the transmissive cover 425 may form together a space (hereinafter referred to as a “light source space”) for accommodating the light source module 421. The light source space may be formed to be long in the second direction Y.

[0221] The top of the module substrate 422 may be coupled to a heat dissipation cover 424 above the light source space. Heat energy of the light source module 421 may be transferred to the heat dissipation cover 424. The heat dissipation cover 424 may discharge heat of the light source module 421 to the upper space 130a. The heat dissipation cover 424 may be made of a metal material having high thermal conductivity.

[0222] The LED 423 may be disposed on the bottom of the module substrate 422. The transmissive cover 425 may include a transmissive portion 425a that transmits light of the light source module 421. The transmissive portion 425a may be formed to be long in the second direction Y.

[0223] Therefore, the light of the light source module 421 penetrating the transmission part 425a may form a substantially constant illumination in the second direction Y. The transmission cover 425 may be made of a transparent glass or resin material. The front surface of the transmission cover 425 except the transmission part 425a may be coated with an opaque material.

[0224] A hole (hereinafter referred to as a "rear surface hole") into which the transmission part 425a is inserted may be formed on the upper bottom plate 135a. The rear surface hole may be formed to be longer in the second direction Y. The transmission part 425a may be inserted into the rear surface hole. The outer surface of the transmission part 425a may be in close contact with the inner surface of the rear surface hole. Therefore, the airflow of the upper space 130a and the accommodating space 10 through the transmission cover 425 and the inner surface of the rear surface hole may be stopped.

[0225] Figure 8a yes Figure 3b A cross-sectional view of the display device 1 taken along line CC. Figure 8b yes Figure 3a A cross-sectional view of the display device 1 taken along line AA. Figure 8bThe alternating long and short dashed lines shown in may represent extension lines of the vertical axis 231 .

[0226] The accommodation space 10 may be parallel to the first direction X as a horizontal direction, and form symmetry based on the reference plane RP as a vertical surface. An extension line of the vertical axis 231 may be positioned within the reference plane RP.

[0227] like Figure 8a and Figure 8b As shown in , the light source 411 may be disposed on the extension line of the vertical axis 231. The first lighting member 410 may irradiate light onto the top of the turntable 230, on which the shoe S is placed on the extension line of the vertical axis 231.

[0228] Figure 8a and Figure 8b The alternating long and short dashed arrows shown in may represent extension lines of the first reflective surface 413d. Figure 8a and Figure 8b The alternating long and short dashed arrows shown in 412a may represent extension lines of the second reflective surface 412f.

[0229] As described above, in a state in which the accommodation space 10 is opened, the user may place the shoe S on top of the turntable 230 by holding any portion of the shoe S (top of the heel, lining, tongue, etc.).

[0230] Thereafter, the user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle so that the front-rear direction of the shoe S coincides with the first direction X.

[0231] Alternatively, the user manipulates the operation button 610 to rotate the turntable 230 at a predetermined angle so that the front-rear direction of the shoe S forms a predetermined angle with the first direction X. Alternatively, the user manipulates the operation button 610 to rotate the turntable 230 continuously.

[0232] The beam angle of the first lighting element 410 may form axisymmetry around the vertical axis 231. Therefore, the light emitted by the first lighting element 410 may form the same illumination around the vertical axis 231 in the circumferential direction.

[0233] Therefore, regardless of the direction in which the front-back direction of the shoe S faces, the light reflected on the surface of the shoe S can maintain the same color stimulation. Therefore, regardless of the direction in which the front-back direction of the shoe S faces, the aesthetics and color sense of the shoe S stored in the accommodation space 10 can be maintained the same.

[0234] As described above, the transparent window 210 may form the front surface and both side surfaces (left and right surfaces) of the receiving space 10 . The transparent window 210 may include a first window 211 , a second window 212 , and a third window 213 .

[0235] The first window 211 may form a front surface of the accommodation space 10. The second window 212 may form a left surface of the accommodation space 10. The third window 213 may form a right surface of the accommodation space 10.

[0236] Therefore, the user can observe the shoes S accommodated in the accommodation space 10 at the front, left and right sides. In addition, the user can observe the shoes S accommodated in the accommodation space 10 between the front and left sides of the accommodation space 10 and between the front and right sides of the accommodation space 10.

[0237] The beam angle of the first lighting element 410 forms axisymmetry around the vertical axis 231, and as a result, the light reflected on the surface of the shoes S can maintain the same color stimulation regardless of the position of the user based on the accommodation space 10. Therefore, the aesthetics and color sense of the shoes S stored in the accommodation space 10 can be maintained the same.

[0238] Hereinafter, for ease of understanding of the present invention, the space between the extension line of the vertical axis 231 and the extension line of the first reflective surface 413d will be referred to as the "first space". In addition, the space between the extension line of the first reflective surface 413d and the extension line of the second reflective surface 412f will be referred to as the "second space".

[0239] like Figure 5 As shown in FIG, the first reflective surface 413d may be disposed around the extension line of the vertical axis 231 beside the light source 411. The second reflective surface 412f may be disposed below the first reflective surface 413d. The first reflective surface 413d and the second reflective surface 412f may form a surface that reflects the light of the light source 411 toward the accommodation space 10.

[0240] The second reflective surface 412f may be spaced farther from the extension line of the vertical axis 231 than the first reflective surface 413d. In addition, the extension line of the second reflective surface 412f may be spaced farther from the vertical axis 231 than the extension line of the first reflective surface 413d. Therefore, the light reflected by the second reflective surface 412f may form a lower illumination than the light reflected by the first reflective surface 413d.

[0241] like Figure 8a and Figure 8b As shown in , the light of the first lighting element 410 can form a higher illumination in the first space than in the second space. The extension line of the first reflective surface 413d can face the edge of the turntable 230. Therefore, the first lighting element 410 can intensively illuminate the shoes S placed on the top of the turntable 230. Therefore, the display effect of the shoes S placed on the top of the turntable 230 can be enhanced.

[0242] When the shoe S is placed close to the edge of the turntable 230 based on the vertical axis 231, a portion of the shoe can be positioned in the second space. In addition, when the shoe S is formed to be long in the vertical direction like a boot, a portion of the shoe S can be positioned in the second space.

[0243] The light of the first lighting element 410 forms a lower illumination in the second space than in the first space, and the portion of the shoe S positioned in the second space can be illuminated. Therefore, even if a portion of the shoe S is positioned outside the first space, the first lighting element 410 can fully illuminate the shoe S placed on the top of the turntable 230.

[0244] Therefore, even if a portion of the shoe S is positioned in the second space, the light reflected on the surface of the shoe S can generally maintain the same color stimulation. Therefore, the aesthetics and color sense of the shoe S stored in the accommodation space 10 can generally maintain the same.

[0245] Figure 8b The dotted line shown in FIG. 4 may represent a process in which light from the second lighting element 420 penetrates the transmissive surface. Figure 8b The dotted arrow shown in the enlarged view may represent the normal direction of the transmission surface.

[0246] According to Snell's law, when light is incident on a boundary surface of two media having different densities, the reflectivity of the light increases as the incident angle increases. Therefore, the transmissive portion 425a can transmit light having a smaller incident angle of the light source module 421 toward the receiving space 10.

[0247] In addition, the transmissive portion 425a may reflect light having a larger incident angle of the light source module 421. Therefore, the light of the light source module 421 penetrating the transmissive portion 425a may form a higher illuminance around the normal direction of the bottom of the transmissive portion 425a.

[0248] like Figure 8b As shown in FIG. 1 , the normal direction of the bottom of the transmissive portion 425a contacting the receiving space 10 may face the front surface of the inner panel 500. The top of the transmissive portion 425a may form a surface parallel to the bottom. Therefore, the second lighting element 420 may intensively illuminate the rear surface of the receiving space 10.

[0249] Therefore, the visibility of the rear surface of the storage space 10 is enhanced, and as a result, the display effect of the image sheet 550 contained in the inner panel 500 can be enhanced. In particular, in a state where the light around the display device 1 is turned off or weak, the display effect of the image sheet 550 contained in the inner panel 500 can be enhanced.

[0250] Fig. 9is a diagram showing an example of a state in which a shoe image is input and the second lighting member 420 is recommended in the presentation apparatus 1 according to an embodiment of the present disclosure. Fig.10 and Fig.11 is a diagram illustrating an example of a process of recommending the second lighting member 420 in the presentation apparatus 1 according to an embodiment of the present disclosure. Fig.12 is a diagram showing an example of processing according to an area on the CIE LAB color coordinates when the second lighting 420 is recommended in the presentation apparatus 1 according to the embodiment of the present disclosure. Fig.13 is a diagram showing an example of the type of the second lighting member 420 recommended to the user in the presentation apparatus 1 according to the embodiment of the present disclosure.

[0251] Will refer to Figures 9 to 13 An algorithm for recommending the most suitable lighting element to the user based on the shoes accommodated in the accommodation space 10 in the display device 1 according to an embodiment of the present disclosure is described. In this case, reference will also be made to the above Figures 1a to 8b Give a description.

[0252] The display apparatus 1 according to an embodiment of the present disclosure may include a body 100 , a moving body 200 , a blowing part 330 , a first lighting part 410 , a second lighting part 420 , an input part 710 , and a controller 600 .

[0253] The body 100 is a portion forming a part of the receiving space 10 , and may form a reference position for a moving body 200 that moves to open and close the receiving space 10 .

[0254] The mobile body 200 is a part that forms the receiving space 10 together with the body 100, and includes a transparent window 210. That is, the mobile body 200 is a part that forms the rest of the receiving space 10, and the mobile body 200 can move relative to the body 100 to open and close the receiving space 10.

[0255] In particular, the mobile body 200 can be configured to reciprocate between a first position and a second position in the forward and backward directions relative to the main body 100. In this case, the state in which the mobile body 200 is in the first position can be defined as a closed state, and the state in which the mobile body 200 is in the second position can be defined as an open state.

[0256] The receiving space 10 may be sealed and isolated from the outside air in the closed state of the display device 1. Therefore, when the receiving space 10 is closed after the shoes are received in the receiving space 10, the shoes may be prevented from being exposed to dust and moisture in the outside air.

[0257] The blowing part 330 is configured to circulate air in the accommodation space 10, and can control the air condition (especially humidity) of the accommodation space 10 so that the shoes accommodated in the accommodation space 10 are placed in a suitable environment.

[0258] In this case, the suction port 310 and the exhaust port 320 may be respectively formed in a portion of the accommodation space 10. In addition, the air of the accommodation space 10 may be sucked into the air flow path 300 through the suction port 310 by the blowing portion 330, and the air of the air flow path 300 may be exhausted back to the accommodation space 10 through the exhaust port 320 by the blowing portion 330. Therefore, the air forcibly blown by the blowing portion 330 may circulate through the accommodation space 10 and the air flow path 300.

[0259] As described above, since the display device 1 according to the present embodiment accommodates shoes in the accommodation space 10 formed by the main body 100 and the mobile body 200, switches to a closed state, and displays the shoes while controlling the state of the accommodation space 10 by circulating air in the accommodation space 10 via the blowing part 330, it is possible to effectively achieve a shoe display effect and a shoe management effect at the same time.

[0260] The first lighting member 410 is to illuminate a portion of the shoes placed on the bottom of the accommodation space 10 , and may centrally illuminate the shoes S placed on the upper surface of the turntable 230 , thereby improving the display effect of the shoes S.

[0261] The second lighting element 420 is a part that illuminates the rear surface of the storage space 10, and can improve the visibility of the rear surface of the storage space 10 and provide a visual effect for the shoes as a background. In addition, the second lighting element 420 is configured to change the color of the light, thereby changing the aesthetics and color of the rear surface of the storage space 10.

[0262] As described above, in the display device 1 according to this embodiment, the first lighting element 410 can focus on illuminating the area where shoes are placed, and the second lighting element 420 can illuminate the rear surface of the accommodating space 10, thereby maximizing the display effect of the shoes and improving the internal effect of the space for accommodating shoes.

[0263] Meanwhile, when the visual effect of the shoe and the receiving space 10 is enhanced by the lighting as described above, it may be desirable to adjust the lighting to best match the received shoe.

[0264] In particular, since the color of the light from the second lighting member 420 can be varied to change the aesthetics and color of the rear surface of the receiving space 10, it may be desirable to adjust the second lighting member 420 so that it reflects the characteristics of the received shoes.

[0265] In this case, it is not easy for the user to determine which lighting element best matches the accommodated shoes, so the display device 1 according to this embodiment can well recommend the type of second lighting elements 420 that match the accommodated shoes to guide the user to select one of them.

[0266] In this regard, the input part 710 is a portion to which an image of the shoes accommodated in the accommodation space 10 is input, and the image of the shoes may be input as basic data for analyzing the type of the second lighting member 420 well matched with the accommodated shoes.

[0267] In addition, the controller 600 can recommend the type of the second lighting member 420 to the user based on the shoe image input to the input part 710. That is, the controller 600 can analyze the type of the second lighting member 420 that matches the received shoe well based on the input image of the shoe as basic data, and then recommend it to the user.

[0268] As described above, in the display device 1 according to the present embodiment, the controller 600 can recommend to the user a second lighting element 420 that well matches the image of the shoes input into the input unit 710, thereby enabling the user to more easily select the type of the second lighting element 420 and improve the aesthetics by the second lighting element 420 reflecting the characteristics of each shoe.

[0269] The display device 1 according to an embodiment of the present disclosure may further include a portable device 700 equipped with an input portion 710 and capable of remote communication with the controller 600. In this case, an image of the shoe may be captured by the portable device 700 and input to the input portion 710, and the type of the second lighting member 420 recommended to the user by the controller 600 may be displayed by the portable device 700.

[0270] That is to say, Fig. 9 As shown, when a user carries a portable device 700 configured separately from the display apparatus 1 , an image of the shoes accommodated in the display apparatus 1 may be captured by an input unit 710 provided in the portable device 700 .

[0271] In addition, the controller 600 may analyze the type of the second lighting member 420 that is well matched with the received shoes based on the image captured by the portable device 700, and Fig. 9 As shown, the type of the second lighting element 420 to be recommended is displayed by the portable device 700 .

[0272] As described above, in the display apparatus 1 according to the present embodiment, since the image of the shoes is input through the portable device 700 and since the type of the second lighting component 420 to be recommended is displayed through the portable device 700, the image of the shoes can be input and the type of the second lighting component 420 to be recommended can be identified more conveniently.

[0273] In the presentation apparatus 1 according to an embodiment of the present disclosure, the portable device 700 may display a reference line 720 corresponding to the outer lines of the body 100 and the mobile body 200 when capturing an image of the shoe.

[0274] That is to say, Fig. 9 and Fig.10 As shown, when the user captures an image of the shoe using the portable device 700 , a reference line 720 corresponding to the external shape of the display apparatus 1 may be displayed on the screen of the portable device 700 .

[0275] Therefore, the user can align the actual shape of the actual display device 1 with the reference line 720 of the portable device 700 and then capture the actual shape of the actual display device 1. Thus, when capturing an image using the portable device 700, the image of the shoe can always be captured in a specific composition and a specific size.

[0276] As described above, in the display apparatus 1 according to the present embodiment, since the reference line 720 is displayed when capturing an image of the shoe using the portable device 700, the image can always be captured with a similar composition even if the photographer is different, thereby enabling more accurate input of the image for recommending the second lighting element 420.

[0277] In the display apparatus 1 according to the embodiment of the present disclosure, when an image of the shoe is captured using the portable device 700 , the controller 600 may control the first lighting member 410 to illuminate the shoe.

[0278] When capturing an image of a shoe using the portable device 700, the image of the shoe to be captured may vary according to the capturing time or surrounding environment. Therefore, it is important to recommend the second lighting element 420 according to the influence of the capturing time or surrounding environment rather than reflecting the unique characteristics of the shoe.

[0279] Therefore, when capturing a shoe image through the portable device 700, it may be desirable to have the first lighting member 410 illuminate the shoe so that the accommodation space 10 remains in a relatively constant state even if the capturing time or the surrounding environment changes.

[0280] As described above, in the display apparatus 1 according to the present embodiment, even if the capture time of the shoe image and the surrounding environment vary, the image can be more accurately input for recommending the second lighting member 420 by always capturing the image in a similar state.

[0281] In the display apparatus 1 according to an embodiment of the present disclosure, an image of shoes input through the input part 710 may be captured by the portable device 700 , and then the dummy area Ad may be removed from the image ( S100 ).

[0282] As described above, even if an image of a shoe is captured with the reference line 720 displayed, a dummy area Ad not related to the shoe may be generated according to the size of the accommodated shoe or the like.

[0283] Since the dummy area Ad is not associated with basic data for analyzing the type of the second lighting member 420 that is well matched to the accommodated shoe, it may be desirable to analyze the type of the second lighting member 420 after excluding the dummy area Ad.

[0284] To this end, the accommodation space 10 may be divided into a plurality of horizontal sections and a plurality of vertical sections, and sections other than a specific section may be regarded as a dummy area Ad. Alternatively, the dummy area Ad may be removed using computer vision techniques including YOLOv5 or techniques for segmenting regions of objects in captured images.

[0285] Alternatively, various techniques and methods may be used to remove the dummy area Ad as needed, such as having the user directly cut out the dummy area Ad from the shoe image captured on the portable device 700 .

[0286] As described above, in the display apparatus 1 according to the present embodiment, since the dummy area Ad is removed when capturing an image of the shoe using the portable device 700, portions of the image that do not need to be reflected when recommending the second lighting element 420 can be excluded, thereby enabling the recommendation of the second lighting element 420 to be performed more effectively.

[0287] Meanwhile, the image of the shoe from which the dummy area Ad is removed may be subjected to white balancing so that the characteristics of the shoe may be more accurately reflected as basic data.

[0288] In the display device 1 according to an embodiment of the present disclosure, the second lighting element 420 can be configured to be changed to any one of a plurality of preset lighting elements. In this case, the controller 600 can recommend to the user at least one of a similar color temperature lighting element Lk, a similar monochromatic lighting element Lc, and a similar spectrum lighting element Ls for the image of the shoe among the preset lighting elements (S200, S500, and S700).

[0289] The preset lighting element indicates that the lighting element is preset to a specific state, wherein the second lighting element 420 may be changed during the design and / or manufacture of the display device 1 .

[0290] Among them, the similar color temperature lighting element Lk may be a preset lighting element having a color temperature most similar to the image of the shoe. In addition, the similar monochromatic lighting element Lc may be a preset lighting element having a color most similar to the image of the shoe. In addition, the similar spectrum lighting element Ls may be a lighting element in a spectrum state having a color most similar to the image of the shoe.

[0291] As described above, since the display device 1 according to this embodiment recommends at least one of the similar color temperature lighting elements Lk, similar monochromatic lighting elements Lc and similar spectrum lighting elements Ls among the pre-set preset lighting elements to the user, recommendations reflecting the accommodated shoes can be made in various ways, thereby improving the user's utilization of the second lighting element 420.

[0292] In the display apparatus 1 according to the embodiment of the present disclosure, the similar color temperature lighting element Lk may be a preset lighting element recommended according to the average color temperature of pixels whose brightness (value) in the image of the shoe is within the upper set range.

[0293] As one method of selecting the type of second lighting element 420 that is a good match for the accommodated shoe, the brightest pixel can be individually extracted from the captured image of the shoe, and the brightest pixel can be analyzed to analyze which color temperature of the preset lighting elements among the preset lighting elements that imitate the standard light source matches the brightest pixel.

[0294] In this case, the values ​​of the pixels of the shoe image can be converted into HSV units, so that the pixels whose brightness is within the upper set range (e.g., upper 10%) can be extracted separately. Then, the average color temperature of the extracted pixels can be calculated to recommend the closest preset lighting element as the similar color temperature lighting element Lk.

[0295] To this end, color conversion technology may be used, and various functions included in Colour Science for Python may be used for calculation, but the present disclosure is not necessarily limited thereto, and various technologies and methods may be employed as needed.

[0296] As described above, in the display device 1 according to the present embodiment, since similar color temperature lighting elements Lk that match well with pixels with relatively high brightness in the shoe image are recommended, the second lighting element 420 having the most similar color temperature to the shoe image can be recommended.

[0297] In the display apparatus 1 according to the embodiment of the present disclosure, the similar monochromatic lighting element Lc may be a preset lighting element recommended according to a color having the highest ratio in the color palette Cp reflecting pixels having relatively high chromaticity in the image of the shoe.

[0298] In this case, the color palette Cp indicating the primary colors constituting the image of the shoe is derived as a result of multiple clustering, such as Fig.10 shown.

[0299] As another method of selecting the type of second lighting element 420 that matches the accommodated shoe well, colors with high chroma may be emphasized and analyzed in the captured shoe image to analyze which color of preset lighting elements matches the shoe well.

[0300] In this regard, it is well known that when observing an object, people tend to place more weight on a color with higher chroma than on an actual color, depending on cognitive memory color. Therefore, a method of analyzing a color with higher chroma to be emphasized among the colors of the captured shoe image and then recommending the same color as the similar monochromatic lighting element Lc may be important to consider.

[0301] As described above, in the display device 1 according to the present embodiment, since a similar monochromatic lighting element Lc that matches well with pixels with higher chroma in the shoe image is recommended, the second lighting element 420 can be recommended to reflect the tendency to place more weight on colors with higher chroma rather than on actual colors when identifying objects.

[0302] In the display device 1 according to the embodiment of the present disclosure, the value (a*) in the image of the shoe can be obtained by moving the value (a*) in the image of the shoe to the three-dimensional coordinates defined by L*, a* and b*. 2 +(b*) 2 ) 1 / 2 The number of pixels greater than or equal to the first set value is enlarged (S300), and then a plurality of clusters are derived from the value using a clustering algorithm (S400) to obtain a color palette Cp, the L*, a*, and b* being a color space for color recognition.

[0303] In this case, the three-dimensional coordinates defined by L*, a*, and b* as a color space for color recognition may be LAB color coordinates of the International Commission on Illumination (CIE). In addition, L* represents brightness information and indicates 0 (black) to 100 (white). a* represents negative a (green) to positive a (red). b* represents negative b (blue) to positive b (yellow).

[0304] As described above, in order to emphasize a color with high chroma among the colors in the captured shoe image, the value of the pixel of the shoe image may be converted into a Lab unit, and the value (a*) may be amplified (for example, increased by 30 times) 2 +(b*) 2 ) 1 / 2 The number of pixels greater than or equal to a first set value (eg, 35).

[0305] To this end, although the color conversion function included in Python color science may be used, the present disclosure is not necessarily limited thereto, and various techniques and methods may be utilized as needed.

[0306] Furthermore, in order to analyze what colors constitute the captured shoe image, a clustering algorithm may be used to derive a color palette Cp comprising a plurality (eg, 12) of clusters from the color values ​​of the corresponding pixels calculated above.

[0307] To this end, although K-means clustering, fuzzy C-means, etc. can be used, the present disclosure is not necessarily limited thereto, and various techniques and methods can be used as needed.

[0308] As described above, since the display apparatus 1 according to the present embodiment uses the color palette Cp obtained by enlarging pixels with higher chromaticity in the shoe image and classifying them into clusters, the second lighting member 420 can be recommended by using analysis that emphasizes colors with higher chromaticity.

[0309] In the presentation apparatus 1 according to an embodiment of the present disclosure, the controller 600 may recommend similar monochromatic lighting elements Lc in order of the shortest Euclidean distance from the color having the highest ratio in the color palette Cp derived as the plurality of clusters.

[0310] In this case, when calculating the distance between two points, the Euclidean distance is obtained by expressing the two points as coordinates, adding the square of the difference of the corresponding components, and then calculating its square root.

[0311] Therefore, the color with the highest ratio can be set as the main color in the palette Cp derived as described above, and the Euclidean distance between the Lab value of the main color and the Lab value of the preset lighting element can be calculated, so that similar monochrome lighting elements Lc can be recommended in ascending order starting from the shortest distance.

[0312] As described above, in the display device 1 according to the present embodiment, since similar monochrome lighting elements Lc are recommended in an order that matches well with the color with the highest proportion in the color palette Cp derived as multiple clusters, the recommended order of the second lighting elements 420 can be determined in an order similar to the color of the shoe.

[0313] In the display device 1 according to an embodiment of the present disclosure, the similar spectrum lighting element Ls may be a preset lighting element in a spectrum state recommended in order of the shortest Euclidean distance from the color having the highest ratio in the color palette Cp.

[0314] In this case, the spectrum state indicates a state in which colors are distributed and arranged in the order of wavelengths, such as Fig.10 shown.

[0315] Another method of selecting the type of second lighting element 420 that matches the accommodated shoe well is to analyze which color of preset lighting elements among the preset lighting elements matches well and recommend this color in a spectral state rather than a monochromatic state.

[0316] That is, a method of recommending the most similar color as the similar spectrum lighting element Ls in the spectrum state based on the primary colors constituting the image of the shoe may also be importantly considered.

[0317] As described above, in the display device 1 according to the present embodiment, since similar spectrum lighting components Ls in the spectral state are recommended in an order that matches well with the color with the highest proportion in the color palette Cp exported as multiple clusters, the recommended order of the second lighting components 420 in the spectral state can be determined in an order similar to the color of the shoes.

[0318] In the display apparatus 1 according to an embodiment of the present disclosure, if the maximum value of the Euclidean distances between three colors with relatively high distribution in the color palette Cp is greater than or equal to the second set value, the colors included in the shoe image may be considered diverse ( S600 ).

[0319] When recommending a second lighting element 420 that reflects the characteristics of the accommodated shoe, although colors in a monochrome or spectral state can be recommended based on primary colors as described above, this can also be an important consideration if the image of the shoe is configured in a variety of colors rather than colors in a specific family.

[0320] This is because in the case where the accommodated shoes have various colors, recommending a color in a specific family close to a primary color may result in not reflecting the characteristics of the shoe.

[0321] Therefore, the Euclidean distance between the corresponding colors can be calculated by the values ​​a* and b* of the three colors with the highest distribution in the palette Cp extracted as described above. In addition, if the maximum value of the calculated distance is greater than the second set value (e.g., 35), the shoe can be regarded as having various colors rather than colors in a specific family.

[0322] That is, if the maximum value of the calculated distances is greater than a second set value (e.g., 35), it may indicate that at least two of the three colors with the highest distribution in the extracted palette Cp are far away from each other in color coordinates, and therefore it is more appropriate to view the image of the shoe as having a variety of colors rather than colors in a specific family.

[0323] As described above, since the display device 1 according to the present embodiment determines whether the shoe image has multiple colors by deriving the Euclidean distance between three colors with relatively high distribution in the palette Cp for multiple clusters, the second lighting element 420 can be recommended by utilizing analysis reflecting the situation where the shoe has various colors.

[0324] In the display device 1 according to an embodiment of the present disclosure, if the colors included in the image of the shoes are considered to be diverse or if the absolute values ​​of a* and b* of the color with the highest proportion in the color palette Cp are both less than the third set value, the controller 600 can preferentially recommend a rainbow-type similar spectrum lighting component Ls.

[0325] In this case, the rainbow type indicates a type in which the similar spectrum lighting parts Ls are configured as a plurality of colors between red and purple rather than colors in a specific family, which are dispersed and arranged by dispersion of visible light.

[0326] As described above, if the accommodated shoes are configured in various colors, it may be desirable to recommend similar spectrum lighting members Ls of a rainbow type rather than recommending colors in a specific family close to primary colors.

[0327] In addition, if Fig.12 As shown, if the absolute values ​​of a* and b* of the color with the highest proportion in the palette Cp are both less than the third set value (for example, 5), the attributes of the primary color do not belong to a specific color family and are not different, so in this case as well, it is also expected to recommend a rainbow-type similar spectrum lighting piece Ls instead of recommending a color in a specific family.

[0328] As described above, in the display device 1 according to the present embodiment, if the shoe image has various colors or if the attributes of the color with the highest proportion in the color palette Cp exported as multiple clusters are not different, the rainbow-type similar spectrum lighting element Ls is preferentially recommended, and thus the second lighting element 420 can be recommended to reflect the situation where there is no bias toward a specific color.

[0329] In the display device 1 according to the embodiment of the present disclosure, if the color ((a*)) having the highest proportion in the color palette Cp is 2 +(b*) 2 ) 1 / 2 If the value of is less than or equal to the fourth setting value, the shoe image may be regarded as achromatic (S800).

[0330] When recommending a second lighting 420 that reflects the characteristics of the received shoe, if the image of the shoe is neutral, it may also be an important factor to consider.

[0331] This is because, if the received shoe is non-colored, it may not pair well with the second lighting element 420 that reflects a color.

[0332] Therefore, the primary colors can be converted to Lab values ​​to calculate the corresponding color ((a*) 2 +(b*) 2 ) 1 / 2 In addition, as described above, since pixels having calculated values ​​higher than the first set value (e.g., 35) are relatively dark colors, they can be amplified more than other pixels. Therefore, when the palette Cp is extracted, such colors may be output as primary colors. However, if the primary color ((a*) 2 +(b*) 2 ) 1 / 2If the value of is lower than a fourth setting value (eg, 35), the corresponding image of the shoe may be considered as non-color.

[0333] As described above, since the display device 1 according to the present embodiment determines whether the image of the shoe is achromatic by deriving the attribute of the color with the highest proportion in the palette Cp of multiple clusters, the second lighting element 420 can be recommended by utilizing analysis reflecting the situation that the shoe is achromatic.

[0334] In the display apparatus 1 according to an embodiment of the present disclosure, if the image of the shoe is considered to be achromatic, the controller 600 may recommend the similar color temperature lighting element Lk preferentially over the similar single color lighting element Lc ( S900 ).

[0335] As described above, if the accommodated shoe is configured to be non-colorful, the second lighting element 420 reflecting color may not match well therewith, and thus it may be preferred to recommend the similar color temperature lighting element Lk over the similar monochromatic lighting element Lc.

[0336] On the other hand, if the accommodated shoes are configured in color, the second lighting 420 may be recommended by presenting a similar monochromatic lighting Lc closest to the primary color and then presenting a similar color temperature lighting Lk.

[0337] As described above, in the display device 1 according to the present embodiment, since the similar color temperature lighting element Lk is recommended in preference to the similar monochrome lighting element Lc when the image of the shoe is non-color, the second lighting element 420 having the color temperature closest to the shoe image can be selected instead of matching the color of the shoe image.

[0338] In the display apparatus 1 according to an embodiment of the present disclosure, the controller 600 may recommend the similar spectrum lighting element Ls regardless of the priority between the similar monochromatic lighting element Lc and the similar color temperature lighting element Lk.

[0339] As described above, depending on whether the accommodated shoe image is achromatic, one of the similar color temperature lighting element Lk and the similar monochromatic lighting element Lc may be preferentially recommended.

[0340] However, beyond this, there may be situations where similar spectrum lighting Ls better reflects the characteristics of the shoe, such as when the image of the shoe being accommodated does not have a distinct color in a particular family.

[0341] Therefore, in order to provide the user with more diverse choices, the second lighting element 420 may be recommended by presenting the similar spectrum lighting element Ls separately from the similar monochromatic lighting element Lc and the similar color temperature lighting element Lk.

[0342] As described above, since the presentation device 1 according to the present embodiment recommends similar spectrum lighting elements Ls independently of the priority between similar monochromatic lighting elements Lc and similar color temperature lighting elements Lk to be recommended, more diverse choices can be provided to users who wish to select the type of the second lighting element 420.

[0343] The following will be based on Fig.13 The second lighting element 420 shown is used to describe the recommended order of the above-mentioned second lighting element 420.

[0344] First, in Fig.13 In the case of (a), similar color temperature lighting components Lk are recommended first, and then similar monochromatic lighting components Lc may be sequentially recommended. In addition, similar spectrum lighting components Ls may be sequentially recommended regardless of the above.

[0345] In addition, Fig.13 In the case of (b), the similar monochromatic lighting element Lc closest to the primary color may be recommended first, and then the similar color temperature lighting element Lk and the remaining similar monochromatic lighting elements Lc may be recommended sequentially. In addition, the similar spectrum lighting elements Ls may be recommended sequentially regardless of the above.

[0346] In addition, Fig.13 In the case of (c), similar color temperature lighting components Lk may be recommended first, and then similar monochromatic lighting components Lc may be recommended sequentially. In addition, similar spectrum lighting components Ls are recommended sequentially, regardless of the above, so that rainbow-type similar spectrum lighting components Ls are preferentially recommended.

[0347] Although the example of the second lighting member 420 to be recommended has been described above, the present disclosure is not necessarily limited to Fig.13 those shown, and various combinations of second lighting elements 420 may be recommended depending on the characteristics of the accommodated shoes and the user's preferences.

[0348] In the above, the specific embodiments of the present disclosure are described and shown, but the present invention is not limited to the disclosed embodiments, and those skilled in the art can understand that various modifications can be made to the embodiments and converted into another specific embodiment without departing from the spirit and scope of the present invention. Therefore, the scope of the present disclosure will not be limited by the described embodiments, but by the technical spirit disclosed in the claims.

[0349] Industrial Applicability

[0350] According to at least one of the embodiments of the present disclosure, since the display device is configured to accommodate an object in a accommodating space formed by a main body and a mobile body, and then switch to a closed state to display the object, and is simultaneously configured to circulate air in the accommodating space through a blowing part to control the state of the accommodating space, an object display effect and an object management effect can be effectively achieved.

[0351] In addition, according to at least one of the embodiments of the present disclosure, since the first lighting element intensively illuminates the area where the object is placed and since the second lighting element illuminates the rear surface of the accommodating space, the internal effect of the space accommodating the object can be improved while maximizing the display effect of the object.

[0352] In addition, according to at least one of the embodiments of the present disclosure, since the controller recommends to the user the second lighting element that best matches the object image input into the input part, the user can more easily select the type of the second lighting element, and the aesthetics can be improved by the second lighting element that reflects the characteristics of each object.

[0353] In addition, according to at least one of the embodiments of the present disclosure, since the object image is input through the portable device and since the type of the second lighting component to be recommended is displayed based on it through the portable device, it is more convenient to input the object image and identify the type of the second lighting component to be recommended.

[0354] In addition, according to at least one of the embodiments of the present disclosure, since reference lines are displayed when capturing an image of an object through a portable device, images can always be captured to have a similar composition even if the photographers are different, thereby enabling more accurate input of images for recommending a second lighting device.

[0355] Furthermore, according to at least one of the embodiments of the present disclosure, even if the capture time and surrounding environment of the object image vary, an image for recommending the second lighting element can be more accurately input by always capturing the image in a similar state.

[0356] In addition, according to at least one of the embodiments of the present disclosure, since the dummy area is removed when capturing an object image using a portable device, parts of the image that do not need to be reflected when recommending the second lighting component can be excluded, so that the recommendation of the second lighting component can be performed more effectively.

[0357] In addition, according to at least one of the embodiments of the present disclosure, since at least one of similar color temperature lighting elements, similar monochromatic lighting elements, and similar spectrum lighting elements is recommended to the user from the preset lighting elements, the recommendation can be made in various ways to reflect the accommodated objects, thereby improving the user's utilization of the second lighting element.

[0358] Furthermore, according to at least one of the embodiments of the present disclosure, since similar color temperature lighting elements that match well with pixels having relatively high brightness in the object image are recommended, a second lighting element having a color temperature most similar to the object image may be recommended.

[0359] In addition, according to at least one of the embodiments of the present disclosure, since a similar monochromatic lighting element that matches well with pixels with relatively high chromaticity in an object image is recommended, a second lighting element can be recommended that reflects a tendency to give more weight to colors with higher chromaticity than to actual colors when identifying an object.

[0360] Furthermore, according to at least one of the embodiments of the present disclosure, since a color palette obtained by amplifying pixels with higher chromaticity in an object image and classifying them into clusters is utilized, a second lighting device can be recommended by utilizing analysis that emphasizes colors with higher chromaticity.

[0361] Furthermore, according to at least one of the embodiments of the present disclosure, since similar monochromatic lighting elements are recommended in an order that matches well with the color having the highest proportion in the color palette derived as multiple clusters, the recommendation order of the second lighting elements can be determined in an order similar to the color of the object.

[0362] In addition, according to at least one of the embodiments of the present disclosure, since similar spectral lighting components in a spectral state are recommended in an order that matches well with the color having the highest proportion in a color palette derived as multiple clusters, the recommended order of the second lighting components in the spectral state can be determined in an order similar to the color of the object.

[0363] In addition, according to at least one of the embodiments of the present disclosure, since the display device is configured to determine whether the object image has multiple colors by deriving the Euclidean distance between three colors with relatively high distribution in the color palette as multiple clusters, the second lighting device can be recommended by utilizing analysis reflecting the situation where the object has various colors.

[0364] In addition, according to at least one of the embodiments of the present disclosure, if the object image has various colors or if the attributes of the color with the highest proportion in the color palette derived as multiple clusters are not different, a rainbow-type similar spectrum lighting piece is preferentially recommended, and thus a second lighting piece can be recommended to reflect the situation where there is no bias toward a specific color.

[0365] In addition, according to at least one of the embodiments of the present disclosure, since the display device is configured to determine whether the object image is non-color by deriving the attribute of the color with the highest proportion in the color palette of multiple clusters, the second lighting element can be recommended by utilizing analysis reflecting the situation where the object is non-color.

[0366] In addition, according to at least one of the embodiments of the present disclosure, since similar color temperature lighting elements are recommended preferentially over similar monochromatic lighting elements when the object image is non-color, a second lighting element having a color temperature closest to the object image can be selected instead of matching the color of the object image.

[0367] Furthermore, according to at least one of the embodiments of the present disclosure, since similar spectrum lighting components are recommended independently of the priority between similar monochromatic lighting components and similar color temperature lighting components to be recommended, more diverse choices can be provided to users who wish to select the type of second lighting components.
