Description

Transparent display device using a light-emitting element

[0001] The present disclosure is applicable to the field of technology related to display devices and, for example, relates to a transparent display device using a light-emitting device.

[0002] Recently, display devices with excellent characteristics such as thinness and flexibility are being developed in the field of display technology. Currently, the major commercially available displays are represented by LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diodes).

[0003] Meanwhile, light-emitting diodes (LEDs) are semiconductor light-emitting devices well known for converting electric current into light. Starting with the commercialization of red LEDs using GaAsP compound semiconductors in 1962, they have been used as light sources for display images in electronic devices, including information and communication equipment, along with green LEDs of the GaP:N series.

[0004] Recently, these light-emitting diodes (LEDs) have been gradually miniaturized and manufactured into micrometer-sized LEDs, which are being used as pixels in display devices or as flat lighting.

[0005] Such Micro LED technology exhibits characteristics of low power consumption, high brightness, and high reliability compared to other display devices / panels, and can also be applied to flexible devices. Consequently, it has recently been actively researched by research institutions and companies.

[0006] Meanwhile, a transparent LED light source or display that can be configured transparently using LEDs is a display device in which an LED is composed of a light source or a single pixel.

[0007] Conventional transparent LED light sources or displays use LEDs in package form as light sources, and can configure both the electrodes and wiring patterns of the light source on a transparent film base surface or a strip-shaped circuit board.

[0008] Red, green, and blue LEDs and a control IC are arranged as a single pixel on the surface of a configured transparent film base or a strip-shaped circuit board, and each pixel is arranged on the film in a matrix form at regular intervals. The area excluding the light source and the control IC is entirely composed of a transparent material, and the transmittance is determined by the size of the light source and the size of the control IC.

[0009] Conventional transparent display devices were typically installed by attaching a transparent material, such as glass, to the front of the display. Consequently, there was a problem in that installation was difficult in locations where glass was unavailable. In particular, weight-sensitive wall-mounted or ceiling-hanging type display devices had limitations on the environments in which they could be installed because the total weight of the display device, including the glass, was large.

[0010] Furthermore, since the area occupied by the through-holes on the substrate is relatively small, there were limitations in terms of aperture ratio and transmittance, resulting in low efficiency and a problem of low visual immersion of the content.

[0011] Therefore, measures to resolve these problems are required.

[0012] The present disclosure aims to provide a transparent display device using a light-emitting element capable of improving aperture ratio and transmittance.

[0013] The present disclosure aims to provide a transparent display device using a light-emitting element that can enhance visual immersion by adding a sense of depth to the displayed content.

[0014] The present disclosure aims to provide a transparent display device using a light-emitting element that reduces weight by maximizing the penetration area, thereby enabling installation as a wall-mounted or ceiling-mounted hanging type.

[0015] The present disclosure aims to provide a transparent display device using a light-emitting element that is advantageous for securing flexibility and can be installed in a desired shape on an installation surface, such as a flat or curved surface.

[0016] The present disclosure aims to provide a transparent display device using a light-emitting element that can be utilized as an outdoor display.

[0017] A transparent display device according to one aspect of the present disclosure comprises: a substrate including a plurality of unit mounting portions; and a unit light source mounted on the unit mounting portions, wherein the substrate may include a connecting portion connected to both sides of the unit mounting portions; and a through hole including a first through hole located on a first side bordering the connecting portions and a second through hole located on a second side bordering the connecting portions.

[0018] A transparent display device according to another aspect of the present disclosure is a transparent display device configured by connecting a plurality of unit modules, wherein the unit module comprises a substrate including a plurality of unit mounting portions; and a unit light source mounted on the unit mounting portions, and the substrate comprises a connecting portion connected to both sides of the unit mounting portions; and a through hole including a first through hole located on a first side bordering the connecting portions and a second through hole located on a second side bordering the connecting portions, wherein the first through hole and the second through hole may surround at least one mounting portion and a connecting portion connected to the mounting portion on the front of the substrate.

[0019] First, the transparent display device according to the embodiment of the present disclosure can increase the aperture ratio and transmittance of the transparent display device by forming a through area through a through hole, excluding the minimum area required for mounting and driving a light source on the substrate.

[0020] Accordingly, when content is played, the surrounding background screen of the display is simultaneously displayed, adding a sense of depth to the content and enhancing visual immersion.

[0021] Meanwhile, the transparent display device according to the embodiment of the present disclosure has reduced weight through the maximization of the penetration area, and accordingly, can be installed as a wall-mounted or ceiling-mounted hanging type.

[0022] Meanwhile, the transparent display device according to the embodiment of the present disclosure is advantageous for securing flexibility, so it can be installed in a desired shape on an installation surface such as a flat or curved surface.

[0023] On the other hand, the transparent display device according to the embodiment of the present disclosure can be utilized as an outdoor display. In this case, the transparent display device may be installed outdoors by applying a material such as an adhesive to a substrate.

[0042]

[0043] FIG. 1 is a schematic plan view showing a transparent display device using a light-emitting element according to a first embodiment of the present disclosure.

[0044] Referring to FIG. 1, a transparent display device (10) may include a substrate (100) comprising a plurality of unit mounting portions (111a, 111b) and a unit light source (110) mounted on the unit mounting portions (111a or 111b; 111) of the substrate (100).

[0045] Such a substrate (100) may include connecting portions (112, 113, 114, 115) connected to both sides of a unit mounting portion (111a or 111b).

[0046] As an exemplary embodiment, the connecting portion may include a first connecting portion (112, 113, 114) connected in a first direction from a unit mounting portion (111a or 111b) and a second connecting portion (115) connected in a second direction from the first connecting portion (112, 113, 114).

[0047] Here, for example, the Y direction (vertical direction) in a conventional coordinate system is set as the first direction and the X direction (horizontal direction) is set as the second direction, but this is merely for illustrative purposes. Below, the configuration of the substrate (100) is described based on these first and second directions.

[0048] Meanwhile, the substrate (100) may have a rim portion (117, 118, 119) located on the outer side of the unit mounting portion (111) and the connecting portion (112, 113, 114, 115). This rim portion (117, 118, 119) may be considered as part of the connecting portion. For example, the rim portion (118, 119) in the second direction may correspond to the second connecting portion (115). As another example, the rim portion (117) in the first direction may correspond to the first connecting portion (112, 113, 114).

[0049] Here, the substrate (100) may be a printed circuit board (PCB). For example, the substrate (100) may be a printed circuit board equipped with circuit lines. Here, although the circuit lines are not specifically illustrated, they may be provided on at least some of the unit mounting portions (111a, 111b), connecting portions (112, 113, 114, 115), and border portions (117, 118, 119). For example, the circuit lines may be formed on the unit mounting portions (111a, 111b), connecting portions (112, 113, 114, 115), and border portions (117, 118, 119).

[0050] Referring to FIG. 1, as an exemplary embodiment, a substrate (100) may be configured with a plurality of unit modules (101, 102, 103, 104) that are joined together to expand the area. For example, FIG. 1 illustrates a substrate (100) in which four unit modules (101, 102, 103, 104) are connected to each other in one direction (second direction). However, this is an example, and it is understood that various numbers of unit modules can form various shapes. For example, a plurality of unit modules may be joined in a square or rectangular shape to form the substrate (100).

[0051] As described above, the substrate (100) may include a border portion (117, 118, 119) located on at least one side of the unit modules (101, 102, 103, 104). FIG. 1 illustrates an example where the border portion is not located between the unit modules, but alternatively, a first-direction border portion (117) may also be provided between the unit modules.

[0052] A connector (120) may be provided on at least a portion of these edge portions (117, 118, 119). As an exemplary embodiment, a connector (120) may be provided on one edge portion (119) of the edge portions (118, 119) connected in the second direction. For example, one such connector (120) may be provided for each connection portion (112, 113, 114) in the first direction. As another example, one such connector (120) may be provided for each unit module (101, 102, 103, 104).

[0053] A power circuit (200) that supplies power to a light source (110) mounted on a substrate (100) may be connected to the connector (120). Meanwhile, a controller (300) that drives the light source (110) to create a display and controls the power circuit (200) may be connected to the connector (120). For example, the controller (300) may create an image using unit light sources (110). The connector (120) and the power circuit (200) and / or the controller (300) may be connected to each other by a wire (121; conductor).

[0054] For example, a power circuit (200) and a controller (300) may be connected to each unit module (101, 102, 103, 104). A detailed description of such a power circuit (200) and a controller (300) is omitted below.

[0055] Here, the light source (110) may include a light-emitting element. For example, the unit light source (110) may include a light-emitting diode. For example, the unit light source (110) may be implemented as a light-emitting element package including a red light-emitting element, a green light-emitting element, and a blue light-emitting element. For example, the light source (110) may constitute a unit pixel in a display. In some cases, the light source (110) may include any one of a red light-emitting element, a green light-emitting element, and a blue light-emitting element. For example, the light source (110) may constitute a unit subpixel.

[0056] For example, the light source (110) may be configured to have a pixel having a mini LED with a size in the millimeter range or a micro LED with a size in the micrometer range as a subpixel. Such a light source (110) may be electrically connected to a circuit line formed on the substrate (100). For example, the light source (110) may be mounted and provided on the unit mounting portion (111a, 111b) of the substrate (100).

[0057] Referring to FIG. 1, the width of the connecting portions (112, 113, 114, 115) may be smaller than that of the mounting portion (111a or 111b). Accordingly, the distance between the connecting portions (112, 113, 114) adjacent in the second direction may be greater than the distance between the two mounting portions (111a or 111b) adjacent in the second direction.

[0058] A through hole (116) may be formed in an area of ​​the substrate (100) excluding the connecting portion (112, 113, 114, 115), the mounting portion (111a or 111b), and the edge portion (117, 118, 119). For example, the substrate (100) may include a through hole (116) comprising a first through hole (116a) located on the first side bordered by the connecting portion (112, 113, 114) and a second through hole (116b) located on the second side bordered by the connecting portion (112, 113, 114).

[0059] In this way, the first through hole (116a) or the second through hole (116b) may be defined by mounting portions (111a or 111b) adjacent to each other on both sides, a first connecting portion (112, 113, 114) connecting each unit mounting portion (111a or 111b) to each other in a first direction, and a second connecting portion (115) connecting from the first connecting portion (112, 113, 114) in a second direction. Meanwhile, the unit mounting portion (111a or 111b) may not be located on the edge side of the unit module (101, 102, 103, 104). Accordingly, the through hole (116k; hereinafter, third through hole) located on the edge side of the unit module (101, 102, 103, 104) may have a shape different from the first through hole (116a) or the second through hole (116b).

[0060] A transparent display device (10) equipped with such a substrate (100) may have a through hole (116) occupying a larger area. For example, the through hole (116) may be formed in an area excluding the connecting portion (112, 113, 114, 115), the mounting portion (111a or 111b), and the edge portion (117, 118, 119). Accordingly, the transparent display device (10) according to the embodiment of the present disclosure may have a light weight. Therefore, it may be possible to install it in a desired shape on a target surface. For example, the substrate (100) may be installed by attaching it to a target surface of various shapes and materials using an adhesive.

[0061] Conventional transparent display devices were typically installed by attaching a transparent material, such as glass, to the front of the display. Consequently, there was a problem in that installation was difficult in locations where glass was unavailable. In particular, weight-sensitive wall-mounted or ceiling-hanging type display devices had limitations on the environments in which they could be installed because the total weight of the display device, including the glass, was large.

[0062] Furthermore, since the area occupied by the through-holes on the substrate is relatively small, there were limitations in terms of aperture ratio and transmittance, resulting in low efficiency and a problem of low visual immersion of the content.

[0063] However, the transparent display device (10) according to the embodiment of the present disclosure as described above can increase the aperture ratio and transmittance, which are the appeal points of the transparent display device, by forming a through area through a through hole (116) except for a minimum area required for mounting and driving a light source (110) on the substrate (100). Accordingly, when driving content, the background screen around the display is simultaneously displayed, adding a sense of depth to the content and increasing visual immersion.

[0064] Meanwhile, the transparent display device (10) according to the embodiment of the present disclosure has reduced weight through the maximization of the penetration area, and accordingly, can be installed as a wall-mounted or ceiling-mounted hanging type. Meanwhile, it is advantageous for securing flexibility, so it can be installed in a desired shape on an installation surface such as a flat or curved surface. On the other hand, the transparent display device (10) according to the embodiment of the present disclosure can be utilized as an outdoor display. In this case, the transparent display device (10) can be installed outdoors by applying a material such as an adhesive to a substrate (100).

[0065] Hereinafter, exemplary embodiments of such a transparent display device (10) will be described in detail.

[0066]

[0067] FIG. 2 is a plan view showing a unit module of a transparent display device using a light-emitting element according to a first embodiment of the present disclosure. FIG. 3 is a cross-sectional view taken along line A-A' of FIG. 2. FIG. 4 is a cross-sectional view taken along line B-B' of FIG. 2.

[0068] Referring to FIG. 2, a substrate (100) and a light source (110) are shown in the unit module (101) of a transparent display device using a light-emitting element according to the first embodiment of the present disclosure described with reference to FIG. 1.

[0069] As described above, the substrate (100) may include connecting portions (112, 113, 114, 115) connected to both sides of the unit mounting portion (111a or 111b). As an exemplary embodiment, the connecting portion may include a first connecting portion (112, 113, 114) connected in a first direction from the unit mounting portion (111a or 111b) and a second connecting portion (115) connected in a second direction from the first connecting portion (112, 113, 114).

[0070] The substrate (100) may have a rim portion (117, 118, 119) located on the outer side of the unit mounting portion (111a or 111b; 111) and the connecting portion (112, 113, 114, 115). This rim portion (117, 118, 119) may be considered as part of the connecting portion. For example, the rim portion (118, 119) in the second direction may correspond to the second connecting portion (115). As another example, the rim portion (117) in the first direction may correspond to the first connecting portion (112, 113, 114). Here, the connector (120) described above with reference to FIG. 1 is omitted.

[0071] A through hole (116) may be formed in an area of ​​the substrate (100) excluding the connecting portion (112, 113, 114, 115), the mounting portion (111a or 111b), and the edge portion (117, 118, 119). For example, the substrate (100) may include a through hole (116) comprising a first through hole (116a) located on the first side bordered by the connecting portion (112, 113, 114) and a second through hole (116b) located on the second side bordered by the connecting portion (112, 113, 114, 115).

[0072] In this way, the first through hole (116a) or the second through hole (116b) may be defined by mounting portions (111a or 111b) adjacent to each other on both sides, a first connecting portion (112, 113, 114) connecting each unit mounting portion (111a or 111b) to each other in a first direction, and a second connecting portion (115) connecting to the first connecting portion (112, 113, 114) in a second direction.

[0073] Referring to FIG. 2, at least two mounting portions (111a and 111b) may be included on one side for a single through hole (116a or 116b). In terms of the through hole, a single through hole (116a or 116b) may be defined by four mounting portions (111a and 111b) and connecting portions (112, 113, 114, 115) located on both sides.

[0074] In this way, the through hole (116a or 116b) may be located between adjacent connecting parts (112, 113, 114). For example, the through hole (116a or 116b) may be defined by two adjacent mounting parts (111a or 111b), two adjacent first connecting parts (112, 113, 114), and two adjacent second connecting parts (115).

[0075] The first connecting part may include a first-1 connecting part (112) connected between two adjacent unit mounting parts (111a and 111b) and a first-2 connecting part (113, 114) connected between the unit mounting part (111a or 111b) and the second connecting part (115). In this case, at least a portion of the first-2 connecting parts (113, 114) (in this case, 113) may be provided to cross the second connecting part (115).

[0076] By this arrangement, the first through hole (116a) and the second through hole (116b) may be formed to surround at least one mounting portion (111a or 111b) and a connecting portion (112, 113, 114, 115) connected to the mounting portion (111a or 111b) on the front of the substrate (100).

[0077] For example, two through holes (116a and 116b) may be formed to surround two mounting parts (111a and 111b) and connecting parts (112, 113, 114, 115) connected to these mounting parts (111a or 111b).

[0078] Here, the positions of the first through hole (116a) and the second through hole (116b) are arbitrarily assigned, and the first through hole (116a) and the second through hole (116b) may not be distinguishable from each other. Meanwhile, the shape of the third through hole (116k) facing the edge portion (117) may be different from the shape of the first through hole (116a) and the second through hole (116b).

[0079] Referring to FIGS. 3 and 4, the positional relationship between the mounting portion (111) and the light source (110) on the substrate (100) is illustrated. As illustrated, the width of the mounting portion (111) may be larger than the width of the connecting portion (112 or the edge portion (117)).

[0080] Here, the substrate (100) has a shape in which four mounting portions (111) are provided in the vertical direction (first direction), a second connecting portion (115) is provided between two mounting portions (111), and six mounting portions (111) are provided in the horizontal direction (second direction). However, the present disclosure is not limited to the number of such mounting portions (111) and the relative size of the connecting portions (112, 113, 114, 115).

[0081]

[0082] FIG. 5 is a plan view showing a unit module of a transparent display device using a light-emitting element according to a second embodiment of the present disclosure.

[0083] Referring to FIG. 5, the substrate (100a) may include connecting portions (113, 114, 115a) connected to both sides of the unit mounting portion (111a or 111b). As an exemplary embodiment, the connecting portions may include a first connecting portion (113, 114) connected in a first direction from the unit mounting portion (111a or 111b) and a second connecting portion (115a) connected in a second direction from the first connecting portion (113, 114).

[0084] The substrate (100a) may have a rim portion (117, 118, 119) located on the outer side of the unit mounting portion (111a or 111b; 111) and the connecting portion (113, 114, 115a). This rim portion (117, 118, 119) may be considered as part of the connecting portion. For example, the rim portion (118, 119) in the second direction may correspond to the second connecting portion (115a). As another example, the rim portion (117) in the first direction may correspond to the first connecting portion (113, 114). Here, the connector (120) described above with reference to FIG. 1 is omitted.

[0085] A through hole (116) can be formed in an area of ​​the substrate (100a) excluding the connecting portion (113, 114, 115), the mounting portion (111a or 111b), and the edge portion (117, 118, 119). For example, the substrate (100a) may include a through hole (116) comprising a first through hole (116c) located on the first side bordering the connecting portion (113, 114) and a second through hole (116d) located on the second side bordering the connecting portion (113, 114).

[0086] In this way, the first through hole (116c) or the second through hole (116d) may be defined by mounting portions (111a or 111b) adjacent to each other on both sides, a first connecting portion (113, 114) connecting each unit mounting portion (111a or 111b) to each other in a first direction, and a second connecting portion (115a) connecting from the first connecting portion (113, 114) in a second direction.

[0087] Referring to FIG. 5, a mounting portion (111a or 111b) may be included on one side for a through hole (116c or 116d). In terms of the through hole, a through hole (116c or 116d) may be defined by two mounting portions (111a and 111b) and connecting portions (113, 114, 115) located on both sides.

[0088] In this way, the through hole (116c or 116d) may be located between adjacent connecting parts (113, 114). For example, the through hole (116c or 116d) may be defined by two adjacent mounting parts (111a or 111b), two first connecting parts (113, 114) adjacent to each other in a second direction, and two second connecting parts (115a) adjacent to each other in a first direction.

[0089] The first connecting part may include a first-second connecting part (113, 114) connected between the unit mounting part (111a or 111b) and the second connecting part (115a). Such first-second connecting part (113, 114) may be provided to cross the second connecting part (115a).

[0090] By this arrangement, the first through hole (116c) and the second through hole (116d) may be formed to surround at least one mounting portion (111a or 111b) and a connecting portion (113, 114, 115a) connected to the mounting portion (111a or 111b) on the front of the substrate (100a).

[0091] For example, two through holes (116c and 116d) may be formed to surround one mounting part (111a or 111b) and a connecting part (113, 114, 115a) connected to the mounting part (111a or 111b).

[0092] Here, the positions of the first through hole (116c) and the second through hole (116d) are arbitrarily assigned, and the first through hole (116c) and the second through hole (116d) may not be distinguishable from each other. Meanwhile, in this embodiment, a mounting portion (111c) is also provided on the rim portion (117), so that the shape of the through hole (116c or 116d) facing the rim portion (117) may also be the same as the remaining through hole (116c or 116d).

[0093] The substrate (100a) has a shape in which four mounting portions (111) are provided in the vertical direction (first direction), a second connecting portion (115a) is provided between two mounting portions (111), and six mounting portions (111) are provided in the horizontal direction (second direction). However, the present disclosure is not limited to the number of such mounting portions (111) and the relative size of the connecting portions (113, 114, 115a).

[0094] Parts not described herein may be similarly applied to the description of the first embodiment described above.

[0096] FIG. 6 is a plan view showing a unit module of a transparent display device using a light-emitting element according to a third embodiment of the present disclosure. FIG. 7 is a cross-sectional view along line C-C' of FIG. 6. FIG. 8 is a cross-sectional view along line D-D' of FIG. 6. FIG. 9 is a cross-sectional view along line E-E' of FIG. 6.

[0097] Referring to FIG. 6, the substrate (100b) may include connecting portions (112a, 115b, 115c, 115d) connected to both sides of a unit mounting portion (111c or 111d). As an exemplary embodiment, the connecting portion may include a first connecting portion (112a) connected in a first direction from the unit mounting portion (111c or 111d) and a second connecting portion (115b, 115c, 115d) connected in a second direction from the first connecting portion (112a).

[0098] This embodiment illustrates an example in which at least two unit mounting parts (111c and 111d; 111) are provided in a second direction. That is, according to this embodiment, the connecting part may be provided with a second connecting part (115b, 115c, 115d) that connects the two unit mounting parts (111c and 111d; 111) to each other in a second direction. At least some of these second connecting parts (115b, 115c, 115d) may intersect with a first connecting part (112a) that is connected in a first direction.

[0099] For example, the second connecting part may include a second-1 connecting part (115b) connected between two adjacent unit mounting parts (111c and 111d) and a second-2 connecting part (115c, 115d) connected between the unit mounting part (111c or 111d) and the first connecting part (112a). In this case, at least a portion of the second-2 connecting part (115c, 115d) may cross the first connecting part (112a).

[0100] Meanwhile, in this embodiment, the unit mounting portions (111c and 111d) may have a shape inclined with respect to the first direction or the second direction. For example, the unit mounting portions (111c and 111d) may have an inclined direction (F) that is not perpendicular to the first direction or the second direction.

[0101] Figure 6 shows a partial shape of the substrate (100b), but the edge portions (117, 118, 119) described above may be provided.

[0102] In the substrate (100b), a region excluding the connecting portion (112a, 115b, 115c, 115d) and the mounting portion (111c or 111d) may form a through hole (116; 116e or 116f). For example, the substrate (100b) may include a first through hole (116e) located on the first side bordered by the connecting portion (115b, 115c, 115d; second connecting portion) and a second through hole (116f) located on the second side bordered by the connecting portion (115b, 115c, 115d; second connecting portion).

[0103] In this way, the first through hole (116e) or the second through hole (116f) may be defined by mounting portions (111c or 111d) adjacent to each other on both sides, a second connecting portion (115b, 115c, 115d) connecting each unit mounting portion (111c or 111d) in a second direction, and a first connecting portion (112a) connecting each unit mounting portion (111c or 111d) to each other in a first direction.

[0104] Referring to FIG. 6, two mounting portions (111c and 111d) may be included on one side for a single through hole (116e or 116f). In terms of the through hole, a single through hole (116e or 116f) may be defined by four mounting portions (111c and 111d) and connecting portions (112a, 115b, 115c, 115d) located on both sides.

[0105] In this way, the through hole (116e or 116f) may be located between adjacent second connecting parts (115b, 115c, 115d). For example, the through hole (116e or 116f) may be defined by two mounting parts (111c or 111d) adjacent to each other, two first connecting parts (112a) adjacent to each other in a second direction, and two second connecting parts (115b, 115c, 115d) adjacent to each other in a first direction.

[0106] By this arrangement, the first through hole (116e) and the second through hole (116f) may be formed to surround at least one mounting portion (111c or 111d) and a connecting portion (112a, 115b, 115c, 115d) connected to the mounting portion (111c or 111d) on the front of the substrate (100b).

[0107] For example, two through holes (116e and 116f) may be formed to surround two mounting parts (111c and 111d) and connecting parts (112a, 115b, 115c, 115d) connected to these mounting parts (111c and 111d).

[0108] Here, the positions of the first through hole (116e) and the second through hole (116f) are arbitrarily assigned, and such first through hole (116e) and second through hole (116f) may not be distinguishable from each other.

[0109] In this embodiment, the substrate (100b) shows an example in which two mounting portions (111c and 111d) are provided in the horizontal direction between adjacent first connecting portions (112a).

[0110] Referring to FIGS. 7 through 9, the positional relationship between the mounting portion (111) and the light source (110) on the substrate (100b) is illustrated. As illustrated, the width of the mounting portion (111) may be greater than the width of the connecting portions (112a, 115b, 115c, 115d).

[0111] Referring to FIGS. 7 and 9, two adjacent through holes (116e and 116f) may be provided between the first connecting part (112a) in a second direction.

[0112] Any parts not described herein may be similarly applied to the description of the first or second embodiment described above.

[0113]

[0114] FIG. 10 is a plan view showing a unit module of a transparent display device using a light-emitting element according to a fourth embodiment of the present disclosure.

[0115] Referring to FIG. 10, the substrate (100c) may include connecting portions (112b, 115b, 115c, 115d) connected to both sides of a unit mounting portion (111c or 111d). As an exemplary embodiment, the connecting portion may include a first connecting portion (112b) connected in a first direction from the unit mounting portion (111c or 111d) and a second connecting portion (115b, 115c, 115d) connected in a second direction from the first connecting portion (112b).

[0116] This embodiment illustrates an example in which at least two unit mounting parts (111c and 111d; 111) are provided in a second direction. That is, according to this embodiment, the connecting part may be provided with a second connecting part (115b, 115c, 115d) that connects four unit mounting parts (111c and 111d; 111) to each other in a second direction. At least some of these second connecting parts (115b, 115c, 115d) may intersect with a first connecting part (112b) that is connected in a first direction.

[0117] For example, the second connecting part may include a second-1 connecting part (115b) connected between four adjacent unit mounting parts (111c and 111d) and a second-2 connecting part (115c, 115d) connected between the unit mounting part (111c or 111d) and the first connecting part (112b). In this case, at least a portion of the second-2 connecting part (115c, 115d) may cross the first connecting part (112b).

[0118] Meanwhile, in this embodiment, the unit mounting portions (111c and 111d) may have a shape inclined with respect to the first direction or the second direction. For example, the unit mounting portions (111c and 111d) may have an inclined direction (F) that is not perpendicular to the first direction or the second direction.

[0119] Figure 10 shows a partial shape of the substrate (100c), but the edge portions (117, 118, 119) described above may be provided.

[0120] In the substrate (100c), a through hole (116; 116g or 116h) may be formed in the area excluding the connecting portion (112b, 115b, 115c, 115d) and the mounting portion (111c or 111d). For example, the substrate (100c) may include a first through hole (116g) located on the first side bordered by the connecting portion (115b, 115c, 115d; second connecting portion) and a second through hole (116h) located on the second side bordered by the connecting portion (115b, 115c, 115d; second connecting portion).

[0121] In this way, the first through hole (116g) or the second through hole (116h) may be defined by mounting portions (111c or 111d) adjacent to each other on both sides, a second connecting portion (115b, 115c, 115d) connecting each unit mounting portion (111c or 111d) in a second direction, and a first connecting portion (112b) connecting each unit mounting portion (111c or 111d) to each other in a first direction.

[0122] Referring to FIG. 10, four mounting portions (111c and 111d) may be included on one side for a single through hole (116g or 116h). In terms of the through hole, a single through hole (116g or 116h) may be defined by eight mounting portions (111c and 111d) and connecting portions (112b, 115b, 115c, 115d) located on both sides.

[0123] In this way, the through hole (116g or 116h) may be located between adjacent second connecting parts (115b, 115c, 115d). For example, the through hole (116g or 116h) may be defined by eight adjacent mounting parts (111c or 111d), two first connecting parts (112b) adjacent to each other in a second direction, and two second connecting parts (115b, 115c, 115d) adjacent to each other in a first direction.

[0124] By this arrangement, the first through hole (116g) and the second through hole (116h) may be formed to surround at least one mounting portion (111c or 111d) and a connecting portion (112b, 115b, 115c, 115d) connected to the mounting portion (111c or 111d) on the front of the substrate (100c).

[0125] For example, two through holes (116g and 116h) may be formed to surround four mounting parts (111c and 111d) and connecting parts (112b, 115b, 115c, 115d) connected to these mounting parts (111c and 111d).

[0126] Here, the positions of the first through hole (116g) and the second through hole (116h) are arbitrarily assigned, and such first through hole (116g) and second through hole (116h) may not be distinguishable from each other.

[0127] In this embodiment, the substrate (100c) shows an example in which four mounting portions (111c and 111d) are provided in the horizontal direction between adjacent first connecting portions (112b).

[0128] For parts not described herein, the description of at least one of the first to third embodiments described above may be applied in the same way.
