Description

Technical Field

[0001] The present invention relates to a display device and a manufacturing method thereof; in particular, the present invention relates to a spliced ​​display device and a manufacturing method thereof. Background Art

[0002] In order to have a good sense of penetration, existing transparent display modules usually use a three-sided borderless design. However, in the case where such display modules use splicing technology to form a large-size display device, if a splicing mechanism is set on the back of the display module, it is easy to cause visual gaps and reduce the display quality. If the display modules are spliced ​​together using colloid, bubbles are often generated due to the small gap, which is not conducive to the flow of colloid, resulting in poor filling and reduced manufacturing yield. Furthermore, when rework is required, the display device spliced ​​with colloid requires large-scale removal of the colloid, making it difficult to disassemble the display module and may even damage the display module.

[0058] In the accompanying drawings, for the sake of clarity, the thickness of layers, films, panels, regions, etc. is magnified. Throughout the specification, the same reference numerals represent the same elements. It should be understood that when an element such as a layer, film, region or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or an intermediate element can also exist. On the contrary, when an element is referred to as being "directly on" or "directly connected to" another element, there is no intermediate element. As used herein, "connection" can refer to physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" can be other elements between two elements.

[0059] It should be understood that although the terms "first", "second", "third", etc. can be used to describe various elements, components, regions, layers and / or parts in this article, these elements, components, regions, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, the "first element", "component", "region", "layer" or "part" discussed below can be referred to as a second element, component, region, layer or part without departing from the teachings of this article.

[0060] The terms used herein are only for the purpose of describing specific embodiments and are not restrictive. As used herein, unless the content clearly indicates, the singular forms "one", "an" and "the" are intended to include plural forms, including "at least one". "Or" means "and / or". As used herein, the term "and / or" includes any and all combinations of one or more related listed items. It should also be understood that when used in this specification, the terms "include" and / or "include" specify the presence and / or parts of the features, regions, entireties, steps, operations, elements, but do not exclude the presence or addition of one or more other features, regions, entireties, steps, operations, elements, parts and / or their combinations.

[0061] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element, as shown in the figures. It should be understood that relative terms are intended to include different orientations of the device in addition to the orientation shown in the figures. For example, if the device in one figure is turned over, the element described as being on the "lower" side of the other elements will be oriented on the "upper" side of the other elements. Therefore, the exemplary term "lower" can include both "lower" and "upper" orientations, depending on the specific orientation of the figure. Similarly, if the device in one figure is turned over, the element described as being "below" or "below" other elements will be oriented as being "above" other elements. Therefore, the exemplary term "below" or "below" can include both above and below orientations.

[0062] As used herein, "about", "approximately", or "substantially" includes the stated value and the average value within an acceptable deviation range of the particular value determined by one of ordinary skill in the art, taking into account the measurement in question and the particular amount of error associated with the measurement (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, as used herein, "about", "approximately", or "substantially" can select a more acceptable deviation range or standard deviation depending on the optical property, etching property or other property, and can apply to all properties without a single standard deviation.

[0063] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and the present invention, and will not be interpreted as an idealized or overly formal meaning unless explicitly defined as such herein.

[0064] Exemplary embodiments are described herein with reference to cross-sectional views that are schematic diagrams of idealized embodiments. Therefore, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and / or tolerances, can be expected. Therefore, the embodiments described herein should not be construed as limited to the specific shapes of the regions as shown herein, but rather include shape deviations that result, for example, from manufacturing. For example, a region shown or described as flat may typically have rough and / or nonlinear features. In addition, the sharp angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0065] The present invention provides a display device. The display device of the present invention is a spliced ​​display device having a larger display surface by splicing technology. The details of the display device of the present invention will be described in detail below with reference to the drawings.

[0066] refer to Figures 1A to 1C , Figure 1A is an exploded perspective schematic diagram of a display device 1 according to an embodiment of the present invention; Figure 1B for Figure 1A A schematic three-dimensional diagram of the assembly of the display device 1; Figure 1C for Figure 1B A schematic top view of the second side 1b of the display device 1. Figures 1A to 1C As shown, the display device 1 includes two transparent display units 10, 20 and a detachable transparent combining member 30. Each transparent display unit 10, 20 includes a first substrate 12, 22, a second substrate 14, 24, and a display element 16, 26 disposed between the first substrate 12, 22 and the second substrate 14, 24. The detachable transparent combining member 30 is assembled between the two transparent display units 10, 20. On the first side 1a of the display device 1, a portion 30a of the detachable transparent combining member 30 protrudes from at least one of the first substrate 12, 22 and the second substrate 14, 24 of one of the two transparent display units 10, 20.

[0067] Specifically, the display device 1 has a first side 1a and a second side 1b opposite to the first side 1a. For example, the first side 1a and the second side 1b of the display device 1 may be the upper side and the lower side of the display device 1 in the vertical direction, respectively. The two transparent display units 10 and 20 are arranged side by side along the horizontal direction of the display device 1, so that the display surfaces of the two transparent display units 10 and 20 face the same direction. The detachable transparent combining member 30 is combined with the adjacent sides of the two transparent display units 10 and 20 along the vertical direction of the display device 1.

[0068] The transparent display unit 10 includes a first substrate 12, a second substrate 14, and a display element 16 disposed between the first substrate 12 and the second substrate 14. Similarly, the transparent display unit 20 includes a first substrate 22, a second substrate 24, and a display element 26 disposed between the first substrate 22 and the second substrate 24. In this embodiment, the transparent display unit 10 and the transparent display unit 20 preferably have the same structure, but are not limited thereto. In other embodiments, the transparent display unit 10 and the transparent display unit 20 may have different structures. Depending on the actual application, any suitable transparent display unit can be used as the transparent display unit 10 and the transparent display unit 20 of the display device 1.

[0069] The first substrates 12, 22 and the second substrates 14, 24 of the transparent display units 10, 20 are preferably transparent substrates, and their materials may include, for example, glass, polymer, quartz, etc., to protect and support the display elements 16, 26. In one embodiment, the display elements 16, 26 may be composed of a plurality of light-emitting components and a circuit structure. The plurality of light-emitting components are preferably arranged in an array, and the circuit structure includes a plurality of scanning lines and a plurality of data lines to drive the plurality of light-emitting components to form a plurality of pixel units. The light-emitting component may include a light-emitting diode (such as a micro light-emitting diode), but is not limited thereto. Furthermore, if Figure 1C As shown, the display element 16 can be bonded and fixed between the first substrate 12 and the second substrate 14 by optical adhesive 18 to form the display unit 10 , and the display element 26 can be bonded and fixed between the first substrate 22 and the second substrate 24 by optical adhesive 28 to form the display unit 20 .

[0070] In addition, in one embodiment, at the first side 1a of the display device 1, the first substrate 12, 22 of one of the two transparent display units 10, 20 is retracted relative to the second substrate 14, 24. Figure 1A and Figure 1B As shown, on the second side 1b of the display device 1, the edge of the first substrate 12 of the transparent display unit 10 is preferably flush with the edge of the second substrate 14, and on the first side 1a of the display device 1, the first substrate 12 of the transparent display unit 10 is retracted relative to the second substrate 14, and the electrical connection portion 162 of the display element 16 is exposed. Similarly, on the second side 1b of the display device 1, the edge of the first substrate 22 of the transparent display unit 20 is preferably flush with the edge of the second substrate 24, and on the first side 1a of the display device 1, the first substrate 22 of the transparent display unit 20 is retracted relative to the second substrate 24, and the electrical connection portion 262 of the display element 26 is exposed. Specifically, in the extension direction of the adjacent sides of the transparent display units 10 and 20 (for example, the vertical direction of the display device 1), the size of the second substrates 14 and 24 is preferably larger than the first substrates 12 and 22, so that the first substrates 12 and 22 do not completely cover the second substrates 14 and 24 on the first side 1a of the display device 1, thereby exposing the electrical connection portions 162 and 262 of the display elements 16 and 26, which is helpful for the subsequent connection with the circuit board 50 (displayed on the display device 1) of the display device 1. Figure 3D , which will be described in detail later).

[0071] Furthermore, if Figure 1BAs shown, since the first substrate 12 of the transparent display unit 10 is retracted relative to the second substrate 14, the portion 30a of the detachable transparent binder 30 protrudes from the retracted first substrates 12 and 22, but the invention is not limited thereto. In another embodiment, the first substrates 12 and 22 and the second substrates 14 and 24 may have the same size, for example, the edges of the first substrates 12 and 22 and the edges of the second substrates 14 and 24 are all flushly arranged on the first side 1a and the second side 1b of the display device 1, so that the portion 30a of the detachable transparent binder 30 protrudes from the first substrates 12 and 22 and the second substrates 14 and 24 at the same time. In one embodiment, the length of the portion 30a of the detachable transparent binder 30 protruding from the first substrates 12 and 22 is preferably about 5.0 mm, but the invention is not limited thereto. According to actual applications, the length of the portion 30a of the detachable transparent binder 30 protruding may be greater than or less than 5.0 mm. By designing that the portion 30a of the detachable transparent combining member 30 protrudes from at least one of the first substrate 12, 22 and the second substrate 14, 24, the display device 1 of the present invention can be held or clamped by the protruding portion 30a during heavy work, thereby improving the convenience of disassembling the transparent display units 10, 20.

[0072] In one embodiment, Figure 1A and Figure 1C As shown, in the overlapping area of ​​the first substrate 12, 22 and the second substrate 14, 24, the size of the display element 16, 26 is preferably smaller than the size of the first substrate 12, 22 and the second substrate 14, 24, so that the transparent display unit 10, 20 forms a gap area 15, 25 surrounding the display element 16, 26 between the first substrate 12, 22 and the second substrate 14, 24. The gap area 15, 25 is preferably arranged along the periphery of the transparent display unit 10, 20 to form a "ㄇ"-shaped gap area 15, 25. In other words, the gap area 15, 25 is arranged on other sides except the first side 1a, such as the second side 1b and the adjacent two sides of the second side 1b. The gap regions 15 and 25 on the adjacent sides of the two transparent display units 10 and 20 can be used as the accommodating space for the detachable transparent combining member 30, and the remaining portions of the gap regions 15 and 25 can be used as the filling space for the subsequent filling of the sealing body, thereby allowing the display device 1 to form a large "ㄇ"-shaped sealing body 70 (shown in FIG. 1 ) with a width of about 2 times the width of the gap regions 15 and 25. Figure 3E , described in detail later).

[0073] The detachable transparent binder 30 is preferably prefabricated by molding or injection molding of a material having a hardness slightly less than that of the first substrate 12, 22 and the second substrate 14, 24. For example, the material of the detachable transparent binder 30 may include rubber, polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene (PS), or polyethylene terephthalate (PET), but is not limited thereto. The transparency of the detachable transparent binder 30 is preferably above 80%, and the reflectivity (SCI) of the detachable transparent binder 30 is preferably below 5%. In addition, the deformation temperature and melting temperature of the detachable transparent binder 30 are preferably above 90°C and above 150°C, respectively. Any material that enables the detachable transparent binder 30 to have the above-mentioned properties is suitable for making the detachable transparent binder 30.

[0074] like Figures 1A to 1C As shown, in this embodiment, the detachable transparent binder 30 may have a limiting portion 32. The limiting portion 32 is preferably arranged along the length direction of the detachable transparent binder 30 and protrudes from the detachable transparent binder 30. Specifically, the detachable transparent binder 30 has a flat strip body extending along the adjacent sides of the two transparent display units 10 and 20. The limiting portion 32 preferably extends vertically outward from the surface of the flat strip body to separate the flat strip body of the detachable transparent binder 30 into wing portions 34a and 34b along the length direction of the detachable transparent binder 30. When the detachable transparent binder 30 is combined between the two transparent display units 10 and 20, the wing portions 34a and 34b are respectively inserted into the adjacent gap areas 15 and 25 of the two transparent display units 10 and 20, so that the adjacent sides of the two transparent display units 10 and 20 contact the opposite sides of the limiting portion 32 respectively. In this embodiment, the stopper 32 may be disposed on two opposite surfaces of the detachable transparent combining member 30, so that the detachable transparent combining member 30 has a "cross" shaped cross-section. When the detachable transparent combining member 30 is assembled between the two transparent display units 10, 20, the first substrates 12, 22 may contact the opposite sides of the stopper 32 on the upper surface, for example, respectively, and the second substrates 14, 24 may contact the opposite sides of the stopper 32 on the lower surface, for example, respectively, but not limited thereto. In another embodiment, the detachable transparent combining member 30 may have a "T" shaped cross-section, so that only one of the first substrates 12, 22 and the second substrates 14, 24 (for example, the first substrates 12, 22) contacts the opposite sides of the stopper 32, and a gap is formed between the first substrates 12, 22 and the second substrates 14, 24 (for example, the second substrates 14, 24). In yet another embodiment, the detachable transparent combining member 30 may have a "I"-shaped cross-sectional shape (that is, the detachable transparent combining member 30 does not have the limiting portion 32), so that the first substrates 12 and 22 may contact or not contact each other, and the second substrates 14 and 24 may contact or not contact each other.

[0075] In one embodiment, Figure 1C As shown, the thickness T of the transparent display units 10, 20 (i.e., the distance from the outer surface of the first substrate 12, 22 to the outer surface of the second substrate 14, 24) may be approximately 3.9 mm. The distance D1 or D2 from the display element 16, 26 of the transparent display units 10, 20 to the edge of the first substrate 12, 22 (or the second substrate 14, 24) (i.e., the width of the gap area 15, 25 in the horizontal direction) may be approximately 3.0 mm. The distance D3 between the two transparent display units 10, 20 may be approximately 1.0 mm. The distance D4 from the display element 16 to the edge of the optical adhesive 18 may be approximately 0.3 mm. The distance D5 between the first substrate 12, 22 and the second substrate 14, 24 of the transparent display units 10, 20 (i.e., the thickness of the gap area 15, 25) may be approximately 1.3 mm. Depending on the actual application, the above thicknesses or distances may have different values, and are not limited to the values ​​shown. From another point of view, the dimension of the stopper 32 of the detachable transparent connector 30 in the short axis (width) direction substantially defines the distance D3 between the two transparent display units 10, 20, and the protruding height (i.e., thickness) of the stopper 32 preferably corresponds to the top surface of the first substrate 12, 22, so that the stopper 32 and the first substrate 12, 22 are substantially coplanar after assembly. The dimension of the wing portions 34a and 34b in the short axis (width) direction is preferably smaller than the distance between the edge of the optical adhesive 18, 28 and the first substrate 12, 22 (or the second substrate 14, 24), for example, D1 (or D2) minus D4. The dimension of the wing portions 34a and 34b in the thickness direction is preferably equal to or slightly larger than the distance D5 between the first substrate 12, 22 and the second substrate 14, 24, so that the wing portions 34a and 34b of the detachable transparent connector 30 can be respectively tightly fitted in the gap areas 15, 25.

[0076] refer to Figure 2 , Figure 2 FIG. 1 is a partial plan view of a second side (eg, 1b) of a display device (eg, display device 1) according to an embodiment of the present invention. Figure 2As shown, on the second side 1b of the display device 1, the detachable transparent binder 30 can be retracted relative to the two transparent display units 10, 20 to form a glue filling space SP between the two transparent display units 10, 20 and the detachable transparent binder 30. In one embodiment, the corners of the transparent display units 10, 20 can be in the form of arc-shaped chamfers to increase the size of the glue filling space SP and improve the glue filling margin, but it is not limited to this. In other embodiments, the corners of the transparent display units 10, 20 can be in the form of right angles or truncated angles. In one embodiment, the distance G of the retracted detachable transparent binder 30 (that is, the distance between the detachable transparent binder 30 and the edge of the display device 1 on the second side 1b) is preferably greater than 1.0 mm and less than 5.0 mm, but it is not limited to this. The distance G of the retracted detachable transparent binder 30 can vary according to the properties of the sealant (such as adhesion, fluidity, etc.) and the process of coating the sealant.

[0077] In another embodiment, the present invention also provides a method for manufacturing the display device 1. Figure 1A and Figure 1B The manufacturing method of the display device 1 includes: providing two transparent display units 10, 20, each transparent display unit 10, 20 including a first substrate 12, 22, a second substrate 14, 24 and a display element 16, 26 disposed between the first substrate 12, 22 and the second substrate 14, 24; and assembling a detachable transparent combining member 30 between the two transparent display units 10, 20, so that on a first side 1a of the display device 1, a portion 30a of the detachable transparent combining member 30 protrudes from at least one of the first substrate 12, 22 and the second substrate 14, 24 of one of the two transparent display units 10, 20.

[0078] Corresponds to Figure 2 The step of assembling the detachable transparent combining member 30 between the two transparent display units 10 and 20 may include: on the second side 1b of the display device 1, retracting the detachable transparent combining member 30 relative to the two transparent display units 10 and 20 to form a glue filling space SP between the two transparent display units 10 and 20 and the detachable transparent combining member 30.

[0079] Furthermore, in one embodiment, if FIG. 3A to FIG. 3E As shown, the display device 1 may further include a base 40, a circuit board 50, a cover 60 and a sealing body 70. FIG. 3A to FIG. 3E The details of the base 40 , the circuit board 50 , the cover 60 and the sealing body 70 of the display device 1 and the corresponding manufacturing method of the display device 1 are described.

[0080] like FIG. 3A to FIG. 3CAs shown, the display device 1 further includes a base 40. The base 40 is used to integrate the components of the display device 1, and is combined with the cover plate 60 so that the display device 1 has an integrated and simple appearance. In this embodiment, the step of assembling the detachable transparent combination member 30 between the two transparent display units 10 and 20 may include: setting one of the two transparent display units 10 and 20 on the base 40; inserting a part of the detachable transparent combination member 30 into one side of the two transparent display units 10 and 20; and setting the other of the two transparent display units 10 and 20 on the base 40, and inserting another part of the detachable transparent combination member 30 into one side of the other of the two transparent display units 10 and 20.

[0081] Specifically, if Figure 3A As shown, in this embodiment, the transparent display unit 10 is partially disposed on the base 40, so that the side of the transparent display unit 10 having the electrical connection portion 162 is disposed above the base 40. In one embodiment, the base 40 may have a receiving groove 42 for accommodating and positioning the transparent display units 10, 20 and the detachable transparent combining member 30. For example, when the transparent display unit 10 is disposed on the base 40, the left side of the transparent display unit 10 may be abutted against the left side of the receiving groove 42, thereby achieving the positioning of the transparent display unit 10 in the horizontal direction. In addition, the lower edge of the second substrate 14 of the transparent display unit 10 may be abutted against the wall surface of the receiving groove 42 extending along the horizontal direction, thereby achieving the positioning of the transparent display unit 10 in the vertical direction. Afterwards, the detachable transparent combining member 30 is moved from the right side to the left side of the transparent display unit 10, so as to insert the wing portion 34a of the detachable transparent combining member 30 into the gap area 15 located on the right side between the first substrate 12 and the second substrate 14 of the transparent display unit 10, so as to complete the above-mentioned steps. Figure 3B The assembly stage shown on the left. In this assembly stage, the lower edge of the detachable transparent connector 30 preferably abuts against the wall of the receiving groove 42 extending in the horizontal direction, so as to achieve the vertical positioning of the detachable transparent connector 30. In other words, in accordance with the length design of the detachable transparent connector 30, the distance G of the detachable transparent connector 30 retracted on the second side 1b of the display device 1 can be defined in this way. Figure 3B As shown in FIG. 1 , the transparent display unit 20 is moved from the right side to the left side of the detachable transparent combining member 30, so that the wing portion 34b of the detachable transparent combining member 30 is inserted into the gap area 25 located on the left side between the first substrate 22 and the second substrate 24 of the transparent display unit 20, so as to complete the operation as shown in FIG. Figure 3C In this assembly stage, the two transparent display units 10, 20 and the detachable transparent combination member 30 are partially disposed on one side of the base 40 in a combined manner, and the portion 30a of the detachable transparent combination member 30 protruding from the first substrate 12, 22 is adjacent to the base 40 and overlapped on the base 40. Furthermore, a second side 1b of the display device 1 may be defined as follows: Figure 2 The fill space SP is shown.

[0082] like Figure 3C and Figure 3D As shown, the display device 1 further includes a circuit board 50. The circuit board 50 is disposed on the base 40 and electrically connects the two transparent display units 10 and 20. Specifically, the circuit board 50 is electrically connected to the electrical connection parts 162 and 262 of the display elements 16 and 26, so as to achieve electrical control of the transparent display units 10 and 20 by the display device 1. Figure 3C The manufacturing method of the display device 1 further includes the step of disposing a circuit board 50 on the base 40 so that the circuit board 50 is electrically connected to the two transparent display units 10 and 20 .

[0083] like Figure 3D and Figure 3E As shown, the display device 1 further includes a cover plate 60, and the cover plate 60 is preferably combined with the base 40. For example, the cover plate 60 can be fixed to the base 40 by means of screws, a locking mechanism, etc. The cover plate 60 is disposed on the first side 1a of the display device 1 and covers the circuit board 50. The cover plate 60 preferably further partially covers the first substrate 12, 22 to enhance the appearance of the display device 1. Figure 3D The manufacturing method of the display device 1 further includes a step of disposing a cover plate 60 to be combined with the base 40 .

[0084] like Figure 3E As shown, the display device 1 further includes a sealant 70, which is preferably transparent. The material of the sealant 70 may include epoxy, latex, polyvinyl alcohol (PVA), etc. The sealant 70 is arranged along the edges of the two transparent display units 10 and 20, and the sealant 70 is not arranged on the first side 1a of the display device 1. For example, the sealant 70 is applied along the left side, the second side 1b and the right side of the display device 1, so that the sealant 70 has a "ㄇ" shape that is about twice the width of the transparent display units 10 and 20. In one embodiment, the sealant 70 is preferably located between the first substrate 12, 22 and the second substrate 14, 24 of each of the two transparent display units 10 and 20. For example, the sealant material is applied along the gap area 15 on the left and upper side of the transparent display unit 10, the filling space SP and the gap area 25 on the upper side and right side of the transparent display unit 20 and cured to form the sealant 70. In one embodiment, the encapsulant 70 is preferably completely located in the gap area 15 and the gap area 25, but the present invention is not limited thereto. In another embodiment, the encapsulant 70 may slightly overflow the gap areas 15 and 25 of the transparent display units 10 and 20. The encapsulant 70 can enhance the waterproof, dustproof, protective, and aesthetic effects of the display device 1.

[0085] Corresponds to Figure 3EThe manufacturing method of the display device 1 further includes disposing a sealing body 70 along the edges of the two transparent display units 10 and 20, and the sealing body 70 is not disposed on the first side 1a of the display device 1. Furthermore, the step of disposing the sealing body 70 includes: disposing the sealing body 70 in the filling space SP.

[0086] In the aforementioned embodiment, the detachable transparent coupling member 30 is positioned vertically by abutting against the receiving groove 42 of the base 40, but the present invention is not limited thereto. In other embodiments, the detachable transparent coupling member 30 may have a positioning portion, so that the positioning portion can also be positioned vertically by abutting against the substrate. FIG. 4A to FIG. 4C Schematic diagrams of positioning parts 36', 36", and 36'" of detachable transparent combining parts according to different embodiments of the present invention, corresponding to Figure 1B A partial enlarged view of area A. Figure 4A As shown, the detachable transparent combining member 30 may have a positioning portion 36'. The positioning portion 36' is disposed at a portion 30a' of the detachable transparent combining member 30 protruding from the first substrate 12, 22, and the positioning portion 36' protrudes from the detachable transparent combining member 30 to contact the side of at least one of the first substrate 12, 22 and the second substrate 22, 24 of one of the two transparent display units 10, 20. For example, the positioning portion 36' extends from the limiting portion 32, and the width of the positioning portion 36' is greater than the width of the limiting portion 32. During assembly, the lower right side of the first substrate 12 and the lower left side of the first substrate 22 may respectively abut against the positioning portion 36' to achieve the vertical positioning of the transparent display units 10, 20. In this embodiment, the positioning portion 36' is a strip-shaped protrusion disposed along the vertical (or length) direction, but is not limited thereto. In another embodiment, as Figure 4B As shown, the positioning portion 36" is disposed on the portion 30a" of the detachable transparent combining member 30 protruding from the first substrate 12, 22, and the positioning portion 36" is a strip-shaped protrusion disposed along the horizontal (or width) direction. In another embodiment, as Figure 4C As shown, the positioning portion 36 ′″ is disposed on a portion 30 a ′″ of the detachable transparent combining member 30 protruding from the first substrates 12 and 22 , and the positioning portion 36 ′″ is a block-shaped protrusion.

[0087] Furthermore, the manufacturing method of the display device 1 of the present invention further includes a reworking step, wherein the reworking step can refer to FIG. 3A to FIG. 3E The assembly steps are reversed, for example, the cover plate 60 and the circuit board 50 are removed in sequence, which will not be described in detail. The following focuses on the disassembly of the two transparent display units 10, 20 and the detachable transparent combination member 30. FIG. 5A to FIG. 5D , which is similar to Figure 21 is a partial plan view of the second side 1b of the display device 1. Here, for the sake of convenience, the encapsulant 70 is exaggeratedly shown as protruding from the transparent display units 10 and 20. In practice, the encapsulant 70 may be completely located in the gap areas 15 and 25 of the transparent display units 10 and 20 or slightly overflow the gap areas 15 and 25 of the transparent display units 10 and 20. Figure 5A As shown, the encapsulant 70 is disposed along the side of the transparent display unit 10 to fill the encapsulation space SP, and is disposed along the side of the transparent display unit 20 so that the two transparent display units 10 and 20 are bonded to each other through the encapsulant 70 in the encapsulation space SP.

[0088] like Figure 5B As shown, the reworking step includes: removing a portion of the encapsulant 70 on the second side 1b of the display device 1 to expose at least the filler space SP. Specifically, in this step, the encapsulant 70 in the filler space SP is removed so that the two transparent display units 10 and 20 have no portion bonded by the encapsulant 70 on the second side 1b of the display device 1. At this time, the unremoved portions 70a and 70b of the encapsulant are retained on the two transparent display units 10 and 20, respectively.

[0089] Furthermore, the rework step includes: removing the two transparent display units 10 and 20 that need to be reworked from the detachable transparent combination 30. Specifically, since the two transparent display units 10 and 20 have no part bonded by the sealing glue 70 on the second side 1b of the display device 1, the part that needs to be reworked can be easily removed from the detachable transparent combination 30. Figure 5B As shown, if the transparent display unit 20 is damaged or defective, the transparent display unit 20 is moved outward (e.g., to the right) to separate the transparent display unit 20 from the right side of the detachable transparent combining member 30. Similarly, if the transparent display unit 10 is damaged or defective, the transparent display unit 10 is moved outward (e.g., to the left) to separate the transparent display unit 10 from the left side of the detachable transparent combining member 30.

[0090] like Figure 5CAs shown, the reworking step includes: assembling the replaced transparent display unit 20' to the detachable transparent combining member 30. In this embodiment, the transparent display unit 20' may have the same structure as the transparent display units 10 and 20, but is not limited thereto. For example, if the transparent display unit 20' replaces the transparent display unit 20, the transparent display unit 20' is moved from the right side to the left side of the detachable transparent combining member 30 so that a portion of the detachable transparent combining member 30 (such as the wing portion 34b of the aforementioned embodiment) is inserted into the gap area on the left side between the two substrates of the transparent display unit 20'. If the transparent display unit 20' replaces the transparent display unit 10, the transparent display unit 20' is moved from the left side to the right side of the detachable transparent combining member 30 so that a portion of the detachable transparent combining member 30 (such as the wing portion 34a of the aforementioned embodiment) is inserted into the gap area on the right side between the two substrates of the transparent display unit 20'. Thereby, a glue-filling space SP′ is formed between the transparent display unit 10 or 20 (the transparent display unit 10 in this embodiment), the transparent display unit 20 ′ and the detachable transparent combining member 30 .

[0091] like Figure 5D As shown, the reworking step includes: applying a reworked encapsulant 72 along the edge of the replaced transparent display unit 20', the reworked encapsulant 72 fills the filling space SP' and connects the unremoved portion of the encapsulant (e.g. 70a). For example, if the transparent display unit 20' replaces the transparent display unit 20, the reworked encapsulant 72 is applied along the gap area on the right and upper side of the transparent display unit 20', and the filling space SP' is filled with the reworked encapsulant 72, and the reworked encapsulant 72 is connected to the unremoved portion 70a of the encapsulant in the previous step on the transparent display unit 10. If the transparent display unit 20' replaces the transparent display unit 10, the reworked encapsulant 72 is applied along the gap area on the left and upper side of the transparent display unit 20', and the filling space SP' is filled with the reworked encapsulant 72, and the reworked encapsulant 72 is connected to the unremoved portion 70b of the encapsulant on the transparent display unit 20. After the rework is completed, the unremoved portion of the encapsulant (e.g., 70a or 70b) and the reworked encapsulant 72 form a connection interface that can be observed by the naked eye or an instrument. The reworked encapsulant 72 can use the same or different materials as the encapsulant 70, including, for example, epoxy, latex, polyvinyl alcohol (PVA), etc.

[0092] The manufacturing method of the display device 1 of the present invention further includes a disassembly step, wherein the disassembly step includes: removing a portion of the encapsulant 70 on the second side 1b of the display device 1 to expose at least the filling space SP, so that the two transparent display units 10 and 20 have no portion bonded by the encapsulant 70 on the second side 1b of the display device 1 (the details of which can be referred to the relevant description of the above-mentioned rework step, which will not be repeated here); removing one of the two transparent display units 10 and 20 from the detachable transparent combining member 30 (for example, removing the transparent display unit 20 from the right side outward); and removing the other of the two transparent display units 10 and 20 from the detachable transparent combining member 30 (for example, removing the transparent display unit 10 from the left side outward). Specifically, the step of removing the two transparent display units 10 and 20 can be performed by holding or clamping the portion 30a of the detachable transparent combining member 30 protruding from the first substrate 12 and 22 to apply force to gradually separate the detachable transparent combining member 30 and the transparent display units 10 and 20 from the first side 1a of the display device 1 toward the second side 1b.

[0093] The display device 1 and the manufacturing method thereof of the present invention combine the transparent display units 10 and 20 by means of the detachable combination 30, which effectively improves the convenience of splicing and disassembling of the display device 1. Furthermore, the display device 1 and the manufacturing method thereof of the present invention combine the transparent display units 10 and 20 by means of the detachable combination 30, which reduces the sealing glue bonded between the transparent display units 10 and 20, improves the convenience of heavy work or disassembly work, and reduces the possibility of damaging the transparent display units 10 and 20, so as to improve the reusability of the detachable combination 30 and the transparent display units 10 and 20, and achieve the effect of circular economy.

[0094] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and equivalent settings included in the spirit and scope of the claims are all included in the scope of the present invention.
