Figure 4 This is a schematic cross-sectional view showing an embodiment of the watch device 1. Figure 4 It is along Figure 3 A schematic cross-sectional view of the line A-A'. Figure 5 This is a schematic perspective view showing an embodiment of the display panel (DP) and the circuit board portion (CBP).

[0041] Reference Figures 2 to 5 The watch device 1 can be a wearable electronic device. In an embodiment, for example, the watch device 1 may include a display component 100 and a watch strap component 200.

[0042] The display component 100 may include a display area DA to which the display panel DP (e.g., a display device) is applied, to provide image data including visual information via the display area DA along the display direction DR_D.

[0043] The watch strap component 200 can be set (e.g., mounted) on a user's wrist. The watch strap component 200 can be connected to the display component 100. The watch strap component 200 may include a wearing portion worn on the user's wrist and a connecting portion connecting one part of the watch strap component 200 to another part. The material of the watch strap component 200 is not limited to any particular example, and the watch strap component 200 can be worn on the wrist in a variety of ways.

[0044] The user can attach the watch device 1 to the user's wrist using the watch strap component 200. Therefore, the display component 100 can be provided on the user's wrist using the watch strap component 200, and the display component 100 can provide visual information to the user.

[0045] The display component 100 can have various shapes in a plan view. In an embodiment, for example, the display component 100 (or display area DA) can have a curved shape. The display component 100 (or display area DA) can have a circular or elliptical shape. In another embodiment, the display component 100 (or display area DA) can have a polygonal shape. The display component 100 (or display area DA) can have a quadrilateral shape, for example, a rectangular shape with rounded corners (e.g., a rounded rectangle).

[0046] For ease of explanation, an embodiment in which the display component 100 (or display area DA) has a circular shape will be described below.

[0047] In an embodiment, the display component 100 may include a lower substrate LB, a display panel DP, a circuit board portion CBP, and a cover window portion CV.

[0048] The lower substrate LB can form part of the housing of the display component 100. The lower substrate LB can be located on the lower part of the display panel DP (or circuit board portion CBP) where the cover window portion CV is not located. The lower substrate LB can include a rigid material (e.g., metal, plastic, etc.).

[0049] The display panel DP can emit light. The display panel DP can be disposed between the lower substrate LB and the cover window portion CV. The display panel DP can include various light sources. In embodiments, for example, the display panel DP can be an organic light-emitting panel including organic light-emitting elements or an inorganic light-emitting panel including inorganic light-emitting elements (e.g., micro light-emitting diodes (“LEDs”)). However, this disclosure is not limited to the specific examples.

[0050] The circuit board portion CBP can be disposed between the lower substrate LB and the display panel DP. The circuit board portion CBP can be disposed on the rear surface of the display panel DP. The circuit board portion CBP can be electrically connected to the wiring of the display panel DP via a connection portion COP electrically connected to pads (e.g., pad terminals) formed on a portion of the display panel DP.

[0051] At least a portion of the connecting portion COP can be bent, a first end (or first end portion) of the connecting portion COP can be disposed on a portion of the display panel DP, and a second end (or second end portion) of the connecting portion COP can be disposed on a portion of the circuit board portion CBP. The connecting portion COP may have a flip-chip structure, but this disclosure is not limited thereto. As the connecting portion COP bends, the circuit board portion CBP can be provided on the rear surface of the display panel DP.

[0052] The circuit board section CBP can supply electrical signals (data, driver signals, etc.) for controlling the operation of pixels in the display panel DP via the connection section COP. Pixels formed in the display panel DP can emit light based on the supplied electrical signals, etc.

[0053] In this embodiment, at least a portion of the circuit board portion CBP may be included in the processor PC (see [link]). Figure 1 In this case, the CBP portion of the circuit board may be set separately from the processor PC. However, this disclosure is not limited to any particular example.

[0054] The circuit board portion CBP can be connected to the end portion (or end portion) of the display panel DP via the connecting portion COP. After the display panel DP is attached to the cover window portion CV, the circuit board portion CBP can be positioned on the rear surface of the display panel DP as the connecting portion COP is bent.

[0055] The overlay window portion CV can be positioned on the display panel DP. Based on the display direction DR_D along which visual information is output from the display area DA, the overlay window portion CV can form the outer periphery (e.g., the outermost periphery) of the display component 100.

[0056] The cover window portion CV can be coupled (e.g., bonded) to the upper surface of the display panel DP. In an embodiment, a transparent adhesive layer (not shown) can be placed between the cover window portion CV and the display panel DP, which are coupled (e.g., bonded) to each other via the transparent adhesive layer. The transparent adhesive layer can include acrylic or epoxy materials. However, this disclosure is not limited thereto.

[0057] The cover window portion CV can form a space in which the display panel DP is disposed. The cover window portion CV may have an opening at the bottom, such that the display panel DP can be provided through the rear surface of the cover window portion CV. In embodiments, for example, the cover window portion CV may have an approximately flat dome shape with an opening at the bottom. However, this disclosure is not limited thereto.

[0058] The cover window portion CV may include at least a partially curved portion. The cover window portion CV may have a shape (e.g., a cross-sectional shape) that is at least partially curved. In embodiments, for example, the cover window portion CV may include a curved surface. The cover window portion CV may be curved inward in a direction opposite to the display direction DR_D (e.g., the direction facing the rear surface of the display panel DP). At least a portion of the outer surface of the cover window portion CV may form a convex surface.

[0059] The cover window portion CV may include a first portion PP and a second portion CP. The first portion PP has a relatively flat outer surface and is formed at and around the center of the display component 100. The second portion CP is formed on the outer periphery of the first portion PP and includes at least a partially curved area. The inner surface of the first portion PP may be coupled (e.g., joined) to the display panel DP. The second portion CP may form a side portion of the cover window portion CV. At least a portion of the second portion CP may extend in the thickness direction of the display panel DP. In embodiments, for example, the second portion CP may be integral with the first portion PP and may surround the entire edge of the first portion PP.

[0060] Reference Figures 6 to 11 The present section will describe a guide film GF that can be applied (e.g., used) during the process of coupling the display panel DP and the cover window portion CV. For ease of illustration, descriptions that may overlap with the foregoing description will be shown schematically or omitted.

[0061] Figures 6 to 11 This is a schematic diagram illustrating an embodiment of the guiding membrane GF.

[0062] Figures 6 to 8 This is a schematic plan view illustrating an embodiment of the guide film GF. Figure 6 The diagram schematically shows the guiding membrane GF to which the temporary covering portion TC is attached. Figure 7 and Figure 8 The guide membrane GF is schematically shown with the temporary covering portion TC removed from it. Figure 7 An embodiment in which the guiding membrane GF includes a cavity CAV is schematically illustrated, and Figure 8 An embodiment in which the guiding membrane GF does not include the cavity CAV is schematically shown.

[0063] Figures 9 to 11This is a schematic cross-sectional view illustrating an embodiment of the guide membrane GF. Figure 9 Show along Figure 6 The cross section intercepted by line B-B' and along Figure 7 The cross section intercepted by line C-C'. Figure 10 It is along Figure 6 The cross-sectional view taken by line D-D'. Figure 11 It is along Figure 6 A cross-sectional view of line E-E'.

[0064] Reference Figures 6 to 11 A guiding film GF is provided. The guiding film GF can be in film form and can form a display panel DP depending on whether the temporary covering portion TC is removed or attached (see reference). Figure 5 The area that can be coupled (e.g., joined).

[0065] The guiding membrane GF may include a membrane substrate FB, an adhesive layer ADS, and a temporary covering portion TC.

[0066] The membrane substrate FB can form a matrix guiding the membrane GF. The membrane substrate FB can extend in a first direction DR1. The membrane substrate FB can include a first end portion EP1 and a second end portion EP2, and the membrane substrate FB can be clamped by a clamping portion CLP (see reference) at each of the first end portion EP1 and the second end portion EP2. Figure 13 Clamping.

[0067] In this disclosure, the first direction DR1 can be the longitudinal direction of the guiding membrane GF (or the membrane substrate FB). The second direction DR2 can be the width direction of the guiding membrane GF (or the membrane substrate FB). The third direction DR3 can be the thickness direction of the guiding membrane GF (or the membrane substrate FB).

[0068] The membrane substrate FB can comprise a variety of materials. In embodiments, for example, the membrane substrate FB can comprise polymeric materials such as various plastics. In embodiments, for example, the membrane substrate FB can comprise polyethylene terephthalate (“PET”). However, this disclosure is not limited thereto.

[0069] The membrane substrate FB may include multiple layers. In an embodiment, for example, the membrane substrate FB may include a first membrane substrate FB1 and a second membrane substrate FB2 on the first membrane substrate FB1.

[0070] A portion of the second membrane substrate FB2 may not be disposed on the first membrane substrate FB1 and may define a membrane opening region FOP. The membrane opening region FOP may expose the first membrane substrate FB1. The membrane opening region FOP may define a space in which the adhesive layer ADS is disposed. In an embodiment, for example, the membrane opening region FOP may be defined in an intermediate portion MP, and the adhesive layer ADS may be provided within a panel placement area PL formed by the intermediate portion MP.

[0071] In an embodiment, the membrane substrate FB may include a central portion MP, a side portion SP forming a wing portion WP, and an opening region OPN.

[0072] The intermediate portion MP can be disposed between the first side portion SP1 and the second side portion SP2 based on the first direction DR1. The intermediate portion MP can form a panel placement area PL. The intermediate portion MP (or panel placement area PL) can have the same shape in a plan view as the display panel DP to be disposed on the guide film GF. In an embodiment, for example, the intermediate portion MP (or panel placement area PL) can have a circular shape.

[0073] The panel placement area PL formed by the intermediate portion MP can have an area greater than or equal to the area of ​​the lower surface of the display panel DP. In an embodiment, for example, an adhesive layer ADS can be disposed within the intermediate portion MP. Furthermore, when the panel placement area PL has an area greater than or equal to the area of ​​the display panel DP, the area where the adhesive layer ADS is disposed can also have an area greater than or equal to the area of ​​the display panel DP. The display panel DP can be tightly attached to the film substrate FB via the adhesive layer ADS, and process deviations in attaching the display panel DP to the guide film GF can be compensated, thereby improving process convenience.

[0074] In the embodiment ( Figure 6 and Figure 7 In this embodiment, the guide film GF may include a cavity CAV. The cavity CAV can be used as an alignment key for attaching the display panel DP to the guide film GF. In embodiments, for example, the cavity CAV may have a visually recognizable shape. The cavity CAV may be a groove structure defined in at least a portion of the intermediate portion MP.

[0075] A cavity CAV may include multiple cavities. In an embodiment, for example, a cavity CAV may include, in a plan view, a first cavity defined on the upper left (e.g., in the upper left portion of the middle portion MP), a second cavity defined on the lower left (e.g., in the lower left portion of the middle portion MP), a third cavity defined on the upper right (e.g., in the upper right portion of the middle portion MP), and a fourth cavity defined on the lower right (e.g., in the lower right portion of the middle portion MP). However, the number of cavity CAVs is not limited to the specific example.

[0076] To display panel DP (see Figure 4 ) and the CV of the overlay window (see Figure 4 The display panels (DP) are tightly coupled to each other, allowing for precise alignment on the middle portion (MP) of the guide film (GF). For example, if the display panels (DP) are not precisely aligned on the guide film (GF), they may be coupled (e.g., joined) to the cover window portion (CV) in an unintended arrangement. As a result, there may be a risk of reduced device reliability. For instance, durability may be compromised due to incomplete coupling between the display panels (DP) and the cover window portion (CV).

[0077] However, in an embodiment, the cavity CAV that enables precise alignment of the display panel DP can be formed in the guide film GF. The placement relationship between the guide film GF and the display panel DP can be clearly identified based on the position of the cavity CAV, and the display panel DP can be suitably aligned on the guide film GF.

[0078] However, this disclosure is not limited thereto. In the embodiments ( Figure 8 In, for example, the guiding membrane GF may not include the cavity CAV.

[0079] Side portions SP can be formed on opposite sides of the middle portion MP. Side portions SP can form a first end portion EP1 and a second end portion EP2. Side portions SP can extend in a first direction DR1.

[0080] The side portion SP may include a first side portion SP1 and a second side portion SP2. The first side portion SP1 may be adjacent to the first end portion EP1 and may be formed on one side of the middle portion MP. The second side portion SP2 may be adjacent to the second end portion EP2 and may be formed on the opposite side of the middle portion MP.

[0081] The side portion SP and the middle portion MP can define the opening region OPN. The opening region OPN can penetrate the membrane matrix FB (e.g., the first membrane matrix FB1 and the second membrane matrix FB2) in each of the multiple side portions of the side portion SP.

[0082] The opening region OPN may extend in the first direction DR1. In embodiments, the opening region OPN may also be referred to as a slit. The opening region OPN may have a polygonal shape. However, this disclosure is not limited thereto.

[0083] In an embodiment, the opening region OPN may have a width that narrows (decreases) toward the central portion MP (e.g., the panel placement region PL). When the display panel DP is provided in the panel placement region PL, the area supported by the central portion MP can be increased, allowing the display panel DP to be supported more reliably.

[0084] The opening region OPN may be adjacent to (e.g., directly adjacent to) the central portion MP. The opening region OPN may also be adjacent to (e.g., directly adjacent to) the panel placement area PL. In an embodiment, for example, a portion of the opening region OPN may be surrounded by the side portion SP, and another portion of the opening region OPN may be surrounded by the central portion MP. In an embodiment, for example, the opening region OPN may define a recessed groove structure within a portion of the central portion MP.

[0085] When the display panel DP is provided in the panel placement area PL, a portion of the display panel DP can overlap with the middle portion MP in the plan view, and another portion of the display panel DP can overlap with the opening area OPN in the plan view.

[0086] In this embodiment, when the display panel DP is provided on the guide film GF, the display panel DP can overlap with the opening region OPN while being supported by the intermediate portion MP. Therefore, the risk of process defects (e.g., appearance bubbles, etc.) can be reduced during the coupling process between the cover window portion CV, which has an inwardly curved shape, and the display panel DP.

[0087] The opening region OPN can be provided in multiple ways (e.g., provided as multiple opening regions OPN). In an embodiment, for example, the opening region OPN may include a first opening region OPN1 and a second opening region OPN2, the first opening region OPN1 being defined on one side of the intermediate portion MP between the first end portion EP1 and the panel placement area PL, and the second opening region OPN2 being defined on the opposite side of the intermediate portion MP between the second end portion EP2 and the panel placement area PL. In an embodiment, for example, the first opening region OPN1 may be defined in the first side portion SP1, and the second opening region OPN2 may be defined in the second side portion SP2.

[0088] In this embodiment, the first opening region OPN1 and the second opening region OPN2 can be symmetrical with respect to the central virtual line CL. The central virtual line CL can extend in the second direction DR2 and pass through the center of the intermediate portion MP. The guide film GF can more reliably support the display panel DP.

[0089] In an embodiment, the opening region OPN may include a plurality of opening regions OPN spaced apart in the second direction DR2. For example, in an embodiment, the first opening region OPN1 may include a (1-1)th opening region OPN1-1 and a (1-2)th opening region OPN1-2 spaced apart in the second direction DR2. The second opening region OPN2 may include a (2-1)th opening region OPN2-1 and a (2-2)th opening region OPN2-2 spaced apart in the second direction DR2.

[0090] In an embodiment, the (1-1) opening region OPN1-1 and the (1-2) opening region OPN1-2 may have different shapes from each other. However, this disclosure is not limited thereto, and the (1-1) opening region OPN1-1 and the (1-2) opening region OPN1-2 may have the same shape from each other.

[0091] In an embodiment, the (2-1) opening region OPN2-1 and the (2-2) opening region OPN2-2 may have different shapes from each other. However, this disclosure is not limited thereto, and the (2-1) opening region OPN2-1 and the (2-2) opening region OPN2-2 may have the same shape from each other.

[0092] The side portion SP can form the wing portion WP. The wing portion WP can be formed on opposite sides of the middle portion MP, and the wing portion WP can support the middle portion MP on opposite sides of the middle portion MP. The wing portion WP can be directly adjacent to each of the opposite sides of the middle portion MP.

[0093] The wing portion WP may include a first wing portion WP1 and a second wing portion WP2. The first wing portion WP1 may be adjacent to the first end portion EP1 and may be formed on one side of the middle portion MP. The second wing portion WP2 may be adjacent to the second end portion EP2 and may be formed on the opposite side of the middle portion MP.

[0094] In an embodiment, the wing portion WP can be formed by multiple opening regions OPN. For example, in an embodiment, the first wing portion WP1 can be provided by two opening regions OPN1-1 and OPN1-2 spaced apart in the second direction DR2. The second wing portion WP2 can be provided by two opening regions OPN2-1 and OPN2-2 spaced apart in the second direction DR2.

[0095] In an embodiment, the middle portion MP may have a smaller width along the second direction DR2 than the side portion SP. The middle portion MP may have a first width W1 along the second direction DR2, and the side portion SP may have a second width W2 along the second direction DR2 that is larger than the first width W1. When the display panel DP is disposed within the panel placement area PL, the display panel DP may not extend beyond the outer periphery of the guide film GF in the width direction based on the guide film GF, or the possibility that a portion of the display panel DP may be improperly pushed by the guide film GF may be reduced.

[0096] The adhesive layer ADS can be disposed within the intermediate portion MP. In an embodiment, for example, the adhesive layer ADS can be disposed within the panel placement area PL. The adhesive layer ADS can be disposed on the first film substrate FB1. The adhesive layer ADS can be disposed within the film opening area FOP defined by the second film substrate FB2.

[0097] When the display panel DP is provided on the guide film GF, the adhesive layer ADS can fix the position of the display panel DP on the guide film GF. Depending on whether the temporary cover portion TC is removed, the adhesive layer ADS may be exposed to the outside or may not be exposed to the outside. The adhesive layer ADS can include various resin materials containing adhesive materials, and embodiments of the adhesive materials are not limited to any particular example.

[0098] The temporary cover portion TC can removably cover the adhesive layer ADS. The temporary cover portion TC can cover the adhesive layer ADS, and the temporary cover portion TC can be removed from the adhesive layer ADS to allow the display panel DP to be positioned on the adhesive layer ADS. Before the display panel DP is positioned within the panel placement area PL, the temporary cover portion TC may not expose the adhesive layer ADS.

[0099] The temporary cover portion TC may include the handle portion HP and the adhesive cover portion AC.

[0100] When the temporary cover portion TC covers the adhesive layer ADS, the handle portion HP can extend outward from the middle portion MP, and external force can be provided by the handle portion HP to separate the temporary cover portion TC from the adhesive layer ADS.

[0101] The adhesive cover portion AC is connected to the handle portion HP and can cover (e.g., completely cover) the adhesive layer ADS. The adhesive cover portion AC can have the same shape as the middle portion MP (or panel placement area PL), and the adhesive cover portion AC can have a similar area to the middle portion MP (or panel placement area PL).

[0102] In an embodiment, when the temporary cover portion TC covers the adhesive layer ADS, at least a portion of the temporary cover portion TC (or the adhesive cover portion AC) may overlap with the opening region OPN in a plan view.

[0103] Reference Figures 12 to 21 The description will cover the fabrication of electronic devices ED using the guide film GF in the embodiments (see [link]). Figure 1 The method is described below. For simplicity, descriptions that may overlap with the foregoing will be shown or omitted. Furthermore, for ease of explanation, the method will be based on the manufacture of watchmaking device 1 (see...). Figure 2 The method describes the manufacturing method of electronic devices (ED).

[0104] Figure 12 This is a schematic flowchart illustrating an embodiment of a method for manufacturing an electronic device ED (e.g., watch device 1) using a guide film GF. Figures 13 to 21 This is a schematic diagram illustrating various operations of a method for manufacturing an electronic device ED (e.g., watch device 1) using a guide film GF. In the embodiments, the process method including operations S200, S400, S600, S800, and S900, which will be described below, can also be referred to as a method for coupling a display panel DP and a cover window portion CV.

[0105] For ease of explanation, Figure 13 , Figure 15 and Figure 17 Schematic illustration based on such Figure 6 and Figure 7 The process operation of the planar structure of the guide film GF shown is illustrated. For ease of explanation, Figure 14 , Figure 16 , Figure 18 , Figure 20 and Figure 21 Schematic illustration based on such Figure 9 The process operation of the cross-sectional structure of the guide membrane GF shown in the figure. Figure 19 It is along Figure 17 A schematic cross-sectional view of the line F-F'.

[0106] Reference Figure 12The method of manufacturing an electronic device ED (e.g., watch device 1) using the guide film GF in the embodiments may include: the process of providing the guide film in operation S200; the process of removing the temporary covering portion in operation S400; the process of setting the display panel on the guide film in operation S600; the process of coupling the covering window portion and the display panel in operation S800; and the process of separating the display panel from the guide film in operation S900.

[0107] Reference Figures 12 to 14 In operation S200, which provides the guide membrane, the guide membrane GF can be prepared.

[0108] In operation S200, the temporary cover portion TC can cover the adhesive layer ADS, and the top surface of the adhesive layer ADS can be left unexposed.

[0109] In operation S200, the clamping portion CLP can secure the first end portion EP1 and the second end portion EP2 of the guide film GF. The position of the guide film GF can be fixed by the clamping portion CLP.

[0110] Reference Figure 12 , Figure 15 and Figure 16 In operation S400, the temporary covering portion TC can be removed, and the outer surface of the adhesive layer ADS can be exposed.

[0111] In operation S400, when the position of the guide film GF is fixed by the clamping portion CLP, the temporary covering portion TC can be spaced apart from the adhesive layer ADS (e.g., separated). In an embodiment, the adhesive covering portion AC can be effectively removed from the adhesive layer ADS using the handle portion HP.

[0112] Therefore, in operation S400, the guide film GF can be prepared in a state where the display panel DP can be attached to the guide film GF. In an embodiment, for example, in operation S400, the surface of the adhesive layer ADS in the panel placement area PL can be exposed.

[0113] Reference Figure 12 , Figure 17 , Figure 18 and Figure 19 In operation S600, where the display panel is set on the guide film, the display panel DP can be set on the adhesive layer ADS.

[0114] In operation S600, the display panel DP can be positioned on the middle portion MP. The display panel DP can also be positioned on the adhesive layer ADS within the panel placement area PL. The display panel DP can be fixed at a fixed position on the guide film GF via the adhesive layer ADS.

[0115] In operation of S600, the position of the guide film GF can be precisely determined by the cavity CAV, and based on the determined position of the guide film GF, the display panel DP can be aligned to the expected position and orientation within the panel placement area PL.

[0116] In operation S600, the display panel DP can be coupled (e.g., bonded) to the circuit board portion CBP via the connecting portion COP. The connecting portion COP can be disposed on a surface of a portion of the display panel DP, and the lower surface of the display panel DP can be attached to the adhesive layer ADS. The connecting portion COP can be formed on a side different from the side of the handle portion HP on which the temporary cover portion TC is disposed.

[0117] In operation S600, the display panel DP can overlap with the opening region OPN in a plan view (e.g., along the third direction DR3), and the display panel DP can be supported by the intermediate portion MP. Therefore, a portion of the lower surface of the display panel DP can be supported by the guide film GF, and another portion of the lower surface of the display panel DP can be opened by the opening region OPN.

[0118] In operation S600, the display panel DP can be positioned at a fixed location relative to the guide film GF, and the end portion of the display panel DP may not protrude (or extend) beyond the first virtual line VL1 and the second virtual line VL2. The end portion of the display panel DP may be formed inside the first virtual line VL1 and the second virtual line VL2. This reduces the risk of a portion of the display panel DP being improperly pushed by the guide film GF and reduces the risk of a portion of the display panel DP being improperly coupled (e.g., bonded) to the cover window portion CV in subsequent processes.

[0119] The first virtual line VL1 and the second virtual line VL2 can be defined along the side surfaces of the first side portion SP1 and the second side portion SP2 extending in the first direction DR1.

[0120] When the display panel DP is positioned in the panel placement area PL during operation S600, a portion of the panel placement area PL may not be covered by the display panel DP, and the separation area EA, which is a portion of the panel placement area PL, may be exposed. In an embodiment, the panel placement area PL may have an area greater than or equal to the area of ​​the display panel DP, thereby allowing the display panel DP to be sufficiently attached to the adhesive layer ADS with high reliability.

[0121] Reference Figure 12 and Figure 20In the operation S800 of coupling the cover window portion and the display panel, the cover window portion CV and the display panel DP can be close to each other (adjacent) and can be coupled to each other (e.g., joined).

[0122] In operation S800, when the lower portion of the display panel DP is supported by the guide film GF, the cover window portion CV and the display panel DP can be moved to be close to each other (adjacent). Therefore, the display panel DP can be pushed onto the third-direction DR3, such that the cover window portion CV and the display panel DP can be coupled (e.g., bonded) to each other. In an embodiment, for example as described above, a transparent adhesive layer may be placed between the cover window portion CV and the display panel DP.

[0123] In an embodiment, the display panel DP, which is fixed by a guide film GF including an opening region OPN, can be suitably coupled (e.g., bonded) to a cover window portion CV having a curved structure.

[0124] In experiments, when the display panel DP is provided within the curved area of ​​the cover window portion CV, due to the curved area of ​​the inner surface of the cover window portion CV, there is a possibility that a part of the display panel DP may be unsuitably attached to the cover window portion CV.

[0125] However, in this embodiment, the guide film GF can push the display panel DP with a portion of its lower surface open through the opening region OPN, thus preventing interference around the periphery of the end portion of the display panel DP caused by the bending of the cover window portion CV. Therefore, coupling between the display panel DP and the cover window portion CV can be suitably achieved. Furthermore, the risk of air bubbles or the like being generated between the display panel DP and the cover window portion CV can be reduced, thereby improving the display component 100 (see [link]). Figure 2 The display quality and reliability of the device.

[0126] Furthermore, since the display panel DP and the cover window portion CV can be suitably coupled (e.g., bonded) through the opening area OPN of the guide film GF, and the lower surface of the display panel DP can be supported by the middle portion MP forming the panel placement area PL, the placement stability of the display panel DP during the manufacturing process can be improved. As a result, process efficiency can be improved because the risk of the display panel DP not being aligned to the expected position and orientation can be reduced during the process.

[0127] Reference Figure 12 and Figure 21 In the operation S900 of separating the display panel from the guide film, the guide film GF can be separated from the display panel DP while the cover window portion CV and the display panel DP are coupled (e.g., joined) to each other.

[0128] In operation S900, the adhesive layer ADS can be separated from the display panel DP, and a coupling structure can be formed between the display panel DP and the cover window portion CV.

[0129] Subsequently, in an embodiment, the circuit board portion CBP can be coupled (e.g., bonded) to the rear surface of the display panel DP, and the lower substrate LB (see Figure 4 The display panel DP can be disposed on the lower portion of the display panel DP. The display panel DP can form the display component 100, enabling the provision of the electronic device ED in the embodiments. In the embodiments, the display component 100 can be coupled (e.g., joined) to the watchband component 200 (see...). Figure 3 As a result, the watch device 1 in the embodiments can be provided.

[0130] Through embodiments of this disclosure, a guide film, a method for manufacturing an electronic device using the guide film, and an electronic device manufactured by the method of manufacturing an electronic device can be provided, wherein a display panel and a cover window included in the electronic device can be tightly coupled (e.g., joined) to each other.

[0131] In embodiments of this disclosure, a guide film, a method for manufacturing an electronic device using the guide film, and an electronic device manufactured by the method for manufacturing an electronic device can be provided, wherein the convenience of the process for coupling the display panel and the cover window can be improved, and the reliability of the process can be improved by precisely aligning the display panel.

[0132] This disclosure should not be construed as limiting itself to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure thorough and complete, and to fully convey the concept of this disclosure to those skilled in the art.

[0133] Although this disclosure has been specifically shown and described with reference to embodiments thereof, those skilled in the art will understand that various changes in form and detail may be made in the embodiments without departing from the spirit or scope of this disclosure as defined by the appended claims.
