[0026] Advantages and features of the present disclosure and methods for achieving the same will be clarified through exemplary embodiments described below with reference to the accompanying drawings.

[0027] The present disclosure will now be described more fully below with reference to the accompanying drawings, in which various embodiments are shown. However, the present disclosure may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. The same reference numerals represent the same elements throughout.

[0028] It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0029] It will be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers 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, without departing from the teachings herein, the "first element", "first component", "first region", "first layer" or "first part" discussed below may be referred to as a second element, second component, second region, second layer or second part.

[0030] The terms used herein are only used for the purpose of describing specific embodiments and are not intended to be limited. As used herein, "one", "the", "at least one" do not represent the limitation of quantity, and are intended to include both the singular and the plural, unless the context clearly indicates otherwise. For example, "an element" has the same meaning as "at least one element", unless the context clearly indicates otherwise. "At least one" should not be interpreted as limiting "one" or "one". "Or" means "and / or". As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items. It will be further understood that when used in this specification, the term "comprises" and / or "comprising" or "includes" and / or "including" specifies the existence of stated features, regions, wholes, steps, operations, elements and / or components, but does not exclude the existence or addition of one or more other features, regions, wholes, steps, operations, elements, components and / or groups thereof.

[0031] 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 drawings. It will be understood that relative terms are intended to include different orientations of the device in addition to the orientation depicted in the drawings. For example, if the device in one of the drawings is turned over, the element described as being on the "lower" side of the other elements will then be oriented on the "upper" side of the other elements. Therefore, depending on the specific orientation of the drawings, the term "lower" may include both "lower" and "upper" orientations. Similarly, if the device in one of the drawings is turned over, the element described as being "below" or "below" the other elements will then be oriented to be "above" the other elements. Therefore, the term "below" or "below" may include both upper and lower orientations.

[0032] As used herein, "about" or "approximately" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, in view of the measurements in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0033] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure 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 art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0034] Embodiments are described herein with reference to cross-sectional views as schematic diagrams of idealized embodiments. As such, variations in the shapes in the figures, such as due to manufacturing techniques and / or tolerances, should be expected. Therefore, the embodiments described herein should not be interpreted as being limited to the specific shapes of the regions as shown herein, but should include deviations in shapes, such as those caused by manufacturing. For example, a region shown or described as flat may typically have rough and / or nonlinear features. In addition, the sharp corners shown may be rounded. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the regions, and are not intended to limit the scope of the claims.

[0035] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0036] Figure 1 is a perspective view of a bonding device according to one or more embodiments of the present disclosure. Figure 2 yes Figure 1 A perspective view of an embodiment of a cover. Figure 3 yes Figure 1 A stereogram of an embodiment of an alignment camera.

[0038] The coupling part IMP may include a controller MDP, a plurality of motors SUM, and a cover CV. The motor SUM may be disposed on the controller MDP. The cover CV and the controller MDP may be arranged in a first direction DR1. One of the opposite sides of the controller MDP in the first direction DR1 may be in contact with the cover CV. One of the opposite sides of each of the motors SUM in the first direction DR1 may be in contact with the cover CV. One side of each of the controller MDP and the motor SUM may be defined as a side facing the alignment camera ACM.

[0039] The controller MDP may include an upper controller TP, a middle controller MP, and a lower controller BP. The lower controller BP, the middle controller MP, and the upper controller TP may be stacked in sequence.

[0040] The upper controller TP may have a rectangular parallelepiped shape. When viewed in a plan view, the top surface of the upper controller TP may have a rectangular shape having a shorter side extending in a first direction DR1 and a longer side extending in a second direction DR2. However, the embodiments of the present disclosure are not limited thereto, and the upper controller TP may have various other shapes (e.g., a circular shape, other polygonal shapes). It should be understood that when describing in detail the shape of an object (e.g., the "longer side" and the "shorter side" of an object), the terms "longer" and "shorter" are relative terms indicating the size of the object.

[0041] In the example description herein, a direction substantially perpendicularly crossing a plane defined by the first direction DR1 and the second direction DR2 is defined as a third direction DR3. In this specification, the term "viewed from a plane" may refer to a state of viewing in the third direction DR3.

The center of each of the longer sides of the intermediate controller MP and the center of each of the longer sides of the upper controller TP may match each other (e.g., along an axis parallel to the second direction DR2). In some examples, the length of each of the longer sides of the intermediate controller MP may be less than the length of each of the longer sides of the upper controller TP.

[0044] The lower controller BP may be disposed below the middle controller MP. When viewed in the second direction DR2, the lower controller BP may have a rectangular shape having longer sides extending in the first direction DR1 and shorter sides extending in the third direction DR3. The center of each of the longer sides of the lower controller BP may match the center of each of the longer sides of the middle controller MP (e.g., along the second direction DR2). The center of each of the longer sides of the lower controller BP may match the center of each of the longer sides of the upper controller TP (e.g., along the second direction DR2). For example, the length of each of the longer sides of the lower controller BP may be greater than the length of each of the longer sides of the middle controller MP.

[0045] Two surfaces of the upper controller TP that are opposite to each other in the second direction DR2 may be arranged on the same plane as two surfaces of the middle controller MP that are opposite to each other in the second direction DR2. Two surfaces of the lower controller BP that are opposite to each other in the second direction DR2 may be arranged on the same plane as two surfaces of the middle controller MP that are opposite to each other in the second direction DR2.

[0046] Although not shown, the middle controller MP can move in at least one of the first direction DR1, the second direction DR2, and the third direction DR3 along the top surface of the lower controller BP. When the middle controller MP moves, the upper controller TP connected to the middle controller MP may move in the same direction as the moving direction of the middle controller MP. Fig.11D , Fig.11F and Fig.11G The movement of the middle controller MP and the upper controller TP is described in detail.

[0047] refer to Figure 1 and Figure 2 , the cover CV may include a first cover CV1 and a second cover CV2. The first cover CV1 may have a rectangular parallelepiped shape. When viewed in the first direction DR1, the first cover CV1 may have a rectangular shape having a longer side extending in the second direction DR2 and a shorter side extending in the third direction DR3.

[0048] The second cover CV2 may be disposed on the first cover CV1. The second cover CV2 may have a rectangular parallelepiped shape. When viewed in the first direction DR1, the second cover CV2 may have a rectangular shape having longer sides extending in the second direction DR2 and shorter sides extending in the third direction DR3.

[0049] When viewed in the first direction DR1, the center of the longer side of the first cover CV1 may match the center of the longer side of the second cover CV2. When viewed in the first direction DR1, the length of the second cover CV2 in the second direction DR2 may be greater than the length of the first cover CV1 in the second direction DR2. When viewed in the first direction DR1, the length of the second cover CV2 in the third direction DR3 may be less than the length of the first cover CV1 in the third direction DR3.

[0050] The first groove GR1 may be defined in the top surface of the second cover CV2. The first groove GR1 may extend in the second direction DR2. The first groove GR1 may have a rectangular shape when viewed in a plan view.

[0051] The second groove GR2 may be defined in one of the opposite sides of the second cover CV2 in the first direction DR1. One surface of the second cover CV2 may be defined as a surface facing the alignment camera ACM. When viewed in the first direction DR1, the second groove GR2 may have a rectangular shape having a longer side extending in the second direction DR2 and a shorter side extending in the third direction DR3. In essence, the first groove GR1 and the second groove GR2 may be defined as being integral with each other.

[0052] refer to Figure 1 , a plurality of motors SUM may be disposed on the controller MDP. The motor SUM may be disposed on the top surface of the upper controller TP. The motor SUM and the upper controller TP may be connected to each other.

[0053] According to one or more embodiments of the present disclosure, although two motors SUM are illustrated, the number of motors SUM is not limited thereto, and one motor SUM or more than two motors SUM may be provided on the controller MDP.

[0054] When viewed in the second direction DR2 , each of side surfaces of the motor SUM that are opposite to each other in the second direction DR2 may have a rectangular shape.

[0055] The motor SUM may convert the suction holes SH defined in the suction portion SPT into a vacuum state. Aspects of the suction portion SPT are described later herein. Fig.11A Converting the adsorption holes SH to the vacuum state is described in detail.

[0056] Each of the plurality of panel fixing parts LDP may be disposed on a corresponding motor SUM of the motor SUM. Each of the panel fixing parts LDP may be disposed on the cover CV.

[0057] The panel fixing parts LDP may be spaced apart from each other in the second direction DR2. Figure 1, two panel fixing portions LDP are shown, but the embodiments of the present disclosure are not limited thereto, and one or more panel fixing portions LDP may be provided on the corresponding motor SUM. Fig.13 and Fig.14 The number of panel fixing parts LDP is described in detail.

[0058] The panel fixing part LDP may include a first stage STG1, a support part SPP, a first plate part FR1, and a second plate part FR2. For example, each panel fixing part LDP may include a first stage STG1, a support part SPP, a first plate part FR1, and a second plate part FR2.

[0059] The support portion SPP may be disposed on the top surface of the second cover CV2. The support portion SPP may overlap with the first groove GR1. Although not shown, one or more grooves may be defined in the top surface of the support portion SPP. The groove defined in the top surface of the support portion SPP may overlap with the first groove GR1 defined in the top surface of the second cover CV2.

[0060] Each first plate portion FR1 may be disposed on a corresponding support portion SPP. The first plate portion FR1 may overlap the second groove GR2. For example, when viewed in the first direction DR1, each of the first plate portions FR1 may have a rectangular shape. However, the shape of the first plate portion FR1 is not limited thereto, and each of the first plate portions FR1 may have various shapes.

[0061] Each of the first plate portions FR1 may include quartz. The first plate portion FR1 may be transparent. In some aspects, light emitted from an alignment camera ACM to be described later herein may pass through the first plate portion FR1.

[0062] Each of the second plate portions FR2 may be disposed on a corresponding one of the motors SUM. Each of the first plate portions FR1 may be arranged with the corresponding second plate portion FR2 in the first direction DR1.

[0063] The second plate portion FR2 may be connected to a motor SUM. In an example, the second plate portion FR2 may be connected to the controller MDP through the motor SUM. Therefore, when the upper controller TP and the middle controller MP move, the second plate portion FR2 may move in the same direction as the movement direction of the upper controller TP and the middle controller MP. FIG. 11D to FIG. 11G The movement of the second plate portion FR2 is described in detail.

[0064] Each of the first stages STG1 may be disposed on the corresponding first plate portion FR1 and the corresponding second plate portion FR2. Each of the first stages STG1 may overlap the corresponding first plate portion FR1 and the second plate portion FR2.

[0065] Each of the first stages STG1 may have a plane defined by the first direction DR1 and the second direction DR2. For example, when viewed in a plan view, each of the first stages STG1 may have a rectangular shape having a longer side extending in the first direction DR1 and a shorter side extending in the second direction DR2. However, the embodiments of the present disclosure are not limited thereto, and each of the first stages STG1 may have a rectangular shape having a shorter side extending in the first direction DR1 and a longer side extending in the second direction DR2. Fig.13 and Fig.14 The shape of the first STG1 is described in detail.

[0066] Reference Fig. 7A and Figure 7B The display panel DP and the data driver DC ( Figure 1 (not shown) can be set on the first STG1. FIG. 11A to FIG. 11I An exemplary aspect in which the display panel DP and the data driver DC are provided on the first stage STG1 is described in detail.

The adsorption portion SPT and the transmission portion TRT may be arranged in the first direction DR1. Substantially, each adsorption portion SPT may be integrated with the corresponding transmission portion TRT.

[0068] In the example, the adsorption portion SPT may be disposed on the second flat plate portion FR2. The adsorption portion SPT may overlap the motor SUM. The adsorption portion SPT may be connected to the motor SUM through the second flat plate portion FR2. Therefore, when the upper controller TP and the middle controller MP move, the first stage STG1 may move in the same direction as the moving direction of the upper controller TP and the middle controller MP.

[0069] A plurality of suction holes SH may be defined in the top surface of the suction portion SPT. The suction holes SH may be arranged in the first direction DR1 and the second direction DR2.

[0070] When viewed in a plan view, the suction hole SH may overlap with the motor SUM. When viewed in a plan view, the suction hole SH may not overlap with the first flat plate portion FR1. Although not shown, the suction hole SH may be connected to the motor SUM and converted into a vacuum state.

[0071] Each of the transmissive portions TRT may extend in the first direction DR1 to overlap the corresponding first plate portion FR1. When viewed in a plan view, the transmissive portion TRT may overlap the corresponding first plate portion FR1 and the first groove GR1.

[0079] According to one or more embodiments of the present disclosure, although not shown, gears may be provided in the first left-right adjustment portion YSP1, and gears may be provided at opposite sides of the second left-right adjustment portion YSP2 in the second direction DR2. The gears provided at both sides of the second left-right adjustment portion YSP2 may engage with the gears provided in the first left-right adjustment portion YSP1, and the rotation of the engaged gears may support the rotational movement. Therefore, when the second left-right adjustment portion YSP2 rotates about a rotation axis parallel to the second direction DR2, the first left-right adjustment portion YSP1 may move in the second direction DR2.

[0080] The third left-right adjusting portion YSP3 may be connected to the second left-right adjusting portion YSP2. Although not shown, the second left-right adjusting portion YSP2 may be disposed in an opening defined by the third left-right adjusting portion YSP3. The second left-right adjusting portion YSP2 may pass through the opening of the third left-right adjusting portion YSP3.

[0081] The third left-right adjustment portion YSP3 can rotate around a rotation axis parallel to the second direction DR2. When the third left-right adjustment portion YSP3 rotates, the second left-right adjustment portion YSP2 connected to the third left-right adjustment portion YSP3 can rotate around a rotation axis parallel to the second direction DR2. When the second left-right adjustment portion YSP2 rotates, each of the first left-right adjustment portions YSP1 can move to the left or right (for example, the first left-right adjustment portion YSP1 can move in a direction opposite to the second direction DR2). For example, the first left-right adjustment portions YSP1 can move so that the distance between the first left-right adjustment portions YSP1 in the second direction DR2 increases or decreases.

[0082] The body portions BDP may be disposed on top surfaces of the first left-right adjusting portions YSP1. The body portions BDP may be spaced apart from each other in the second direction DR2. Each of the body portions BDP may be disposed on a corresponding first left-right adjusting portion YSP1 of the first left-right adjusting portions YSP1.

[0083] The body portion BDP may extend in the first direction DR1 and the third direction DR3. When viewed in the second direction DR2, each of the body portions BDP may have an "L" shape that is symmetrical to the left and right (e.g., the size of the body portion BDP in the first direction DR1 may be equal to the size of the body portion BDP in the third direction DR3).

[0084] Each front-rear adjustment portion XCP may be disposed on the corresponding first left-right adjustment portion YSP1. The front-rear adjustment portion XCP may be disposed adjacent to the other of the opposite sides of the first left-right adjustment portion YSP1 that are opposite to each other in the second direction DR2.

Each of the first front-to-back adjustment portions XSP1 may be disposed adjacent to one side of each of the body portions BDP (e.g., one side of the corresponding body portion BDP). Each of the first front-to-back adjustment portions XSP1 may be connected to one side of each of the body portions BDP (e.g., one side of the corresponding body portion BDP). One side of the body portion BDP may be defined as a side opposite to the other side facing each other.

[0087] The second front-to-back adjustment portion XSP2 may be disposed at a first side surface of the first left-to-right adjustment portion YSP1, wherein the first side surface is opposite to the second side surface of the first left-to-right adjustment portion YSP1 in the first direction DR1. The first side surface of the first left-to-right adjustment portion YSP1 may be defined as a side surface opposite to the second side surface adjacent to the body portion BDP. The second front-to-back adjustment portion XSP2 may be disposed adjacent to the other side of the first left-to-right adjustment portion YSP1 when viewed in the first direction DR1.

[0088] The shaft grooves SFG may be defined in the top surface of the second front-rear adjustment portion XSP2. Each of the shaft grooves SFG may have a partial circular shape (eg, a semicircular shape) when viewed in the first direction DR1.

[0089] The third front-rear adjustment portions XSP3 may be disposed in the shaft grooves SFG, respectively. The third front-rear adjustment portions XSP3 may be disposed between the first front-rear adjustment portions XSP1 and the second front-rear adjustment portions XSP2.

[0090] Each of the third front-rear adjustment portions XSP3 may have a cylindrical shape extending in the first direction DR1. One of the opposite sides of the third front-rear adjustment portion XSP3 in the first direction DR1 may be connected to the first front-rear adjustment portion XSP1. In other words, for a given third front-rear adjustment portion XSP3 having opposite end portions in the first direction DR1, one of the opposite end portions may be connected to the corresponding first front-rear adjustment portion XSP1.

[0091] Although not shown, a gear may be provided in each of the first front-rear adjustment parts XSP1. Although not shown, each of the third front-rear adjustment parts XSP3 may include a gear provided at one side (e.g., an opposite end portion). When the third front-rear adjustment part XSP3 rotates about a rotation axis parallel to the first direction DR1, the gears of the corresponding first front-rear adjustment part XSP1 and the gears of the third front-rear adjustment part XSP3 may engage with each other to rotate. The rotation of the engaging gears may cause the first front-rear adjustment part XSP1 to reciprocate in the first direction DR1.

One of the opposite sides on the first direction DR1 of the third front-to-back adjustment portion XSP3 can be defined as a side adjacent to the main body portion BDP. In other words, one of the opposite end portions on the first direction DR1 of the third front-to-back adjustment portion XSP3 (for example, one of the end portions connected to the corresponding first front-to-back adjustment portion XSP1) can be defined as an end portion adjacent to the main body portion BDP.

[0093] The fourth front-to-back adjustment portion XSP4 may be connected to the other side (also referred to herein as the end portion) of the third front-to-back adjustment portion XSP3. The fourth front-to-back adjustment portion XSP4 may be disposed at one of the opposite sides on the first direction DR1 of the second front-to-back adjustment portion XSP2. In other words, a set of surfaces of the second front-to-back adjustment portion XSP2 may face each other along an axis parallel to the first direction DR1, and the corresponding fourth front-to-back adjustment portion XSP4 may be disposed on one of the opposite facing surfaces.

The rotation of the engaged gears can cause the reciprocating motion of the first front-to-back adjustment part XSP1 in the first direction DR1. The main body part BDP can be closer to or farther away from the cover CV. In the example, in response to the rotation of the engaged gears, the main body part BDP associated with the third front-to-back adjustment part XSP3 and the first front-to-back adjustment part XSP1 can move so that the distance between the main body part BDP and the cover CV increases or decreases.

[0180] In some examples, Fig. 9 The data driver DC may be removed from the display panel DP.

[0181] For example, Fig.10 is an enlarged plan view of a portion of the data driver DC and the display panel DP.

[0182] For example, in Fig. 9 , the circuit board PB is omitted.

[0184] refer to Figure 7B and Fig. 9 , the data driver DC may be disposed on the first pad PD1 and the second pad PD2. The data driver DC may include a top surface DC-US and a bottom surface DC-DS. The bottom surface DC-DS of the data driver DC may be a surface facing the first pad PD1 and the second pad PD2.

[0185] The data driver DC may include a protruding electrode DC-BP electrically connected to a first pad PD1 disposed on a substrate SUB. The data driver DC may include a protruding electrode DC-BP electrically connected to a second pad PD2 disposed on the substrate SUB. The protruding electrode DC-BP may include a first protrusion BP1 and a second protrusion BP2. The first protrusion BP1 and the second protrusion BP2 may be spaced apart from each other in a first direction DR1. The first protrusion BP1 may be arranged in a second direction DR2. The second protrusion BP2 may be arranged in the second direction DR2. Although not shown, the first protrusion BP1 and the second protrusion BP2 may protrude from a bottom surface DC-DS of the data driver DC and be exposed to the outside.

[0186] The data driver DC may include a plurality of second marks MK2. Fig. 9 Two second marks MK2 are shown in FIG. 1 , but the number of second marks MK2 is not limited thereto.

[0187] The second marks MK2 may be spaced apart from each other in the second direction DR2. The second marks MK2 may be disposed on both sides of the data driver DC that are opposite to each other in the second direction DR2. In other words, the second marks MK2 may be disposed at opposite sides of the data driver DC, respectively.

[0188] For example, the second mark MK2 may be disposed adjacent to one of the opposite sides of the data driver DC in the first direction DR1. One side of the data driver DC may be defined as a side facing the circuit board PB. In other words, the side of the data driver DC on which the second mark MK2 is disposed may be defined as a side facing the circuit board PB.

[0189] In some examples, each of the second marks MK2 may have a cross shape. However, the embodiments of the present disclosure are not limited thereto, and the shape of the second marks MK2 may vary.

[0190] Although not shown, the data driver DC may include an integrated circuit. The integrated circuit may be disposed on the protruding electrode DC-BP. The integrated circuit may be connected to the protruding electrode DC-BP. The data driver DC may receive a first signal from the outside through the second pad PD2 and the second protrusion BP2. The data driver DC may provide a second signal generated based on the first signal to the first pad PD1 through the first protrusion BP1. The first signal may be an image signal applied from the outside as a digital signal, and the second signal may be a data signal as an analog signal. The data driver DC may generate an analog voltage corresponding to a grayscale value of the image signal. The data signal may be Fig. 7A and Figure 7B The data lines DL shown in FIG. 1 are provided to the pixels PX.

[0191] refer to Fig. 9 and Fig.10 , the data driver DC may be adhered to the first pad area PA1 by the first adhesive layer CF1. Although not shown, the circuit board PB may be adhered to the second pad area PA2 by an adhesive layer of the same type as the first adhesive layer CF1. The first adhesive layer CF1 may include an adhesive synthetic resin.

[0192] Aspects of the present disclosure support aligning the data driver DC with the first adhesive layer CF1 and the first pad area PA1 in association with disposing the first adhesive layer CF1 on the first pad area PA1. For example, when the first adhesive layer CF1 is disposed on the first pad area PA1, the data driver DC can be aligned. Specifically, the center of the first mark MK1 can be aligned to match the center of the second mark MK2. Fig.11D , Fig.11F and Fig.11G The alignment of the data driver DC is described in detail.

[0193] According to one or more embodiments of the present disclosure, after aligning the data driver DC with the first adhesive layer CF1, the technology described herein includes moving the data driver DC in the third direction DR3 so that the data driver DC contacts the top surface of the first adhesive layer CF1. The data driver DC may be connected to the display panel DP through the first adhesive layer CF1. Specifically, the first bump BP1 may contact and be electrically connected to the first pad PD1, and the second bump BP2 may contact and be electrically connected to the second pad PD2.

[0194] When the first bump BP1 and the second bump BP2 are connected to the first pad PD1 and the second pad PD2, the technology described herein also includes aligning the data driver DC with the first pad area PA1 (for example, using the first mark MK1 and the second mark MK2) to compensate for errors in the process. Specifically, when the data driver DC moves in the third direction DR3, errors may occur in the process. To this end, the technology described herein includes aligning the center between the first marks MK1 and the center between the second marks MK2 in the first direction DR1. Referring to FIG. 11E to FIG. 11F The alignment after moving the data driver DC is described in detail.

[0195] After aligning the data driver DC with the first adhesive layer CF1 (e.g., within a target tolerance), the techniques described herein include curing the first adhesive layer CF1. When the first adhesive layer CF1 is cured, the first and second pads PD1 and PD2 and the protruding electrode DC-BP may be fixed to contact each other. Fig.10As shown in , the technology described herein supports accurate mounting and connection of the data driver DC to the first pad area PA1 of the display panel DP by aligning the first mark MK1 and the second mark MK2.

[0196] FIG. 11A to FIG. 11I It is used to explain the use Figure 1 A view of a bonding method of an embodiment of a bonding device.

[0197] For example, FIG. 11A to FIG. 11D , Fig.11F and Fig.11I It is along Figure 1 A cross-sectional view taken along line II'.

[0198] Fig.11G The spectrum part PLP, the first stage STG1, the display panel DP, the first adhesive layer CF1, the data driver DC, and the pressing part PSP when viewed in the first direction DR1 are shown.

[0199] For example, Fig.11E and Fig.11H The display panel DP and the data driver DC are shown when viewed in a plan view.

[0200] For ease of explanation, Fig.11G The first mark MK1 and the second mark MK2 are shown as a plan view.

[0201] For simplicity, FIG. 11A to FIG. 11F Only the imaging part CHP of the alignment camera ACM is shown.

[0202] For ease of description, Fig.11G , only the pressing portion PSP, the first stage STG1 and the spectrum portion PLP of the bonding device BAP, the data driver DC, the display panel DP and the first adhesive layer CF1 are shown.

[0203] FIG. 11A to FIG. 11I The bonding device BAP, the display panel DP, the first adhesive layer CF1 and the data driver DC may be connected with Figure 1 , Fig. 7A , Figure 7B and Fig. 9 The bonding device BAP, the display panel DP, the first adhesive layer CF1, and the data driver DC are the same, and thus, repeated descriptions thereof will be omitted or simplified.

[0204] A method for coupling the data driver DC to the display panel DP according to one or more embodiments of the present disclosure will be described.

[0205] refer to Figure 1 , Figure 7B and Fig.11AThe pressing part PSP may include a first pressing part PSP1 and a second pressing part PSP2. The second pressing part PSP2 may be disposed on a bottom surface of the first pressing part PSP1. The length of the second pressing part PSP2 in the first direction DR1 may be smaller than the length of the first pressing part PSP1 in the first direction DR1.

[0206] The display panel DP may be disposed on the first stage STG1. The display panel DP may be disposed on the adsorption portion SPT and the transmission portion TRT. The first area AA1 may overlap the adsorption portion SPT. The adsorption holes SH defined in the adsorption portion SPT may be converted into a vacuum state by a motor SUM. When the adsorption holes SH are converted into a vacuum state, the display panel DP may be fixed on the adsorption portion SPT.

[0207] The second area AA2 may be disposed on the transmission portion TRT. The second area AA2 may be disposed on the first flat plate portion FR1. The second area AA2 may overlap the first groove GR1. The second area AA2 may be disposed on the spectrum portion PLP. Although not shown, Figure 7B The first mark MK1 may be disposed on the transmissive portion TRT. Figure 7B The first marker MK1 may be arranged on the spectral portion PLP. Figure 7B The first marker MK1 may overlap with the spectral portion PLP.

[0208] The first adhesive layer CF1 may be disposed on the transmissive portion TRT. The first adhesive layer CF1 may be disposed on the spectral portion PLP.

[0209] The data driver DC may be disposed on the second stage STG2. The data driver DC may be disposed in a third groove GR3 defined in the top surface of the second stage STG2. When the data driver DC is disposed on the second stage STG2, the first camera part CMP1 may capture an image of the data driver DC. The first camera part CMP1 may capture an image of the data driver DC to identify the position of the data driver DC on the second stage STG2.

[0210] refer to Fig. 11B , the second stage STG2 and the data driver DC may be moved to be adjacent to the first stage STG1. Specifically, the support portion DAR and the plate portion HPT connected to the support portion DAR may rotate around a rotation axis parallel to the third direction DR3. When the plate portion HPT rotates, the second stage STG2 and the data driver DC disposed on the second stage STG2 may rotate and move around a rotation axis parallel to the third direction DR3.

[0211] In an example, based on the movement of the data driver DC and the second stage STG2, the data driver DC may be disposed under the pressing portion PSP. The data driver DC may be disposed over the second camera portion CMP2.

[0212] When the data driver DC is disposed above the second camera part CMP2, the second camera part CMP2 may capture an image of the data driver DC. The second camera part CMP2 may capture an image of the data driver DC to identify a position of the data driver DC on the second stage STG2.

[0213] refer to Fig. 11C , after the second camera part CMP2 captures an image of the data driver DC, the technology described herein includes moving the pressing part PSP in the third direction DR3 based on the position of the data driver DC recognized by the first camera part CMP1 and the second camera part CMP2.

[0214] In an example, as a result of moving the pressing part PSP in the third direction DR3, the second pressing part PSP2 fixes the data driver DC to the pressing part PSP. For example, the second pressing part PSP2 may fix the data driver DC to the pressing part PSP through vacuum suction of the suction hole.

[0215] refer to Fig. 9 , Fig.11D and Fig.11E , after the pressing portion PSP fixes the data driver DC to the pressing portion PSP, the pressing portion PSP may move away from the driver PST in the third direction DR3. Thereafter, the pressing portion PSP may move in the first direction DR1 so that the pressing portion PSP is disposed on the first stage STG1. The pressing portion PSP may be disposed on the transmission portion TRT. The pressing portion PSP may be disposed on the spectrum portion PLP. The data driver DC may overlap with the spectrum portion PLP. The second mark MK2 may overlap with the spectrum portion PLP.

[0216] When the pressing part PSP is set on the spectrum part PLP, the imaging part CHP can capture images of the first mark MK1 set on the display panel DP and the second mark MK2 set on the data driver DC. Specifically, although not shown, the lighting device and the prism lens can be set in the spectrum part PLP. When the lighting device emits light toward the prism lens, the prism lens can disperse the light into a spectrum. The light dispersed into the spectrum may include near infrared rays irradiated toward the transmission part TRT. In an example, the near infrared rays may have a wavelength of about 0.72μm to about 1.3μm.

[0217] The near infrared ray irradiated toward the transmission part TRT may be reflected by the first marker MK1 and the second marker MK2. The reflected near infrared ray may be incident to the camera CM through a prism lens (not shown). The camera CM may obtain the image by converting light (e.g., including the reflected near infrared ray) into an electrical signal. Fig.11E The digitized image shown in . Therefore, the positions of the first marker MK1 and the second marker MK2 can be identified based on the digitized image. In some aspects, the camera CM can be a near infrared (NIR) camera capable of detecting and processing near infrared rays described herein.

[0218] When images of the first and second marks MK1 and MK2 are captured by the imaging part CHP, the middle controller MP and the upper controller TP may move in at least one of the first, second and third directions DR1, DR2 and DR3 based on positions of the first and second marks MK1 and MK2.

[0219] When the upper controller TP moves, the first stage STG1 connected to the upper controller TP moves in at least one of the first direction DR1, the second direction DR2 and the third direction DR3 in association with the movement of the upper controller TP. Therefore, the positions of the first mark MK1 and the second mark MK2 can be aligned based on the movement of the upper controller TP.

[0220] refer to Fig. 9 as well as FIG. 11F to FIG. 11H , after the first mark MK1 and the second mark MK2 are aligned, the technology described herein includes moving the pressing part PSP in the third direction DR3. When the pressing part PSP moves in the third direction DR3, the data driver DC is provided to (e.g., pressed to) the display panel DP. The data driver DC may be disposed on the second area AA2. The display panel DP and the data driver DC may overlap the transmissive part TRT. The data driver DC may be disposed on the first pad area PA1. The data driver DC may be disposed on the first adhesive layer CF1.

[0221] In an example of setting the data driver DC onto the display panel DP (eg, pressing the data driver DC onto the display panel DP), the data driver DC is electrically connected to the display panel DP, the first bump BP1 is connected to the first pad PD1, and the second bump BP2 is connected to the second pad PD2.

[0222] When the data driver DC and the display panel DP are electrically connected to each other, the imaging part CHP may capture images of the first marker MK1 and the second marker MK2. The images of the first marker MK1 and the second marker MK2 may be captured by the imaging part CHP at the same time (e.g., at the same time moment, the same duration, partially overlapping duration, etc.). The imaging part CHP may identify the positions of the first marker MK1 and the second marker MK2 based on data included in the captured image.

[0223] When the position of the first mark MK1 and the position of the second mark MK2 are identified, the technology described herein includes moving the middle controller MP and the upper controller TP in at least one of the first direction DR1, the second direction DR2, and the third direction DR3 based on the positions of the first mark MK1 and the second mark MK2. Therefore, the first stage STG1 can move. The display panel DP and the data driver DC disposed on the first stage STG1 can move in the same direction as the moving direction of the first stage STG1. Therefore, the positions of the first mark MK1 and the second mark MK2 can be aligned based on the movement of the first stage STG1.

[0224] According to some other techniques different from the techniques described according to the exemplary embodiments of the present disclosure, when the data driver DC is coupled to the display panel DP using an imaging part CHP that does not include a near infrared (NIR) camera as described herein, the first mark MK1 and the second mark MK2 of the data driver DC and the display panel DP may not be captured simultaneously.

[0225] Specifically, when the data driver DC is set on the display panel DP, light may be blocked by the display panel DP, so that the image of the second mark MK2 of the data driver DC cannot be captured. According to this structure, before the data driver DC is set on the display panel DP, the position of the first mark MK1 and the position of the second mark MK2 may be identified respectively. Based on the identified position of the first mark MK1 and the position of the second mark MK2, the data driver DC and the display panel DP may be aligned and connected to each other.

[0226] After the image of the second mark MK2 of the data driver DC is captured, when it is provided to the display panel DP, an error may occur in the process due to, for example, shaking of the pressing portion PSP or shaking of the first stage STG1. Therefore, the protruding electrode DC-BP of the data driver DC may fail to contact the first pad area PA1 (e.g., due to misalignment), and thus, the defect rate of the display panel DP may increase.

[0227] However, performing a bonding process using a bonding device according to an exemplary embodiment of the present disclosure supports simultaneous identification of the position of the first mark MK1 and the position of the second mark MK2. Specifically, the technology described herein supports simultaneous identification and alignment of the position of the first mark MK1 and the position of the second mark MK2 before the data driver DC is connected to the display panel DP. After aligning the first mark MK1 and the second mark MK2, the data driver DC can be connected to the display panel DP.

[0228] After the data driver DC is connected to the display panel DP, the imaging part CHP can simultaneously re-identify the position of the first mark MK1 and the position of the second mark MK2. The controller MDP can allow the position of the first stage STG1 to move based on the position of the first mark MK1 and the position of the second mark MK2. For example, the features described herein of the controller MDP support positioning the first stage STG1 based on the position of the first mark MK1 and the position of the second mark MK2.

[0229] Therefore, the first mark MK1 and the second mark MK2 may be aligned with each other. The bump electrode DC-BP of the data driver DC may be aligned with the first pad area PA1. The technology described herein supports improved alignment accuracy, thereby significantly reducing the defect rate of the display panel DP.

[0230] After aligning the first mark MK1 and the second mark MK2, the first adhesive layer CF1 may be cured. For example, the first adhesive layer CF1 may be thermally cured. In the example, as a result of curing the first adhesive layer CF1, the first and second pads PD1 and PD2 and the protruding electrode DC-BP are fixed to contact each other.

[0231] refer to Fig.11I , when the data driver DC is mounted on the display panel DP, the pressing portion PSP may move in the third direction DR3.

[0232] Fig.12 is a cross-sectional view of a bonding device according to another embodiment of the present disclosure.

[0233] For example, Fig.12 It is a side view when viewed in the first direction DR1.

[0234] refer to Fig.12 , a combination of one display panel DP and one data driver DC according to one or more embodiments of the present disclosure will be described.

[0235] For ease of explanation, Fig.12Only the pressing portion PSP, the first stage STG1 and the spectrum portion PLP (PLP′), the data driver DC, the display panel DP and the first adhesive layer CF1 of the bonding device BAP described herein are shown.

[0236] For example, for ease of explanation, the plan view shows Fig.12 The first mark MK1, the second mark MK2, the third mark MK3 and the fourth mark MK4.

[0237] Fig.12 The pressing portion PSP, the first stage STG1, the data driver DC, the display panel DP and the first adhesive layer CF1 may be connected to Fig.11G The pressing portion PSP, the first stage STG1, the data driver DC, the display panel DP, and the first adhesive layer CF1 are the same, and thus, repeated descriptions thereof will be omitted or simplified.

[0238] In addition, the main description Fig.12 and Fig.11G The difference.

[0239] refer to Fig.12 , the display panel DP may include a third mark MK3. The third mark MK3 may be disposed between the first marks MK1. The third mark MK3 may be disposed at the center between the first marks MK1 that are opposite to each other in the second direction DR2.

[0240] The data driver DC may include a fourth mark MK4. The fourth mark MK4 may be disposed between the second marks MK2. The fourth mark MK4 may be disposed at the center between the second marks MK2 that are opposite to each other in the second direction DR2.

[0241] When the data driver DC is connected to the display panel DP, each of the second marks MK2 may be disposed adjacent to a corresponding first mark MK1 of the first marks MK1. The fourth mark MK4 may be disposed to overlap the third mark MK3.

[0242] A plurality of spectrum parts PLP may be provided under the first stage STG 1. For example, three spectrum parts PLP are shown, but the number of spectrum parts PLP may not be limited thereto.

[0243] The three spectrum parts PLP may overlap with one display panel DP. That is, although not shown, the alignment camera ACM (see Figure 3 ) may include three imaging parts CHP corresponding to the three spectral parts PLP respectively.

[0244] When viewed in the first direction DR1, the spectrum portion PLP overlapping the edge of the display panel DP may overlap the first and second markers MK1 and MK2. The spectrum portion PLP overlapping the edge of the display panel DP may capture images of the first and second markers MK1 and MK2.

[0245] When viewed in the first direction DR1, the spectrum portion PLP' disposed in the middle of the spectrum portion PLP may overlap the third and fourth markers MK3 and MK4. The techniques described herein may include taking images of the third and fourth markers MK3 and MK4 using the spectrum portion PLP'.

[0246] When the third mark MK3 is disposed at the center between the first marks MK1 and the fourth mark MK4 is disposed at the center between the second marks MK2, further utilizing the third mark MK3 and the fourth mark MK4 to align the display panel DP and the data driver DC can provide significantly improved accuracy and significantly reduced complexity associated with aligning the display panel DP and the data driver DC. Therefore, the defect rate of the display panel DP can be reduced.
