Detailed Implementation

[0045] This invention can have various modifications and embodiments; specific embodiments are illustrated in the figures and described in detail. (Refer to...) Figure 1 The effects, features, and methods of achieving these effects and features of the invention will become clear from the detailed embodiments described below. However, the invention is not limited to the embodiments disclosed below and can be implemented in various ways.

[0046] Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing with reference to the drawings, the same or corresponding constituent elements will be given the same reference numerals, and repeated descriptions thereof will be omitted.

[0047] In the following embodiments, terms such as "first" and "second" are not limiting, but are used to distinguish one constituent element from other constituent elements.

[0048] In the following embodiments, singular expressions include multiple expressions unless the opposite is explicitly stated in the text.

[0049] The inclusion or presence of terms such as "in the following embodiments" to refer to the presence of features or constituent elements described in the specification does not preclude the possibility of adding more than one other feature or constituent element.

[0050] In the following embodiments, when a membrane, region, constituent element, or other part is located on or above other parts, this includes not only the case where it is directly located on other parts, but also the case where other membranes, regions, constituent elements, etc. exist between them.

[0051] In the accompanying drawings, the sizes of the constituent elements may be enlarged or reduced for ease of illustration. For example, the sizes and thicknesses of the constituent elements shown are for illustrative purposes only, and the invention is not necessarily limited to the illustrated cases.

[0052] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to the three axes of a Cartesian coordinate system, but can be interpreted as including a wider range. For example, the x-axis, y-axis, and z-axis can be orthogonal to each other, but can also refer to different directions that are not orthogonal to each other.

[0053] In cases where a particular embodiment can be implemented in different ways, the order of a specific step can be performed in a manner different from the order described. For example, two steps described consecutively can be performed substantially simultaneously, or they can be performed in the reverse order of the description.

[0054] Figure 1 This is a perspective view of a manufacturing apparatus for a display device according to an embodiment of the present invention. Figure 2 It means Figure 1 A three-dimensional view of the carrier shown. Figure 3 It is along Figure 1 A sectional view taken from line Ⅲ-Ⅲ′. Figure 4 It means Figure 3 A sectional view of part A.

[0055] Reference Figures 1 to 4 The manufacturing apparatus 100 for the display device may include a support 110, a substrate 120, a carrier 130, a roller 140, an alignment 150, a drive 160, a substrate drive 170, a rise and fall drive 190, and a process 180.

[0056] The support portion 110 supports the manufacturing apparatus 100 of the display device and may be provided with a base 120. At this time, the support portions 110 can be arranged in various directions. For example, a portion of the support portion 110 may be in a first direction (e.g., Figure 1 The support portion 110 is arranged longer in the X-axis direction, and another portion of the support portion 110 can be arranged in the second direction (e.g., the X-axis direction). Figure 1 They are arranged in a relatively long manner along the Y-axis.

[0057] The base 120 can be arranged on the support 110. In this case, the base 120 may include a first base 121, a second base 122, and a third base 123. The first base 121 may be located in the height direction of the support 110 (e.g., Figure 1 The second base 122 can be arranged in the support 110 to allow linear movement. In this case, the second base 122 can move linearly in the second direction. The third base 123 can be fixed to the support 110. In this case, the third base 123 can connect at least one of the first base 121 and the second base 122 that are far apart from each other, as well as the second base 122 that are far apart from each other.

[0058] The carrier 130 can be disposed on the substrate 120 and can be moved along the substrate 120 in various directions. For example, the carrier 130 can be moved along a first direction on the substrate 120. The upper surface of the carrier 130 can be flat to accommodate a substrate for placement on the carrier 130.

[0059] Roller portion 140 can be disposed between carrier 130 and base 120 to support carrier 130. In this case, roller portion 140 can be connected to one side of carrier 130 opposite to base 120. Roller portion 140 may include: roller bracket 141, fixed to carrier 130; and roller 142, rotatably connected to roller bracket 141. Furthermore, roller portion 140 may include: rotating shaft 143, rotatably connecting roller bracket 141 and roller 142; and bearing (not shown), rotatably connecting rotating shaft 143 to roller bracket 141. As described above, roller 142 includes a core of a hard material such as metal, and may include an outer skin of an elastic material such as rubber, urethane, or silicone surrounding the outer surface of the core.

[0060] The carrier 130 may have multiple roller portions 140 as described above. The multiple roller portions 140 may be arranged on one side of the carrier 130 in a way that they are far apart from each other. For example, if the carrier 130 is quadrilateral, the multiple roller portions 140 may be arranged at the corner portions of the carrier 130. Alternatively, the multiple roller portions 140 may be arranged far apart from each other on the outer contour portion of the carrier 130.

[0061] The alignment part 150 is disposed between the base 120 and the carrier 130, which can not only align the position of the carrier 130, but also guide the path of the carrier 130 when it moves. In this case, the alignment part 150 can align the position of the carrier 130 by means of magnetic force with repulsive and attractive forces.

[0062] As described above, the alignment portion 150 can be disposed on the outer contour of the roller portion 140. That is, with the carrier 130 as a reference, the alignment portion 150 can be disposed on the outer contour portion of the carrier 130, and the roller portion 140 can be disposed on the carrier 130 closer to the center portion of the carrier 130 than the alignment portion 150. As another embodiment, the alignment portion 150 can also be disposed on the inner side of the roller portion 140. That is, the alignment portion 150 can be disposed on the carrier 130 closer to the center of the carrier 130 than the roller portion 140, starting from the outer contour of the carrier 130. Hereinafter, for ease of explanation, a detailed description will focus on the case where the alignment portion 150 is disposed on the outer contour of the roller portion 140.

[0063] The alignment portion 150 may include a first guide portion 151 and a second guide portion 152 configured to face each other. In this case, one of the first guide portion 151 and the second guide portion 152 may be connected to the substrate 120, and the other of the first guide portion 151 and the second guide portion 152 may be connected to the carrier 130. Hereinafter, for ease of explanation, a detailed description will focus on the case where the first guide portion 151 is configured on the substrate 120 and the second guide portion 152 is configured on the carrier 130.

[0064] As one embodiment, a first guide portion 151 and a second guide portion 152 may be provided, with the first guide portion 151 being arranged to be longer in the length direction of the base 120. Furthermore, the second guide portion 152 may be arranged to be longer in the length direction of the carrier 130. In this case, the first guide portion 151 and the second guide portion 152 may be arranged to be longer in the movement direction of the carrier 130. As another embodiment, only one of the first guide portion 151 and the second guide portion 152 may be provided, and the other of a plurality of first guide portions 151 and second guide portions 152 may be provided. In this case, one of the first guide portion 151 and the second guide portion 152 may be arranged to be longer in the movement direction of the carrier 130 as described above. In this case, the other of the first guide portion 151 and the second guide portion 152 may be arranged to be spaced apart from each other in the movement direction of the carrier 130. Hereinafter, for ease of explanation, a detailed description will focus on the case where a plurality of first guide portions 151 are arranged to be spaced apart from each other and a second guide portion 152 is arranged to be longer in the movement direction of the carrier 130.

[0065] As described above, the first guide portion 151 and the second guide portion 152 can generate attraction and repulsion forces between each other through magnetic force. Specifically, the first guide portion 151 may include a first magnetic portion 151-1 and a second magnetic portion 151-2 configured to be far apart from each other, and the second guide portion 152 may include a third magnetic portion 152-1 and a fourth magnetic portion 152-2 configured to be far apart from each other, wherein the third magnetic portion 152-1 faces the first magnetic portion 151-1, and the fourth magnetic portion 152-2 faces the second magnetic portion 151-2.

[0066] As described above, the polarities of the first magnetic section 151-1 and the third magnetic section 152-1 can be different from each other. Furthermore, the polarities of the second magnetic section 151-2 and the fourth magnetic section 152-2 can be different from each other. For example, if the first magnetic section 151-1 and the fourth magnetic section 152-2 have an N pole polarity, the second magnetic section 151-2 and the third magnetic section 152-1 can have an S pole polarity. As another embodiment, if the first magnetic section 151-1 and the fourth magnetic section 152-2 have an S pole polarity, the second magnetic section 151-2 and the third magnetic section 152-1 can have an N pole polarity. As described above, the first magnetic section 151-1 and the third magnetic section 152-1, which face each other, can attract each other, while the first magnetic section 151-1 and the fourth magnetic section 152-2, which are arranged diagonally opposite each other, can repel each other. Furthermore, the second magnetic section 151-2 and the fourth magnetic section 152-2 can form an attractive force to each other, and the second magnetic section 151-2 and the third magnetic section 152-1, which are arranged diagonally opposite each other, can form a repulsive force to each other. In the case described above, the first magnetic section 151-1 to the fourth magnetic section 152-2 may include permanent magnets.

[0067] When the first magnetic units 151-1 to the fourth magnetic units 152-2 are configured as described above, the carrier 130 can be automatically aligned when it is placed on the substrate 120. Specifically, when the carrier 130 is placed on the substrate 120, the carrier 130 may move or change position due to external forces. When the first magnetic unit 151-1 and the third magnetic unit 152-1 move further apart, or the second magnetic unit 151-2 and the fourth magnetic unit 152-2 move further apart, the first magnetic unit 151-1 can be arranged to correspond to the third magnetic unit 152-1, and the second magnetic unit 151-2 can be arranged to correspond to the fourth magnetic unit 152-2, through the attraction between the first magnetic unit 151-1 and the third magnetic unit 152-1, and the attraction between the second magnetic unit 151-2 and the fourth magnetic unit 152-2. Furthermore, when the first magnetic part 151-1 and the fourth magnetic part 152-2 approach each other, or when the second magnetic part 151-2 and the third magnetic part 152-1 approach each other, they generate a repulsive force against each other, thereby causing the first magnetic part 151-1 and the fourth magnetic part 152-2 to move further apart, or causing the second magnetic part 151-2 and the third magnetic part 152-1 to move further apart.

[0068] By using the attraction and repulsion forces generated between the magnetic parts as described above, the position of the carrier 130 can be aligned to a predetermined position.

[0069] The drive unit 160 can be disposed between the base 120 and the carrier 130. The drive unit 160 may include a linear motor. Specifically, the drive unit 160 may include a scale 161 disposed on the base 120 and a slider 162 disposed on the carrier 130. In this case, the scale 161 may include an electromagnet with a coil. The slider 162 may include a permanent magnet disposed opposite to the scale 161. At this time, the slider 162 may be configured to be slidably connected to the scale 161 or not connected to the scale 161 but away from the scale 161. Hereinafter, for ease of explanation, a detailed description will focus on the case where the scale 161 is not connected to the slider 162 but away from the slider 162.

[0070] The base drive unit 170 can be disposed between the support unit 110 and the base 120 and cause the base 120 to move linearly. In this case, the base drive unit 170 can be formed in various forms. For example, the base drive unit 170 may include a cylinder connected to the base 120. As another embodiment, the base drive unit 170 may include: a moving module connected to the base 120; a ball screw connected to the moving module to cause the moving module to move linearly; and a motor connected to the ball screw. As yet another embodiment, the base drive unit 170 may also include a linear motor, similar to the drive unit 160 described above. Hereinafter, for ease of explanation, a detailed description will focus on the case where the base drive unit 170 includes a linear motor.

[0071] The riser / faller drive unit 190 can be disposed on the support unit 110 and connected to the first base 121, thereby enabling the first base 121 to perform riser and fall movements. In this case, the riser / faller drive unit 190 is the same as or similar to the base drive unit 170, so detailed description is omitted. Hereinafter, for ease of explanation, a detailed description will be provided focusing on the case where the riser / faller drive unit 190 includes a linear motor.

[0072] The process unit 180 can be connected to the support unit 110. In this case, the process unit 180 holds the substrate transferred via the second substrate 122 and can perform various processes on the substrate. Although not shown, the process unit 180 may include a chamber according to the processes performed on the substrate. Furthermore, the process unit 180 may include a worktable (not shown) with the same or similar shape as the substrate 120. As another embodiment, the process unit 180 may also include a sensing unit (not shown) that senses errors or contamination on the substrate. In this case, the process unit 180 is not limited to the above-described cases and may include all devices that can perform processes such as forming each layer of the display device (not shown) and checking for contamination in each layer during the manufacturing of the display device (not shown).

[0073] On the other hand, when the manufacturing apparatus 100 for the display device described above is in operation, the lifting and lowering drive unit 190 can operate when a substrate is supplied from the outside, thereby lowering the first substrate 121. At this time, a carrier 130, such as a robotic arm separately provided externally, can be used to supply the substrate to the first substrate 121.

[0074] In the case described above, the carrier 130 can be automatically aligned on the first substrate 121. In particular, in the case described above, when the substrate is placed on the carrier 130, when an external force is applied to the carrier 130, as described above, the second guide portion 152 on the carrier 130 and the first guide portion 151 on the first substrate 121 will return to their predetermined positions due to mutual attraction and repulsion, even if the carrier 130 moves.

[0075] If the substrate is disposed on the carrier 130, the rising and falling drive unit 190 can raise the first base 121. Then, if the first base 121 and the second base 122 are disposed at the same height, the scale 161 on the first base 121 operates, allowing the carrier 130 to be moved from the first base 121 to the second base 122. At this time, the roller 140 can maintain a certain distance between the carrier 130 and the first base 121 and the second base 122 when the carrier 130 moves. Furthermore, the first guide 151 and the second guide 152 form an attraction to each other, thereby allowing the roller 140 to be in close contact with the base 120. In this case, the first guide 151 on the first base 121 and the first guide 151 on the second base 122 can prevent the carrier 130 from leaving the movement path when the carrier 130 moves. That is, in this case, the carrier 130 can... Figure 1 The carrier 130 moves in one of the X-axis or Y-axis directions. In this case, the attractive and repulsive forces between the first guide 151 and the second guide 152 allow the carrier 130 to return to the predetermined movement path if it deviates from it. The interaction between the first guide 151 and the second guide 152 is the same as described above, therefore a detailed explanation is omitted.

[0076] If the carrier 130 is positioned on the second base 122, the base drive unit 170 operates, moving the second base 122 to a position corresponding to the process unit 180. Then, the scale 161 on the second base 122 operates, moving the carrier 130 from the second base 122 to the process unit 180. At this time, as described above, the first guide unit 151 and the second guide unit 152 can guide the movement of the carrier 130. Furthermore, the roller unit 140 can maintain a constant gap between the carrier 130 and the second base 122, and between the worktable of the process unit 180 and the carrier 130.

[0077] The process unit 180 can perform various processes on the substrate. When the work of the process unit 180 is completed, the substrate is transferred to the second substrate 122 again. At this time, other scales are provided in the process unit 180, so that the carrier 130 can be moved.

[0078] If the carrier 130 is disposed on the second substrate 122, the substrate driving unit 170 can restore the second substrate 122 to its original state or transfer it to other process units 180.

[0079] After each of the processes described above is completed, the carrier 130 can be transferred from the second substrate 122 to the third substrate 123. Then, it can be transferred from the third substrate 123 to a different second substrate 122 or to a different first substrate 121. The method of moving the carrier 130 from the third substrate 123 is the same as or similar to the method of moving the carrier 130 from the second substrate 122 described above, therefore a detailed description is omitted.

[0080] The substrate, having completed the processes described above, can finally be moved to the first substrate 121 positioned at the end. At this point, with... Figure 1 The first base 121, positioned on the left side as a reference, houses the substrate supplied from the outside, so as to Figure 1 The first substrate 121, positioned on the right side as a reference, can deliver a substrate supplied from the second substrate 122 or the third substrate 123 to the outside. In this case, the first substrate 121 that delivers the substrate to the outside can operate similarly to the first substrate 121 that receives the substrate from the outside.

[0081] The display device manufacturing apparatus 100 described above can prevent the carrier 130 from deviating from a predetermined movement path when the carrier 130 moves. Furthermore, if the position of the carrier 130 is deviated, the display device manufacturing apparatus 100 can automatically align the position of the carrier 130 to the correct position using magnetic attraction and repulsion.

[0082] The display device manufacturing apparatus 100 can tightly attach the roller portion 140 to the base 120 when the carrier 130 moves, thereby preventing the carrier 130 from shaking or vibrating when it moves.

[0083] The display device manufacturing apparatus 100 does not have any other bonding structure between the carrier 130 and the substrate when moving between substrates that are far apart from each other, so substrates that are different from each other can be moved freely.

[0084] Figure 5 This is a cross-sectional view showing a portion of a manufacturing apparatus for a display device according to other embodiments of the present invention.

[0085] Reference Figure 5 The manufacturing apparatus for the display device (not shown) can be used with the aforementioned Figures 1 to 4 The manufacturing apparatus described herein is similar. The alignment section 150 may include a first guide section 151 and a second guide section 152. In this case, one of the first guide section 151 and the second guide section 152 may include an electromagnet. Hereinafter, for ease of explanation, a detailed description will focus on the case where the first guide section 151 includes an electromagnet.

[0086] When the first guide portion 151 includes an electromagnet, the first magnetic portion 151-1 and the second magnetic portion 151-2 may also include electromagnets. In this case, the polarity of the first magnetic portion 151-1 and the polarity of the second magnetic portion 151-2 may be opposite to the polarity of the third magnetic portion 152-1 and the fourth magnetic portion 152-2, respectively.

[0087] In this case, the manufacturing apparatus for the display device can be used in conjunction with the... Figures 1 to 4 The operation is similar to that described above. That is, as the carrier 130 moves, the carrier 130 can perform linear movement as the scale 161 on the base 120 is operated. In addition, the roller 140 can maintain a constant gap between the base 120 and the carrier 130.

[0088] Therefore, the manufacturing apparatus for the display device can prevent the carrier 130 from deviating from the predetermined movement path when the carrier 130 moves. Furthermore, the manufacturing apparatus can automatically align the carrier 130 to the correct position using magnetic attraction and repulsion if the carrier 130's position is deviated.

[0089] The manufacturing apparatus for the display device can make the roller 140 closely attached to the base 120 when the carrier 130 moves, thereby preventing the carrier 130 from shaking or vibrating when it moves.

[0090] The manufacturing apparatus for the display device does not have any other bonding structure between the carrier 130 and the substrate when moving between substrates that are far apart from each other, so substrates that are different from each other can be moved freely.

[0092] Reference Figures 6 to 9 The manufacturing apparatus 100 for the display device may include a support 110, a base 120, a carrier 130, a roller 140, an alignment 150, a drive 160, a rise / fall drive 190, and a process 180. At this time, the support 110, carrier 130, rise / fall drive 190, and process 180 are integrated with the components described above. Figures 1 to 4 The situation described in the previous section is similar, so detailed explanations are omitted.

[0093] The substrate 120 may include a first substrate 121, a second substrate 122, a third substrate 123, and a fourth substrate 124. The first substrate 121 may be disposed at both ends of the manufacturing apparatus 100 of the display device, thereby allowing it to rise and fall in the height direction of the support 110. The second substrate 122 may be connected to the first substrate 121, and the carrier 130 may change direction on the second substrate 122. For example, the carrier 130 may change direction on the second substrate 122 from a first direction (e.g., ...). Figure 6 The X-axis direction is converted into a second direction (e.g., Figure 6 (Y-axis direction). Furthermore, the carrier 130 can convert the direction from the second direction to the first direction. The third substrate 123 can be arranged adjacent to the second substrate 122 in the first direction. The fourth substrate 124 can be arranged adjacent to the second substrate 122 in the second direction. That is, based on the second substrate 122, the second substrate 122 is configured such that it is adjacent to the third substrate 123 in the first direction and to the fourth substrate 124 in the second direction.

[0094] The roller portion 140 can be rotatably connected to the carrier 130. In this case, the roller portion 140 can be connected to the carrier 130. Figures 1 to 4 The situation described in the previous example is similar. In this case, the roller 140 can be rotatably connected to the carrier 130. Alternatively, the roller 140 can be connected to a separately provided rotation drive unit to automatically change the direction of the roller 140 when the direction of movement of the carrier 130 is changed. The rotation drive unit may include a motor.

[0095] Alignment portion 150 can be disposed between carrier 130 and base 120. In this case, alignment portion 150 may include a first guide portion 151, a second guide portion 152, a third guide portion 153, and a fourth guide portion 154. The first guide portion 151, the second guide portion 152, and the fourth guide portion 154 can be rotatably connected to carrier 130 or base 120. The third guide portion 153 is configured to be fixed to carrier 130 or base 120. Hereinafter, for ease of explanation, a detailed description will focus on the case where the first guide portion 151 is disposed on the second base 122, the second guide portion 152 is disposed on carrier 130, the third guide portion 153 is disposed on the first base 121 and the third base 123, and the fourth guide portion 154 is disposed on the fourth base 124.

[0096] The first guide portion 151 can be configured to rotate on the second base 122. In this case, the first guide portion 151 can be connected to a first guide rotation drive portion 191 disposed on the second base 122. The first guide rotation drive portion 191 can rotate the first guide portion 151 when the carrier 130 changes direction. In this case, as described... Figures 1 to 4As described in the document, the first guide portion 151 may include a first magnetic portion 151-1 and a second magnetic portion 151-2.

[0097] The second guide portion 152 can be configured to rotate within the carrier 130. In this case, the second guide portion 152 can rotate together with the first guide portion 151 when the first guide portion 151 rotates. At this time, the second guide portion 152 may include a third magnetic portion 152-1 and a fourth magnetic portion 152-2. The third magnetic portion 152-1 and the fourth magnetic portion 152-2 can then interact with the carrier 130. Figures 1 to 4 The situations described herein are the same or similar.

[0098] The third guide portion 153 can be disposed on the third base 123. In this case, the third guide portion 153 can be arranged in a longer manner in the first direction and can be configured to be fixed to the third base 123. The third guide portion 153 is configured to face the second guide portion 152 when the carrier 130 moves, thereby not only aligning the position of the carrier 130 but also guiding its movement. Although not shown, the third guide portion 153 can, similarly to the first guide portion 151, include a fifth magnetic portion (not shown) and a sixth magnetic portion (not shown) with opposite polarities. In this case, when the second guide portion 152 and the third guide portion 153 are configured to face each other, the fifth magnetic portion can be configured to face the third magnetic portion 152-1, and the sixth magnetic portion can be configured to face the fourth magnetic portion 152-2. At this time, the polarity of the fifth magnetic part can be different from that of the third magnetic part 152-1, and the polarity of the sixth magnetic part can be different from that of the fourth magnetic part 152-2. In this case, the fifth magnetic part and the third magnetic part 152-1 can form an attractive force to each other, and the fifth magnetic part and the fourth magnetic part 152-2 can form a repulsive force to each other. Furthermore, the sixth magnetic part and the fourth magnetic part 152-2 can form an attractive force to each other, and the sixth magnetic part and the third magnetic part 152-1 can form a repulsive force to each other.

[0099] The fourth guide portion 154 can be configured to rotate on the fourth base 124. The fourth guide portion 154 can be arranged elongated in the second direction and fixed to the fourth base 124. The fourth guide portion 154 is configured to face the second guide portion 152 when the carrier 130 moves along the second direction, thereby not only aligning the position of the carrier 130 but also guiding its movement. This fourth guide portion 154 may include a seventh magnetic portion (not shown) and an eighth magnetic portion (not shown). In this case, the seventh and eighth magnetic portions may differ from the first magnetic portion 151-1 and the second magnetic portion 151-2 only in their orientation, while remaining identical in other aspects. The fourth guide portion 154, as described above, can be connected to a second guide rotation drive portion (not shown) configured on the fourth base 124. In this case, the second guide rotation drive portion may be the same as or similar to the first guide rotation drive portion 191.

[0100] As described above, the first guide portion 151 to the fourth guide portion 154 may each include one of a permanent magnet and an electromagnet, as explained above.

[0101] The drive unit 160 may include a scale (not shown) disposed on one of the base 120 and the carrier 130, and a slider (not shown) disposed on the other of the base 120 and the carrier 130. Hereinafter, for ease of explanation, a detailed description will be provided focusing on the case where the scale is disposed on the base 120 and the slider is disposed on the carrier 130.

[0102] The scale and the slider described above can rotate together with the first guide 151 described above. In this case, when one of the scale and the slider rotates, the scale operates such that the polarities of the opposing portions, i.e., the scale portion and the slider portion, are different, thereby causing one of the scale or the slider to rotate together with the other. As another embodiment, to prevent the scale and the slider from rotating, they can also be fixed to the base 120 and the carrier 130. Hereinafter, for ease of explanation, a detailed description will focus on the case where the scale and the slider are fixed to the base 120 and the carrier 130.

[0103] The scale may include: a first scale 161 arranged on the base 120 along a first direction; and a second scale 163 arranged on the base 120 along a second direction. In this case, the first scale 161 may be configured to be mutually distanced from the first base 121, the second base 122, and the third base 123 arranged in the first direction. Furthermore, the first scale 161 may be arranged on a fourth base 124 in the first direction. The second scale 163 may be configured to be distanced from the second base 122 and the fourth base 124 along the second direction. In this case, the first scale 161 and the second scale 163 may be configured on the outer contour portion of the base 120 to minimize interference with other components disposed on the lower surface of the carrier 130 when the carrier 130 moves. As another embodiment, the first scale 161 and the second scale 163 may be configured on the central portion of the base 120 disposed between the second guide portions 152 of the base 120 to minimize interference with other components disposed on the lower surface of the carrier 130 when the carrier 130 moves. For ease of explanation, the following detailed description will focus on the case where the first scale 161 and the second scale 163 are arranged on the outer contour of the base 120.

[0104] As described above, one of the first scale 161 and the second scale 163 can operate when the carrier 130 moves along one of the first and second directions. At this time, the other of the first scale 161 and the second scale 163 can cease operation. The first scale 161 and the second scale 163, as described above, can be configured in different directions from each other. For example, the first scale 161 can be configured in the first direction, and the second scale 163 can be configured in the second direction. In particular, the first scale 161 and the second scale 163 can be configured to form a right angle with each other.

[0105] The slider may include a first slider 162 and a second slider 164 disposed on the carrier 130. In this case, the first slider 162 is configured to face the first scale 161, and the second slider 164 is configured to face the second scale 163. In this configuration, the first slider 162 may be disposed in a first direction, and the second slider 164 may be disposed in a second direction. As described above, the first slider 162 and the second slider 164 may be configured to form a right angle with each other. In this case, the first slider 162 and the second slider 164 may be disposed on the outer contour of the carrier 130, such that they do not overlap with the first guide portion 151, the third guide portion 153, and the fourth guide portion 154. As another embodiment, the first slider 162 and the second slider 164 may be disposed on the central portion of the carrier 130, such that they do not overlap with the first guide portion 151, the third guide portion 153, and the fourth guide portion 154. In this case, the first slider 162 and the second slider 164 may be arranged so that they do not overlap with each other. For ease of explanation, the following detailed description will focus on the case where the first slider 162 and the second slider 164 are arranged on the outer contour of the carrier 130.

[0106] On the other hand, when the display device manufacturing apparatus 100 is operating, if a substrate is supplied from the outside, the first substrate 121 can be lowered and the substrate can be placed on the carrier 130 by an external robotic arm or the like.

[0107] If the lifting / lowering drive unit 190 raises the first base 121, positioning it at the same height as the second base 122, then when the first scale 161 on the first base 121 is activated, the carrier 130 can move in the first direction. Specifically, when the first scale 161 on the first base 121 is activated, it provides electromagnetic force to the first slider 162, thereby moving the carrier 130 in the first direction. At this time, the second guide portion 152 and the first guide portion 151 on the first base 121 are configured to correspond vertically to each other, thereby preventing the carrier 130 from swaying or falling off the movement path. Furthermore, the second guide portion 152 and the first guide portion 151 on the first base 121 can provide attraction towards the first base 121, causing the roller portion 140 to be in close contact with the upper surface of the first base 121.

[0108] If the carrier 130 is disposed on the second substrate 122, the carrier 130 can move in the first direction to move to the third substrate 123, or the carrier 130 can move in the second direction to move to the fourth substrate 124.

[0109] First, when the carrier 130 moves from the first base 121 to the second base 122 and then from the second base 122 to the third base 123, the first scale 161 on the second base 122 is activated, allowing the carrier 130 to move from the second base 122 to the third base 123. At this time, with the first scale 161 activated, the second scale 163 on the second base 122 may not be activated. In this case, the first guide portion 151 and the second guide portion 152 are arranged in a first direction, thereby guiding the movement of the carrier 130. Furthermore, when the carrier 130 is positioned on the second base 122, the first guide portion 151 and the second guide portion 152 exert attractive and repulsive forces on each other, thereby aligning the position of the carrier 130.

[0110] Conversely, when the carrier 130 moves from the first base 121 to the second base 122 and then from the second base 122 to the fourth base 124, the first guide rotation drive unit 191 operates, thereby causing the first guide portion 151 to rotate and align itself in the second direction. Thus, the longitudinal direction and the second direction of the first guide portion 151 can be parallel to each other. If the first guide portion 151 rotates, the second guide portion 152 can rotate in the same direction as the first guide portion 151 due to the attraction and repulsion forces with it. If the first guide portion 151 is aligned in a straight line in the second direction, the second guide portion 152 can also be aligned in a straight line in the second direction to correspond to the first guide portion 151. In this case, the second guide portion 152 can form a straight line with the fourth guide portion 154 in the second direction. As described above, when the first guide portion 151 and the second guide portion 152 rotate, the roller portion 140 can also rotate. In this case, the roller portion 140 can rotate with respect to the axis connected to the carrier 130. In this case, a separate motor is connected to the shaft of the roller 140, allowing the roller 140 to rotate. The shaft is rotatable on the carrier 130, so that the carrier 130 can rotate when moving in the second direction after the first guide 151 rotates. As described above, the second scale 163 can operate after the first guide 151 rotates. At this time, with the operation of the second scale 163, the carrier 130 can move in the second direction. The operation of the first scale 161 can be stopped. When the carrier 130 moves along the second direction, the carrier 130 can move from the second base 122 to the fourth base 124. When the carrier 130 is positioned on the fourth base 124, the first scale 161 on the fourth base 124 can move the carrier 130 to the process section 180. The second guide rotation drive can rotate the fourth guide 154, causing the length direction of the fourth guide 154 to change from the second direction to the first direction. When the fourth guide 154 rotates, the first guide 151, which faces the fourth guide 154, can rotate. The first guide 151 and the fourth guide 154 can be arranged in the first direction. If the first scale 161 on the fourth base 124 is working, the carrier 130 can be moved from the fourth base 124 to the process section 180.

[0111] After the process is performed on the substrate in process section 180, the carrier 130 on which the substrate is placed can be moved from process section 180 to the fourth base 124. Then, the second guide rotation drive unit operates, which can align the fourth guide 154 from the first direction to the second direction, and then make the second scale 163 on the fourth base 124 work, thereby moving the carrier 130 from the fourth base 124 to the second base 122.

[0112] The carrier 130 can move from the second substrate 122 to the third substrate 123 or from the second substrate 122 to a location disposed on the second substrate 122 after moving to the second substrate 122. Figure 6 The fourth base 124 below. At this time, as described above, after the direction of the first guide 151 is aligned with the moving direction of the carrier 130 by the first guide rotation drive 191, the first scale 161 or the second scale 163 on the second base 122 is activated, thereby moving the carrier 130.

[0113] Therefore, the display device manufacturing apparatus 100 can prevent the carrier 130 from deviating from the predetermined movement path when the carrier 130 moves. Furthermore, if the position of the carrier 130 deviates, the display device manufacturing apparatus 100 can automatically align the carrier 130 to the correct position using magnetic attraction and repulsion.

[0114] The display device manufacturing apparatus 100 can make the roller 140 closely contact the base 120 when the carrier 130 moves, thereby preventing the carrier 130 from shaking or vibrating when it moves.

[0115] The display device manufacturing apparatus 100 does not have any other bonding structure between the carrier 130 and the substrate when moving between substrates that are far apart from each other, so substrates that are different from each other can be moved freely.

[0116] Figure 10 This is a plan view illustrating a display device according to an embodiment of the present invention. Figure 11 It is along Figure 10 A sectional view taken from the BB' line.

[0117] Reference Figure 10 as well as Figure 11 The display device 20 can define a display area DA and a non-display area NDA, the outline of the display area DA, on the substrate 21. A light-emitting component can be disposed in the display area DA, and power wiring (not shown) can be disposed in the non-display area NDA. Furthermore, a pad C can be disposed in the non-display area NDA.

[0118] The following detailed description focuses on the case where the display device 20 includes a substrate 21, a thin-film transistor (TFT), an organic light-emitting element (OLED), and a packaging component (not shown).

[0119] The substrate 21 may include glass or a polymer resin. The polymer resin may include polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate (PEN), polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, or cellulose acetate propionate, etc. The substrate 21 comprising the polymer resin may have bendable, rollable, or foldable properties. The substrate 21 may be a multilayer structure comprising a layer containing the aforementioned polymer resin and an inorganic layer (not shown).

[0120] A thin-film transistor (TFT) can be formed on the substrate 21, and a passivation film 27 is formed to cover the TFT, on which an organic light-emitting element 28 is formed.

[0121] A buffer layer 22, composed of organic and / or inorganic compounds, can also be formed on the upper surface of the substrate 21. This buffer layer can be made of SiO₂. x (x≥1), SiN x (x≥1) is formed.

[0122] After the active layer 23 arranged in a predetermined pattern is formed on the buffer layer 22, the active layer 23 is buried by the gate insulating layer 24. The active layer 23 may also have a source region 23A and a drain region 23C, and also includes a channel region 23B therebetween.

[0123] This active layer 23 can be formed to contain various materials. For example, the active layer 23 can contain inorganic semiconductor materials such as amorphous silicon or crystalline silicon. As another example, the active layer 23 can contain oxide semiconductor materials. As yet another example, the active layer 23 can contain organic semiconductor materials. However, for ease of explanation, the following detailed description will focus on the case where the active layer 23 is formed of amorphous silicon.

[0124] This active layer 23 can be formed by crystallizing an amorphous silicon film on the buffer layer 22 to form a polycrystalline silicon film, and then patterning the polycrystalline silicon film. The active layer 23 can be doped with impurities in its source region 23A and drain region 23C according to the type of TFT, such as a driving TFT (not shown) or a switching TFT (not shown).

[0125] A gate electrode 25 corresponding to the active layer 23 and an interlayer insulating layer 26 filling the gate electrode 25 are formed on the upper surface of the gate insulating layer 24.

[0126] Furthermore, after forming contact hole H1 in interlayer insulating layer 26 and gate insulating layer 24, source electrode 27A and drain electrode 27B are formed on interlayer insulating layer 26 so that they are in contact with source region 23A and drain region 23C respectively.

[0127] A passivation film 27 is formed on the upper part of the thin-film transistor TFT thus formed, and a pixel electrode 28A of an organic light-emitting element (OLED) 28 is formed on the upper part of the passivation film 27. The pixel electrode 28A contacts the source electrode 27A of the thin-film transistor TFT through a through-hole H2 formed in the passivation film 27. The passivation film 27 can be formed as a single layer or two or more layers of inorganic and / or organic materials. It can be formed as a planarization film independent of the bending of the lower film to make the upper surface flat, or it can be formed to have bending along the bending of the lower film. Furthermore, the passivation film 27 is preferably formed of a transparent insulator to achieve a resonance effect.

[0128] After forming pixel electrode 28A on passivation film 27, pixel definition film 29 is formed by organic and / or inorganic materials to cover pixel electrode 28A and passivation film 27, and an opening is formed to expose pixel electrode 28A.

[0129] Furthermore, at least an intermediate layer 28B and a counter electrode 28C are formed on the pixel electrode 28A. Alternatively, the counter electrode 28C may be formed over the entire surface of the display area DA. In this case, the counter electrode 28C may be formed on the intermediate layer 28B and the pixel definition film 29. Hereinafter, for ease of explanation, a detailed description will focus on the case where the counter electrode 28C is formed on the intermediate layer 28B and the pixel definition film 29.

[0130] Pixel electrode 28A functions as an anode, and counter electrode 28C functions as a cathode. Of course, the polarity of these pixel electrodes 28A and counter electrode 28C can also be reversed.

[0131] The pixel electrode 28A and the counter electrode 28C can be insulated from each other through the intermediate layer 28B, and light can be emitted from the organic light-emitting layer by applying voltages of different polarities to the intermediate layer 28B.

[0132] The intermediate layer 28B may include an organic emission layer. Alternatively, the intermediate layer 28B may include an organic emission layer, and may also include at least one of a hole injection layer (HIL), a hole transport layer, an electron transport layer, and an electron injection layer. This embodiment is not limited to this; the intermediate layer 28B may also include an organic emission layer and further include various other functional layers (not shown).

[0133] It can have multiple intermediate layers 28B as described above, and the multiple intermediate layers 28B can form a display area DA. At this time, the multiple intermediate layers 28B can be configured to be far apart from each other within the display area DA.

[0134] On the other hand, a unit pixel is formed by multiple sub-pixels, which can emit light of various colors. For example, multiple sub-pixels can have sub-pixels that emit red, green, and blue light respectively, or they can have sub-pixels that emit red, green, blue, and white light (not shown).

[0135] The above Figure 1 The manufacturing apparatus 100 of the display device shown can form various layers in the display area DA. For example, the manufacturing apparatus 100 can form at least one of at least one of the intermediate layers 28B in the display area DA. For example, the manufacturing apparatus 100 can form at least one of the following in the intermediate layer 28B: an organic light-emitting layer, a hole injection layer, a hole transport layer, an electron injection layer, an electron transport layer, and a functional layer.

[0136] An upper layer (not shown) comprising an organic material may be included on the counter electrode 28C as described above. In this case, the upper layer may be disposed between the encapsulation substrate (described later) and the counter electrode 28C, or between the thin-film encapsulation layer E and the counter electrode 28C.

[0137] The upper layer can be a layer provided to protect the counter electrode 28C while improving light extraction efficiency. The upper layer may include an organic material with a refractive index higher than that of the counter electrode 28C. Alternatively, the upper layer can be formed by stacking layers with different refractive indices. For example, the upper layer can be formed by stacking a high-refractive-index layer / a low-refractive-index layer / a high-refractive-index layer. In this case, the refractive index of the high-refractive-index layer can be 1.7 or higher, and the refractive index of the low-refractive-index layer can be 1.3 or lower.

[0138] The upper layer may further include LiF. Alternatively, the upper layer may further include silicon oxide (SiO2) or silicon nitride (SiN). x Inorganic insulating materials such as .

[0139] On the other hand, the encapsulation component can be formed in various forms. For example, the encapsulation component can be formed of the same or similar material as the substrate 21, and can include an encapsulation substrate (not shown) configured to face the substrate 21. Furthermore, the encapsulation component can include a sealing portion disposed between the substrate 21 and the encapsulation substrate, connecting the substrate 21 and the encapsulation substrate. In this case, the sealing portion can be formed of a sealant material and configured as a closed curve at the edge of the substrate 21. As another embodiment, the encapsulation component can include a thin-film encapsulation layer E. Hereinafter, for ease of explanation, a detailed description will focus on the case where the encapsulation component includes a thin-film encapsulation layer E.

[0140] The thin-film encapsulation layer E may include multiple inorganic layers or include both inorganic and organic layers.

[0141] The organic layer of the thin-film encapsulation layer E may include a polymer-based material. Polymer-based materials may include acrylic resins, epoxy resins, polyimides, and polyethylene, etc.

[0142] The inorganic layer of the thin-film encapsulation layer E may include one or more inorganic insulating materials selected from aluminum oxide, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride.

[0143] The outermost layer of the thin-film encapsulation layer E exposed to the outside can be formed of an inorganic layer to prevent moisture from penetrating into the organic light-emitting element (OLED) 28.

[0144] The thin-film encapsulation layer E may include at least one sandwich structure in which at least one organic layer is inserted between at least two inorganic layers. As another example, the thin-film encapsulation layer E may include at least one sandwich structure in which at least one inorganic layer is inserted between at least two organic layers. As yet another example, the thin-film encapsulation layer E may include both a sandwich structure in which at least one organic layer is inserted between at least two inorganic layers and a sandwich structure in which at least one inorganic layer is inserted between at least two organic layers.

[0145] The thin-film encapsulation layer E can be sequentially composed of a first inorganic layer, a first organic layer, and a second inorganic layer from the top of the organic light-emitting element (OLED) 28.

[0146] As another example, the thin-film encapsulation layer E may sequentially include a first inorganic layer, a first organic layer, a second inorganic layer, a second organic layer, and a third inorganic layer from the top of the organic light-emitting element (OLED) 28.

[0147] As another example, the thin-film encapsulation layer E may sequentially include a first inorganic layer, a first organic layer, a second inorganic layer, a second organic layer, a third inorganic layer, a third organic layer, and a fourth inorganic layer from the top of the organic light-emitting element (OLED) 28.

[0148] A halide metal layer comprising LiF can be further provided between the organic light-emitting element (OLED) 28 and the first inorganic layer. The halide metal layer can prevent damage to the organic light-emitting element (OLED) 28 when the first inorganic layer is formed by sputtering.

[0149] The area of ​​the first organic layer can be smaller than the area of ​​the second inorganic layer, and the area of ​​the second organic layer can also be smaller than the area of ​​the third inorganic layer.

[0150] As described above, when multiple inorganic layers are provided, the inorganic layers can be stacked in a way that they are in direct contact with each other in the edge region of the display device 20, so that the organic layers are not exposed to the outside.

[0151] Therefore, the display device 20 can achieve precise images.

[0152] As described above, the present invention has been illustrated with reference to the embodiments shown in the figures. However, these are merely illustrative, and those skilled in the art should understand that various modifications and variations of the embodiments can be made therefrom. Therefore, the true scope of protection of the present invention should be defined by the technical concept of the claims.
