Technical Field

[0001] This invention relates to a method for manufacturing a display device and an electronic device including the display device manufactured using this method. More specifically, it relates to a method for manufacturing a display device having a curved surface and an electronic device including the display device manufactured using this method. Background Technology

[0002] A display device is a device for displaying images to provide visual information to a user. A display device includes a display panel that displays images by emitting light, and various functional components arranged above and below the display panel. The display panel and functional components are assembled together after being aligned to precise positions to form a display device.

[0003] In recent years, in order to improve appearance, optical characteristics, and other aspects, the edges of display devices can be curved. Accordingly, when alignment marks are used to align the display panel and functional components, there is a problem that errors in the measurement of the position of the alignment marks placed on the curved surface can cause the display panel and functional components to not be aligned in the correct position. Summary of the Invention

[0004] One object of the present invention is to provide a method for manufacturing a display device that improves alignment accuracy.

[0006] However, the purpose of this invention is not limited to the above-mentioned purpose, and can be extended in various ways without departing from the spirit and scope of this invention.

[0007] To achieve the aforementioned objective of the present invention, a method for manufacturing a display device according to an embodiment of the present invention includes the following steps: providing a display panel including a first curved portion having a curved shape and a first flat portion adjacent to the first curved portion; providing a cover window including a second curved portion having a curved shape and a second flat portion adjacent to the second curved portion; extracting first position data about a first center of the display panel by photographing at least a portion of the display panel; extracting second position data about a second center of the cover window by photographing the second curved portion of the cover window; moving the display panel based on the first position data and the second position data so that the first center and the second center are aligned with each other in a plane; and combining the display panel and the cover window with each other.

[0010] In one embodiment, the method of manufacturing the display device may further include the following step: measuring the skew angle between the display panel and the cover window based on the first region of interest data and the second region of interest data.

[0011] In one embodiment, when the skew angle is 0°, after performing the step of measuring the skew angle between the display panel and the cover window, the step of moving the display panel to make the first center and the second center align with each other on the plane can be performed.

[0012] In one embodiment, the method of manufacturing the display device may further include a step of correcting the misalignment between the display panel and the cover window. After performing the step of measuring the misalignment angle between the display panel and the cover window, if the misalignment angle is not 0°, the step of correcting the misalignment between the display panel and the cover window may be performed.

[0013] In one embodiment, during the step of correcting the misalignment between the display panel and the cover window, the display panel can be rotated on a plane to correct the misalignment between the display panel and the cover window.

[0014] In one embodiment, the method of manufacturing the display device may further include the step of: re-measuring the skew angle between the display panel and the cover window by photographing the display panel and the cover window again. The step of re-measuring the skew angle between the display panel and the cover window can be performed after the step of correcting the skew between the display panel and the cover window.

[0015] In one embodiment, during the step of extracting the first position data about the first center of the display panel, the at least portion of the display panel being photographed may be located at the first curved portion of the display panel.

[0016] In one embodiment, the display panel may include four sides located at the outermost contour of the first curved portion and defined on a plane, and four corner portions defined by the meeting of two of the four sides. The first area of ​​interest may include multiple shooting areas that locally capture each of the four sides.

[0017] In one embodiment, the step of calculating the first position data from the first region of interest data may include the following steps: selecting two corners of the four corners of the display panel, connecting the two selected corners to each other to generate a first imaginary line on the plane that intersects each of the four sides; connecting the two unselected corners of the four corners of the display panel to each other to generate a second imaginary line on the plane that intersects the first imaginary line; and generating the coordinates of the first center where the first imaginary line and the second imaginary line intersect.

[0018] In one embodiment, the first area of ​​interest data may include data about the direction of extension of each of the four sides of the display panel.

[0019] In one embodiment, during the step of extracting the first position data about the first center of the display panel, the at least portion of the display panel being photographed may be located on the first planar portion of the display panel.

[0020] In one embodiment, the display panel may include a plurality of pixels and a plurality of wirings arranged on the first planar portion, and the step of setting the first area of ​​interest may include the following steps: illuminating the display panel; exploring a target wiring among the plurality of wirings within the first planar portion; and selecting a target pixel among the plurality of pixels that is adjacent to the target wiring.

[0021] In one embodiment, the first region of interest may be a region that includes the target pixel.

[0022] In one embodiment, the target wiring may be the outermost wiring located in the first planar portion of the plurality of wirings and adjacent to the first curved portion.

[0023] In one embodiment, the cover window may include four sides located at the outermost contour of the second curvature and defined on a plane, and four corners defined by the meeting of two of the four sides, and the second area of ​​interest may include multiple shooting areas that locally capture each of the four sides.

[0024] In one embodiment, the step of calculating the second location data from the second region of interest data may include the following steps: selecting two corners of the four corners of the overlay window and connecting the two selected corners to each other to generate a third imaginary line on the plane that intersects each of the four sides; connecting the two unselected corners of the four corners of the overlay window to each other to generate a fourth imaginary line on the plane that intersects the third imaginary line; and generating the coordinates of the second center where the third imaginary line intersects the fourth imaginary line.

[0025] In one embodiment, the second region of interest data may include data about the direction of extension of each of the four sides of the overlay window.

[0026] To achieve another objective of the present invention as described above, an electronic device according to an embodiment of this disclosure may include: a processor that outputs image data signals and inputs control signals; and a display device that processes the image data signals and the input control signals to output image information via a display screen. The display device may include: a display panel including a first curved portion having a curved shape and a first flat portion adjacent to the first curved portion; and a cover window including a second curved portion having a curved shape and a second flat portion adjacent to the second curved portion. The display device may be manufactured using the display device manufacturing method described above.

[0027] In the manufacturing method of the display device according to an embodiment of the present invention, a first center and a second center can be determined by photographing the curved portion of the display panel and the cover window, and the misalignment between the display panel and the cover window can be corrected. Furthermore, the display panel can be moved to align the first center of the display panel with the second center of the cover window before being joined to the cover window. This improves the accuracy of the joining between the display panel and the cover window. Moreover, no additional alignment key needs to be provided at the first curved portion of the display panel, thus reducing the manufacturing time and cost of the display device.

[0028] Furthermore, in an electronic device including the display device manufactured by the aforementioned method, the alignment marks may not be arranged in the curved areas of the display device included in the electronic device. This prevents misalignment that could occur when the display panel with the alignment marks arranged is joined to the cover window. Consequently, the durability of the electronic device can be improved.

[0029] However, the effects of the present invention are not limited to those described above, and can be extended in various ways without departing from the concept and scope of the present invention. Attached Figure Description

Figure 6 It is shown Figure 1 A flowchart illustrating an example of a method for manufacturing a display device. Figures 7 to 17 It is used for explanation Figure 6 A diagram illustrating the manufacturing method of a display device.

[0106] The following will omit or briefly describe and refer to the relevant information. Figures 1 to 4 The description is repeated on display device 100.

[0107] Reference Figure 1 and Figures 5 to 17 For manufacturing the display device 100, an alignment system 200, a guide film 400, a laminating part 500, a pushing part 600, and a fixture 700 can be used. The alignment system 200 may include a control part 210, an imaging part 220, an operation part 230, and an illumination part 240.

[0108] The control unit 210 can receive information about captured images from the imaging unit 220, or can transmit imaging command signals to the imaging unit 220 to cause the imaging unit 220 to start or stop imaging. The control unit 210 can transmit operation command signals to the operation unit 230 to cause the operation unit 230 to start or stop operation. The control unit 210 can transmit illumination command signals to the illumination unit 240 to cause the illumination unit 240 to start or stop operation.

[0109] Alignment system 200 may be included in the display device 100 as a component (e.g., Figure 2 The components (display panel 110, cover window 120, and cover panel 130) are aligned before being joined together. For example, alignment system 200 can be used to align display device components 300 in the manufacture of display device 100.

[0110] The display device assembly 300 may include a first assembly 310 and a second assembly 320. For the manufacture of the display device 100, the first assembly 310 and the second assembly 320 may be two different configurations combined with each other. For example, the first assembly 310 may be a display panel 110, and the second assembly 320 may be a cover window 120. However, the first assembly 310 and the second assembly 320 according to embodiments of the present invention are exemplary, and the first assembly 310 and the second assembly 320 are not necessarily limited thereto.

[0111] A method for manufacturing a display device according to an embodiment of the present invention (S1) may include the following steps: providing a display panel 110 and a cover window 120 (S10); extracting first position data about a first center C1 of the display panel 110 by photographing a first curved portion 110a of the display panel 110 (S20); extracting second position data about a second center C2 of the cover window 120 by photographing a second curved portion 120a of the cover window 120 (S30); measuring a skew angle between the display panel 110 and the cover window 120 based on first region of interest data and second region of interest data (S40); rotating the display panel 110 to correct the skew between the display panel 110 and the cover window 120 (S50); moving the display panel 110 based on the first position data and the second position data to make the first center C1 and the second center C2 coincide (S60); and combining the display panel 110 with the cover window 120 (S70).

[0112] The manufacturing method (S1) of the display device can be performed using an alignment system 200, a guide film 400, a laminating part 500, a pushing part 600, and a fixture 700.

[0113] The illumination unit 240 can illuminate the display panel 110 with illumination (e.g., light) in at least one of the following steps: extracting first position data about the first center C1 of the display panel 110 by photographing the first curved portion 110a of the display panel 110 (S20); extracting second position data about the second center C2 of the cover window 120 by photographing the second curved portion 120a of the cover window 120 (S30); measuring the skew angle between the display panel 110 and the cover window 120 based on the first and second area of ​​interest data (S40); rotating the display panel 110 to correct the skew between the display panel 110 and the cover window 120 (S50); moving the display panel 110 based on the first and second position data to align the first center C1 and the second center C2 (S60); and combining the display panel 110 with the cover window 120 (S70).

[0114] In step (S10) of providing the display panel 110 and the cover window 120, a flat pre-display panel 110p can be provided. The pre-display panel 110p can be the panel before it is bent. The bending of the pre-display panel 110p can be formed using the guide film 400 and the lamination portion 500. Specifically, the pre-display panel 110p and the guide film 400 can be bonded to each other. For example, the guide film 400 can be attached to the underside of the pre-display panel 110p. The pre-display panel 110p with the guide film 400 attached can be placed on the curved surface of the lamination portion 500 together with the guide film 400.

[0115] After the pre-display panel 110p is placed onto the laminating portion 500, the laminating portion 500 can be heated to deform the shape of its curved surface to correspond to the curved shape of the display panel 110. The guide film 400 can contact the curved surface and side surfaces of the laminating portion 500 and can be stretched by the pushing member 600. During the stretching of the guide film 400 by the pushing member 600, the pre-display panel 110p, coupled with the guide film 400, can be bent to correspond to the curved surface of the heated laminating portion 500.

[0116] Specifically, the edge portion of the prepared display panel 110p can also be stretched in the direction parallel to the first direction DR1 and the opposite direction to the third direction DR3 by a guide film 400 stretched in the direction parallel to the first direction DR1 and the opposite direction to the third direction DR3. Furthermore, the edge portion of the prepared display panel 110p can also be stretched in the direction parallel to the second direction DR2 and the opposite direction to the third direction DR3 by a guide film 400 stretched in the direction parallel to the second direction DR2 and the opposite direction to the third direction DR3. Accordingly, a display panel 110 including the first curved portion 110a can be formed.

[0117] The pre-bending cover window can be accommodated in a clamp 700. The clamp 700 may have a curved surface corresponding to the shape of the cover window 120, and the pre-bending cover window placed on the curved surface can be bent. Specifically, the pre-bending cover window can be heated or compressed to contact the curved surface of the clamp 700. Accordingly, a cover window 120 including a second bend 120a can be formed.

[0118] In other words, the step (S10) of providing the display panel 110 and the cover window 120 can be performed by means of the guide film 400, the laminating part 500, the pushing part 600 and the clamp 700.

[0119] In step (S20) of extracting the first position data about the first center C1 of the display panel 110 by photographing the first curved portion 110a of the display panel 110, the photographing unit 220 may photograph the first curved portion 110a of the display panel 110. In one embodiment, a first region of interest AOI1 may be designated within the first curved portion 110a of the display panel 110, and the photographing unit 220 may photograph the designated first region of interest AOI1. For example, the first region of interest AOI1 photographed by the photographing unit 220 may be a concept including multiple regions including the first side S1, the second side S2, the third side S3, and the fourth side S4 of the display panel 110.

[0120] The first side S1 of the display panel 110 may be the side of the display panel 110 facing the fourth direction DR4, and may be parallel to the fifth direction DR5. For example, the fourth direction DR4 may intersect the first direction DR1 and the second direction DR2 respectively on the plane defined by the first direction DR1 and the second direction DR2. Furthermore, the fifth direction DR5 may intersect the first direction DR1 and the second direction DR2 respectively on the plane defined by the first direction DR1 and the second direction DR2.

[0121] The second side S2 of the display panel 110 can be the side of the display panel 110 facing the opposite direction to the fourth direction DR4, and can be parallel to the fifth direction DR5. The third side S3 of the display panel 110 can be the side of the display panel 110 facing the opposite direction to the fifth direction DR5, and can be parallel to the fourth direction DR4. The fourth side S4 of the display panel 110 can be the side of the display panel 110 facing the fifth direction DR5, and can be parallel to the fourth direction DR4.

[0122] The terms S1, S2, S3, and S4 can refer to the curved side surfaces located on the upper surface of the display panel 110 when the display panel 110 is viewed on a plane.

[0123] The fourth direction DR4 and the fifth direction DR5 are used to describe the direction of the tilt between the display panel 110 and the cover window 120. When there is no tilt between the display panel 110 and the cover window 120, the fourth direction DR4 can be consistent with the first direction DR1, and the fifth direction DR5 can be consistent with the second direction DR2.

[0124] The display panel 110 may include a first corner CN1, a second corner CN2, a third corner CN3, and a fourth corner CN4. The first corner CN1, second corner CN2, third corner CN3, and fourth corner CN4 may be defined by a first side S1, a second side S2, a third side S3, and a fourth side S4. For example, the first corner CN1 may be defined by connecting the second side S2 and the third side S3 to each other in a plane. Similarly, the second corner CN2 may be defined by connecting the first side S1 and the fourth side S4 to each other in a plane. Likewise, the third corner CN3 may be defined by connecting the first side S1 and the third side S3 to each other in a plane. Finally, the fourth corner CN4 may be defined by connecting the second side S2 and the fourth side S4 to each other in a plane.

The fifteenth imaging region IA15 and the sixteenth imaging region IA16 may be regions used to extract directional data (e.g., data about the direction in which the eighth side S8 extends) with respect to the coverage window 120.

[0155] Specifically, a portion of the eighth side S8 is located within the fifteenth shooting area IA15, and the fifteenth shooting area IA15 may be adjacent to the eighth corner CN8 of the cover window 120, which is connected to both the sixth side S6 and the eighth side S8. Furthermore, a portion of the eighth side S8 may be located within the sixteenth shooting area IA16, and the sixteenth shooting area IA16 may be adjacent to the sixth corner CN6 of the cover window 120, which is connected to both the fifth side S5 and the eighth side S8.

[0156] The control unit 210 can extract the second region of interest (AOI) data from the second AOI2 captured by the imaging unit 220. The control unit 210 can calculate the position of the second center C2 of the overlay window 120 based on the second AOI data. Therefore, the control unit 210 can extract the second position data regarding the second center C2.

[0157] Specifically, control unit 210 can extract data from the ninth shooting area IA9. Control unit 210 can extract data from the tenth shooting area IA10. Control unit 210 can extract data from the eleventh shooting area IA11. Control unit 210 can extract data from the twelfth shooting area IA12. Control unit 210 can extract data from the thirteenth shooting area IA13. Control unit 210 can extract data from the fourteenth shooting area IA14. Control unit 210 can extract data from the fifteenth shooting area IA15. Control unit 210 can extract data from the sixteenth shooting area IA16. The second area of ​​interest data may include the data from the ninth shooting area to the sixteenth shooting area.

[0158] The control unit 210 can use the eleventh and thirteenth shooting area data to calculate the fifth corner position data of the fifth corner CN5 of the cover window 120, which is connected to the sixth side S6 and the seventh side S7, respectively. The control unit 210 can use the tenth and sixteenth shooting area data to calculate the sixth corner position data of the sixth corner CN6 of the cover window 120, which is connected to the fifth side S5 and the eighth side S8, respectively.

[0159] The control unit 210 can use the fifth corner position data and the sixth corner position data to generate a third imaginary line VL3 that connects the fifth corner CN5 and the sixth corner CN6 to each other.

[0160] The control unit 210 can use the ninth shooting area data and the fourteenth shooting area data to calculate the seventh corner position data of the seventh corner CN7 of the cover window 120, which is connected to the fifth side S5 and the seventh side S7, respectively. The control unit 210 can use the twelfth shooting area data and the fifteenth shooting area data to calculate the eighth corner position data of the eighth corner CN8 of the cover window 120, which is connected to the sixth side S6 and the eighth side S8, respectively.

[0161] The control unit 210 can use the seventh corner position data and the eighth corner position data to generate a fourth imaginary line VL4 that connects the seventh corner CN7 and the eighth corner CN8 to each other.

[0162] The control unit 210 can use the third imaginary line VL3 and the fourth imaginary line VL4 to calculate the position of the second center C2 of the coverage window 120. For example, the control unit 210 can calculate the position of the point where the third imaginary line VL3 and the fourth imaginary line VL4 intersect on the plane, and generate the second position data, which includes data about the coordinates of the second center C2, based on the calculated result.

[0163] However, the number of regions and the location of regions included in the second region of interest AOI2 according to the embodiments of the present invention are not limited to this. The second region of interest AOI2 may include a variety of numbers and locations of regions to calculate the location of the second center C2 of the coverage window 120.

[0164] In step (S40) of measuring the skew angle between the display panel 110 and the cover window 120 based on the first area of ​​interest data and the second area of ​​interest data, the control unit 210 can measure the degree of skewness between the display panel 110 and the cover window 120 on the plane based on the first area of ​​interest data and the second area of ​​interest data. The skewness may occur when the first side S1, the second side S2, the third side S3, and the fourth side S4 of the display panel 110 are not parallel to each other and the fifth side S5, the sixth side S6, the seventh side S7, and the eighth side S8 of the cover window 120 are not parallel to each other, or when the line that should be parallel to one side of the display panel 110 and the line of the cover window 120 corresponding to that side of the display panel 110 is tilted on the plane.

[0165] Specifically, the control unit 210 can use the first shooting area data, the second shooting area data, the ninth shooting area data, and the tenth shooting area data to determine whether there is a misalignment between the first side S1 of the display panel 110 and the fifth side S5 of the cover window 120.

[0166] Furthermore, the control unit 210 can use the third shooting area data, the fourth shooting area data, the eleventh shooting area data, and the twelfth shooting area data to determine whether there is a misalignment between the second side S2 of the display panel 110 and the sixth side S6 of the cover window 120.

[0167] Furthermore, the control unit 210 can use the fifth shooting area data, the sixth shooting area data, the thirteenth shooting area data, and the fourteenth shooting area data to determine whether there is a misalignment between the third side S3 of the display panel 110 and the seventh side S7 of the cover window 120.

[0168] Furthermore, the control unit 210 can use the seventh shooting area data, the eighth shooting area data, the fifteenth shooting area data, and the sixteenth shooting area data to determine whether there is a misalignment between the fourth side S4 of the display panel 110 and the eighth side S8 of the cover window 120.

[0169] Furthermore, the control unit 210 can use the first imaginary line VL1 and the third imaginary line VL3 to determine whether there is a misalignment between the display panel 110 and the cover window 120. The control unit 210 can also use the second imaginary line VL2 and the fourth imaginary line VL4 to determine whether there is a misalignment between the display panel 110 and the cover window 120.

[0170] Therefore, the control unit 210 can measure the skew angle between the display panel 110 and the cover window 120. If there is no skew between the display panel 110 and the cover window 120, the skew angle can be 0°.

[0171] In one embodiment, if the control unit 210 determines that there is no misalignment between the display panel 110 and the cover window 120, it may perform a step of moving the display panel 110 based on the first position data and the second position data to make the first center C1 and the second center C2 align with each other (S60), instead of performing a step of rotating the display panel 110 to correct the misalignment between the display panel 110 and the cover window 120 (S50).

[0172] In one embodiment, if the control unit 210 determines that there is a misalignment between the display panel 110 and the cover window 120, a step (S50) can be performed to rotate the display panel 110 to correct the misalignment between the display panel 110 and the cover window 120.

[0173] In the step (S50) of correcting the misalignment between the display panel 110 and the cover window 120 by rotating the display panel 110, if the control unit 210 determines that a misalignment has occurred between the display panel 110 and the cover window 120, the operation unit 230 can rotate the display panel 110 so that the first side S1, the second side S2, the third side S3, and the fourth side S4 of the display panel 110 are parallel to the fifth side S5, the sixth side S6, the seventh side S7, and the eighth side S8 of the cover window 120. For example, the operation unit 230 can rotate the laminating unit 500 about the third direction DR3 as the rotation axis. In addition, the operation unit 230 can be coupled with the laminating unit 500 to rotate the laminating unit 500.

[0174] After the display panel 110 is rotated, the imaging unit 220 can re-image each of the display panel 110 and the cover window 120, and the control unit 210 can re-measure whether there is any misalignment between the display panel 110 and the cover window 120. If the control unit 210 re-measures the misalignment angle between the display panel 110 and the cover window 120 and determines that the misalignment angle is not 0°, the control unit 210 can transmit the operation command signal to cause the operation unit 230 to rotate the display panel 110 again. Thus, the operation unit 230 can rotate the display panel 110 again.

[0175] In other words, the control unit 210, the imaging unit 220, and the operation unit 230 can repeatedly perform the operations of re-imaging the display panel 110 and the cover window 120, re-measuring whether there is any skew between the display panel 110 and the cover window 120, and re-rotating the display panel 110 so that the skew angle between the display panel 110 and the cover window 120 becomes 0°.

[0176] As the operation unit 230 rotates the display panel 110, the skew angle between the display panel 110 and the cover window 120 becomes 0°, and the skew between the display panel 110 and the cover window 120 can be corrected.

[0177] In the step (S60) of moving the display panel 110 based on the first position data and the second position data to make the first center C1 and the second center C2 coincide, the control unit 210 can compare the coordinates of the first center C1 included in the first position data and the coordinates of the second center C2 included in the second position data.

[0178] If the control unit 210 determines that the coordinates of the first center C1 and the second center C2 are different, the control unit 210 may transmit the operation command signal to the operation unit 230 to make the first center C1 and the second center C2 align with each other on the plane. Thus, the operation unit 230 may move the display panel 110 in a direction parallel to the plane defined by the first direction DR1 and the second direction DR2 to make the first center C1 and the second center C2 align with each other.

[0179] If the control unit 210 determines that the coordinates of the first center C1 are the same as the coordinates of the second center C2, the step of combining the display panel 110 with the overlay window 120 can be performed (S70).

[0180] In the step (S70) of combining the display panel 110 with the cover window 120, with the first center C1 and the second center C2 aligned with each other on the plane, the operation unit 230 can move the clamp 700 combined with the cover window 120. For example, the operation unit 230 can combine with the clamp 700, thereby moving the clamp 700 in the vertical direction (e.g., the third direction DR3 or the opposite direction of the third direction DR3).

[0181] The cover window 120, engaged with the clamp 700, can contact the display panel 110. Before the display panel 110 contacts the cover window 120, an adhesive layer can be applied to a surface of the display panel 110 facing the cover window 120. Thus, the display panel 110 and the cover window 120 can be joined. However, the joining process of the display panel 110 and the cover window 120 according to an embodiment of the present invention is exemplary and not necessarily limited thereto. For example, the adhesive layer can also be applied to a surface of the cover window 120 facing the display panel 110.

[0182] After the display panel 110 and the cover window 120 are joined, the display panel 110 and the cover window 120, which are joined with the clamp 700, can be moved toward the cover panel 130 including the third bend 130a, and the cover panel 130 including the third bend 130a can be moved toward the clamp 700, thereby joining the display panel 110 and the cover panel 130 together. After the display panel 110, the cover window 120, and the cover panel 130 are joined together, the clamp 700 can be removed from the cover window 120. Thus, it is possible to manufacture... Figure 1 The display device 100.

[0183] As described above, in the manufacturing method (S1) of the display device, the first center C1 and the second center C2 can be determined by photographing the curved portions (e.g., the first curved portion 110a and the second curved portion 120a) of the display panel 110 and the cover window 120, and the misalignment between the display panel 110 and the cover window 120 can be corrected. Furthermore, after moving the display panel 110 to align the first center C1 of the display panel 110 and the second center C2 of the cover window 120, the display panel 110 can be joined to the cover window 120. This improves the accuracy of the joining between the display panel 110 and the cover window 120. Moreover, since no additional alignment marks need to be arranged on the first curved portion 110a of the display panel 110, the manufacturing time and cost of the display device 100 can be reduced.

[0184] Furthermore, in the display device 100 manufactured by the display device manufacturing method (S1), alignment marks may not be arranged in the curved region CA of the display device 100. This prevents misalignment that could occur when the display panel 110 with the alignment marks is joined to the cover window 120. This improves the durability of the display device 100.

[0185] Figure 18 It is shown Figure 1 A flowchart of another example of a method for manufacturing a display device. Figure 19 It is shown Figure 18 A flowchart of the steps for extracting first position data about the first center of the display panel by photographing the first flat part of the display panel. Figures 20 to 22 It is shown Figure 18 A flowchart of another example of a method for manufacturing a display device.

[0186] For example, Figure 21 This is a diagram illustrating an example of the process of exploring the target wiring TLN in the step (S20A) of extracting the first position data about the first center C1 of the display panel 110 by photographing the first planar portion 110b of the display panel 110.

[0187] For example, Figure 22 This is a diagram illustrating another example of the process of exploring the target wiring TLN in the step (S20A) of extracting the first position data about the first center C1 of the display panel 110 by photographing the first planar portion 110b of the display panel 110.

[0188] Reference Figure 18 and Figure 19The manufacturing method (S1A) of the described display device, except for the step (S20A) of extracting the first position data about the first center C1 of the display panel 110 by photographing the first planar portion 110b of the display panel 110, can be compared with the reference. Figure 6 The manufacturing method (S1) of the described display device is substantially the same as or similar to that described below. Hereinafter, descriptions will be omitted or briefly referenced. Figures 6 to 17 The description contains repetitive content.

[0189] Reference Figures 18 to 22 A method for manufacturing a display device according to an embodiment of the present invention (S1A) may include the following steps: providing a display panel 110 and a cover window 120 (S10); extracting first position data about a first center C1 of the display panel 110 by photographing a first planar portion 110b of the display panel 110 (S20A); extracting second position data about a second center C2 of the cover window 120 by photographing a second curved portion 120a of the cover window 120 (S30); measuring the skew angle between the display panel 110 and the cover window 120 based on first region of interest data and second region of interest data (S40); rotating the display panel 110 to correct the skew between the display panel 110 and the cover window 120 (S50); moving the display panel 110 based on the first position data and the second position data to make the first center C1 and the second center C2 coincide (S60); and combining the display panel 110 with the cover window 120 (S70).

[0190] The step (S20A) of extracting the first position data about the first center C1 of the display panel 110 by photographing the first planar portion 110b of the display panel 110 may include the following steps: illuminating the display panel 110 (S210); exploring the target wiring TLN adjacent to the first curved portion 110a within the first planar portion 110b (S220); setting a first region of interest AOI1a by selecting a target pixel TPX adjacent to the target wiring TLN (S230); generating hypothetical coordinate data based on the first region of interest data (S240); and calculating the first position data about the first center C1 of the display panel 110 based on the hypothetical coordinate data (S250).

[0191] Further reference Figure 5In the step (S210) of illuminating the display panel 110 with illumination (e.g., light), the illumination unit 240 can be used to illuminate the display panel 110. For example, the illumination unit 240 can be arranged below the display panel 110, and the light emitted from the illumination unit 240 can illuminate the entire first curved portion 110a and the first flat portion 110b of the display panel 110. As another example, the illumination unit 240 can be arranged below the display panel 110, and the light emitted from the illumination unit 240 can also illuminate only a portion of the display panel 110 required to perform the steps of the manufacturing method (S1A). However, the position of the illumination unit 240 and the area of ​​the display panel 110 illuminated by the light according to embodiments of the present invention are not necessarily limited to these.

[0192] The step of illuminating the display panel 110 (S210) can be continuously performed during at least one of the following steps: exploring a target wiring TLN adjacent to the first curved portion 110a within the first planar portion 110b (S220); setting a first region of interest AOI1a by selecting a target pixel TPX adjacent to the target wiring TLN (S230); generating hypothetical coordinate data based on the first region of interest data (S240); and calculating the first position data about the first center C1 of the display panel 110 based on the hypothetical coordinate data (S250).

[0193] In step (S220) of exploring the target wiring TLN adjacent to the first curved portion 110a within the first planar portion 110b, the imaging unit 220 can capture an image of the display panel 110, and the control unit 210 can explore at least one of the multiple wirings arranged within the first planar portion 110b based on the captured image of the display panel 110. For example, during the period when the illumination unit 240 illuminates the display panel 110, the control unit 210 can determine the target wiring TLN among the wirings included in the illuminated display panel 110 that is arranged at the position required to generate the first position data.

[0194] In step (S230) of setting the first region of interest AOI1a by selecting a target pixel TPX adjacent to the target wiring TLN, the control unit 210 can select the target pixel TPX adjacent to the target wiring TLN after exploring and selecting the target wiring TLN. After setting the target pixel TPX, the control unit 210 can set the first region of interest AOI1a including the target pixel TPX and the area surrounding the target pixel TPX of the display panel 110.

[0195] After setting the first area of ​​interest AOI1a, the imaging unit 220 can capture images of the set first area of ​​interest AOI1a. The first area of ​​interest AOI1a may include a first imaging area IA1a, a second imaging area IA2a, a third imaging area IA3a, and a fourth imaging area IA4a. In one embodiment, the first imaging area IA1a, the second imaging area IA2a, the third imaging area IA3a, and the fourth imaging area IA4a may be spaced apart from each other on a plane.

[0196] In one embodiment, in the step (S220) of exploring the target wiring TLN adjacent to the first curved portion 110a within the first planar portion 110b, the control unit 210 can identify the first wiring LN1, the second wiring LN2, the third wiring LN3 and the fourth wiring LN4 from the captured image of a portion of the display panel 110 corresponding to the first shooting area IA1a.

[0197] However, although the step of exploring the target wiring TLN adjacent to the first curved portion 110a within the first flat portion 110b (S220) is performed before generating the first shooting area IA1a, for convenience, the process of selecting the target wiring TLN and the target pixel TPX from a portion of the display panel 110 located in the first shooting area IA1a will be described.

[0198] After the control unit 210 identifies the first wiring LN1, the second wiring LN2, the third wiring LN3, and the fourth wiring LN4, the control unit 210 can select the fourth wiring LN4, which is the outermost one among the first wiring LN1, the second wiring LN2, the third wiring LN3, and the fourth wiring LN4, as the target wiring TLN. In other words, the target wiring TLN can be the outermost wiring among the plurality of wirings arranged in the first planar portion 110b. For example, the target wiring TLN can be the wiring closest to the first bend portion 110a among the plurality of wirings.

[0199] After the control unit 210 selects the target wiring TLN, the control unit 210 can select the seventh pixel PX7, which is closest to the target wiring TLN and the first bending portion 110a among the first pixel PX1, second pixel PX2, third pixel PX3, fourth pixel PX4, fifth pixel PX5, sixth pixel PX6 and seventh pixel PX7, as the target pixel TPX.

[0200] Further reference Figure 1 and Figure 4In another embodiment, when the display device 100 is a stretchable display device 100, the display device 100 may include a first region A1 and a second region A2. For example, the second region A2 can be expanded according to the user's stretching. The control unit 210 can select a wiring that spans the first region A1 and the second region A2 and is not covered by the thin-film encapsulation layer TFE and the touch insulating layer TIL as a target wiring TLN. However, the process by which the control unit 210 selects the target wiring TLN according to an embodiment of the present invention is exemplary and is not limited thereto.

[0201] Furthermore, although it has been explained that the control unit 210 uses the target wiring TLN and the target pixel TPX to extract the first region of interest data, according to an embodiment of the present invention... Figure 6 and Figure 18 The manufacturing method (S1, S1A) is not limited to this, and the first region of interest data can also be extracted using the configuration included in the display panel 110 other than the target wiring TLN and the target pixel TPX.

[0202] In the step (S240) of generating hypothetical coordinate data based on the first region of interest data, the control unit 210 uses a first shooting region IA1a, a second shooting region IA2a, a third shooting region IA3a, and a fourth shooting region IA4a, which respectively include the target pixel TPX, to generate hypothetical coordinate data for each of the first shooting region IA1a, the second shooting region IA2a, the third shooting region IA3a, and the fourth shooting region IA4a. However, the number, position, etc. of the shooting regions including the target pixel TPX according to the embodiments of the present invention are exemplary and are not necessarily limited thereto.

[0203] In step (S250) of calculating the first position data about the first center C1 of the display panel 110 based on the hypothetical coordinate data, the control unit 210 may generate a first hypothetical line VL1a and a second hypothetical line VL2a based on the hypothetical coordinate data. The control unit 210 may use the first hypothetical line VL1a and the second hypothetical line VL2a to calculate the first position data about the first center C1.

[0204] As described above, in the manufacturing method (S1A) of the display device, the first center C1 and the second center C2 are determined by photographing the curved portions (e.g., the first curved portion 110a and the second curved portion 120a) of the display panel 110 and the cover window 120, and the misalignment between the display panel 110 and the cover window 120 is corrected. Furthermore, the display panel 110 can be moved to align the first center C1 of the display panel 110 with the second center C2 of the cover window 120 before being joined to the cover window 120. This improves the accuracy of the joining between the display panel 110 and the cover window 120. Since no additional alignment marks need to be provided on the first curved portion 110a of the display panel 110, the manufacturing time and cost of the display device 100 can be reduced.

[0205] In addition to the curved portion 110a of the display panel 110, the first area of ​​interest data for determining the first center C1 can be extracted using the components within the display panel 110 (e.g., pixels, wiring, etc.). Therefore, even if the curved portion 110a of the display panel 110 cannot be measured, the combination between the display panel 110 and the cover window 120 can be easily performed using the manufacturing method (S1A) of the display device.

[0206] Furthermore, in the display device 100 manufactured by the display device manufacturing method (S1A), alignment marks may not be provided in the curved region CA of the display device 100. This prevents misalignment that could occur when the display panel 110 with the alignment marks is joined to the cover window 120. This improves the durability of the display device 100.

[0207] The display device according to the embodiment (e.g., Figure 1 The display device 100 can be applied to a variety of electronic devices. According to one embodiment, an electronic device may include the aforementioned display device (e.g., Figure 1 The display device 100 may also include modules or devices with additional functions in addition to the display device.

[0208] Figure 23 This is a block diagram of an electronic device according to one embodiment.

[0209] Reference Figure 23 According to one embodiment, the electronic device 10 may include a display module 11, a processor 12, a memory 13, and a power module 14.

[0210] The processor 12 may include at least one of a central processing unit (CPU), an application processor (AP), a graphics processing unit (GPU), a communication processor (CP), an image signal processor (ISP), and a controller.

[0211] The memory 13 may store data information required for the operation of the processor 12 or the display module 11. If the processor 12 executes the application stored in the memory 13, the image data signal and / or input control signal may be transmitted to the display module 11, and the display module 11 may process the received signal and output image information through the display screen.

[0212] The power module 14 may include a power supply module such as a power adapter or battery device, and a power conversion module that converts the power supplied by the power supply module to generate the power required for the operation of the electronic device 10.

[0213] At least one of the components of the electronic device 10 described above may be included in the display device according to the above embodiments (e.g., Figure 1 The display device 100 is included within the display device. Furthermore, functionally, a portion of an individual module included in a single module may be included within the display device, while another portion may be provided separately from the display device. For example, the display device may include a display module 11, while the processor 12, memory 13, and power module 14 may be provided in the form of other devices within the electronic device 10 that are not the display device.

[0214] In one embodiment, the electronic device 10 may include the use of Figure 6 or Figure 18 The display device is manufactured using the manufacturing method described above. In one embodiment, the electronic device 10 may include the display device, which includes: a processor 12 that outputs the image data signal and the input control signal to the display device; and a display module 11 that is driven (or operated) by the image data signal and the input control signal.

[0215] In one embodiment, the electronic device 10 may include a reference Figure 6 The manufacturing method described (S1) or reference Figure 18 The display device is manufactured by at least one of the manufacturing methods (S1A) described herein.

[0216] Figure 24This is a schematic diagram of an electronic device according to various embodiments.

[0217] Reference Figure 24 The display device according to the embodiment (e.g., Figure 1 Various electronic devices (e.g., display device 100) Figure 23 The electronic device 10) may include not only electronic devices for displaying images such as smartphones 10_1a, tablet PCs 10_1b, laptop computers 10_1c, televisions (TVs) 10_1d, and desktop monitors 10_1e, but also wearable electronic devices including display modules such as smart glasses 10_2a, head-mounted displays 10_2b, and smartwatches 10_2c, as well as vehicle electronic devices 10_3 including display modules such as car dashboards, center consoles, central information displays (CID) arranged on the dashboard, and room mirror displays.

[0218] As described above, in the electronic device 10 including the display device manufactured using the aforementioned display device manufacturing method, the alignment marks may not be arranged in the curved region of the display device included in the electronic device 10. This prevents the alignment marks from being arranged on the display panel (e.g., where they are present). Figure 3 The display panel 110) and the cover window (e.g., Figure 3 The misalignment that occurs when the cover window 120 is combined with the electronic device 10 can be improved.

[0219] Furthermore, the electronic device 10 may include a display device comprising a display module 11, a processor 12 for running the display module 11, a memory 13, and a power supply module 14.
