Technical Field
[0001] This invention relates to a display device and a method for manufacturing the same. Background Technology
[0002] The display device includes a substrate, a display panel, and a film. For example, the film may be a flexible printed circuit board (FPCB). The display panel can receive signals and / or voltages from a driving portion disposed on the film.

Specifically, pads (e.g., data pads) formed on the substrate contact pads (e.g., film pads) formed on the lower part of the film, and the data pads are connected to the display panel.

Detailed Implementation
[0044] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same constituent elements in the drawings, and repeated descriptions of the same constituent elements are omitted.
[0045] Figure 1 and Figure 2 This is a plan view illustrating a display device according to an embodiment of the present invention.
[0046] Reference Figure 1 and Figure 2An embodiment of the present invention relates to a display device 10, which may include a substrate SUB, a display panel PNL, a film FLM, a plurality of data pads DP, a plurality of film pads FP, a panel alignment mark PAL, a film alignment mark FAL, a panel magnetic portion PMP, and a film magnetic portion FMP. The film FLM may be disposed on the substrate SUB using the panel alignment mark PAL, the film alignment mark FAL, the panel magnetic portion PMP, and the film magnetic portion FMP.
[0047] The substrate SUB may include a display area DA and a non-display area NDA. In one embodiment, the display area DA may have a quadrilateral shape, and the non-display area NDA may be adjacent to the display area DA. For example, the non-display area NDA may be configured to surround the display area DA. In one embodiment, such as... Figure 1 and Figure 2 As shown, the non-display area NDA can have a quadrilateral shape with a constant width. In other embodiments, the non-display area NDA can have a shape that gradually narrows in width towards the lower end of the substrate SUB in a plane.
[0048] In one embodiment, the data pad DP, the panel alignment mark PAL, and the panel magnetic portion PMP can be disposed on the substrate SUB and overlap with the non-display area NDA. For example, as Figure 1 and Figure 2 As shown, two panel alignment marks (PALs) and two panel magnetic portions (PMPs) can be formed. The panel magnetic portions (PMPs) can be configured symmetrically about the data pad (DP). The panel alignment marks (PALs) can be positioned between the panel magnetic portions (PMPs) and the data pad (DP). Furthermore, a TEG pattern for monitoring manufacturing processes can be formed in the non-display area (NDA) on the substrate (SUB). However, the positions of the data pad (DP), the panel alignment marks (PALs), and the panel magnetic portions (PMPs) are not limited to these.
[0049] The display panel PNL can be disposed on the substrate SUB and overlap with the display area DA. The display panel PNL can receive signals and / or voltages and display images.
[0050] In one embodiment, the display panel PNL can receive data voltage from the film FLM via the data pads DP. For example, a plurality of data pads DP can extend in a first direction D1 and be spaced apart from each other in a second direction D2 intersecting the first direction D1. Thus, a first spacing P1 in the second direction D2 can be defined between each of the data pads DP. Furthermore, each data pad DP can have a first width W1 in the second direction D2.
[0051] Furthermore, the display panel PNL can also receive a drive voltage (e.g., a high power supply voltage) through a drive power pad adjacent to the data pad DP, and can also receive a common voltage (e.g., a low power supply voltage) through a common power pad adjacent to the data pad DP.
[0052] like Figure 2 As shown, the film FLM can be disposed on the substrate SUB and overlaps with the non-display area NDA. A driving unit can be disposed on the film FLM. For example, a data driving unit that generates the data voltage can be disposed on the film FLM. Furthermore, a power management unit (e.g., a power management circuit) that generates the driving voltage and / or the common voltage can also be disposed on the film FLM.
[0053] In one embodiment, the film pad FP, the film alignment mark FAL, and the film magnetic part FMP can be disposed below the film FLM and overlap with the non-display area NDA.
[0054] In one embodiment, the film pad FP can be formed to correspond to the data pad DP. For example, the film pad FP can be formed to have the same spacing as the data pad DP (i.e., the first spacing P1).
[0055] like Figure 1 and Figure 2 As shown, the film FLM can be aligned so that the film pad FP and the data pad DP overlap. To precisely align the film FLM, the panel magnetic portion PMP, the film magnetic portion FMP, the panel alignment mark PAL, and the film alignment mark FAL can be used.
[0056] For example, the degree to which the panel alignment mark PAL and the film alignment mark FAL overlap can be photographed to confirm whether the film FLM is properly aligned to the substrate SUB.
[0057] Figure 3 It is used for explanation Figure 2 A cross-sectional view of the display device.
[0058] Reference Figure 2 and Figure 3 The display device 10 may include the substrate SUB, the display panel PNL, the sealing component SEAL, the encapsulation substrate ENC, the sensing layer SL, the window WIN, the panel magnetic part PMP, the film FLM, and the film magnetic part FMP.
[0059] The substrate SUB may include transparent or opaque materials. For example, the substrate SUB may include glass, quartz, plastic, etc. When the substrate SUB includes glass, the display device 10 may be a rigid display device. When the substrate SUB includes plastic, the display device 10 may be a flexible display device. When the display device 10 is a flexible display device, the film FLM may also be disposed at the bottom of the substrate SUB.
[0060] The display panel PNL can be disposed on the substrate SUB. For the display panel PNL, refer to... Figure 13 To illustrate.
[0061] The encapsulation substrate ENC may be opposite the substrate SUB and disposed on the display panel PNL. In one embodiment, the encapsulation substrate ENC may have substantially the same shape as the substrate SUB and may comprise substantially the same material as the substrate SUB. In other embodiments, the encapsulation substrate ENC may have a different shape and / or a different area than the substrate SUB. Furthermore, the encapsulation substrate ENC may also comprise a different material than the substrate SUB.
[0062] In one embodiment, the sealing element SEAL may be disposed between the substrate SUB and the encapsulation substrate ENC. The sealing element SEAL may be formed to surround the display panel PNL in a planar manner. The sealing element SEAL protects the display panel PNL from foreign matter and / or moisture. In other embodiments, the sealing element SEAL may be omitted. In this case, an encapsulation layer may be added to the display panel PNL to protect it.
[0063] The sensing layer SL can be disposed on the packaging substrate ENC. The sensing layer SL can sense the user's proximity and / or touch. For example, the sensing layer SL may include multiple sensing electrodes, and a capacitor may be formed between each of the sensing electrodes. The sensing layer SL can use the capacitor to sense the proximity and / or touch.
[0064] The window WIN can be configured on the sensing layer SL. The window WIN may include glass and / or plastic. The window WIN can protect the sensing layer SL, the display panel PNL, the film FLM, etc.
[0065] The film FLM can be disposed on the substrate SUB. Thus, the film magnetic portion FMP can contact the panel magnetic portion PMP. Furthermore, the film pad FP formed on the film FLM can contact the data pad DP.

Figure 7 It is used for explanation Figure 2 A cross-sectional view of the first panel magnetic pattern and the first film magnetic pattern included in the display device. For example, Figure 7 It can be along Figure 2 A sectional view taken from line II′.
[0067] Reference Figure 1 and Figure 4 The panel magnetic part PMP may include a plurality of first panel magnetic patterns 110, a plurality of second panel magnetic patterns 120, a plurality of third panel magnetic patterns 130, a plurality of fourth panel magnetic patterns 140, a first panel magnetic input part 310, a second panel magnetic input part 320, and a conductive part 510.
[0068] In one embodiment, the panel magnetic portion PMP can be formed together with the data pad DP. In other words, the panel magnetic portion PMP can include the same material as the data pad DP. For example, the panel magnetic portion PMP can include metals, alloys, conductive metal oxides, transparent conductive materials, etc. The panel magnetic portion PMP can include silver (Ag), silver-containing alloys, molybdenum (Mo), molybdenum-containing alloys, aluminum (Al), aluminum-containing alloys, aluminum nitride (AlN), tungsten (W), tungsten nitride (WN), copper (Cu), nickel (Ni), chromium (Cr), chromium nitride (CrN), titanium (Ti), tantalum (Ta), platinum (Pt), scandium (Sc), indium tin oxide (ITO), indium zinc oxide (IZO), etc.
[0069] A plurality of first panel magnetic patterns 110 may be formed on the substrate SUB and overlap with the non-display area NDA. The plurality of first panel magnetic patterns 110 may extend in the first direction D1 and be spaced apart from each other in the second direction D2. The first panel magnetic patterns 110 may be connected to the first panel magnetic input portion 310.
[0070] In one embodiment, each of the first panel magnetic patterns 110 may have a second width W2 in the second direction D2. The second width W2 may be smaller than the first width W1 of each of the data pads DP. However, the relationship between the first width W1 and the second width W2 is not limited thereto.
[0071] A plurality of second panel magnetic patterns 120 may be formed on the substrate SUB and overlap with the non-display area NDA. The plurality of second panel magnetic patterns 120 may extend in the first direction D1 and be spaced apart from each other in the second direction D2. The second panel magnetic patterns 120 may be connected to the second panel magnetic input portion 320.
[0072] In one embodiment, the second panel magnetic pattern 120 can be disposed between each of the first panel magnetic patterns 110. Thus, a second spacing P2 in the second direction D2 can be defined between adjacent first panel magnetic patterns 110 and second panel magnetic patterns 120. The second spacing P2 can be smaller than the first spacing P1. However, the relationship between the first spacing P1 and the second spacing P2 is not limited thereto.
[0073] The first panel magnetic pattern 110 and the second panel magnetic pattern 120 can improve the alignment precision of the film FLM in the second direction D2.
[0074] In one embodiment, the first panel magnetic pattern 110 and the second panel magnetic pattern 120 can be arranged irregularly. For example, the order in which the first panel magnetic pattern 110 and the second panel magnetic pattern 120 are arranged can be set as needed. For example, as... Figure 4 As shown, when each of the first panel magnetic patterns 110 is referred to as "a" and each of the second panel magnetic patterns 120 is referred to as "b", the first panel magnetic patterns 110 and the second panel magnetic patterns 120 can be arranged in the order a, b, a, b, a, b, b, a, b, a.
[0075] Multiple third panel magnetic patterns 130 may be arranged on the substrate SUB and overlap with the non-display area NDA. The multiple third panel magnetic patterns 130 may extend in the second direction D2 and be spaced apart from each other in the first direction D1. The third panel magnetic patterns 130 may be connected to the first panel magnetic input portion 310.
[0076] Multiple fourth panel magnetic patterns 140 may be formed on the substrate SUB and overlap with the non-display area NDA. The multiple fourth panel magnetic patterns 140 may extend in the second direction D2 and be spaced apart from each other in the first direction D1. The fourth panel magnetic patterns 140 may be connected to the second panel magnetic input portion 320.
[0077] In one embodiment, the fourth panel magnetic pattern 140 may be arranged between each of the third panel magnetic patterns 130. Furthermore, the third panel magnetic patterns 130 and the fourth panel magnetic pattern 140 may be arranged irregularly. The third panel magnetic patterns 130 and the fourth panel magnetic pattern 140 can improve the alignment precision of the film FLM in the first direction D1.
[0078] The first panel magnetic input portion 310 can be connected to the first panel magnetic pattern 110 and the third panel magnetic pattern 130. The first panel magnetic input portion 310 can input a first magnetism into the first panel magnetic pattern 110 and the third panel magnetic pattern 130. For example, the first panel magnetic input portion 310 can be a pad with a certain area. By bringing the first panel magnetic input portion 310 into contact with a magnetic material, the first panel magnetic input portion 310 can input the first magnetism into the first panel magnetic pattern 110 and the third panel magnetic pattern 130. Thus, the first panel magnetic pattern 110 and the third panel magnetic pattern 130 can possess a first magnetism (e.g., a south pole).
[0079] The second panel magnetic input section 320 can be connected to the second panel magnetic pattern 120 and the fourth panel magnetic pattern 140. The second panel magnetic input section 320 can input a second magnetism to the second panel magnetic pattern 120 and the fourth panel magnetic pattern 140. Thus, the second panel magnetic pattern 120 and the fourth panel magnetic pattern 140 can have a second magnetism (e.g., an N pole).
[0080] In one embodiment, the first panel magnetic input portion 310 and the second panel magnetic input portion 320 may be disposed on the substrate SUB and overlap with the non-display area NDA. In other embodiments, the first panel magnetic input portion 310 and the second panel magnetic input portion 320 may be formed on a mother substrate used in the manufacturing process of the display device 10. In this case, the first panel magnetic input portion 310 and the second panel magnetic input portion 320 may be removed by a cutting process of the mother substrate.
[0081] The conductive portion 510 can be disposed on the substrate SUB and overlap with the non-display area NDA. The conductive portion 510 can be a conductive pattern formed integrally. In one embodiment, the conductive portion 510 may include a first end portion 511 extending in the first direction D1 and a second end portion 512 extending in the first direction D1. The first end portion 511 and the second end portion 512 are spaced apart by a third distance P3. In one embodiment, the third distance P3 may be substantially the same as the second distance P2. However, the size relationship of the first distance P1, the second distance P2 and the third distance P3 is not limited to the above situation and can be appropriately set as needed.
[0082] Reference Figure 1 and Figure 5 The film magnetic part FMP may include a plurality of first film magnetic patterns 210, a plurality of second film magnetic patterns 220, a plurality of third film magnetic patterns 230, a plurality of fourth film magnetic patterns 240, a first film magnetic input part 410, a second film magnetic input part 410, a check current input part 520, and a check current output part 530. Except for the check current input part 520 and the check current output part 530, the film magnetic part FMP may have a shape substantially the same as the panel magnetic part PMP.
[0083] In one embodiment, the magnetic membrane portion (FMP) may be formed together with the membrane pad (FP). In other words, the magnetic membrane portion (FMP) may include the same material as the membrane pad (FP). For example, the magnetic membrane portion (FMP) may include metals, alloys, conductive metal oxides, transparent conductive materials, etc.
[0084] Multiple first film magnetic patterns 210 may be formed on the lower part of the film FLM and overlap with the non-display area NDA. The first film magnetic patterns 210 may be formed to correspond to the first panel magnetic pattern 110. For example, multiple first film magnetic patterns 210 may extend in the first direction D1 and be spaced apart from each other in the second direction D2. The first film magnetic patterns 210 may be connected to the first film magnetic input section 410.
[0085] Multiple second film magnetic patterns 220 may be formed on the lower part of the film FLM and overlap with the non-display area NDA. The second film magnetic patterns 220 may be formed to correspond to the second panel magnetic pattern 120. For example, multiple second film magnetic patterns 220 may extend in the first direction D1 and be spaced apart from each other in the second direction D2. The second film magnetic patterns 220 may be connected to the second film magnetic input section 420.
[0086] In one embodiment, the second film magnetic pattern 220 may be disposed between each of the first film magnetic patterns 210. The first film magnetic pattern 210 and the second film magnetic pattern 220 may improve the alignment precision of the film FLM in the second direction D2.
[0087] The order in which the first film magnetic pattern 210 and the second film magnetic pattern 220 are arranged can be set as needed. For example, as Figure 5 As shown, when each of the first film magnetic patterns 210 is referred to as "c" and each of the second film magnetic patterns 220 is referred to as "d", the first film magnetic patterns 210 and the second film magnetic patterns 220 can be arranged in the order of c, d, c, d, c, d, c, d, c.
[0088] Multiple third-film magnetic patterns 230 may be formed on the lower part of the film FLM and overlap with the non-display area NDA. The third-film magnetic patterns 230 may be formed to correspond to the third panel magnetic pattern 130. For example, multiple third-film magnetic patterns 230 may extend in the second direction D2 and be spaced apart from each other in the first direction D1. The third-film magnetic patterns 230 may be connected to the first film magnetic input section 410.
[0089] Multiple fourth film magnetic patterns 240 may be formed on the lower part of the film FLM and overlap with the non-display area NDA. The fourth film magnetic patterns 240 may be formed to correspond to the fourth panel magnetic pattern 140. For example, multiple fourth film magnetic patterns 240 may extend in the second direction D2 and be spaced apart from each other in the first direction D1. The fourth film magnetic patterns 240 may be connected to the second film magnetic input section 420.
[0090] In one embodiment, the fourth film magnetic pattern 240 may be disposed between each of the third film magnetic patterns 230. The third film magnetic pattern 230 and the fourth film magnetic pattern 240 may improve the alignment precision of the film FLM in the first direction D1.
[0091] The first film magnetic input unit 410 can be connected to the first film magnetic pattern 210 and the third film magnetic pattern 230. The first film magnetic input unit 410 can input the second magnetism to the first film magnetic pattern 210 and the third film magnetic pattern 230. Thus, the first film magnetic pattern 210 and the third film magnetic pattern 230 can have the second magnetism (e.g., N pole).
[0092] The second film magnetic input unit 420 can be connected to the second film magnetic pattern 220 and the fourth film magnetic pattern 240.
