In a plan view, a first peel force of the first protective film relative to the window may be greater than a second peel force of the second protective film relative to the window, a first shortest distance from a first end of the window to a first end of the first protective film may be less than a second shortest distance from a second end of the window to a second end of the first protective film, and the second protective film may have a rectangular shape including rounded corners.

[0023] According to the implementation method, in the plan view, the third shortest distance from the first end of the window to one end of the second protective film can be greater than the first shortest distance and the second shortest distance.

[0035] The illustrative, non-limiting embodiments will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.

[0036] In this specification and claims, for the purposes of its meaning and description, the phrase "at least one of..." is intended to include the meaning of "at least one selected from the group consisting of...". For example, "at least one of A and B" can be understood to mean "A, B, or A and B".

It will also be understood that, unless expressly defined herein, terms (such as those defined in common dictionaries) shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and in this disclosure, and shall not be interpreted in an ideal or overly formal sense.

[0038] Figure 1 This is a schematic plan view showing a window module according to an embodiment. Figure 2 It is shown Figure 1 A schematic cross-sectional view of the window module. For example, Figure 2 It can be along Figure 1 A schematic cross-sectional view taken from line I-I'.

[0039] Reference Figure 1 and Figure 2 The window module 1000 according to the embodiment may include a window 100, a first protective film 200 and a second protective film 300.

[0040] Window 100 may include a first film 110, a first adhesive layer 120, and a light-shielding pattern 130. Window 100 may also include functional layers such as a hard coating 140 and a low-reflection layer. Window 100 may be disposed in a lower structure (e.g., Figure 6It is mounted on the lower structure (2000) and can protect the lower structure from external forces.

[0041] The first membrane 110 may comprise transparent glass or transparent plastic. For example, the first membrane 110 may comprise ultrathin tempered glass (UTG), polyethylene terephthalate (PET), polyimide (PI), polyethersulfone (PS), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyarylate, polycarbonate (PC), polyarylene ether sulfone, etc. The thickness of the first membrane 110 may be greater than about 30 μm and less than about 80 μm. Therefore, the first membrane 110 may possess flexible properties.

[0042] The first adhesive layer 120 can be laminated to the first film 110. For example, the first adhesive layer 120 can be an optically transparent adhesive (OCA), an optically transparent adhesive resin (OCR), a pressure-sensitive adhesive (PSA), etc. The first adhesive layer 120 and the first film 110 can have substantially the same area. Therefore, the first adhesive layer 120 can attach or bond the second protective film 300 to the first film 110. The first adhesive layer 120 can also attach the lower structure 2000 to the first film 110.

[0043] A light-shielding pattern 130 may be disposed between the first film 110 and the first adhesive layer 120. The light-shielding pattern 130 can block light. In an embodiment, the light-shielding pattern 130 may be disposed around the outer portion of the first film 110. The light-shielding pattern 130 may be spaced a predetermined distance from the edge of the first film 110. For example, the light-shielding pattern 130 may be disposed corresponding to the non-emitting area of ​​the lower structure 2000. Therefore, the display device (e.g., Figure 9 Light leakage from the display device (3000).

[0044] A hard coating 140 may be disposed on the first film 110. For example, the hard coating 140 may comprise a silicone resin (e.g., silsesquioxane (SSQ)). The hard coating 140 may be processed to have anti-fingerprint properties.

[0045] The first protective film 200 can be disposed on the first surface S1 of the window 100. For example, the first protective film 200 can have a rectangular shape including rounded corners. The first protective film 200 can protect the window 100 during the transportation process. During the manufacturing process of the display device 3000, the first protective film 200 can be removed from the window 100.

[0046] The first protective film 200 may include a second film 210 and a second adhesive layer 220.

[0047] The second film 210 may include transparent glass or transparent plastic. For example, the second film 210 may include glass, ultra-thin tempered glass (UTG), polyethylene terephthalate (PET), polyimide (PI), polyethersulfone (PS), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyarylate, polycarbonate (PC), polyarylene ether sulfone, etc. The second film 210 can protect window 100.

[0048] The second adhesive layer 220 can be disposed between the hard coating layer 140 and the second film 210. For example, the second adhesive layer 220 can be an optically clear adhesive (OCA), an optically clear adhesive resin (OCR), a pressure-sensitive adhesive (PSA), etc. The second adhesive layer 220 and the second film 210 can have substantially the same area. Therefore, the second adhesive layer 220 can attach the hard coating layer 140 to the second film 210.

[0049] The second protective film 300 can be applied to the second surface S2 of the window 100, which is opposite to the first surface S1. The second protective film 300 can protect the window 100 during transportation. The second protective film 300 can be removed from the window 100 during the manufacturing process of the display device 3000.

[0050] The second protective film 300 may include transparent glass or transparent plastic. For example, the second protective film 300 may include glass, ultra-thin tempered glass (UTG), polyethylene terephthalate (PET), polyimide (PI), polyethersulfone (PS), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), polyarylate, polycarbonate (PC), polyarylene ether sulfone, etc.

[0051] In some embodiments, the second protective film 300 may not include an adhesive layer. For example, a first adhesive layer 120 may attach the second protective film 300 to the first film 110. Therefore, the peel force of the second protective film 300 relative to the window 100 can be reduced.

[0052] Peel force can refer to the force required to separate the release paper (e.g., the second protective film 300) from the adhesive layer (e.g., the first adhesive layer 120). Peel force can be measured by known methods. For example, peel force can be measured at room temperature and can be measured by removing the release paper at a peel rate (or detachment rate) of about 300 mm / min at about 90°. However, the methods for measuring peel force are not limited to the methods described above.

[0053] In this embodiment, the first peel force of the first protective film 200 relative to the window 100 can be greater than the second peel force of the second protective film 300 relative to the window 100. For example, the first peel force can be greater than about 10 gf / in and less than about 30 gf / in. The second peel force can be greater than about 1 gf / in and less than about 6 gf / in.

[0054] The first peeling force can be greater than the second peeling force. Therefore, when the second protective film 300 is removed from the window 100, no air bubbles may be generated between the first protective film 200 and the window 100.

[0055] The first peel force can be less than about 30 gf / in. Therefore, when the first protective film 200 is removed from the window 100, no air bubbles can be generated between the lower structure 2000 and the window 100.

[0056] The second peel force can be less than about 6 gf / in. Therefore, the second protective film 300 can be easily removed from the window 100.

[0057] In this embodiment, the first thickness TH1 of the first protective film 200 can be greater than the second thickness TH2 of the second protective film 300. For example, the first thickness TH1 can be greater than about 100 μm and less than about 150 μm. The second thickness TH2 can be greater than about 50 μm and less than about 100 μm. Since the first thickness TH1 of the first protective film 200 is greater than about 100 μm, defects caused by foreign matter pressing against the surface of the first film 110 can be prevented.

[0058] Figure 3 It is shown Figure 1 A schematic plan view of the shortest distance in the window module.

[0059] Reference Figure 2 and Figure 3 The lower structure 2000 may include a display area DA and a circuit area CA adjacent to the display area DA. Pixels PX may be disposed in the display area DA, and images may be displayed in the display area DA. Circuit boards, driving circuits, and driving lines may be disposed in the circuit area CA. For example, in the circuit area CA, a flexible printed circuit board FPCB, a data driving circuit DIC disposed on the flexible printed circuit board FPCB, and a fan-out line FO connecting the data driving circuit DIC and the pixel PX may be disposed.

[0060] Window 100 can be installed on the lower structure 2000. Window 100 and lower structure 2000 can have approximately the same area.

[0061] In one embodiment, window 100 may include a circuit-corresponding area CCA and a display-corresponding area DCA. The circuit-corresponding area CCA may correspond to the circuit area CA, and the display-corresponding area DCA may correspond to the display area DA. The circuit-corresponding area CCA may include a first end ED1 of window 100, and the display-corresponding area DCA may include a third end ED3 of window 100.

[0062] In one embodiment, the first protective film 200 may include a second end ED2 adjacent to the first end ED1 and a fourth end ED4 adjacent to the third end ED3. The second protective film 300 may include a fifth end ED5 adjacent to the second end ED2.

[0063] In the implementation, in the plan view, the first shortest distance W1 from the first end ED1 to the second end ED2 can be less than the second shortest distance W2 from the third end ED3 to the fourth end ED4. For example, the first shortest distance W1 can be greater than about 0.5 mm and less than about 1 mm. The second shortest distance W2 can be greater than about 1 mm and less than about 2 mm. Since the first shortest distance W1 is less than about 1 mm, when the first protective film 200 is removed, the first protective film 200 can avoid contacting the lower structure 2000 in the circuit region CA. Therefore, the components disposed in the circuit region CA can be protected from the influence of the first protective film 200. For example, the components can avoid entanglement with the first protective film 200.

[0064] In the implementation, in the plan view, the third shortest distance W3 from the first end ED1 to the fifth end ED5 can be greater than each of the first shortest distance W1 and the second shortest distance W2. For example, the third shortest distance W3 can be greater than about 3 mm and less than about 13 mm. Since the third shortest distance W3 is set large enough, the picker of the process facility can grasp or hold the second protective film 300 during the transport of the window module 1000 or during the manufacturing process of the display device 3000.

[0065] Figure 4 It is shown that it includes Figure 1 A schematic plan view of the second protective film in the window module.

[0066] Reference Figure 4 The second protective film 300 may have a rectangular shape including rounded corners 301. For example, the second protective film 300 may be processed such that the corners 301 have curvature. In an embodiment, the radius of curvature of the corners 301 may be greater than about 2 mm and less than about 10 mm. Because the second protective film 300 has a rectangular shape including rounded corners 301, the external force EF applied to the second protective film 300 can be dispersed. Therefore, the external force EF may not be applied to the window 100, and the window 100 can be protected.

[0067] Figures 5 to 9 This is a schematic cross-sectional view illustrating a method for manufacturing a display device according to an embodiment.

[0068] Reference Figure 1 and Figure 5 In the method of manufacturing a display device 3000, a window module 1000 may be provided, including a window 100, a first protective film 200 disposed on a first surface S1 of the window 100, and a second protective film 300 disposed on a second surface S2 of the window 100 opposite to the first surface S1.

[0069] The second protective film 300 can be removed from the window 100. In this case, as described above, the second peel force of the second protective film 300 relative to the window 100 can be less than about 6 gf / in. Therefore, the second protective film 300 can be easily removed from the window 100 in region A. As described above, the second peel force can be less than the first peel force. Therefore, when the second protective film 300 is removed from the window 100, no bubbles can be generated in region B.

[0070] Reference Figure 1 , Figure 6 and Figure 7 The lower structure 2000 can be disposed on the second surface S2 of the window 100. The lower structure 2000 may include a display panel 400, a third adhesive layer 500, a third protective film 600, a fourth adhesive layer 700, a buffer member 800, and a support member 900.

[0071] like Figure 7 As shown, the display panel 400 may include a substrate 410, a buffer layer 420, an active pattern 430, a first insulating layer ILD1, a gate electrode 440, a second insulating layer ILD2, a source electrode 451, a drain electrode 452, a via insulating layer VIA, a first electrode 461, an emitter layer 462, a second electrode 463, a pixel defining layer PDL, a first inorganic layer 471, an organic layer 472, and a second inorganic layer 473.

[0072] The substrate 410 may include glass, quartz, plastic, etc. For example, the substrate 410 may be a plastic substrate and may include polyimide (PI). In an embodiment, the substrate 410 may have a structure in which at least one polyimide layer and at least one barrier layer are alternately stacked.

[0073] A buffer layer 420 may be disposed on the substrate 410. The buffer layer 420 may include silicon oxide, silicon nitride, etc. The buffer layer 420 can prevent impurities from diffusing into the active pattern 430.

[0074] An active pattern 430 may be disposed on a buffer layer 420. For example, the active pattern 430 may include silicon semiconductors, oxide semiconductors, etc. The silicon semiconductor may include amorphous silicon or polycrystalline silicon. The active pattern 430 may allow current to pass through or block in response to a gate signal provided to the gate electrode 440. For example, ions may be selectively implanted into the active pattern 430. The active pattern 430 may include source and drain regions implanted therein, and channel regions where no ions are implanted.

[0075] The first insulating layer ILD1 may include an insulating material and may cover the active pattern 430. For example, the first insulating layer ILD1 may include silicon oxide, silicon nitride, titanium oxide, tantalum oxide, etc. The first insulating layer ILD1 can electrically insulate the active pattern 430 from the gate electrode 440.

[0076] The gate electrode 440 may include metals, alloys, conductive metal oxides, etc., and may be disposed on the first insulating layer ILD1.

[0077] The second insulating layer ILD2 may include an insulating material and may cover or overlap the gate electrode 440. For example, the second insulating layer ILD2 may include silicon oxide, silicon nitride, titanium oxide, tantalum oxide, etc. The second insulating layer ILD2 can electrically insulate the gate electrode 440 from the source electrode 451 and from the drain electrode 452.

[0078] The source electrode 451 and drain electrode 452 may include metals, alloys, conductive metal oxides, etc., and may be disposed on the second insulating layer ILD2. For example, the source electrode 451 and drain electrode 452 may include silver (Ag), silver alloys, molybdenum (Mo), molybdenum alloys, aluminum (Al), aluminum 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.

[0079] The via insulating layer VIA may cover or overlap with the source electrode 451 and drain electrode 452, may include an organic insulating material, and may have a generally flat top surface. For example, the via insulating layer VIA may include photoresist, polyacrylic resin, polyimide resin, acrylic resin, etc.

[0080] The first electrode 461 can be disposed on the through-hole insulating layer VIA. The first electrode 461 may include a metal, alloy, or conductive metal oxide. For example, the first electrode 461 may include silver (Ag), alloys including silver, molybdenum (Mo), alloys including molybdenum, aluminum (Al), alloys including aluminum, 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. The first electrode 461 can receive a first voltage from the drain electrode 452.

[0081] The pixel defining layer (PDL) can be disposed on the via insulating layer (VIA), and an opening exposing a portion of the upper surface of the first electrode 461 can be formed in the pixel defining layer (PDL). For example, the pixel defining layer (PDL) can include organic materials such as polyimide resin (e.g., photosensitive polyimide resin (PSPI)), photoresist, polyacrylic resin, and acrylic resin, or inorganic materials such as silicon oxide and silicon nitride.

[0082] The emitter layer 462 can be disposed on the first electrode 461. The emitter layer 462 can have a multilayer structure including an organic emitter layer, a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer.

[0083] The second electrode 463 can be disposed on the emitter layer 462 and can receive the second voltage. The second electrode 463 may include metals, alloys, conductive metal oxides, etc. For example, the second electrode 463 may include silver (Ag), alloys including silver, molybdenum (Mo), alloys including molybdenum, aluminum (Al), alloys including aluminum, 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.

[0084] The voltage difference between the first voltage and the second voltage can cause the emitting layer 462 to generate light. Therefore, the first electrode 461, the emitting layer 462, and the second electrode 463 can be defined as organic light-emitting diodes.

[0085] A thin-film encapsulation layer can be disposed on the second electrode 463. The thin-film encapsulation layer can prevent moisture and oxygen from penetrating from the outside. For example, the thin-film encapsulation layer can have a structure in which a first inorganic layer 471, an organic layer 472, and a second inorganic layer 473 are stacked alternately.

[0086] Refer again Figure 6 The third adhesive layer 500 can be disposed below the display panel 400. For example, the third adhesive layer 500 can be optically clear adhesive (OCA), optically clear adhesive resin (OCR), pressure-sensitive adhesive (PSA), etc.

[0087] The third protective film 600 can be disposed below the third adhesive layer 500. The third protective film 600 can prevent moisture and oxygen from penetrating from the outside and can absorb external impacts.

[0088] The fourth adhesive layer 700 can be disposed below the third protective film 600. For example, the fourth adhesive layer 700 can be an optically transparent adhesive (OCA), an optically transparent adhesive resin (OCR), a pressure-sensitive adhesive (PSA), etc.

[0089] A cushioning member 800 may be disposed below the fourth adhesive layer 700. The cushioning member 800 protects the display panel 400 by mitigating or absorbing external impacts. For example, the cushioning member 800 may include materials such as pads or sponges capable of mitigating or absorbing impacts by containing air. The cushioning member 800 may include acrylic resin, polyurethane, thermoplastic polyurethane, latex, polyurethane foam, polystyrene foam, etc.

[0090] The support member 900 can be disposed below the buffer member 800. The support member 900 can support the display panel 400. For example, the support member 900 can include Invar alloy, stainless steel (SUS), titanium (Ti), copper (Cu), etc., which are alloys of nickel (Ni) and iron (Fe). The hole H overlapping the folding area FA can be formed in the support member 900, and the window 100 and the lower structure 2000 are folded in the folding area FA.

[0091] Reference Figure 1 and Figure 8The first protective film 200 can be removed from the window 100. In this case, as described above, the first peel force of the first protective film 200 relative to the window 100 can be less than about 30 gf / in. Therefore, when the first protective film 200 is removed from the window 100, no air bubbles are generated in the region C between the lower structure 2000 and the window 100. As described above, since the first shortest distance W1 from the first end ED1 to the second end ED2 is less than about 1 mm, the first protective film 2000 does not need to contact the lower structure 2000 in the circuit region CA. Therefore, the components disposed in the circuit region CA can be protected from the influence of the first protective film 200. For example, the components do not need to become entangled with the first protective film 200.

[0092] Reference Figure 1 and Figure 9 A display device 3000 can be manufactured. For example, the display device 3000 may include a window 100 and a lower structure 2000.

[0093] The window module according to embodiments of this disclosure may include a window, a first protective film disposed on the window, and a second protective film disposed below the window. A first peel force of the first protective film relative to the window may be greater than a second peel force of the second protective film relative to the window. In a plan view, a first shortest distance from one end of the window to one end of the first protective film may be less than a second shortest distance from the other end of the window to the other end of the first protective film. A first thickness of the first protective film may be greater than a second thickness of the second protective film. The second protective film may have a rectangular shape including rounded corners. Therefore, when the first and second protective films are removed from the window, air bubbles may not be generated, the second protective film can be easily removed from the window, defects caused by foreign matter pressing on the surface of the first film included in the window can be prevented, the first protective film may not contact the lower structure in the circuit area, and the external force applied to the second protective film can be dispersed. Therefore, the window can be transported stably, and the process yield of the display device can be improved.

[0094] Although specific embodiments and implementations have been described herein, other embodiments and modifications will be apparent from that description. Therefore, this disclosure is not limited to these embodiments, but rather to the broader scope of the appended claims and various obvious modifications and equivalent arrangements that will be apparent to those skilled in the art.
