For the sake of convenience, Figure 1 The display device DD is shown used as a smartphone.

[0050] In an embodiment, the display device DD may have a rectangular shape including short sides parallel to the first direction DR1 and long sides parallel to the second direction DR2 . However, the shape of the display device DD is not limited thereto.

[0051] The display device DD may display an image toward the third direction DR3 on a display surface parallel to each of the first direction DR1 and the second direction DR2. The display surface displaying the image may correspond to the front surface of the display device DD. In addition to dynamic images, the image may also include a still image.

[0052] The display device DD according to an embodiment can sense the user's input applied from the outside.

However, it is not limited thereto, and the area for sensing the user's input can also be provided in the non-display area NDA or in all areas of the display surface.

[0057] Figure 2 is an exploded perspective view of a display device according to an embodiment of the present invention. Figure 3 is along Figure 1 A cross-sectional view taken along the line A-A'.

[0058] Reference Figure 2 as well as Figure 3 The display device DD may include a display module DM, a window component WM and a lower casing BC.

[0059] The display module DM may include a display panel DP, a touch layer TSL, and an optical layer OCA.

[0060] The display panel DP may include a plurality of pixels. The plurality of pixels may be arranged in a matrix direction. The shape of each pixel may be a rectangle or a square on a plane, but is not limited thereto, and may also be a rhombus shape with each side inclined relative to the second direction DR2 or the first direction DR1. Each pixel may include a light emitting area. Each light emitting area may also be the same shape as the pixel, but may also be different. For example, when the shape of the pixel is a rectangle, the shape of the light emitting area of ​​the corresponding pixel may have various shapes such as a rectangle, a rhombus, a hexagon, an octagon, a circle, etc.

[0061] Examples of the display panel DP include an organic light emitting display panel, a micro LED display panel, a nano LED display panel, a quantum dot light emitting display panel, a liquid crystal display panel, a plasma display panel, a field emission display panel, an electrophoretic display panel, an electrowetting display panel, etc. Below, as an example of the display panel DP, an organic light emitting display panel is illustrated, but the present invention is not limited thereto, and other display panels may also be applied if the same technical concept can be applied.

[0062] The display panel DP may include a flexible substrate including a flexible polymer material such as polyimide, and thus the display panel DP may be bent, folded, or rolled.

[0063] The display panel DP may include a curved area BA. Centered on the curved area BA, the display panel DP may be divided into a main area MA located on one side of the curved area BA in the second direction DR2 and a sub-area SA located on the other side of the curved area BA in the second direction DR2.

[0064] The display area of ​​the display panel DP is configured in the main area MA. In one embodiment, the peripheral edge portion of the display area in the main area MA, the entire curved area BA, and the entire sub-area SA may be non-display areas. However, this is not limited to this, and the curved area BA and / or the sub-area SA may also include a display area.

[0065] The main area MA may have a shape that is substantially similar to the planar shape of the display module DM. The main area MA may be a flat area located on a plane. However, this is not limited thereto, and in addition to the edge (edge) connected to the bending area BA in the main area MA, at least one of the remaining edges may also be bent to form a curved surface or bend in a vertical direction.

[0066] The curved area BA is connected to the other side of the main area MA in the second direction DR2. For example, the curved area BA may be connected through the lower short side of the main area MA. The width of the curved area BA (the width in the first direction DR1) may be smaller than the width of the main area MA adjacent to the curved area BA (the width in the first direction DR1). The connection between the main area MA and the curved area BA may have an L-shaped cut shape.

[0067] In the curved area BA, the display panel DP may be curved in a curvature along the lower side direction in the thickness direction, in other words, along the opposite direction of the display surface. The curved area BA may have a constant radius of curvature, but is not limited thereto, and may have different radii of curvature according to the intervals. As the display panel DP is curved in the curved area BA, the surface of the display panel DP may be flipped. That is, one side of the display panel DP facing upward is directed outward through the curved area BA, and then changes to face downward.

[0068] The sub-region SA extends from the bending region BA. The sub-region SA may start to extend in a direction parallel to the main region MA after the bending ends. The sub-region SA may overlap the main region MA in a thickness direction of the display panel DP.

[0069] A driving chip DIC may be configured in the sub-area SA. The driving chip DIC may include an integrated circuit that drives the display panel DP. The integrated circuit may include an integrated circuit for a display and / or an integrated circuit for a touch unit. However, it is not limited thereto, and the integrated circuit for the display and the integrated circuit for the touch unit may be provided by separate chips or may be integrated in one chip.

[0070] A pad portion may be disposed at an end portion of the sub-area SA of the display panel DP.

[0071] The pad portion may include a plurality of display signal wiring pads and a touch signal wiring pad. The driving substrate FCB may be connected to the pad portion. The driving substrate FCB may be a flexible printed circuit substrate or a film.

[0072] exist Figure 2 2A and 2B illustrate that the bending area BA is not bent but expanded, but the display panel DP may be accommodated in the lower case BC in a state in which the bending area BA is bent.

[0073] The touch layer TSL may be disposed above the display panel DP. In one embodiment, the touch layer TSL may be provided as a whole with the display panel DP. However, it is not limited thereto, and the touch layer TSL may also be provided as a panel or film different from the display panel DP and attached to the display panel DP.

[0074] The touch layer TSL includes a touch area. The touch area may be an area for realizing sensing of a touch input. The touch area may overlap with the display area DA. That is, the display area DA may be an area for realizing both display and sensing of a touch input.

[0075] The optical layer OCA may be disposed above the touch layer TSL, but is not limited thereto.

[0076] The optical layer OCA can play a role in reducing external light reflection. The optical layer OCA can be attached in the form of a polarizing film. At this time, the optical layer OCA can polarize the light passing through, and the optical layer OCA is attached above the touch layer TSL through an adhesive layer. The optical layer OCA in the form of a polarizing film can also be omitted. The optical layer OCA can play a role in reducing external light reflection.

[0077] The window component WM may be disposed above the display module DM. The window component WM may protect the display module DM from external impact. The window component WM may have an optically transparent property. The window component WM may be multi-layered.

[0078] The form component WM can be configured to overlap the display panel DP and cover the front of the display panel DP. The form component WM can have a shape that is roughly similar to the display panel DP in plane, but its size is larger than the display panel DP. For example, the form component WM can protrude outward from the display panel DP. The planar shape of the form component WM can be the same as the planar shape of the display module DM. For example, the planar shape of the form component WM can be roughly circular, but is not limited to this, and can have various shapes, for example, it can be a polygon such as a quadrilateral or an ellipse.

[0079] The lower housing BC can be arranged behind the outermost part of the electronic device to accommodate the display module DM and the window component WM. The lower housing BC can be formed by assembling multiple parts, or include a main body of injection molding. The lower housing BC can include at least one of a plastic material, a metal material and a glass material, and include a color coating. For example, according to one example, the lower housing BC can be a flat glass with a transparent, translucent or opaque color coating. In addition, the lower housing BC can include a glass material with a color coating. This lower housing BC may include a bottom FR for accommodating the display module DM and the window component WM and a plurality of side walls SD bent from the bottom FR. A space BC-S for accommodation can be defined by the bottom FR and the side walls SD. The side wall SD can surround a portion of the side of the window component WM. A portion of the window component WM can protrude above the side wall SD of the lower housing BC.

[0080] In one embodiment, the window component WM may include two layers. The window component WM may include a main window WM-M and a protection window WM-S.

[0081] The main form WM-M is arranged above the display module DM. The protection form WM-S can be arranged above the main form WM-M. The protection form WM-S can be arranged to be farther away from the display module DM than the main form WM-M.

[0082] The main window WM-M can be completely accommodated in the lower case BC. For example, the main window WM-M can be configured in the space BC-S of the lower case BC. The side of the main window WM-M can be completely surrounded by the side wall SD of the lower case BC.

[0083] A portion of the side of the protection window WM-S may be surrounded by the side wall SD. A portion of the protection window WM-S may protrude above the side wall SD of the lower case BC. Alternatively, a portion of the protection window WM-S may be disposed in the space BC-S of the lower case BC, and a portion of the protection window WM-S may protrude above the space BC-S.

[0084] Reference Figure 5 as well as Figure 6 Describes the form component WM in detail.

[0085] The display module DM and the main window WM-M may be bonded by a transparent adhesive. The adhesive force of the adhesive disposed between the display module DM and the main window WM-M should be stronger than the adhesive force of the weak adhesive layer 110.

[0086] Figure 4 FIG. 4 is a schematic cross-sectional view showing an exemplary stacked structure of a display module according to an embodiment of the present invention.

[0087] Reference Figure 4 The display panel DP may include a substrate SUB, a circuit driving layer DRL, a light emitting layer EML, and an encapsulation layer ENL stacked in sequence. A touch layer TSL and an optical layer OCA may be further configured on the encapsulation layer ENL, but at least one of them may be omitted.

[0088] The substrate SUB can support the structure arranged above.

[0089] A circuit driving layer DRL may be disposed above the substrate SUB. The circuit driving layer DRL may include a circuit for driving the light emitting layer EML of the pixel. The circuit driving layer DRL may include a plurality of thin film transistors.

[0090] The light emitting layer EML may be disposed above the circuit driving layer DRL. The light emitting layer EML may include an organic light emitting layer or an inorganic light emitting layer. The light emitting layer EML may emit light at various brightnesses according to a driving signal transmitted from the circuit driving layer DRL.

[0091] An encapsulation layer ENL may be disposed above the light emitting layer EML. The encapsulation layer ENL may include an inorganic film or a laminated film of an inorganic film and an organic film. As another example, glass or an encapsulation film may also be used as the encapsulation layer ENL.

[0092] A touch layer TSL and an optical layer OCA may be disposed above the encapsulation layer ENL. Figure 2 In another embodiment, one or more of the touch layer and the optical layer may be omitted.

[0093] Figure 5 It is used to illustrate Figure 3 A schematic diagram of the form components including the main form and the protection form, Figure 6 It is used to illustrate Figure 5 A schematic diagram of the form components that combine the main form and the protection form.

[0094] Reference Figure 5 as well as Figure 6 The window member WM may include a main window WM-M, a weak adhesive layer 110, a protection window WM-S, and a light shielding portion BM.

[0095] The main window WM-M can be configured to overlap the display panel DP and cover the front of the display panel DP. The window component WM can have a shape that is roughly similar to the display panel DP in plane, but its size is larger than the display panel DP. The width of the first direction DR1 and the second direction DR2 of the main window WM-M can be wider than the width of the display panel DP. For example, the main window WM-M can protrude outward from the display panel DP. The planar shape of the main window WM-M can be the same as the planar shape of the display module DM. For example, the planar shape of the main window WM-M can be roughly circular, but is not limited to this, and can have various shapes, for example, it can be a polygon such as a quadrilateral or an ellipse.

[0096] The thickness hm of the main window WM-M may have a range of 0.2 mm to 0.4 mm.

[0097] The main window WM-M may be a transparent material, made of plastic, glass or tempered glass. As an example, the main window WM-M may have any one of sapphire glass and gorilla glass or a laminated structure thereof. As another example, the main window WM-M may include any one of PET (polyethylene terephthalate), PC (polycarbonate), PES (polyethersulfone), PEN (polyethylenapthanate) and PNB (polynorbornene).

[0098] In addition, in one embodiment, the main window WM-M may be made of an ultraviolet curable resin, such as an optical clear resin (OCR). The protection window WM-S may overlap with the main window WM-M and protrude outward from the display panel DP. The plane shape of the protection window WM-S may have a shape similar to that of the main window WM-M, but the corners are different from each other. For example, the plane shape of the protection window WM-S may be a rectangle with rounded corners, but is not limited thereto.

[0099] The thickness hs of the protection window WM-S may be the same as or thinner than the thickness hm of the main window WM-M. The thickness hs of the protection window WM-S may have a range of 0.1 mm to 0.4 mm.

[0100] The protective window WM-S may include a synthetic resin film. For example, the protective window WM-S may include a polyimide film, but is not limited thereto. The protective window WM-S may include a plastic film as a base layer. The protective window WM-S may include any one of the plastic films selected from the group consisting of polyethersulfone (PES), polyacrylate, polyetherimide (PEI), polyethylenenaphthalate (PEN), polyethyleneterephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC), polyarylene ethersulfone (poly(arylene ethersulfone)) and combinations thereof. The material constituting the protective window WM-S is not limited to plastic resins and may include organic / inorganic composite materials. The protection window WM-S may include a porous organic layer and an inorganic substance filled in the pores of the organic layer. In addition, the protection window WM-S may be made of ultra-thin film type tempered glass or tempered glass material.

[0101] A weak adhesive layer 110 may be disposed below the protective window WM-S. The weak adhesive layer 110 includes a transparent and detachable adhesive substance. The detachable adhesive substance may be, for example, a pressure sensitive adhesive (PSA). A pressure sensitive adhesive (PSA) is an adhesive in which the adhesive substance acts when a pressure is applied to bond the adhesive to the adhesive surface. The strength of the bond is affected by the amount of pressure applied to the adhesive to the surface. The detachable adhesive substance may be used in various ways within the technical concept of the present invention, but an adhesive mixed with an acrylic polymer, a silicone polymer, or a thermosetting resin as a polyurethane polymer, or a thermosetting resin ultraviolet curing resin and a crosslinking agent, or a mixture thereof, or a copolymer thereof.

[0102] Since the protection window WM-S is configured on the main window WM-M, the main window WM-M and the weak adhesive layer 110 may be in direct contact.

[0103] On the other hand, a light shielding portion BM may be disposed behind the main window WM-M. The light shielding portion BM may block a portion of the light emitted from the display panel DP. Therefore, the light shielding portion BM may overlap with the non-display area NDA of the display panel DP and may not overlap with the display area DA. The light shielding portion BM may protrude outward from the display panel DP. The light shielding portion BM may be a black resin, but is not limited thereto. The light shielding portion BM may be provided as a material of various colors that blocks the travel of light. In another embodiment, the light shielding portion BM may be omitted.

[0104] Figure 7 is a schematic diagram for explaining a window component including a main window and a protection window according to another embodiment of the present invention, Figure 8 It is used to illustrate Figure 7 A schematic diagram of the form components that combine the main form and the protection form.

[0105] Figure 7 A disassembly and assembly auxiliary layer 120 is configured above the main form WM-M. At this point, Figure 5 as well as Figure 6 The display device according to the above embodiment is different. Figure 7 as well as Figure 8 Main description and Figure 5 as well as Figure 6 Different points.

[0106] The disassembly auxiliary layer 120 may be disposed above the main window WM-M. On the disassembly auxiliary layer 120, the weak adhesive layer 110 and the protection window WM-S may be disposed in sequence. The disassembly auxiliary layer 120 and the weak adhesive layer 110 may be in direct contact.

[0107] The disassembly auxiliary layer 120 increases the slip property by reducing the friction. The disassembly auxiliary layer 120 makes it easy to disassemble the protective window WM-S from the main window WM-M. Titanium dioxide (TiO 2 ) or silicon dioxide (SiO 2 ) is then coated with fluorine resin or silicon resin in an ECC (easy cleaning coating) manner to form a disassembly and assembly auxiliary layer 120. The disassembly and assembly auxiliary layer 120 can more effectively suppress the generation of bubbles when attaching the protective window WM-S. In addition, through the disassembly and assembly auxiliary layer 120, consumers can easily disassemble and assemble the protective window WM-S by themselves without separate tools. Compared with the embodiment in which the disassembly and assembly auxiliary layer 120 is not configured, the protective window WM-S can be more easily disassembled and assembled from the main window WM-M.

[0108] Fig. 9 According to another embodiment, Figure 1 A cross-sectional view taken along the line A-A'.

[0109] Fig. 9 At the point where the lower case BC includes the middle frame MF and the lower frame BF Figure 3 Different. Below, we will refer to Fig. 9 Main description and Figure 3 Different points.

[0110] The lower case BC may include a middle frame MF, a bonding layer AD, and a lower frame BF.

[0111] The middle frame MF can function as a coupling member for coupling the window member WM and the lower frame BF. The middle frame MF is disposed between the window member WM and the lower frame BF. For example, the middle frame MF can function as a bracket for fixing.

[0112] The display module DM is arranged between the middle frame MF and the form part WM. The rear of the display module DM and the upper surface of the middle frame MF may face each other, and the arrangement is separated so that a receiving space is provided between the rear of the display module DM and the upper surface of the middle frame MF, but it is not limited thereto. The receiving space may accommodate peripheral circuits of the electronic device such as a main drive system, a memory, and a battery.

[0113] The middle frame MF may include a middle plate MF-1 and a middle side wall MF-2.

[0114] The middle plate MF-1 may be disposed behind the display module DM. In this case, the middle plate MF-1 may include at least one opening portion through which a cable for electrical connection between a display driving circuit portion connected to the display module DM and a main driving system passes, and at least one recessed portion for disposing various electronic circuit components loaded on the electronic device.

[0115] The middle side wall MF-2 may be vertically coupled to the side surface of the middle panel MF-1 to support the contact surface with the window member WM.

[0116] The bonding layer AD is located between the middle frame MF and the lower frame BF, and bonds the middle frame MF and the lower frame BF to each other. The bonding layer AD may be an adhesive tape coated with an adhesive substance on both sides and having a waterproof or dustproof function. The bonding layer AD has a constant width and is formed along the edge of the middle frame MF. Therefore, the bonding layer AD preferably corresponds to the shape and size of the middle frame MF. That is, if the middle frame MF has a circular shape, the bonding layer AD also has a circular shape, and if the middle frame MF has a quadrilateral shape, the bonding layer AD also has a quadrilateral shape.

[0117] In addition, similar to the middle frame MF, the bonding layer AD may have a ring shape with a hole in the center, but is not limited thereto. If the constant width is too thick, it will be exposed to the outside of the middle frame MF and affect the display device ( Figure 1 The constant width may be formed differently according to the appearance and material of the window member WM and the middle frame MF. In fact, the optimal width that can fully ensure the user's field of vision and the adhesion is experimentally selected. The bonding layer AD can be formed by a single layer or multiple layers.

[0122] Fig.11 FIG. 1 is a diagram showing steps for preparing a display device including replacing an object protection window in one embodiment. Fig.11 , one embodiment of the preparation includes a step (S110) of replacing the display device of the object protection window can be referred to Figures 1 to 6 The illustrated preparation includes a display device including a window member WM, a display module DM, and a lower case BC having a replacement protection window WM-S1. Here, the replacement protection window WM-S1 may be damaged.

[0123] Fig.12 is a summary showing Fig.11 The figure shows the steps of removing the protective window of the replacement object above the display device. Fig.12 , the step of removing the replacement object protection window (S120) may be a step of removing the replacement object protection window WM-S1 from the main window WM-M in the window part WM of the display device.

[0124] The main window WM-M and the replacement object protection window WM-S1 are bonded by the weak adhesive layer 110, and the user can easily separate the replacement object protection window WM-S1 from the main window WM-M. For example, the user can easily remove the replacement object protection window WM-S1 using a small tool such as a scraper or a scraper.

[0125] Fig.13 FIG. 1 is a diagram schematically showing the steps for preparing a new protection form. Fig.13 , the step of preparing a new protection window (S130) may be a step of preparing a protection window WM-S2 having a weak adhesive layer 110 disposed thereunder.

[0126] If the weak adhesive layer 110 is contaminated, the adhesive force may be reduced. Therefore, if the protective film 200 is prepared in a state of being attached to the weak adhesive layer 110 , the protective film 200 of the weak adhesive layer 110 is peeled off for the next step.

[0127] Fig.14 FIG. 1 is a diagram schematically showing the steps for attaching a new protective window. Fig.14 The step of attaching a new protection window (S140) is in Fig.12 The main form WM-M is attached as follows Fig.13 Prepare the steps for protecting the WM-S2 form in this way.

[0128] The protection window WM-S2 can be adhered to the main window WM-M by the weak adhesive layer 110 disposed under the protection window WM-S2.

[0129] Before providing the protection window WM-S2 on the main window WM-M, it is preferable to wipe the contaminants on the upper surface of the main window WM-M. When contaminants exist on the attachment surface, the adhesive force may be reduced.

[0130] As shown in the figure, when the window of the display device is damaged due to impact or the like, the user can replace only the uppermost protective window by himself without replacing the entire window. Therefore, the convenience of the user can be improved.
