[0044] Hereinafter, the embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals will be used for the same components in the accompanying drawings, and repeated descriptions of the same components will be omitted.

[0045] Figure 1 FIG. 1 is a top view of a display device according to an embodiment of the present invention. Figure 2 It shows Figure 1 An exploded perspective view of a display device. Figure 3 It shows Figure 1 A cross-sectional view of a window included in a display device. Figure 4 It shows Figure 1 A top view of a display panel included in a display device.

[0046] Reference Figure 2 The display device DD may include a window WN, an adhesive layer AL, a display panel PA, a cover panel CP, a shape maintaining portion SP, and a circuit board CB.

[0047] The shape-maintaining portion SP, the cover plate CP, the display panel PA, the adhesive layer AL, and the window WN may be sequentially arranged on the circuit board CB. That is, the window WN, the adhesive layer AL, the display panel PA, the cover plate CP, the shape-maintaining portion SP, and the circuit board CB may be sequentially arranged along the first direction DR1.

[0048] The window WN can protect the structure disposed below the window WN from external environment, impact, etc. The window WN can be optically transparent. For example, the window WN can be made of glass, a transparent polymer material, etc.

[0049] Reference Figure 3 In one embodiment, the window WN may have a dome shape. For example, the window WN may have a dome-shaped cross-section that is convex and curved in a second direction DR2, which is opposite to the first direction DR1. Because the window WN has a dome shape, it can define an interior space. The window WN can accommodate structures disposed below the window WN within the interior space.

[0050] The adhesive layer AL may be disposed below the window WN. The adhesive layer AL may combine the window WN with the structure disposed below the adhesive layer AL. The adhesive layer AL may be optically transparent. For example, the adhesive layer AL may be an optically clear adhesive film (OCA), an optically clear resin (OCR), or a pressure sensitive adhesive (PSA). Thus, the effect of the adhesive layer AL on the visibility of the image generated on the display panel PA may be reduced.

[0051] The display panel PA may be disposed below the adhesive layer AL. For example, the display panel PA may be combined with the window WN via the adhesive layer AL.

[0052] Reference Figure 4 The display panel PA may include a display portion DP and a bending portion BP. The display portion DP may include a display area DA and a non-display area NDA.

[0053] The display area DA may be an area for displaying an image. A plurality of pixels PX may be configured in the display area DA. Each pixel PX may be defined as a minimum luminous unit capable of displaying light. For example, the pixels PX may be arranged in a matrix across the display area DA. As another example, the pixels PX may be arranged in a matrix at the center of the display area DA and in a stepped configuration at the edges of the display area DA. However, the present invention is not limited thereto, and the pixels PX may be configured in a variety of configurations within the range of displaying an image on the display area DA.

[0054] Signal lines such as gate lines and data lines can be configured in the display area DA. Each pixel can be connected to one of these signal lines. Each pixel can receive gate signals, data signals, and the like from these signal lines. Thus, an image can be displayed in the display area DA in the second direction DR2. The image displayed in the display area DA can be provided outside the display device DD. In other words, the display area DA of the display panel PA can be defined as the display area DA of the display device DD.

[0055] In one embodiment, the display area DA may have a curvature. For example, the display area DA may have a circular shape with an overall constant curvature on a plane. However, the present invention is not limited thereto, and the display area DA may have various shapes, such as a polygonal plane shape or an elliptical plane shape.

[0056] The non-display area NDA may be an area where no image is displayed. A driving unit for driving the pixel PX may be arranged in the non-display area NDA. The non-display area NDA may surround at least a portion of the display area DA. For example, the non-display area NDA may surround the entire display area DA. The non-display area NDA may have a shape corresponding to the shape of the display area DA. For example, the display area DA may have a circular plane shape, at least a portion of the non-display area NDA on the plane is in a straight line shape, and the remaining area excluding the portion has a circular plane shape with the same curvature as that of the display area DA. However, the present invention is not limited thereto, and the non-display area NDA may have a variety of shapes such as a polygonal plane shape and an elliptical plane shape.

[0057] Reference Figure 4The bent portion BP may extend from the display portion DP in a third direction DR3, and the third direction DR3 may intersect the first direction DR1 and the second direction DR2, respectively. For example, the third direction DR3 may be perpendicular to the first direction DR1 and the second direction DR2, respectively. The bent portion BP may be a region where no image is displayed. The bent portion BP may be a region where the display panel PA is curved. The display panel PA may be curved so that at least a portion of the bent portion BP overlaps with the display portion DP. Specifically, the display panel PA may be curved so that the bent portion BP is located on the back side of the display portion DP.

[0058] The cover plate CP may be disposed below the display panel PA. The cover plate CP may cover the lower surface of the display panel PA. The cover plate CP may have a single-layer or multi-layer structure. For example, the cover plate CP may be a stacked structure of a cushion member, a heat dissipation member, a conductive film, and the like. The cushion member may absorb impact applied to the display panel PA. The heat dissipation member may prevent heat from being applied to the display panel PA, or may diffuse heat generated from the display panel PA. The conductive film may offset electromagnetic interference applied to the display panel PA.

[0059] The shape retaining portion SP may be disposed below the display panel PA. The shape retaining portion SP may retain the shape of a structure disposed below the shape retaining portion SP. Detailed description of this will be given later.

[0060] The circuit board CB may be disposed below the shape maintaining portion SP and connected to the bent portion BP of the display panel PA. That is, the bent portion BP of the display panel PA may be bent toward the first direction DR1 and connected to the circuit board CB.

[0061] The circuit board CB may be configured with various components, such as a driver and a processor, for driving the display panel PA. In one embodiment, these components may be configured on a first surface of the circuit board CB adjacent to the shape-preserving portion SP. In another embodiment, these components may be configured on a second surface of the circuit board CB spaced apart from the shape-preserving portion SP.

[0062] In one embodiment, the display device DD can be applied to a wearable device. For example, the display device DD can be applied to a watch-type device. However, the present invention is not limited thereto, and the display device DD can be applied to a variety of electronic devices.

[0063] Figure 5 It is along Figure 1 A cross-sectional view taken along line II'. Figure 6 It is magnified Figure 5 Cross-sectional view of area A. Figure 7 It shows Figure 1 A three-dimensional diagram of an embodiment of a shape retaining portion included in a display device. Figure 8 It is magnified Figure 7 Stereoscopic image of area B. Figure 9 It shows Figure 1 A bottom view of a display device showing a state in which a display panel, a shape retaining portion, and a circuit board are combined.

[0064] Reference Figure 5 The shape-maintaining portion SP, the cover plate CP, the display panel PA, the adhesive layer AL, and the window WN may be disposed on the circuit board CB. Furthermore, the circuit board CB, the shape-maintaining portion SP, the cover plate CP, the display panel PA, and the adhesive layer AL may be accommodated in the window WN.

[0065] The shape maintaining portion SP may include a first surface S1 adjacent to the display portion DP of the display panel PA and a second surface S2 adjacent to the circuit board CB. For example, the first surface S1 may be an upper surface of the shape maintaining portion SP, and the second surface S2 may be a lower surface of the shape maintaining portion SP.

[0066] Reference Figure 5 and Figure 6 The first surface S1 may include a center portion CS and an edge portion ES. The edge portion ES may surround the center portion CS in a plane. In one embodiment, the center portion CS may have a shape that is convex and bent in the second direction DR2 in cross section. The edge portion ES may have a flat shape in cross section. For example, the edge portion ES may extend along the third direction DR3. The center portion CS is convex and bent, and the edge portion ES is flat, thereby facilitating the manufacture of the shape-retaining portion SP.

[0067] Reference Figure 8The second surface S2 may include an overlapping portion OP and a non-overlapping portion NOP. The overlapping portion OP may overlap with the circuit board CB in a planar manner. The non-overlapping portion NOP may not overlap with the circuit board CB in a planar manner. The overlapping portion OP and the non-overlapping portion NOP may each be flat. A step ST may be defined in cross section between the overlapping portion OP and the non-overlapping portion NOP. In one embodiment, the non-overlapping portion NOP may protrude in the first direction DR1 relative to the overlapping portion OP. The overlapping portion OP may be recessed in the second direction DR2 relative to the non-overlapping portion NOP.

[0068] Reference Figure 9 In one embodiment, when the shape-retaining portion SP and the circuit board CB are combined, the circuit board CB can be placed on the overlapping portion OP. In this case, the non-overlapping portion NOP can surround the side surfaces of the circuit board CB. As a result, the circuit board CB can be placed flat on the second surface S2 of the shape-retaining portion SP. The shape-retaining portion SP can maintain the shape of the circuit board CB.

[0069] Reference Figure 7 The edge ED of the shape-retaining portion SP may include a curved portion CE and a straight portion SE. The curved portion CE may extend in a manner having a curvature. For example, the curved portion CE may extend in a circular shape with a constant curvature on a plane. The straight portion SE may extend in a straight line on a plane. The curved portion CE and the straight portion SE may be connected to each other. Thus, the shape-retaining portion SP may have a straight shape in a portion on a plane and a circular shape in the remaining portion excluding the portion.

[0070] Reference Figure 6 and Figure 9 , the straight portion SE may correspond to the position where the bent portion BP bends. The bent portion BP may bend at the straight portion SE. That is, the bent portion BP may cover the straight portion SE while bending. The straight portion SE is arranged in the middle of the bent portion BP and the bent portion BP connects the display portion DP and the circuit board CB. In one embodiment, the edge ED of the shape-retaining portion SP arranged between the display portion DP and the circuit board CB may include the straight portion SE instead of a shape having a curvature as a whole. Thus, the shape-retaining portion SP does not exert an impact on the bent portion BP and does not interfere with the bending of the bent portion BP.

[0071] The circuit board CB may be disposed below the shape-maintaining portion SP, and the display portion DP of the display panel PA may be disposed on the shape-maintaining portion SP. The circuit board CB may be spaced apart from the display portion DP in the first direction DR1, and the circuit board CB and the bent portion BP of the display panel PA may be connected to each other via the shape-maintaining portion SP.

[0072] For example, the shape-retaining portion SP may include plastic. In this case, the shape-retaining portion SP can be manufactured by an injection molding process. As another example, the shape-retaining portion SP may include metal. In this case, the shape-retaining portion SP can be manufactured by computer numerical control (CNC) processing or a die-casting process. As another example, the shape-retaining portion SP may include rubber or silicone. In this case, the shape-retaining portion SP can be manufactured by a compression molding process. However, the present invention is not limited thereto, and the shape-retaining portion SP may include a variety of substances depending on the purpose of the shape-retaining portion SP, etc., and may be manufactured by a variety of processes.

[0073] In one embodiment, the display portion DP can be arranged along the outline of the first surface S1 of the shape-retaining portion SP, and the circuit board CB can be arranged along the outline of the second surface S2 of the shape-retaining portion SP. Specifically, the display portion DP can be arranged along the outline of the center portion CS of the first surface S1, and the circuit board CB can be arranged along the outline of the overlapping portion OP of the second surface S2. That is, the display portion DP can be arranged to convexly and bend in the second direction DR2, while the circuit board CB can be arranged flat.

[0074] If the circuit board CB bends, the components arranged on it may become damaged, fall off, or be incorrectly attached. In this case, because the shape-retaining portion SP maintains the flat shape of the circuit board CB, the circuit board CB can be securely attached to the shape-retaining portion SP. This reduces the risk of problems caused by bending the circuit board CB. Furthermore, the shape-retaining portion SP serves as a guide during assembly of the circuit board CB.

[0075] The cover plate CP may also be arranged along the contour of the first surface S1 of the shape-retaining portion SP, and the adhesive layer AL may be arranged along the contour of the display portion DP. Specifically, the center portion CS of the first surface S1 of the shape-retaining portion SP, the cover plate CP, the display portion DP of the display panel PA, and the adhesive layer AL may each have a cross-sectional shape that is convex and bent in the second direction DR2, such that the closer the edge is to the center, the further away from the circuit board CB. The display portion DP of the display panel PA may be bonded to the bent inner surface of the window WN via the adhesive layer AL.

[0076] According to one embodiment of the present invention, the display device DD may include a shape-preserving portion SP, comprising a first surface S1 and a second surface S2 having different cross-sectional shapes. The first surface S1 may include a central portion CS that is convexly bent in the second direction DR2, and the second surface S2 may include a flat overlapping portion OP on which the circuit board CB is disposed. This allows the display panel PA to be configured to conform to the shape of the window WN, while maintaining the shape of the circuit board CB, thereby preventing damage to components disposed on the circuit board CB.

[0077] Furthermore, since the shape-retaining portion SP includes the linear portion SE extending in a linear shape, interference with the curvature of the display panel PA can be prevented. Furthermore, since the first surface S1 of the shape-retaining portion SP includes the flat edge portion ES, the shape-retaining portion SP can be easily manufactured.

[0078] Figure 10 and Figure 11 It shows Figure 1 A perspective view of another embodiment of a shape retaining portion included in a display device. For example, Figure 10 It may be a perspective view showing the planar shape of the first surface S1 of the shape retaining portion SP'. Figure 11 1 is a perspective view showing the planar shape of the second surface S2 of the shape-retaining portion SP'.

[0079] Reference Figure 10 and Figure 11 The shape retaining portion SP' described above is similar to the shape of the second surface S2. Figures 7 to 9 The shape-retaining portions SP described above are substantially the same or similar.

[0080] Below, with reference Figures 7 to 9 The overlapping contents of the shape retaining portion SP described above will be omitted or simplified.

[0081] Reference Figure 10and Figure 11 The edge ED of the shape retaining portion SP' may include a curved portion CE and a straight portion SE. The curved portion CE may extend in a circular shape on a plane. The straight portion SE may be connected to the curved portion CE and extend straight on a plane.

[0082] The shape maintaining portion SP' may include a portion corresponding to the display portion (eg, Figure 5 The first surface S1 adjacent to the display portion DP and the circuit board (eg, Figure 5 For example, the first surface S1 may be the upper surface of the shape-maintaining portion SP', and the second surface S2 may be the lower surface of the shape-maintaining portion SP'.

[0083] The second surface S2 may include an overlapping portion OP and a non-overlapping portion NOP. The overlapping portion OP may overlap with the circuit board in a planar manner, and the non-overlapping portion NOP may not overlap with the circuit board in a planar manner. In one embodiment, the non-overlapping portion NOP may protrude in the first direction DR1 compared to the overlapping portion OP.

[0084] The circuit board can be arranged on the overlapping portion OP. In one embodiment, the non-overlapping portion NOP can surround at least a portion of a side surface of the circuit board. Specifically, the non-overlapping portion NOP can surround a portion of the side surface of the circuit board, but may not surround another portion of the side surface of the circuit board. For example, the non-overlapping portion NOP may not surround the side surface of the circuit board CB adjacent to the straight portion SE. Thus, on the second surface S2, the overlapping portion OP can include an area adjacent to the straight portion SE.

[0085] That is, the plane area of ​​the overlapping portion OP of the shape maintaining portion SP' can be larger than that of the reference portion SP'. Figures 7 to 9 The plane area of ​​the overlapping portion OP of the shape maintaining portion SP is relatively larger, and the plane area of ​​the non-overlapping portion NOP of the shape maintaining portion SP' can be larger than that of the reference Figures 7 to 9 The non-overlapping portion NOP of the shape-maintaining portion SP has a relatively smaller plane area. However, the present invention is not limited thereto, and the shapes and areas of the overlapping portion OP and the non-overlapping portion NOP may be varied in various ways.

[0086] Figure 12 It shows Figure 11 Another example of a stereogram. For example, Figure 12 It may be a perspective view showing another example of the planar shape of the second surface S2 of the shape maintaining portion SP'.

[0087] Below, with reference Figure 10 and Figure 11 The repeated description of the shape retaining portion SP' will be omitted or simplified.

[0088] Reference Figure 12 The second surface S2 of the shape maintaining portion SP′ may include the overlapping portion OP and the non-overlapping portion NOP.

[0089] In one embodiment, the shape-retaining portion SP' may include a first shape-retaining portion SP1 and a second shape-retaining portion SP2. The first shape-retaining portion SP1 and the second shape-retaining portion SP2 may be made of different materials. For example, the first shape-retaining portion SP1 may be made of plastic, and the second shape-retaining portion SP2 may be made of copper (Cu), but the present invention is not limited to this. Furthermore, in this case, the shape-retaining portion SP' may be manufactured through an insert molding process, but the present invention is not limited to this.

[0090] The second shape-retaining portion SP2 may be disposed on the first shape-retaining portion SP1. Specifically, the second shape-retaining portion SP2 may extend from the first shape-retaining portion SP1 in the first direction DR1. In the shape-retaining portion SP', the first shape-retaining portion SP1 may define the non-overlapping portion NOP, and the second shape-retaining portion SP2 may define the overlapping portion OP.

[0091] Figure 13 is a cross-sectional view showing a display device according to another embodiment of the present invention. Figure 13 Can be used with Figure 5 The cross-sectional view corresponds to .

[0092] Reference Figure 13 The display device DD' described above can be similar to the one shown in FIG. 1 except for the shapes of the shape retaining portion SP, the cover plate CP, the display panel PA, and the adhesive layer AL. Figures 1 to 9 The display devices DD described are substantially the same or similar.

[0093] Below, with reference Figures 1 to 9 Repeated descriptions of the display device DD will be omitted or simplified.

[0094] Reference Figure 13 The display device DD′ may include a window WN, the adhesive layer AL, the display panel PA, the cover plate CP, the shape maintaining portion SP, and a circuit board CB.

[0095] The shape maintaining portion SP, the cover panel CP, the display panel PA, the adhesive layer AL, and the window WN may be sequentially disposed on the circuit board CB. The display panel PA may include a display portion DP capable of displaying an image and a bent portion BP connected to the circuit board CB.

[0096] The shape maintaining portion SP may include a first surface S1 adjacent to the display portion DP of the display panel PA and a second surface S2 adjacent to the circuit board CB. For example, the first surface S1 may be an upper surface of the shape maintaining portion SP, and the second surface S2 may be a lower surface of the shape maintaining portion SP.

[0097] The first surface S1 may include a center portion CS and an edge portion ES surrounding the center portion CS. The center portion CS may have a cross-sectional shape that is convex and bent in the second direction DR2, and the edge portion ES may have a flat cross-sectional shape. In one embodiment, the edge portion ES may be inclined.

[0098] The cover plate CP and the display portion DP of the display panel PA can be arranged along the contour of the first surface S1 of the shape-preserving portion SP. The adhesive layer AL can be arranged along the contour of the display portion DP. Specifically, the edges of the cover plate CP, the display portion DP, and the adhesive layer AL are inclined and have convex, bent cross-sectional shapes, such that the closer the edge is to the center, the further away from the circuit board CB. Because the edges of the display portion DP are inclined, images can also be displayed on the side of the display device DD'.
