Description

[Technical Field]

[0001] The following embodiments relate to stretchable Organic Light-Emitting Diode (OLED) technology. [Background technology]

[0002] In recent years, the display industry has focused on producing displays with improved form factors, such as flexible and foldable displays.

[0003] Stretchable organic light-emitting diodes (OLEDs) are a display platform with the ultimate form factor. Conventional OLEDs have a structure that includes interconnects that connect isolated regions and contract / extend horizontally.

[0004] However, conventional stretchable organic light-emitting diodes have a limitation in that the interconnector portion stretches horizontally when extended from a contracted state, resulting in a space and a reduced area ratio.

[0005] This has created a need for technology to overcome the limitation of the area ratio decreasing when the material is stretched or contracted. Summary of the Invention [Problem to be solved by the invention]

[0006] One embodiment proposes a stretchable organic light-emitting diode with a structure including a hidden light-emitting region that stretches in the vertical direction to achieve a significantly improved light-emitting area ratio compared to diodes with conventional structures and to have mechanical stability against external shocks.

[0007] Furthermore, in order to achieve the objective of minimizing the deformation rate of the isolated region, one embodiment proposes a stretchable organic light-emitting diode that uses a stretchable base layer and a fixing region formed thereon as a stretchable wafer, and realizes a structure in which the isolated region of the organic light-emitting diode layer is aligned and bonded onto the fixing region that maintains a fixed shape.

[0008] In addition, one embodiment proposes a stretchable organic light-emitting diode that can be stretched in four or more directions on a horizontal plane to overcome the limitation of conventional structures that extend in two axes, in that the diode has curved edges, and to achieve the goal of realizing edges that are uniformly shaped and close to straight, rather than curved.

[0009] The technical problem to be solved by the present invention should not be limited to the above, but may be variously expanded within the scope of the technical idea and scope of the present invention. [Means for solving the problem]

[0010] According to one embodiment, the stretchable organic light emitting diode may include a plurality of isolated regions arranged in a vertically protruding state, and a hidden light emitting region connecting the isolated regions to each other and stretching in the vertical direction.

[0011] According to one aspect, the hidden light-emitting region may be characterized in that when the stretchable organic light-emitting diode contracts horizontally, the hidden light-emitting region buckles so as to be hidden within the space between the isolated regions and not appear on the surface of the isolated regions.

[0012] According to another aspect, the stretchable organic light emitting diode may be characterized in that, when extended in the horizontal direction, the hidden light emitting region is exposed between the isolated regions, thereby ensuring a light emitting area.

[0013] According to another aspect, the stretchable organic light emitting diode may be characterized in that it can be extended in the horizontal direction when tension is applied to it in four or more axes in a horizontal plane.

[0014] According to another aspect, the stretchable organic light emitting diode may further include a stretchable base layer having a plurality of arranged fixing regions formed thereon and protruding in the vertical direction, and the isolated regions may be aligned and bonded to the fixing regions.

[0015] According to another aspect, the fixing region may be formed of a different material from the base layer so that when a tensile force is applied to the base layer in a horizontal direction, the fixing region does not expand in the horizontal direction but maintains a fixed shape.

[0016] According to another aspect, when the stretchable organic light emitting diode is extended in the horizontal direction, the hidden light emitting region is exposed between the isolated regions in response to the horizontal extension of a region of the base layer in which the fixing region is not formed.

[0017] According to another aspect, the stretchable organic light emitting diode may be characterized in that the stretchable organic light emitting diode is extensible in the horizontal direction by applying the tensile force in four or more axes in a horizontal plane to an area of ​​the base layer where the fixing area is not formed, causing the area of ​​the base layer where the fixing area is not formed to extend in the horizontal direction.

[0018] According to another aspect, the hidden light-emitting region may be characterized in that a region between diagonally adjacent isolated regions among the isolated regions has an empty structure.

[0019] According to another aspect, the stretchable organic light-emitting diode may further include at least one electrode electrically connected to the isolated region and the hidden light-emitting region.

[0020] According to yet another aspect, the isolated region and the hidden light-emitting region may be formed collectively from the same material.

[0021] According to one embodiment, the stretchable organic light-emitting diode may include a plurality of isolated regions arranged in a vertically protruding state, and hidden light-emitting regions that buckle so as to be hidden within spaces between the isolated regions and not appear on the surfaces of the isolated regions when the stretchable organic light-emitting diode is contracted in a horizontal direction with the isolated regions connected to one another, and that are exposed between the isolated regions when the stretchable organic light-emitting diode is extended in the horizontal direction.

[0022] According to one embodiment, a method for manufacturing a stretchable organic light-emitting diode may include forming an organic light-emitting diode layer using a stretchable material, the organic light-emitting diode layer including a plurality of isolated regions arranged in a vertically protruding state and a hidden light-emitting region connecting the isolated regions; preparing a stretchable base layer having a plurality of fixing regions arranged in a vertically protruding state; applying a tensile force to the base layer to extend the base layer horizontally, and bonding the isolated regions onto the fixing regions; and removing the tensile force applied to the base layer to contract the base layer and buckle the hidden light-emitting regions in the vertical direction.

[0023] According to one aspect, the step of buckling the hidden light-emitting region in the vertical direction may be characterized as a step of buckling the hidden light-emitting region in the vertical direction so that when the base layer contracts in the horizontal direction, the hidden light-emitting region does not appear on the surface of the isolated region but is hidden within the space between the isolated regions.

[0024] According to another aspect, the fixing region may be formed of a different material from the base layer so as to maintain a fixed shape without expanding in the horizontal direction when the tensile force is applied to the base layer.

[0025] According to another aspect, the step of preparing the base layer may include forming the fixing region from a material that is strong against the tensile force, and forming the base layer that adheres to the fixing region from a material that has elasticity.

[0026] According to another aspect, the step of bonding the isolated region may include a step of extending an area of ​​the base layer in which the fixed region is not formed in the horizontal direction and bonding the isolated region in an aligned state on the fixed region.

[0027] According to another aspect, the step of joining the isolated region to the fixed region in an aligned state may include applying the tensile force in four or more axes on a horizontal plane to the region of the base layer where the fixed region is not formed, thereby extending the region of the base layer where the fixed region is not formed in the horizontal direction.

[0028] According to another aspect, the step of forming the organic light emitting diode layer may be characterized in that the isolated region and the hidden light emitting region are formed at the same time using the same material.

[0029] According to yet another aspect, the step of forming the organic light emitting diode layer may include forming a region corresponding to a space between diagonally adjacent isolated regions among the isolated regions on the hidden light emitting region as an open structure. [Effects of the Invention]

[0031] In addition, one embodiment proposes a stretchable organic light-emitting diode that uses a stretchable base layer and a fixing region formed thereon as a stretchable wafer, and realizes a structure in which an isolated region of an organic light-emitting diode layer is aligned and bonded to the fixing region that maintains a fixed shape, thereby achieving the effect of minimizing the deformation rate of the isolated region.

[0032] Furthermore, one embodiment proposes a stretchable organic light-emitting diode that can be stretched in four or more directions on a horizontal plane, thereby overcoming the limitation of conventional diodes that stretch in two directions, which have curved edges, and achieving the effect of realizing edges that are uniformly shaped and close to straight, rather than curved.

DETAILED DESCRIPTION OF THE INVENTION

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention should not be limited or restricted by the embodiments. The same reference numerals shown in the drawings indicate the same elements.

[0036] Furthermore, the terminology used herein is merely used to appropriately describe preferred embodiments of the present invention and may vary depending on the audience, the operator's intention, or the practices of the field to which the present invention pertains. Therefore, such terms should be defined based on the overall content of this specification. For example, the singular forms described herein also include the plural forms unless otherwise specified in the context. Furthermore, the terms "comprise" and / or "comprising" used herein do not exclude the presence or addition of one or more other components, steps, operations, and / or elements among the described components, steps, operations, and / or elements.

[0037] It should also be understood that the various embodiments of the present invention, although different from one another, are not necessarily mutually exclusive. For example, a particular shape, structure, and characteristic described herein may be implemented in other embodiments without departing from the spirit and scope of the present invention. It should also be understood that within the scope of each of the presented embodiments, the position, arrangement, or configuration of individual components may be changed without departing from the spirit and scope of the present invention.

[0038] In the following description, the "horizontal direction" means a direction perpendicular to the direction of gravity, and the "vertical direction" means a direction perpendicular to the "horizontal direction."

[0039] 1a to 1c are diagrams illustrating a stretchable organic light-emitting diode according to one embodiment, and 2a to 2c are diagrams illustrating the advantages of the stretchable organic light-emitting diode according to one embodiment. More specifically, FIG. 1a is a diagram illustrating the stretchable organic light-emitting diode in a contracted state, FIG. 1b is a diagram illustrating the stretchable organic light-emitting diode in a partially extended state, and FIG. 1c is a diagram illustrating the stretchable organic light-emitting diode in a fully extended state.

[0040] A stretchable organic light emitting diode 100 according to one embodiment may include a base layer 110, an organic light emitting diode layer 120, and at least one electrode (not shown).

[0041] The base layer 110 may be formed of an elastic material (e.g., Ecoflex (registered trademark) 0020), and a plurality of fixed regions 111 may be formed on the base layer 110 and arranged in a vertically protruding state.

[0042] In this case, the fixing region 111 may be formed of a different material (e.g., PDMS) from the base layer 110 so that the fixing region 111 maintains a fixed shape without expanding horizontally when a horizontal tensile force is applied to the base layer 110. That is, the base layer 110 on which the fixing region 111 is formed may be made of a different type of elastic polymer.

[0043] Therefore, the horizontal extension of the base layer 100 may mean that the region of the base layer 100 where the fixing region 111 is not formed is extended horizontally, and the horizontal extension of the stretchable organic light-emitting diode 100 is made possible by the horizontal extension of the region of the base layer 100 where the fixing region 111 is not formed.

[0044] The organic light-emitting diode layer 120 may include a plurality of isolated regions 121 arranged in a vertically protruding state, and a hidden light-emitting region 122 that connects the isolated regions 121 to each other and stretches in the vertical direction. Hereinafter, the hidden light-emitting region 122 may be referred to as an interconnector or a stretchable interconnector, since it also plays a role in connecting the isolated regions 121 to each other.

[0045] The isolated region 121 and the hidden light-emitting region 122 may be formed together from the same material, but are not limited or restricted thereto.

[0046] The isolated region 121 may be aligned and bonded to the fixed region 111. This allows the isolated region 121 to maintain its fixed shape without extending even if the stretchable organic light-emitting diode 100 extends in the horizontal direction, thanks to the fixed region 111 that maintains its fixed shape.

[0047] Here, the fact that the hidden light-emitting region 122 stretches vertically means that when the stretchable organic light-emitting diode 100 contracts horizontally, the hidden light-emitting region 122 buckles vertically so that it is hidden in the space between the isolated regions 121 and does not appear on the surface of the isolated regions 121, as shown in the enlarged portion of FIG. 1a, and then when the stretchable organic light-emitting diode 100 extends horizontally, the hidden light-emitting region 122 moves vertically and is exposed from between the isolated regions 121, as shown in the enlarged portions of FIGS. 1b and 1c.

[0048] In this way, since hidden light-emitting region 122 expands and contracts in the vertical direction as shown in Fig. 2a, it can have an area ratio that is significantly improved compared to the area ratio of existing structures that expand and contract in the horizontal direction as shown in Fig. 2b, as can be proven by Fig. 2c. Having an improved area ratio compared to existing structures means that when fabricated to the same size as existing structures, it has an increased light-emitting area compared to existing structures (light-emitting area is guaranteed).

[0049] As described above, when the stretchable organic light-emitting diode 100 extends horizontally, only the areas of the base layer 110 where the fixing regions 111 are not formed extend horizontally, and therefore the hidden light-emitting areas 122 are exposed between the isolated areas 121 in response to the horizontal extension of only the areas of the base layer 110 where the fixing regions 111 are not formed.

[0050] In this case, the hidden light-emitting region 122 may have an empty structure in the region 122-1 corresponding to the space between the diagonally adjacent isolated regions 121 among the isolated regions 121. This is to ensure that the hidden light-emitting region 122 is not exposed on the surface of the isolated regions 121 but is entirely hidden within the space between the isolated regions 121 when the stretchable organic light-emitting diode 100 contracts in the horizontal direction.

[0051] The horizontal extension described above may be achieved by applying tensile forces in four or more axes on a horizontal plane. That is, the horizontal extension described above means extension in four or more axes on a horizontal plane.

[0052] Although not shown in the figure, the stretchable organic light-emitting diode 100 may further include at least one electrode (not shown) that is electrically connected to the isolated region 121 and the hidden light-emitting region 122.

[0053] The stretchable organic light-emitting diode 100 according to the embodiment described above includes a hidden light-emitting region 122 that stretches vertically, thereby achieving a significantly improved light-emitting area ratio compared to diodes with conventional structures, and the hidden light-emitting region 122 provides mechanical stability against external impacts.

[0054] In addition, the stretchable organic light-emitting diode 100 according to the embodiment described above uses the stretchable base layer 100 and the fixing region 111 formed thereon as a stretchable wafer, and realizes a structure in which the isolated region 121 of the organic light-emitting diode layer 120 is aligned and bonded to the fixing region 111 that maintains a fixed shape, thereby achieving the effect of minimizing the deformation rate of the isolated region 121.

[0055] Furthermore, the stretchable organic light-emitting diode 100 according to the embodiment described above can be extended in four or more directions on a horizontal plane, thereby overcoming the limitation of conventional diodes that extend in two directions, which have curved edges, and achieving the effect of realizing edges with a uniform shape that is close to a straight line without any curves.

[0056] A method for fabricating the stretchable organic light-emitting diode 100 having the above structure will now be described.

[0057] 3 is a flowchart illustrating a method for fabricating a stretchable organic light-emitting diode according to one embodiment, and FIGS. 4a to 4h are diagrams illustrating detailed processes of step 310 in FIG. 3, FIGS. 5a to 5d are diagrams illustrating detailed processes of step 320 in FIG. 3, and FIGS. 6a to 6c are diagrams illustrating detailed processes of steps 330 to 340 in FIG. 3. The fabrication method for a stretchable organic light-emitting diode described below is assumed to be performed by an automated and mechanized fabrication system, and the result fabricated by performing steps 310 to 340 may be the stretchable organic light-emitting diode 100 having the structure described above.

[0058] In step S310, the fabrication system may form the organic light emitting diode layer 120 using a stretchable material.

[0059] Here, the organic light emitting diode layer 120 may include a plurality of isolated regions 121 arranged in a state of protruding in the vertical direction, and hidden light emitting regions 122 connecting the isolated regions 121 .

[0060] The isolated region 121 and the hidden light-emitting region 122 may be formed collectively using the same material, and the hidden light-emitting region 122 may have an empty structure in the region 122-1 corresponding to the space between the diagonally adjacent isolated regions 121 among the isolated regions 121.

[0061] Step 310 may be performed by the processes shown in Figures 4a to 4h. For example, the manufacturing system may form the organic light emitting diode layer 120 by coating polyimide on a wafer to a thickness of 1 μm at 8000 rpm, 30 seconds, and 3 acl as shown in Figure 4a, sputtering aluminum on the polyimide to a thickness of 200 nm as shown in Figure 4b, coating photoresist (PR) on the aluminum as shown in Figure 4c, patterning the photoresist using a mask as shown in Figure 4d, performing aluminum wet etching as shown in Figure 4e, performing photoresist stripping as shown in Figure 4f, performing dry etching of a portion of the polyimide to a certain depth to form a polyimide pattern as shown in Figure 4g, and depositing an organic light emitting diode on the polyimide pattern and performing laser lift-off as shown in Figure 4h.

[0062] At step 320, the fabrication system may provide a stretchable base layer 110 having a plurality of vertically protruding, arrayed fastening regions 111 formed thereon.

[0063] In this case, the anchoring regions 111 may be arranged at intervals narrower than the isolation regions 121 of the organic light emitting diode layer 120. Therefore, when the region of the base layer 110 where the anchoring regions 111 are not formed extends in the horizontal direction, the anchoring regions 111 are arranged at the same intervals as the isolation regions 121. This is because, in step 330 described below, the region of the base layer 110 where the anchoring regions 111 are not formed extends in the horizontal direction, so that the anchoring regions 111 are aligned with the isolation regions 121.

[0064] The fixed region 111 may be formed of a different material from the base layer 110 so that when a horizontal tensile force is applied to the base layer 110, the fixed region 111 does not expand horizontally but maintains a fixed shape.

[0065] Thus, step 320 may include a first step of forming the anchoring region 111 from a material that is strong against tensile force, and a second step of forming the base layer 110 that is joined to the anchoring region 111 from a material that has elasticity.

[0066] Step 320 may be performed through the steps shown in Figures 5a to 5d. For example, the manufacturing system may prepare the base layer 110 on which the fixing region 111 is formed by forming PDMS on an aluminum mold having a pattern formed on its surface as shown in Figure 5a, using a glass doctor blade on the surface of the aluminum mold on which the PDMS is formed to form the fixing region 111 as shown in Figure 5b, forming the base layer 110 on the fixing region 111 using Ecoflex (registered trademark) 0020 as shown in Figure 5c, and separating the base layer 110 with the fixing region 111 bonded thereto from the aluminum mold using a spacer as shown in Figure 5d.

[0067] In step 330, the fabrication system may bond the isolated region 121 onto the fixed region 111 while applying a tensile force to the base layer 110 to extend the base layer 110 in the horizontal direction.

[0068] Specifically, in step 330, the manufacturing system may bond the base layer 110 in a state where the area where the fixed area 111 is not formed is extended horizontally and the isolated area 121 is aligned on the fixed area 110.

[0069] In this case, the horizontal extension of the area of ​​the base layer 110 where the fixed area 111 is not formed may be achieved by applying tensile forces in four or more axes on a horizontal plane to the area of ​​the base layer 110 where the fixed area 111 is not formed.

[0070] In step S340, the manufacturing system may remove the tension applied to the base layer 110 to cause the base layer 110 to contract and buckle the hidden light-emitting areas 122 in the vertical direction.

[0071] More specifically, in step S340, the manufacturing system may buckle the hidden light-emitting areas 122 vertically so that when the base layer 110 shrinks horizontally, the hidden light-emitting areas 122 are hidden within the spaces between the isolated areas 121 rather than appearing on the surface of the isolated areas 121.

[0072] Therefore, when the fabricated stretchable organic light-emitting diode 100 contracts horizontally, the hidden light-emitting region 122 does not appear on the surface of the isolated region 121 but is hidden in the space between the isolated regions 121, and when the stretchable organic light-emitting diode 100 extends horizontally, the hidden light-emitting region 122 moves vertically and is exposed from between the isolated regions 121.

[0073] Steps 330 to 340 may be performed according to the process shown in Figures 6a to 6c.

[0074] For example, the manufacturing system may include the steps of applying a tensile force on four or more axes in a horizontal plane to the base layer 110, and then applying an adhesive to the fixed region 111, as shown in FIG. 6a; selectively bonding the isolated region 121 onto the fixed region 111 with the adhesive, as shown in FIG. 6b; and removing the tensile force applied to the base layer 110 to contract the base layer 110 and vertically buckle the hidden light-emitting region 122, as shown in FIG. 6c.

[0075] Although the embodiments have been described above based on limited examples and drawings, those skilled in the art will appreciate that various modifications and variations may be made from the above description. For example, the described techniques may be performed in an order different from that described, and / or the described system, structure, device, circuit, or other element may be coupled or combined in a manner different from that described, or may be substituted or replaced by other elements or equivalents, and still achieve suitable results.

[0076] Therefore, different embodiments are within the scope of the appended claims, provided that they are equivalent to the claims. [Explanation of symbols]
