[0064] like Figure 2 As shown, the display panel 10 may include a display element 150 capable of realizing or emitting (or configured to realize or emit) visible light to provide visible light to a user. The display element 150 may include one or more suitable types or kinds, and in one or more embodiments, the case where the display element 150 is an organic light-emitting element is described as an example.

[0069] The first electrode 151 may be used as or serve as an anode, and the second electrode 152 may be used as or serve as a cathode. The polarity order of the first electrode 151 and the second electrode 152 may be reversed. If (e.g., when) the first electrode 151 is used as or serves as an anode, the first electrode 151 may include ITO, IZO, ZnO, In2O3, etc., having a high work function. In one or more embodiments, depending on the purpose and design conditions, the first electrode 151 may further include a reflective (e.g., substantially reflective) film, including silver (Ag), magnesium (Mg), aluminum (Al), platinum (Pt), palladium (Pd), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), ytterbium (Yb), calcium (Ca), etc.

[0071] Intermediate layer 153 may include at least an organic emitting layer. In one or more embodiments, in addition to the organic emitting layer, intermediate layer 153 may selectively include at least one selected from a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer. Visible light can be generated from intermediate layer 153 (e.g., the organic emitting layer of intermediate layer 153) when a voltage is applied to the first electrode 151 and the second electrode 152.

[0072] The encapsulation component 170 may be on the display element 150 to protect the display element 150. The encapsulation component 170 may protect the display element 150 from external impacts (or reduce the degree or occurrence of external impacts on the display element 150) and prevent the penetration of external substances and / or moisture (or reduce the degree or occurrence of external substances and / or moisture penetration).

[0073] The encapsulation member 170 may be one or more suitable types or kinds.

The source electrode 137' and the drain electrode 138' may be formed or provided for a set or specific area to contact the active layer 133'.

[0082] A passivation layer 140' may be formed or provided to cover the source electrode 137' and the drain electrode 138'. A separate insulating (e.g., electrically insulating) film may also be formed or provided on the passivation layer 140' to planarize the thin-film transistor.

[0090] Figure 4 For illustrative purposes only Figure 1 A cross-sectional view of an example heat dissipation component, and Figure 5 For illustrative purposes only Figure 1 A plan view of an example heat dissipation component.

[0091] refer to Figure 4 The heat dissipation component 30 may include a base plate 310, a flexible tube 330, a cover portion 340, and a filling layer 350.

[0092] For example, a flexible tube 330 formed or provided to allow at least fluid (e.g., fluid and / or solid) to move may be in a groove 320 in one surface of the base plate 310, and a cover portion 340 may be provided between the base plate 310 and the display panel 10 (see example). Figure 1 The filling layer 350 is located between the base plate 310 and the cover portion 340.

[0093] In one or more embodiments, a stop 360 may be further arranged or provided that projects from the base plate 310 toward the cover portion 340.

[0094] This will be described in more detail in this article.

[0095] The base plate 310 may have one or more suitable shapes. For example, the base plate 310 may have a plate shape (e.g., a substantially plate shape) corresponding to the plate shape of the display panel 10, and, for example, the base plate 310 may have a plate shape (e.g., a substantially plate shape) having an area corresponding to the area of ​​the display panel 10. As another example, the base plate 310 may be formed or provided to be smaller than the display panel 10, or as another example, it may be formed or provided to be larger than the display panel 10.

[0096] As an example, the base plate 310 may have (in Figure 4 The thickness in the Z-axis direction and the width and length in the direction perpendicular to (e.g., substantially perpendicular to) the thickness direction of the base plate 310, and the width and length may have values ​​at least greater than the thickness.

[0097] In one or more embodiments, as an example, the base plate 310 may have a polygonal (e.g., substantially polygonal) planar shape, and, for example, the base plate 310 may have a rectangular (e.g., substantially rectangular) planar shape.

[0098] The material of the substrate 310 can vary. For example, the substrate 310 may include a flexible material to facilitate easy bonding with the display panel 10, such as lamination. For example, the substrate 310 may include at least a polymer and / or a metal. In one or more embodiments, the substrate 310 may include a material with relatively high thermal conductivity to effectively absorb heat from the display panel 10.

[0099] The groove 320 may be in one surface of the base plate 310. The groove 320 may be a flow path through which the coolant flows.

[0100] The groove 320 may be in one surface of the base plate 310 to form or provide at least one path. For example, a closed loop may be formed or provided as a path. In one or more embodiments, the groove 320 may also form or provide multiple closed loops.

[0101] Additionally, the groove 320 may have a desired length and shape in one surface of the base plate 310 to control the length and area of ​​the flow path through which the coolant flows on one surface of the base plate 310.

[0102] The slot 320 can be arranged or provided as curved by changing its orientation at least once to have two or more regions spaced apart and / or separated (e.g., spaced apart or separated) in the width direction of the slot 320.

[0103] As an example, the groove 320 may have a structure in which it is formed as long in one direction (e.g., in a direction parallel to (e.g., substantially parallel to) one surface of the base plate 310), and then the process of changing its direction is repeated, and it is formed or provided as long at least once, for example, multiple times, in a direction parallel to (e.g., substantially parallel to) one surface of the base plate 310.

[0104] In one or more embodiments, the groove 320 may extend from a vertex of the base plate 310 along a surface adjacent to that vertex (e.g., ...). Figure 1The groove 320 can be formed or provided from one surface to the opposite surface of a vertex by rotating 180° toward the opposite vertex of the vertex before reaching the other surface adjacent to the vertex. Therefore, the groove 320 can be defined from one surface to the opposite surface of the first surface in one or more embodiments as described. The groove 320 can form or provide a closed loop.

[0105] The flexible tube 330 can be inserted into the groove 320, and the flexible tube 330 can be fixed to the groove 320 with packing.

[0106] The flexible tube 330 may be located in the groove 320 of the base plate 310. Accordingly, as an example, the flexible tube 330 may also be formed or provided along the groove 320. Figure 5 The closed loop shown.

[0107] A fluid (e.g., a coolant) may flow within the flexible tube 330. The coolant in the flexible tube 330 may absorb heat generated by the display panel 10 to reduce the temperature of the display panel 10. In one or more embodiments, the flexible tube 330 may be made of a material with relatively high thermal conductivity.

[0108] The fluid may include a coolant for heat dissipation, and the coolant may move within or through the internal space 331 of the flexible tube 330.

[0109] One or more suitable coolants may be arranged or supplied and flow in the flexible tube 330, which is a closed loop. For example, a coolant in gaseous or liquid form may be arranged or supplied.

[0110] As an example, a coolant comprising a mixture of two different phases (e.g., liquid and gas) may also be arranged or provided. If, for example, heat is generated in a set or specific area of ​​the display panel 10, the coolant in the flexible tube 330 overlapping the heat-generating portion of the display panel 10 can absorb the heat in the display panel 10, and the set or specific amount of liquid-phase coolant at the portion overlapping the heat-generating portion can be converted into gas-phase coolant, and thus the flow of coolant within the closed-loop flexible tube 330 can be accelerated, and the heat of the display panel 10 can be rapidly absorbed.

[0111] In one or more embodiments, coolant may flow into the internal space 331 of the flexible tube 330 to separate the coolant from the base plate 310, thereby reducing the problem of mutual influence and unwanted reactions between the coolant and the base plate 310.

[0112] In one or more embodiments, one or more suitable coolants can be selected by addressing the reaction between the base plate 310 and the coolant.

[0113] In one or more embodiments, in a structure in which fluid flows in a groove 320 between a base plate 310 and a cover portion 340, when coolant flows in the flexible tube 330, problems such as fluid leakage due to joint defects between the base plate 310 and the cover portion 340, blockage of the flow path through which coolant flows due to residual auxiliary materials (such as filler material for the joint between the base plate 310 and the cover portion 340), and fluid resistance problems depending on the quality of the machined surface of the groove 320 can be mitigated.

[0114] The flexible tube 330 may include a material with bending or flexibility properties to correspond to the shape of the groove 320 or the cover portion 340 having a curved shape, or to the shape of the groove 320 or the cover portion 340 having multiple bends. For example, the flexible tube 330 may include a polymeric material.

[0115] In addition, for example, the flexible tube 330 may include a silicon material.

[0116] The flexible tube 330 according to one or more embodiments can easily or appropriately implement multiple flow paths and can be arranged or provided to have a large contact area with the base plate 310 and the cover portion 340, and thus the flexible tube 330 can receive more heat generated from the display panel 10.

[0117] In one or more embodiments, the flexible tube 330 may be flexible, thus having one or more suitable shapes depending on the shape and height of the groove 320 and the degree of compression of the cover portion 340. Furthermore, multiple flow paths may be formed or provided with a single flexible tube 330.

[0118] The flexible tube 330 may at least define an internal space 331 through which fluid flows. As an example, the cross-section of the internal space 331 through which the fluid moves in the flexible tube 330 may have a curved shape. Due to factors such as the shape and height of the groove 320, the cross-section of the internal space 331 through which the fluid moves in the flexible tube 330 may have one or more suitable shapes, such as polygonal shapes.

[0119] The flexible tube 330 can be fixed between the groove 320 and the cover portion 340 by the filling layer 350.

[0120] In the case of flexible tube 330, coolant can be directly injected into flexible tube 330, and the injection port can be blocked again. Therefore, the difficulty of the coolant injection process is lower than that of the case where coolant flows between tank 320 and cover portion 340.

[0121] The cover portion 340 may be arranged or provided to cover the base plate 310 and the flexible tube 330 inserted into the groove 320.

[0122] The cover portion 340 can be attached to the base plate 310.

[0123] For example, the cover portion 340 and the base plate 310 can be bonded to each other using the filler of the filler layer 350. In one or more embodiments, the cover portion 340 and the base plate 310 can be bonded to each other using one or more suitable mechanical bonding methods and / or chemical bonding methods. Furthermore, the surface opposite to one surface of the base plate 310 to which the cover portion 340 is bonded can be bonded to the display panel 10. As an example, the cover portion 340 and the display panel 10 can be bonded to each other using a roll lamination process.

[0124] If, for example, the coolant flows in the tank 320 instead of inside the flexible tube 330, the entire product of the display device 1 may be defective even if, for example, the base plate 310 and the cover portion 340 are not fully or properly joined together, and the joining defect may occur only locally. For example, regardless of whether the base plate 310 and the cover portion 340 are made of substantially the same material or different materials, joining the base plate 310 and the cover portion 340 together may be difficult, and the cover portion 340 may warp.

[0125] In one or more embodiments, the heat dissipation member 30 will not be damaged even if (for example) the coolant flows inside the flexible tube 330 and the base plate 310 and the cover portion 340 are not fully or properly joined together, and a display device 1 of good quality can also be generated by the joint between the base plate 310 and the cover portion 340 (the degree of joint can maintain pressure on the flexible tube 330).

[0126] The material of the cover portion 340 may include one or more suitable materials, such as a flexible material, and, for example, the cover portion 340 may include a material substantially the same as the material of the base plate 310. As an example, the material of the cover portion 340 may include at least a polymer and / or a metal.

[0127] Except for the portion where the base plate 310 and the cover portion 340 are joined together by the filler layer 350, the base plate 310 and the cover portion 340 may be directly joined together. For the directly joined portion, if (for example, when) both the base plate 310 and the cover portion 340 (for example, both) comprise metal, the base plate 310 and the cover portion 340 may be joined together by spot welding, riveting, or the like.

[0128] In one or more embodiments, if (for example, when) both the base plate 310 and the cover portion 340 comprise polymer materials or comprise different materials such as polymers and metals, the base plate 310 and the cover portion 340 may be joined together by thermal fusion, ultrasonic fusion, or the like.

[0129] The filler layer 350 may be located between the base plate 310 and the cover portion 340. In one or more embodiments, the filler layer 350 may be arranged or provided as contacting at least one area of ​​the flexible tube 330.

[0130] For example, after the groove 320 of the base plate 310 is filled with filler, the filler may overflow from the groove 320 when the flexible tube 330 is placed in the groove 320. When the base plate 310 and the cover portion 340 are joined together, the overflowing filler may form or provide a filler layer 350, and the filler of the filler layer 350 may help the base plate 310 and the cover portion 340 to join together.

[0131] The filler layer 350 may contain a curable filler. As an example, the filler layer 350 may contain a material that is cured by heat and / or light.

[0132] After the groove 320 is filled with filler, the flexible tube 330 can be inserted into the groove 320, and then the filler can be cured, and the flexible tube 330 can be fixed to the groove 320 by the cured filler.

[0133] In one or more embodiments, the cover portion 340 may cover the filler overflowing from the groove 320 and the flexible tube 330, such that the cover portion 340 and the base plate 310 can be bonded to each other, and the filler can be re-cured. The cured filler may form or provide a filler layer 350 and attach the base plate 310 to the cover portion 340 to prevent (or reduce the degree or occurrence of the risk of damage to the heat dissipation component 30).

[0134] A filler layer 350, formed or provided by an adhesive filler, can bond the base plate 310, the cover portion 340, and the flexible tube 330 together to reduce or prevent coolant leakage problems caused by poor or weak bonding between the base plate 310 and the cover portion 340 in a structure that allows fluid to flow in the groove 320 between the base plate 310 and the cover portion 340. In one or more embodiments, if (e.g., when) coolant leaks due to defects in the flexible tube 330, the filler layer 350 can also prevent secondary coolant leakage (or reduce the extent or occurrence of secondary coolant leakage).

[0135] The filler layer 350 may include one or more suitable materials, including resin-based materials, or may include curable materials, such as light-curing resins and / or thermosetting resins.

[0136] In one or more embodiments, the base plate 310 may further include a stop 360. The stop 360 may have a protruding shape, for example, it may have a protruding shape toward the cover portion 340 in the thickness direction of the base plate 310.

[0137] The stop 360 may be formed or provided to be at least spaced apart from and / or separated from the slot 320 (e.g., spaced apart or separated). The stop 360 may be between multiple regions (e.g., two regions) that are spaced apart and / or separated (e.g., spaced apart or separated) in the width direction of the slot 320. For example, the stop 360 may be in adjacent slots 320 in the width direction of the slot 320 (e.g., Figure 4 Between two regions along the X-axis (in the X-axis direction).

[0138] For example, multiple stops 360 (e.g., such as...) Figure 4 The two stops shown can be located between a portion of the groove 320 extending along one surface of the base plate 310 and a portion of the groove 320 that overlaps with that portion in a vertical (e.g., substantially vertical) direction on one surface.

[0139] In one or more embodiments, the stop 360 may have an elongated structure, for example, in the longitudinal direction of the slot 320 (e.g., Figure 4 A structure that extends long in the Y-axis direction. For example, the stop 360 may also have a length that corresponds at least to the length of the groove 320 in one direction.

[0140] As an example, the stop 360 may be arranged or provided to engage with (or contact) the cover portion 340.

[0141] For example, at least one stop 360 may be attached to the cover portion 340 to maintain or provide a compressed state for the flexible tube 330 and to strengthen or reinforce the connection between the base plate 310 and the cover portion 340. In one or more embodiments, the stop 360 and the cover portion 340 may be joined together by one or more suitable methods such as welding, riveting, thermal fusion, ultrasonic fusion, etc.

[0142] For example, the stop 360 may protrude in the thickness direction of the base plate 310 to increase the area where the filler can contact the base plate 310 and the cover portion 340, thereby strengthening or enhancing the bond between the base plate 310 and the cover portion 340.

[0143] The stop 360 can prevent fluid leakage from the heat dissipation component 30 (or reduce the extent or occurrence of fluid leakage from the heat dissipation component 30) while being attached to the cover portion 340. As an example, the stop 360 can be spot-welded to the cover portion 340 to strengthen or enhance its attachment.

[0144] The degree of compression of the flexible tube 330 can be adjusted based on the presence or absence of the stop 360 and the height of the stop 360. Assuming that the grooves 320 have substantially the same depth, the lower the height of the stop 360, the greater the degree of compression of the flexible tube 330 can be.

[0145] Figure 6 For illustrative purposes only Figure 1A cross-sectional view of another example of a heat dissipation component. The heat dissipation component 40 may include a base plate 410 having a groove 420, a flexible tube 430 inserted into the groove 420, a cover portion 440 covering the base plate 410 and the flexible tube 430, and a filler layer 450 between the base plate 410 and the cover portion 440. In one or more embodiments, the flexible tube 430 may include an internal space 431.

[0146] A flexible tube 430, formed or provided to allow at least fluid (e.g., fluid and / or solid) to move, may be in a groove 420 in one surface of a base plate 410, and a cover portion 440 may be in the base plate 410 with respect to the display panel 10 (see example). Figure 1 The filling layer 450 is located between the base plate 410 and the cover portion 440.

[0147] In one or more embodiments, a stop 460 projecting from the base plate 410 toward the cover portion 440 may be further arranged or provided between two regions of the adjacent slot 420 in the width direction (e.g., the X-axis direction) of the slot 420.

[0148] refer to Figure 6 As an example, groove 420 may form or provide at least two or more distinct regions, and these two or more distinct regions may have different depths. For example, as Figure 6 As shown, the groove 420 may include a first region with the deepest depth (e.g., Figure 6 The groove in the left region), and the second region with the shallowest depth (e.g., Figure 6 The groove 420 has a groove in the right-hand region and a third region having a depth at a level between the two depths, as described in one or more embodiments. This is one example, and the groove 420 may have two or more regions with different depths, and as another example, the groove 420 may have four or more regions with different depths.

[0149] In one or more embodiments, the slot 420 may form or provide at least two distinct regions, and the at least two distinct regions may have different widths. In one or more embodiments, the slot 420 may have multiple distinct regions, and these distinct regions may have widths different from each other. As another example, the slot 420 may have four or more regions with different widths.

[0150] When the shape and height of certain portions of the groove 420 are adjusted to form a closed loop, the flexible tube 430 disposed in the groove 420 can be transformed into one or more suitable shapes, even within a heat dissipation member 40.

[0151] If (for example, when) the heat dissipation component 40 is used to include a groove 420 having areas with different depths and / or widths, the area of ​​the flow path through which the coolant flows can be precisely or appropriately controlled, and the dissipation effect of the heat generated in the display panel 10 can be improved or enhanced.

[0152] Figure 7 For illustrative purposes only Figure 1 A cross-sectional view of another example of a heat dissipation component.

[0153] The heat dissipation component 50 may include a base plate 510 having a groove 520, a flexible tube 530 inserted into the groove 520, a cover portion 540 covering the base plate 510 and the flexible tube 530, and a filler layer 550 between the base plate 510 and the cover portion 540.

[0154] For example, a flexible tube 530 formed or provided to allow at least fluid (e.g., fluid and / or solid) to move may be in a groove 520 in one surface of the base plate 510, and a cover portion 540 may be provided between the base plate 510 and the display panel 10 (see example). Figure 1 The filling layer 550 is located between the base plate 510 and the cover portion 540.

[0155] In one or more embodiments, a stop protruding from the base plate 510 toward the cover portion 540 may be further arranged or provided in the adjacent slot 520 in the width direction of the slot 520 (e.g., Figure 7 Between two regions along the X-axis.

[0156] refer to Figure 7 In one example, slot 520 may be formed or provided as having a width direction (e.g., Figure 7 The groove 520 may have regions of varying depths along its X-axis direction. For example, the groove 520 may have regions with the deepest depth corresponding to the two edges relative to the width direction, and the regions between them may be shallower in depth. For example, the groove 520 may have the maximum depth value in the regions corresponding to the two edges relative to the width direction, and the depth value of the central region between them may be the minimum. For example, the groove 520 may have a protruding shape, wherein the region between the two edges relative to the width direction (e.g., the central region) faces the cover portion 540.

[0157] In one or more embodiments, the cover portion 540 may have a protruding shape such that the region (e.g., the central region) between the regions corresponding to the edges on both sides of the width direction of the groove 520, compared to the regions corresponding to the edges on both sides of the groove 520, faces the base plate 510.

[0158] Depending on the depth to the bottom of the groove 520 or the extent to which the cover portion 540 protrudes into the flexible tube 530, the central region of a flexible tube 530 or its adjacent region may be combined to define two separate internal spaces 531.

[0159] The internal space 531 through which the fluid moves in the flexible tube 530 may include a first space 532 and a second space 533 that is spaced apart from and / or separated from the first space 532 (e.g., spaced apart or separated).

[0160] In one or more embodiments, the space inside a flexible tube 530 may be divided into multiple spaces to improve or enhance the precise or appropriate control characteristics of the coolant flow path. For example, in a machined groove in a base plate, it may be difficult to reduce the distance between a groove portion extending along a surface of a rectangular (e.g., substantially rectangular) shaped base plate and a groove portion overlapping that groove portion in a perpendicular (e.g., substantially perpendicular) direction on that surface, while... Figure 7 In one or more embodiments of the heat dissipation member 50, two flow paths may be formed or provided with a flexible tube 530, thereby alleviating the limitation on the distance between slot portions that overlap each other in the vertical (e.g., substantially vertical) direction of one surface.

[0161] As an example, when the shape and height of certain portions of the groove 520 are adjusted to form a closed loop, the flexible tube 530 disposed in the groove 520 can be transformed into one or more suitable shapes, even within a heat dissipation member 50.

[0162] If the heat dissipation member 50 (where the internal space 531 of one of the flexible tubes 530 includes a first space 532 and a second space 533 spaced apart from and / or separated (e.g., spaced apart or separated) from the first space 532) is used by adjusting the depth of the bottom of the slot 520 or the extent to which the cover portion 540 protrudes into the flexible tube 530, the area of ​​the flow path through which the coolant flows can be precisely or appropriately controlled, and the dissipation effect of the heat generated in the display panel 10 can be improved or enhanced.

[0163] Figure 8 For illustrative purposes only Figure 1 A cross-sectional view of another example of a heat dissipation component.

[0164] The heat dissipation component 60 may include a base plate 610 having a groove 620, a flexible tube 630 inserted into the groove 620, a cover portion 640 covering the base plate 610 and the flexible tube 630, and a filler layer 650 between the flexible base plate 610 and the cover portion 640.

[0165] For example, a flexible tube 630 formed or provided to allow at least fluid (e.g., fluid and / or solid) to move may be in a groove 620 in one surface of the base plate 610, and a cover portion 640 may be provided between the base plate 610 and the display panel 10 (see example). Figure 1 The filling layer 650 is located between the base plate 610 and the cover portion 640.

[0166] In one or more embodiments, a stop protruding from the base plate 610 toward the cover portion 640 may be further arranged or provided in the adjacent slot 620 in the width direction of the slot 620 (e.g., Figure 8 Between two regions along the X-axis.

[0167] The groove 620 may have multiple protrusions formed or provided at its bottom, and the cover portion 640 may also have multiple protrusions facing the flexible tube 630. (See reference) Figure 8 In one example, the groove 620 may include two protrusions at the bottom, and the cover portion 640 may include two protrusions facing the flexible tube 630.

[0168] When the cover portion 640 and the base plate 610 are joined together, multiple joining areas can be created or provided in the flexible tube 630 through the protrusions at the bottom of the groove 620 and the protrusions of the cover portion 640, and correspondingly, multiple internal spaces 631 can be defined. (See reference) Figure 8 In an example of a flexible tube 630, two joining regions may be created or provided by two protrusions at the bottom of the groove 620 and two protrusions of the cover portion 640, and the interior space 631 may include a first space 632, a second space 633 and a third space 634 that are spaced apart and / or separated (e.g., spaced apart or separated) from each other.

[0169] In one or more embodiments, the interior space of a flexible tube 630 may be divided into multiple spaces to improve or enhance the precise or appropriate control characteristics of the coolant flow path. For example, in a machined groove in a base plate, it may be difficult to reduce the distance between a groove portion extending along a surface of a rectangular (e.g., substantially rectangular) shaped base plate and a groove portion overlapping that groove portion in a perpendicular (e.g., substantially perpendicular) direction on that surface, while... Figure 8 In one or more embodiments of the heat dissipation member 60, multiple flow paths may be formed or provided with a flexible tube 630, thereby alleviating the limitation on the distance between slot portions that overlap each other in the vertical (e.g., substantially vertical) direction of the surface.

[0170] As an example, when the shape and height of certain portions of the slot 620 are adjusted to form a closed loop, the flexible tube 630 disposed in the slot 620 can be transformed into one or more suitable shapes, even within a heat dissipation member 60.

[0171] If (for example, when) multiple combined areas of the slot 620 and the cover portion 640 are created or provided, and the heat dissipation member 60 (where the internal space 631 of the flexible tube 630 includes a first space 632, a second space 633, and a third space 634 that are spaced apart and / or separated (e.g., spaced apart or separated) from each other) is used by adjusting the depth to the bottom of the slot 620 or the extent to which the cover portion 640 protrudes into the flexible tube 630, the area of ​​the flow path through which the coolant flows can be precisely or appropriately controlled, and the dissipation effect of the heat generated in the display panel 10 can be improved or enhanced.

[0172] Figure 9 For illustrative purposes only Figure 1 Another example of a heat dissipation component is shown in a plan view, and Figure 10 For illustrative purposes only Figure 9 An enlarged example of area B in the image.

[0173] The heat dissipation component 30' may further include a connector 370 into which a flexible tube 330' is inserted. At least one region of the flexible tube 330' may be connected to the connector 370, and, for example, the connector 370 may be connected to the flexible tube 330' to communicate with the internal space 331 of the flexible tube 330'. For example, both ends of the flexible tube 330' may be connected to the connector 370.

[0174] In one or more embodiments, a valve may be added to connector 370 to regulate the coolant injected into flexible tube 330'. The valve may be connected to connector 370, the internal space 331 of flexible tube 330' may be made into a vacuum state, flexible tube 330' may be filled with a set or specific amount of coolant, and then flexible tube 330' may be completed to simplify the coolant injection process.

[0175] In addition to the hole through which the flexible tube 330' is inserted, the connector 370 may further include a separate injection port 371. In one or more embodiments, even if (e.g.) coolant needs to be re-injected or additionally injected due to problems such as defects, the process can be facilitated because the coolant can be injected through the completed flexible tube 330' at the injection port 371.

[0176] In one or more embodiments, as an example, connector 370 may be connected to a flexible tube 330' closest to a surface of the base plate 310 with a rectangular (e.g., substantially rectangular) shape. In one or more embodiments, inlet 371 may facilitate the addition or re-injection of coolant from the outside of the heat dissipation member 30' toward the inside of the heat dissipation member 30'.

[0177] After the coolant is injected, the inlet 371 can be blocked. For example, an openable cap or an insertable member inserted into the inlet 371 can be arranged or provided at the inlet 371 to block the inlet 371.

[0178] Figures 11 to 13 A cross-sectional view is shown as an example of a method for manufacturing a heat dissipation component according to one or more embodiments.

[0179] For example, Figures 11 to 13 Using manufacturing as an example Figure 4 A diagram illustrating the process of the heat dissipation component 30. This is for illustrative purposes, and the manufacturing method according to one or more embodiments can also be applied in substantially the same manner or modified to a similar degree as needed or required to the heat dissipation components 40, 50, and 60 of other embodiments as described in one or more embodiments.

[0180] In the following text, for ease of explanation, Figure 4 The heat dissipation component 30 is described as an example.

[0181] refer to Figure 11 The groove 320, in which the flexible tube 330 can be placed, can be machined in the base plate 310. The machined groove 320 can be used as a flow path through which fluid flows.

[0182] A filler may be applied to the processed groove 320. For example, the filler, which is the material of the filler layer 350, may be in the groove 320. The filler may be a curable material and may include resin-based materials. In one or more embodiments, the filler may have relatively high thermal conductivity to transfer heat generated from the display panel 10.

[0183] refer to Figure 12 The flexible tube 330 can be placed or provided in the groove 320 to contact the filler. If (e.g., when) the flexible tube 330 is inserted into the groove 320 where filler has been applied, the filler can overflow from the groove 320, and in this state, the filler can be pre-cured. Pre-curing prevents the flexible tube 330 from moving due to the filler in the groove 320 (or reduces the degree or occurrence of movement of the flexible tube 330), and can fix the position of the flexible tube 330. For example, if (e.g., when) curing the filler, heat curing can be used.

[0184] refer to Figure 13After the filler has cured, the cap portion 340 can be moved from the base plate 310 onto the cured filler and flexible tube 330 and can cover the flexible tube 330 and the base plate 310. As an example, a thermoforming clamp can pick up the cap portion 340 and substantially transfer it onto the cured filler and flexible tube 330.

[0185] After the cap portion 340 is placed on the filler and flexible tube 330, heat and pressure can be applied to the cap portion 340. In one or more embodiments, secondary curing of the filler can be performed, and the base plate 310, cap portion 340, and flexible tube 330 can be attached to each other. Secondary curing can structurally stabilize the flexible tube 330 within the groove 320 covered by the cap portion 340 by completely securing the flexible tube 330 with the filler layer 350.

[0186] If, for example, the coolant flows directly into the flow path between the tank 320 and the cover portion 340, a defect of coolant leakage from the base plate 310 and the cover portion 340 of the heat dissipation member 30 may easily occur. However, as in one or more embodiments, the coolant flows within the flexible tube 330, and in addition to the flexible tube 330, the arrangement of the filler layer 350 can reduce or prevent the occurrence of coolant leakage defects.

[0187] In one or more embodiments, the base plate 310 and the cover portion 340 can be protected from damage through stable control of the coolant flow path, and the base plate 310 and the cover portion 340 can be joined together to a degree to which the pressure of the flexible tube 330 can be maintained at a set or specific level. As an example, the base plate 310 and the cover portion 340 can be joined together by spot welding one or more of a plurality of stops 360 included in the base plate 310 to the cover portion 340.

[0188] When the cover portion 340 is engaged with the stop 360, the flexible tube 330 can be compressed by pressing against the cover portion 340. In one or more embodiments, the flexible tube 330 may have one or more suitable shapes when pressed against the cover portion 340, depending on the shape and depth of the groove 320. In one or more embodiments, the flexible tube 330 may have one or more suitable shapes, depending on the shape of the cover portion 340.

[0189] After the base plate 310 and the cover portion 340 are joined together, coolant can be filled into the flexible tube 330. For example, when the two ends of the flexible tube 330 are connected to the connector (e.g., reference...)
