[0051] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0052] Unless otherwise defined, technical or scientific terms used in the present disclosure should have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. The terms "first", "second", and similar terms used in the present disclosure do not denote any order, quantity, or importance, but are used to distinguish different components. Similarly, the terms "one", "a", or "the" and similar terms do not denote a quantity of the specified elements, but indicate the existence of at least one of the elements. The terms "comprise", "comprising", and similar terms are intended to encompass the elements listed after the terms as well as equivalents thereof, and do not exclude other elements.

The terms "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships when the absolute positions of the described objects are changed, and the relative positional relationships can also be changed accordingly.

[0053] The features "parallel", "vertical", and "same" and the like used in the embodiments of the present disclosure include the strict sense of "parallel", "vertical", "same" and the like, and "approximately parallel", "approximately vertical", "approximately same" and the like with a certain tolerance, which, considering the measurement and the tolerance related to the measurement of a specific value (for example, the limitation of a measurement system), represents the acceptable deviation range for a specific value determined by those of ordinary skill in the art. For example, "approximately" can mean within one or more standard deviations, or within 3% or 5% of the value.

[0054] Further, in this document, the terms“substantial,”“essentially,”“approximately,” and“about” are used to describe and account for small variations. When used with an event or circumstance, these terms can encompass the occurrence of the event or circumstance at a close time or iteration as well as instances where the event or circumstance occurs slightly differently, for example, due to natural and expected variations present in the fabrication and measurement of devices.

[0055] It should be understood that, in the example embodiments of the present disclosure, when a layer or element is referred to as being on another layer or substrate, it can be that the layer or element is directly on the other layer or substrate, or there can be an intermediate layer between the layer or element and the other layer or substrate. “A and B are arranged in the same layer” refers to a layer structure formed by using the same mask plate through a one-time patterning process after A and B are formed into a film layer for forming a specific pattern using the same film forming process.

[0056] Before the display screen support structure, display module and display device provided by the embodiments of the present disclosure are described in detail, the related art is described as follows:

[0057] In the related art, the foldable display device is a flexible screen widely used. In some foldable display devices, a main screen and a secondary screen are included, and the light emitting directions of the main screen and the secondary screen are opposite. The secondary screen needs to use a display module separately, which can increase the thickness of the foldable display device, increase the cost, and reduce the heat dissipation performance.

[0058] In order to solve the above problems, the display screen support structure, display module and display device provided by the embodiments of the present disclosure can reduce the thickness of the foldable display device, reduce the cost, and improve the heat dissipation performance.

[0059] As shown in FIG. 1, the display screen support structure 10 of the embodiments of the present disclosure can be used to support a display screen 20, which includes a first display area 210, a second display area 220, and a folding display area 230 between the first display area 210 and the second display area 220.

[0060] For example, the first display area 210 and the second display area 220 can be the non-bending display area 230, which can be flat. However, the first display area 210 and the second display area 220 can also be flexible display areas that can be rolled up in other embodiments.

[0061] The bending display area 230 can have a bending property and can be bent to achieve folding and unfolding of the display screen 20. For example, the display screen 20 can be an active matrix organic light emitting diode (AMOLED) display screen 20 with a flexible resin material such as polyethylene terephthalate (PET) as a substrate.

[0062] As shown in FIGS. 1 and 2, the display screen support structure 10 includes a first support portion 110, a second support portion 120, and a bending connection portion 130. The bending connection portion 130 is connected between the first support portion 110 and the second support portion 120, and at least a partial region of the bending connection portion 130 is bendable. The first support portion 110 is configured to support the first display area 210, the second support portion 120 is configured to support the second display area 220, and the bending connection portion 130 is configured to support the bending display area 230. The first support portion 110 is a rigid or flexible transparent support portion, and the second support portion 120 is made of a heat dissipation material.

[0063] In the above scheme, the first display area 210 of the display screen 20 can be supported by the first support portion 110, and the second display area 220 of the display screen 20 can be supported by the second support portion 120. The bending connection portion 130 can be provided corresponding to the bending display area 230 on the display screen 20 to achieve the bending purpose of the display module composed of the display screen 20 and the display screen support structure 10. For example, in some embodiments, the first display area 210 and the second display area 220 can be folded or unfolded relative to each other when the bending display area 230 and the bending connection portion 130 are bent. In addition, by selecting a rigid or flexible transparent support portion for the first support portion 110, the first support portion 110 can not only be used as a support for the first display area 210, but also can serve as a protective cover for the first display area 210 when the first display area 210 is configured to have a light emitting direction at least toward the first support portion 110. This can effectively reduce the thickness of the display module and reduce costs. In addition, the second support portion 120 is made of a heat dissipation material, which can effectively dissipate heat and improve the heat dissipation performance of the display module.

[0064] In some embodiments, as shown in FIG. 1, the display screen 20 has a first side 20A and a second side 20B arranged oppositely, and the display screen support structure 10 can be arranged on the first side 20A of the display screen 20. For example, the display screen support structure 10 can be attached to the first side 20A of the display screen 20 by bonding, i.e., the first support part 110, the second support part 120, and the bending connecting part 130 can be bonded to the display screen 20, respectively, and different regions of the display screen support structure 10 can be tightly and firmly bonded to the display screen 20 by using the same or different adhesives.

[0065] In the embodiments of the present application, the overall length and width of the display screen support structure 10 are consistent with or substantially consistent with the length and width of the display screen 20. However, it is not limited thereto.

[0066] In addition, the first display area 210 can be a double-sided display, and the light emission direction thereof can include a first light emission direction F1 from the first side 20A and a second light emission direction F2 from the second side 20B. The first support part 110 can be a transparent support plate made of a transparent material. When the first support part 110 supports the first display area 210, the protective cover plate of the first display area 210 can be omitted, and the protective cover plate of the first display area 210 on the first side 20A does not need to be additionally arranged, and the first support part 110 can be directly reused as the protective cover plate of the first display area 210 on the first side 20A, which reduces the thickness of the entire display module and saves material costs.

[0067] In some embodiments, the first display area 210 is configured to have a light emission direction including the first light emission direction F1 and the second light emission direction F2, which means that the display screen 20 uses a display substrate, i.e., a double-sided display substrate, which can emit light from the first light emission direction F1 and the second light emission direction F2 at the first display area 210, and can emit light only from the second side 20B at the second display area 220, or can emit light from the first light emission direction F1 and the second light emission direction F2 at the second display area 220. In this way, the display screen support structure 10 provided in the embodiments of the present application can be applied to a double-sided display module, i.e., the display screen 20 can be a double-sided display screen 20, and the main screen and the auxiliary screen do not need to be arranged separately, which can reduce costs and reduce the thickness of the display module.

[0068] However, the structure of the display screen 20 is not limited to this. For example, in other embodiments, the display screen 20 is configured to have light emission directions including a first light emission direction F1 and a second light emission direction F2, and specifically, the display screen 20 can also include a main screen and a sub-screen, the light emission direction of the main screen is from the second light emission direction F2, the sub-screen is stacked on the main screen, and the light emission direction of the sub-screen is the first light emission direction F1, and the area where the sub-screen coincides with the main screen forms the first display area 210. Compared with the display module in the related art which adopts two modules of the main screen and the sub-screen, although the main screen and the sub-screen are also provided in the embodiment of the present disclosure, the sub-screen can not need to be separately provided with a protective cover plate, and the thickness of the entire display module can still be reduced, and the cost can be reduced. In actual application, the specific structure of the display screen 20 can be reasonably selected according to actual application requirements.

[0069] In addition, the second display area 220 can be single-sided display or double-sided display. The second support portion 120 mainly plays a supporting role in the second display area 220. Please refer to FIG. 1, the circuit board 27 on the display screen 20 can be bent and attached to the second support portion 120. Therefore, the second display area 220 can emit light or not emit light on the second side 20B, and the second support portion 120 can be made of light-proof material. For the entire display module, the corresponding area of the second display area 220 on the second side 20B can not be displayed. When the second display area 220 emits light on one side, the corresponding area of the second display area 220 on the display screen 20 can be configured to emit light only to the first side 20A, and only the corresponding area of the first display area 210 needs to be configured to emit light on both sides, which can save cost. When the second display area 220 emits light on both sides, the first display area 210 and the second display area 220 can not need to be prepared differently, and the process can be simplified. In actual application, the second display area 220 can be reasonably set to emit light on one side or on both sides according to actual requirements.

[0070] In addition, as an exemplary embodiment, the material of the first support portion 110 can be at least one of transparent glass or transparent polyimide (CPI) material. The first display area 210 can be a rigid or flexible screen. When the first display area 210 is a rigid screen, the first support portion 110 can be made of transparent glass material, which has the characteristics of high strength, high transmittance, light weight and low cost. When the first display area 210 is a flexible screen, the first support portion 110 can be made of one or both of transparent thin glass or transparent polyimide (CPI).

[0071] It should be understood that the above is only an example, and in actual applications, the material of the first support part 110 is not limited thereto, as long as it has a certain modulus sufficient to meet the application requirements of the display device, serves as sufficient rigid support for the first display area 210, and has high light transmittance. The material can be applied to the first support part 110.

[0072] In addition, as an exemplary embodiment, the heat dissipation material can include at least one of a metal material, a metal matrix composite material, a heat-conductive plastic, graphite, or graphene. For example, the heat dissipation material can be selected from a metal material such as steel, aluminum, copper, etc. The metal material has excellent heat dissipation performance, can effectively dissipate heat from the display screen 20 while providing sufficient rigid support for the second display area 220, and as a conductive material, has excellent electrical conductivity, which can meet the electrical conductivity requirements in the display module, such as grounding and other electrical conductivity requirements, which is beneficial to static electricity release.

[0073] In related technologies, the connection structure between the bending connection part 130 and the support part of the display screen support structure 10 applied to the foldable display module is also relatively complex.

[0074] As an exemplary embodiment, as shown in FIGS. 1 and 2, the bending connection part 130 includes a first connection area 131, a second connection area 132, and a bending area 133 between the first connection area 131 and the second connection area 132; the first connection area 131 is adhesively connected to the first support part 110; and the second connection area 132 is spliced with the second support part 120 through the mortise and tenon structure 140.

[0075] The mortise and tenon structure splicing refers to that two spliced objects are respectively formed into convex and concave shapes at the connection part.

[0076] With the above scheme, the bending connection part 130 is adhesively connected to the first support part 110, which is connected through adhesion, and the connection structure is simple. The structure of the first support part 110 is relatively simple, and no separate splicing structure needs to be provided on the first support part 110. Taking the glass material as an example, the preparation process requirement of the glass substrate is relatively low. In addition, the mortise and tenon structure 140 is used to splice the bending connection part 130 and the second support part 120, which can meet the firmness of the connection structure. Taking the metal material as an example, the preparation process of the second support part 120 is also easy to realize the mortise and tenon structure 140 connection, and the process difficulty requirement is not high.

[0077] As an exemplary embodiment, please refer to FIG. 1 and FIG. 3, the display screen supporting structure 10 has a first surface 10A and a second surface 10B, the second surface 10B is a surface facing the display screen 20, and the first surface 10A is a surface away from the display screen 20. The first supporting part 110 includes a first edge 111 for connecting with the bending connecting part 130, and the first surface 10A includes a first edge area 112 adjacent to the first edge 111. At least a part of the first connecting area 131 extends from the bending area 133 towards the first supporting part 110 and overlaps the first edge area 112 for pasting and fixing.

[0078] By the above scheme, at least a part of the first connecting area 131 of the bending connecting part 130 extends to the first surface 10A of the first supporting part 110, and the overlapping position of the first edge area 112 of the first surface 10A and the first connecting area 131 can be pasted and fixed by means of glueing or the like. This way, the manufacturing and assembling process is simple, and the overlapping area of the first connecting area 131 and the first edge area 112 can meet the requirements of firmness of bonding.

[0079] Furthermore, the bending connecting part 130 can be configured as an integrally formed structure, and the first connecting area 131 can be integrally connected and extended from the bending area 133, which is simple in structure.

[0080] As an exemplary embodiment, as shown in FIG. 3, the first supporting part 110 includes a peripheral side surface 113 between the first surface 10A and the second surface 10B. At least another part of the first connecting area 131 is connected in close contact with the peripheral side surface 113 corresponding to one side of the first edge 111.

[0081] By the above scheme, the bonding area of the first supporting part 110 and the first connecting area 131 is further increased, and there is no gap between the first edge 111 of the first supporting part 110 and the first connecting area 131, which ensures the compactness and firmness of the entire structure.

[0082] As an exemplary embodiment, as shown in FIG. 2 and FIG. 4, the second supporting part 120 includes a second edge 121 for connecting with the bending connecting part 130. One of the second connecting area 132 and the second edge 121 includes a first matching surface 151, and the other includes a second matching surface 152. The mortise and tenon structure 140 includes at least one recess 141 provided on the first matching surface 151 and at least one protrusion 142 provided on the second matching surface 152, and the protrusion 142 is embedded into the corresponding recess 141.

[0083] For example, when the first fitting surface 151 is located on the second connecting area 132 and the second fitting surface 152 is located on the second supporting part 120, the first fitting surface 151 can be the entire or partial circumferential surface of the second connecting area 132 between the first surface 10A and the second surface 10B, and the second fitting surface 152 can be the entire or partial circumferential surface of the second edge 121 between the first surface 10A and the second surface 10B.

[0084] The first fitting surface 151 and the second fitting surface 152 can be tightly spliced together through the mortise and tenon splicing of the recesses 141 and the protrusions 142.

[0085] The specific structure of the recesses 141 and the protrusions 142 can have various implementation manners, and the following exemplary embodiments of the recesses 141 and the protrusions 142 are described.

[0086] As an exemplary embodiment, as shown in FIGS. 4 and 5, at least one of the recesses 141 includes a first recess 1410 recessed from the first fitting surface 151, and at least one of the protrusions 142 includes a first protrusion 1420 protruding from the second fitting surface 152; the first protrusion 1420 includes an extension part 1421 and a clamping block part 1422, the clamping block part 1422 is located on the side of the extension part 1421 away from the second fitting surface 152, the size of the clamping block part 1422 is greater than the size of the extension part 1421, and the junction position between the clamping block part 1422 and the extension part 1421 forms a first concave-convex stop structure 1423; the groove body of the first recess 1410 includes a large-diameter area 1411 adapted to the clamping block part 1422 and a small-diameter area 1412 adapted to the extension part 1421, and the junction position between the large-diameter area 1411 and the small-diameter area 1412 forms a second concave-convex stop structure 1413; wherein the extension part 1421 is embedded into the small-diameter area 1412, and the clamping block part 1422 is embedded into the large-diameter area 1411, so as to be clamped through the cooperation of the first concave-convex stop structure 1423 and the second concave-convex stop structure 1413.

[0087] With the above scheme, by designing the first protrusion 1420 to have a clamping block portion 1422 and an extension portion 1421, the sizes of the clamping block portion 1422 and the extension portion 1421 are different, so that the joint between the two is in a concave-convex transition, i.e., the first concave-convex stop structure 1423 is formed, at the same time, the first groove 1410 is configured to have a large-diameter region 1411 and a small-diameter region 1412, the large-diameter region 1411 is adapted in shape and size to the clamping block portion 1422, the small-diameter region 1412 is adapted in shape and size to the extension portion 1421, the joint between the large-diameter region 1411 and the small-diameter region 1412 is in a concave-convex transition, i.e., the second concave-convex stop structure 1413 is formed, therefore, the first protrusion 1420 is embedded in the first groove 1410, through the concave-convex matching stop structure, the splicing stability can be further improved.

[0088] Illustratively, the large-diameter region 1411 and the clamping block portion 1422 are regular shapes or special shapes. Among them, the regular shape includes at least one of a rectangular shape, a circular shape, an elliptical shape, a trapezoidal shape, a triangular shape, and a rhombic shape in the cross-sectional shape perpendicular to the first face 10A direction.

[0089] Illustratively, as shown in FIG. 4, the clamping block portion 1422 and the large-diameter region 1411 are both configured as rectangular blocks that fit each other; as shown in FIG. 5, the clamping block portion 1422 and the large-diameter region 1411 are both configured as spheres that fit each other.

[0090] When the clamping block portion 1422 and the large-diameter region 1411 are both configured as spheres, when the bending connection portion 130 is bent, stress concentration problems are less likely to occur at the mortise and tenon splicing position.

[0091] In addition, illustratively, as shown in FIG. 4, the extension portion 1421 extends along a first direction X, which can mean a direction that is substantially parallel to the first face 10A and points from the second support portion 120 to the bending connection portion 130.

[0092] “Substantially parallel” herein includes a certain tolerance, taking into account measurement and tolerance related to a particular measurement (e.g., limitations of a measurement system), which represents an acceptable deviation range for a particular value determined by those of ordinary skill in the art. For example, “substantially” can mean within one or more standard deviation values, or within 3% or 5% of the standard deviation value.

[0093] In some embodiments, the first recess 1410 can be only one, extending along the second direction Y and through the second connecting area 132 or the second support portion 120. Similarly, the first protrusion 1420 can be only one, extending along the second direction Y and through the second support portion 120 or the second connecting area. The second direction Y can be the extending direction of the second edge 121. In this way, when splicing the second connecting area and the second support portion 120, the first protrusion 1420 can be pushed from one end of the second direction Y to the other end of the first recess 1410, so that the first protrusion 1420 is embedded into the first recess 1410, facilitating assembly. Alternatively, the splicing process of the second connecting area 132 and the second support portion 120 can also be, for example, that the first recess 1410 is arranged on the bending connecting portion 130, and the material of the second support portion 120 in a molten state is filled into the first recess 1410 to form a matching first protrusion 1420 in the first recess 1410, thereby achieving the splicing purpose.

[0094] In other embodiments, the number of the first recess 1410 and the first protrusion 1420 can also be multiple, and can be arranged in sequence along the extending direction of the second edge 121, one first recess 1410 corresponding to one first protrusion 1420.

[0095] For example, the second connecting area 132 is provided with at least two first recesses 1410 and at least two first protrusions 1420, and the first recesses 1410 and the first protrusions 1420 are staggered along the extending direction of the second edge 121. Similarly, the second support portion 120 is provided with at least two first protrusions 1420 and at least two first recesses 1410, and the first recesses 1410 and the first protrusions 1420 are staggered along the extending direction of the second edge 121. In this way, one first recess 1410 on the second connecting area can correspond to one first protrusion 1420 on the second support portion 120, and one first recess 1410 on the second support portion 120 can correspond to one first protrusion 1420 on the second connecting area, so as to achieve a mortise and tenon splicing structure similar to a crossed finger, which can further improve the splicing stability.

[0096] For example, an adhesive material can also be filled in the gap between the first recess 1410 and the first protrusion 1420 to further improve the splicing stability. Moreover, the adhesive material can be a thermally and electrically conductive adhesive material to improve the heat dissipation and electrical conductivity.

[0097] In addition, as another exemplary embodiment, as shown in FIGS. 6-9, at least one of the grooves 141 includes a second groove 1430 recessed from the first mating surface 151, and at least one of the protrusions 142 includes a second protrusion 1440 protruding from the second mating surface 152; the second protrusion 1440 includes an extension portion 1441 extending along a protruding direction of the second protrusion 1440 relative to the second mating surface 152, and a hook portion 1442 bent at least once relative to the extension portion 1441; a groove body of the second groove 1430 includes an extension region 1431 and a hook mating region 1432, the extension portion 1441 is located in the extension region 1431, and the hook portion 1442 is embedded in the hook mating region 1432.

[0098] In the above scheme, the extension portion 1441 can extend along a first direction X, which is substantially parallel to the first surface 10A and perpendicular to an extension direction of the second edge 121. The hook portion 1442 can be bent at least once relative to the extension portion 1441, and the fitting between the hook portion 1442 and the hook mating region 1432 of the second groove 1430 can improve the fitting stability.

[0099] Exemplarily, the second groove 1430 is provided on one of the second support portion 120 or the bent connecting portion 130, and an edge region of the first surface 10A of the one adjacent to the first mating surface 151 is penetrated by the second groove 1430, and the extension portion 1441 is embedded in the second groove 1430.

[0100] With the above scheme, the second support portion 120 and the bent connecting portion 130 can be respectively manufactured, and the structure of the second groove 1430 or the second protrusion 1440 for the mortise-tenon fitting can be respectively formed on the second support portion 120 and the bent connecting portion 130. Taking the second support portion 120 provided with the second protrusion 1440 and the second connecting region 132 provided with the second groove 1430 as an example, since the first surface 10A of the second groove 1430 adjacent to the first mating surface 151 is penetrated to the second groove 1430, i.e., the second groove 1430 is directly exposed to the first surface 10A between the second support portion 120 and the bent connecting portion 130, the second protrusion 1440 can be embedded in the second groove 1430.

[0101] Exemplarily, a side surface of the extension 1421 facing away from the second surface 10B is substantially coplanar with the first surface 10A. It should be noted that the term "substantially coplanar" can refer to two surfaces being arranged along the same plane within a range of microns, for example, within 40 μm, 30 μm, 20 μm, 10 μm or 1 μm.

[0102] As an exemplary embodiment, as shown in FIGS. 6-8, the extension 1441 extends along a first direction X, which is substantially parallel to the first surface 10A and substantially perpendicular to the extension direction of the second edge 121. The hook portion 1442 includes a first portion 14421, which extends in a direction pointing from the first surface 10A to the second surface 10B relative to the extension 1421.

The cross-sectional shape of the hook portion 1442 and the extension 1421 is substantially L-shaped.

[0105] With the above scheme, the first portion 14421 can be directly embedded into the first groove 1410 exposed to the first surface 10A, which is simple in assembly process while improving the splicing stability.

[0106] As another exemplary embodiment, as shown in FIGS. 6 and 9, the hook portion 1442 includes:

[0107] a first portion 14421, which extends in a direction pointing from the first surface 10A to the second surface 10B relative to the extension 1421;

[0108] a second portion 14422, which extends in the first direction X relative to the first portion 14421.

[0109] With the above scheme, by providing the second portion 14422, the number of bending of the hook portion 1442 is increased, a more complex hook structure is formed, and the splicing stability can be further improved.

[0110] Exemplarily, the first portion 14421 and the second portion 14422 can be regular shapes or special shapes, wherein the regular shapes include at least one of a rectangular, circular, elliptical, trapezoidal, triangular, and diamond shape in a cross-sectional shape in a direction perpendicular to the first surface 10A. Specifically, referring to the drawings, the cross-sectional shapes of the first portion 14421 and the second portion 14422 are both rectangular.

[0111] In addition, referring to FIG. 6, the second portion 14422 can be bent and extended in one direction relative to the first portion 14421 along the first direction X, for example, the second portion 14422 is extended in a direction close to the extension 1421 along the first direction X, at this time, the cross-sectional shapes of the first portion 14421 and the second portion 14422 are substantially U-shaped. In an embodiment not shown, the second portion 14422 can also be extended in a direction away from the extension 1421 along the first direction X, at this time, the cross-sectional shapes of the first portion 14421 and the second portion 14422 are substantially Z-shaped.

[0112] In addition, referring to FIG. 9, the second portion 14422 includes a first sub-portion 14422a and a second sub-portion 14422b, the first sub-portion 14422a and the second sub-portion 14422b are bent and extended relative to the first portion 14421 along a first parallel direction X1 parallel to the first surface 10A, the second sub-portion 14422b is bent and extended relative to the first portion 14421 along a second parallel direction X2 parallel to the first surface 10A, the first parallel direction X1 and the second parallel direction X2 are crossed or opposite.

[0114] It should be understood that the specific structure of the clamping hook portion is not limited thereto.

[0115] It should be noted that in some embodiments, an adhesive material can also be filled in the gap between the second groove 1430 and the second protrusion 1440 to further improve the splicing stability. Moreover, the adhesive material can be selected to be a thermally conductive and conductive adhesive material to improve the heat dissipation and conductivity performance.

[0116] In addition, the material of the bent connection portion 130 can be any suitable material capable of realizing the bending performance, such as metal, plastic, or glass. Exemplarily, the bent connection portion 130 can be made of glass material.

[0119] By providing the hollow patterns 134 or the recess patterns, the bending performance of the bending connection portion 130 can be achieved.

[0120] In some exemplary embodiments, the hollow patterns 134 or the recess patterns 135 on the bending connection portion 130 can be filled with conductive and heat-conductive materials 136 to further improve the conductivity and heat dissipation performance.
