The organic light emitting layer is disposed between the substrate and the encapsulation layer. The packaging layer is a mixed structure layer of silicon nitride, an organic layer and silicon nitride, so that the structure of the packaging layer is easy to fail under the action of external tensile force or shearing force.
Based on this, in order to avoid the failure of the package layer of the display panel 20 and the failure of the organic light emitting layer of the display panel 20, the service life of the display module is reduced. In the embodiment of the present application, the transparent cover plate 10 is attached to the first surface of the display panel 20, and the heat conductive member 30 is attached to the second surface of the display panel 20. The first surface is a surface of the display panel 20 where the display surface is located, that is, the first surface is a plane of the surface of the touch layer of the display panel 20, and the second surface is a surface opposite to the first surface of the display panel 20, that is, the second surface is a plane of the surface of the back plate of the display panel 20.

It should be noted that, the connection base 101 and the heat conducting component 30 may be fixed by any connection method such as a bolt, a buckle, or welding, which is not limited in the embodiment of the present application. When the connection base 101 and the heat conduction assembly are detachably connected through bolts or buckles, the transparent cover plate 10 and the heat conduction assembly 30 are more conveniently separated when the heat conduction assembly 30 is damaged or repair and maintenance are needed.

As can be seen from the above-described embodiments, in the present embodiment, since the transparent cover plate 10 is attached on the first surface of the display panel 20 and the heat conductive member 30 is attached on the second surface of the display panel 20, the display panel 20 is positioned between the transparent cover plate 10 and the heat conductive member 30. And because the surface that transparent apron 10 and display panel 20 contacted is provided with connection base 101, connection base 101 and heat conduction subassembly 30 are connected, consequently, make display panel 20 by fixed compress tightly between the heat conduction subassembly 30 of display panel 20, on the one hand can dispel the heat through heat conduction subassembly 30 with the heat that display panel 20 produced, on the other hand make the power conduction route of display panel 20 change, can avoid under special operating mode display module assembly receive stretching action, and then the problem that the encapsulation layer that the display module assembly caused under special operating mode is inefficacy has been solved, the life of display module assembly has been prolonged, and make the display module assembly can deal with the operating mode service environment of comparatively complicacy, make the application range of display module assembly not limited.
In order to further reduce the stretching effect of the display module under the special working condition and further improve the heat dissipation effect of the heat conduction assembly 30, in the embodiment of the present application, as shown in fig. 3 and fig. 4, the heat conduction assembly 30 includes a flexible heat conduction pad 301 and a heat dissipation module 302; the heat dissipation module 302 includes a top surface, a bottom surface opposite the top surface, and a side surface intersecting the bottom surface; the flexible heat conductive pad 301 is attached between the second surface of the display panel 20 and the top surface of the heat dissipation module 302, and the top surface of the heat dissipation module 302 is connected to the connection base 101, so that the display panel 20 is pressed between the flexible heat conductive pad 301 and the transparent cover plate 10.
It should be noted that the flexible heat-conducting pad may be a material that can be deformed to a certain extent, such as a flexible graphite heat-conducting sheet, a flexible silicon sheet, or a heat-conducting foam, and can conduct heat. The heat dissipation module 302 is a cuboid-shaped heat conduction member, the heat dissipation module 302 includes a top surface, a bottom surface opposite to the top surface, and a side surface intersecting with the bottom surface, and the top surface of the heat dissipation module 302 is in contact with the flexible heat conduction pad 301. The heat dissipation module 302 may be a metal heat conductive material, such as silver, copper, iron, aluminum, or a non-metal heat conductive material, such as rubber, graphite, which is not limited in this embodiment. Because the heat conduction gasket is attached between the second surface of the display panel 20 and the top surface of the heat dissipation module 302, the top surface of the heat dissipation module 302 is connected with the connection base 101, so that the flexible heat conduction gasket 301 is located between the display panel 20 and the heat dissipation module 302, and the flexible heat conduction gasket 301 is extruded when the heat dissipation module 302 is connected with the transparent cover plate 10, the flexible heat conduction gasket 301 deforms towards the display panel 20 or towards the heat dissipation module, and then the transparent cover plate 10, the display panel 20 and the flexible heat conduction gasket form an integral structure, so that the force is closed, and the display panel 20 cannot be influenced by gravity of other structures to generate shearing action, so that the packaging layer fails. Meanwhile, under the buffer action of the flexible heat conducting gasket, the display panel 20 can be effectively prevented from being stretched.
In addition, under the action of the flexible heat-conducting gasket, no gap exists between the display panel 20 and the heat-radiating module 302, so that the thermal resistance of the display panel 20 is reduced, and heat generated by the display panel 20 can be radiated through the flexible heat-conducting gasket and the heat-radiating module 302.
In addition, in some embodiments, the display module further includes a flip-chip film 40 and a circuit board 50, the display panel 20 is electrically connected to the circuit board 50 through the flip-chip film 40, and the circuit board 50 is fixed on a side surface of the heat dissipation module 302.
The flip chip film 40 is a die pad for fixing the integrated circuit on the substrate of the display panel 20 to the circuit board 50. In this way, after the display panel 20 is electrically connected to the circuit board 50 through the flip chip film 40, the circuit board 50 is disposed on the side surface of the heat dissipation module, on one hand, the heat generated by the circuit board 50 can be conducted out through the heat dissipation module, so that the heat generated by the circuit board 50 is prevented from generating a heat source effect on the display panel 20, and further the service life of the display panel 20 is prolonged. On the other hand, the circuit board 50 can be supported by the heat dissipation module 302, so that the weight of the circuit board 50 is borne by the heat dissipation module 302, and further, the effect of the circuit board 50 on the display panel 20 can be avoided, and the structural integrity of the display panel 20 is further effectively ensured.
Optionally, a fixing stand is provided on a side surface of the heat dissipation module 302, and the circuit board 50 is fixed on the fixing stand. Thus, the circuit board 50 is fixed by the fixing table, and meanwhile, a certain limit can be formed on the circuit board 50 by the fixing table, so that the circuit board 50 is prevented from being shifted. It should be noted that, the circuit board 50 may be disposed on the fixing table through the heat-conducting adhesive, the heat-conducting adhesive may be silica gel formed by mixing polymer materials such as an organic silica gel as a main body, and a filler and a heat-conducting material, so that the heat-conducting adhesive has better heat conduction and electrical insulation properties, and thus, the heat-conducting path of the circuit board 50 may be perfected while the circuit board 50 is fixed, and heat dissipation of the circuit board 50 through the heat dissipation module 302 is more facilitated.
Specifically, a connection base 101 is disposed at a corner of the surface where the transparent cover plate 10 and the display panel 20 contact; the ends of both sides of the heat dissipation module 302 are provided with connection bosses 3021, the connection bosses 3021 are detachably connected to the connection base 101, and the circuit board 50 is fixed between the two connection bosses 3021 of the sides of the heat dissipation module 302.
It should be noted that, taking the transparent cover plate 10 as a square cover plate and the heat dissipation module 302 as a square block structure as an example, four corners of the surface where the transparent cover plate 10 and the display panel 20 contact each other are provided with a connection base 101, and two end portions of two side surfaces of the heat dissipation module 302 are provided with a connection boss 3021. The connection base 101 protrudes from the contact surface of the transparent cover plate 10 and the display panel 20, and the connection boss 3021 protrudes from the side surface of the heat dissipation module 302. In this way, when the cover glass is connected with the heat dissipation module 302, the connection between the display panel 20 and the heat dissipation module 302 cannot be affected due to the arrangement of the connection base 101, meanwhile, the circuit board 50 can be fixed between two connection bosses 3021 on the side surface of the heat dissipation module 302, and then the two connection bosses 3021 arranged on the same side surface form a limiting effect on the circuit board 50, so that the circuit board 50 is prevented from being shifted, meanwhile, a certain protection can be formed on the circuit board 50 through the connection bosses 3021, and the heat dissipation path of the circuit board 50 can be increased through the two connection bosses 3021, so that the heat dissipation of the circuit board 50 is accelerated, and the service life of the circuit board 50 is prolonged.
Furthermore, in some embodiments, the connection base 101 and the connection boss 3021 are detachably connected by threads or snaps. Specifically, in the case of detachable connection between the connection base 101 and the connection boss 3021 through threads, a threaded connection hole may be formed in the connection boss 3021, a screw is disposed at an end portion of the connection base 101, and detachable connection between the connection base 101 and the connection boss 3021 is achieved through connection between the screw and the threaded connection hole. Under the condition that the connection base 101 and the connection boss 3021 are detachably connected through a buckle, a clamping hole can be formed in the connection boss 3021, a clamping head is arranged at the end part on the connection base 101, and the connection base 101 and the connection boss 3021 are detachably connected through the clamping of the clamping head and the clamping groove. In this way, whether the connection base 101 and the connection boss 3021 are detachably connected through threads, or the connection base 101 and the connection boss 3021 are detachably connected through a buckle, the heat dissipation module 302 and the transparent cover plate 10 can be detachably connected, and when the heat dissipation module 302 is damaged or needs to be repaired and maintained, the transparent cover plate 10 and the heat dissipation module 302 are more conveniently separated.
In addition, to further enhance the heat dissipation capability of the heat conduction assembly 30, in the embodiment of the present application, the heat dissipation module 302 includes a plurality of heat conduction through grooves 3022; the heat conducting through groove 3022 penetrates from the top surface of the heat dissipating module 302 to the bottom surface of the heat dissipating module 302.
It should be noted that, since the heat conducting through groove 3022 penetrates from the top surface of the heat dissipating module 302 to the bottom surface of the heat dissipating module 302, the heat transferred from the display panel 20 to the flexible heat conducting pad can be transferred through the heat conducting through groove 3022, which is more beneficial to the rapid transfer of the heat of the display panel 20, and further enhances the heat dissipating effect of the heat dissipating module 302.
Optionally, the spacing between two adjacent heat conducting through grooves 3022 is equal. In this way, the heat dissipation capacity of each part of the heat dissipation module 302 is the same, which is more beneficial to ensuring uniform heat dissipation of the display panel 20 and avoiding damage to the display panel 20 caused by uneven local heat dissipation of the display panel 20.
In some embodiments, at least one of a fan radiator, a water cooled radiator, a heat pipe radiator, or a phase change radiator is also provided in the heat dissipating module 302. For example, in the case that a fan radiator is disposed in the heat dissipation module 302, a mounting hole may be formed in the heat dissipation module 302, and a fan is installed in the mounting hole, and the fan may be driven to rotate by disposing a driving component in the heat dissipation module 302, so that heat is transferred, and thus a heat dissipation effect is achieved. In the case that the heat dissipation module is a water-cooled heat sink, an installation groove can be formed in the heat dissipation module 302, so that the heat dissipation tube is installed in the installation groove, and heat dissipation is performed by using the circulation of cooling liquid in the heat dissipation tube, so that the heat absorption effect is achieved. In the case that the heat-pipe radiator is disposed in the heat-dissipating module 302, an installation groove may be formed in the heat-dissipating module 302, so that the heat-dissipating module 302 is installed in the installation groove, and when the heat-pipe radiator is running, heat can be continuously absorbed in the process of continuous evaporation and condensation, so as to achieve the heat-dissipating effect.
It should be noted that, one of a fan radiator, a water-cooled radiator, a heat pipe radiator or a phase-change radiator may be disposed in the heat dissipation module 302, for example, a fan radiator may be disposed in the heat dissipation module 302, and a plurality of fan radiators, water-cooled radiators, heat pipe radiators or phase-change radiators may also be disposed in the heat dissipation module 302, for example, a fan radiator and a heat pipe radiator are disposed in the heat dissipation module 302 at the same time, and the type and number of the heat radiators disposed in the heat dissipation module 302 are determined according to the application scenario of the display module and the heat dissipation requirement of the display module.
As can be seen from the above-described embodiments, in the present embodiment, since the transparent cover plate 10 is attached on the first surface of the display panel 20 and the heat conductive member 30 is attached on the second surface of the display panel 20, the display panel 20 is positioned between the transparent cover plate 10 and the heat conductive member 30. And because the surface that transparent apron 10 and display panel 20 contacted is provided with connection base 101, connection base 101 and heat conduction subassembly 30 are connected, consequently make display panel 20 by fixed compress tightly between the heat conduction subassembly 30 of display panel 20, on the one hand can dispel the heat through heat conduction subassembly 30 with the heat that display panel 20 produced, on the other hand makes the power conduction route of display panel 20 change, can avoid under special operating mode that the display module receives the stretching effect, and then solved the problem that the encapsulation layer inefficacy that the display module caused under special operating mode, prolonged the life of display module.
In addition, the heat conducting assembly 30 includes a flexible heat conducting spacer 301 and a heat dissipating module 302, the heat conducting spacer is attached between the second surface of the display panel 20 and the top surface of the heat dissipating module 302, and the top surface of the heat dissipating module 302 is connected with the connection base 101, so that the flexible heat conducting spacer is located between the display panel 20 and the heat dissipating module 302 due to the fact that the heat conducting spacer is attached between the second surface of the display panel 20 and the top surface of the heat dissipating module 302, and when the heat dissipating module 302 and the transparent cover plate 10 are connected, the flexible heat conducting spacer 301 is extruded to deform towards the display panel 20 or towards the heat dissipating module 302, and then the transparent cover plate 10, the display panel 20 and the flexible heat conducting spacer form an integral structure, so that the force is closed and circulated, and the display panel 20 is not affected by gravity of other structures to generate shearing action, so that the packaging layer is invalid. Meanwhile, under the buffering action of the flexible heat conductive pad 301, the display panel 20 can be effectively prevented from being subjected to the stretching action.
In a second aspect, an embodiment of the present application further provides a display device, where the display device includes the display module of any one of the embodiments. It should be noted that the display device may be a vehicle-mounted display of a vehicle, a display practical in a numerical control machine tool, or a display on another machine or device, which is not limited in the embodiment of the present application.
