As shown in fig. 1 and 2, the heat dissipation assembly includes a composite heat dissipation film 10 and a protection film 20 attached to one side surface of the composite heat dissipation film 10, an outer dimension of the protection film 20 is larger than an outer dimension of the composite heat dissipation film 10, the protection film 20 is provided with at least one transverse easy-to-tear crease 21, and the at least one easy-to-tear crease 21 is flush with or spaced from an edge of the composite heat dissipation film 10.

The composite heat dissipation film 10 is used for conducting heat from a heating portion of an attached object and uniformly dispersing and distributing the heat, so as to expand a heat dissipation range and maintain the temperature stability of the attached object. Optionally, the composite heat dissipation film 10 may be made of a composite material made of materials such as heat conductive adhesive, heat dissipation foam, and copper foil, which can improve heat dissipation efficiency and have high adhesion performance.

The protective film 20 is provided with at least one easy-tear fold 21 traversing from one side edge to the other side edge, the at least one easy-tear fold 21 dividing the protective film 20 into different regions. That is, different regions of the protective film 20 can be separated along the easy-tear fold 21, and the separation boundary is clear. Moreover, the protective film 20 is made of the same material and is separated by the easy-tearing crease 21, so that the whole stress can be kept, and the protective film can be split along the easy-tearing crease 21 under the action of external force, and the applicable scene range is wide. Optionally, the protective film 20 is configured as a release film.

Therefore, the protection film 20 is attached to the composite heat dissipation film 10 and extends outward along the edge of the composite heat dissipation film 10 to enlarge the connection area of the heat dissipation assembly.

As shown in fig. 4 to fig. 6, the heat dissipation assembly disclosed in the above embodiments is applied to a display device, so as to improve the good adhesion and the good uniformity of the bonding stress between the heat dissipation assembly and the display main body 30 of the display device. In an embodiment, the display screen device includes a display main body 30 and the heat dissipation assembly as described above, and the composite heat dissipation film 10 is attached to the display main body 30. The protective film 20 protruding from the display main body 30 is torn along the easy-to-tear fold 21 and separated from the composite heat dissipation film 10, and the rest of the protective film 20 is attached to the composite heat dissipation film 10.

The display main body 30 is used for outputting information such as graphics and characters according to the signal, and heat is easily generated in the operation process. The composite heat dissipation film 10 is attached to the display main body 30 to diffuse and reduce the temperature of the display main body 30. The protective film 20 and the display main body 30 are respectively located on two side surfaces of the composite heat dissipation film material 10, and the protective film 20 is used for protecting the composite heat dissipation film material 10 and avoiding accidents such as scratches during transportation.

The composite heat dissipation film 10 is attached to the flexible display assembly 31 to keep the overall temperature of the flexible display assembly 31 balanced.

The heat dissipation assembly is attached to the display main body 30, wherein the composite heat dissipation film 10 is adapted and attached to the flexible display main body 30. The heat sink is attached to the display main body 30 by the attaching device 40, wherein the attaching device 40 includes an SCF stage 41 and a roller 42, the SCF stage 41 is used for adsorbing the heat sink, and the roller 42 is used for pressing the heat sink onto the display main body 30, so that the heat sink is attached to and fixed to the display main body 30. In one embodiment, the heat dissipation assembly is attached along the surface of the display main body 30 from one end to the other end. The protective film 20 protruding from the display main body 30 is located in the attaching moving direction of the heat dissipation assembly and the display main body 30.

During the bonding of the heat sink to the display main body 30, the SCF stage 41 is attracted to the protective film 20 so that the entire heat sink moves with the SCF stage 41. The heat sink is attached from one end of the display main body 30 to the other end, and the roller 42 moves along with the SCF stage 41 to synchronously press the heat sink onto the display main body 30. When the extension portion 23 protruding out of the composite heat dissipation film 10 moves along with the SCF stage 41 until the composite heat dissipation film 10 and the display main body 30 are completely attached to each other, the extension portion 23 is separated from the SCF stage 41 and is spaced apart from the display main body 30. Before the extension portion 23 is separated from the SCF stage 41, the separation between one end of the heat dissipation assembly and the display main body 30 is maintained until the roller 42 completely attaches the composite heat dissipation film 10 to the display main body 30, which results in a good attachment effect between the heat dissipation assembly and the display main body 30. The extension part 23 is torn along the easy-to-tear crease 21 under the action of external force and is detached from the main body part 22, so that the main body part 22 is attached to and flush with the composite heat dissipation film material 10, and the display screen device is convenient to move and protect the surface.

Alternatively, the curved portion is provided around the planar portion, the main body portion 22 and the extension portion 23 are both attracted by the SCF stage 41, and the main body portion 22 causes the composite heat dissipation film material 10 to adhere from the curved portion on one side of the planar portion in the direction from the planar portion to the curved portion on the other side, under the urging of the roller 42. After the extension portion 23 is detached along the easy-to-tear crease 21, the main body portion 22 remains attached to the composite heat dissipation film material 10 and moves and transports along with the display screen device until the next process. Extension 23 tears alone and removes, and the display screen device can not produce with the frock tool of back process and interfere, can not cause secondary damage to the product, and the protection is effectual. The main body part 22 is shipped with the display screen device, and the display screen device does not need to be attached with the back protection film 20 again independently, so that the production cost is reduced. The main body 22 can be detached separately when the main body needs to be detached from the composite heat dissipation film 10, and the operation is convenient.
