Although the embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0021] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0022] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In the related art, some larger display screens often need to run uninterruptedly for 24 hours. However, due to the poor heat dissipation effect of the display screen, the temperature of the rear iron frame on the display screen is relatively high. The high temperature of the rear iron frame may cause accidental touch and burns, and the parts in contact with the rear iron frame may age easily.

[0024] In view of the above problems, an embodiment of the present application provides a display module with a heat dissipation structure, which can improve the heat dissipation effect of the display screen and prevent heat from accumulating on the rear iron frame.

[0025] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0027] It should be noted that by setting the thermal conductive coating 210, the thermal conductive coating 210 is coated on the outer surface of the first iron frame 110, so that the heat accumulated on the first iron frame 110 can be adsorbed, and then the heat dissipation effect of the first iron frame 110 can be improved, thereby preventing burns caused by the over-high temperature of the first iron frame 110 and aging of the parts. Furthermore, the main components of the thermal conductive coating are graphene and carbon nanotubes, which are then prepared with a resin carrier through a special grinding and dispersion process. Specifically, graphene is selected to have a sheet structure with a low number of layers and a small sheet diameter, and then compounded with hexagonal carbon nanotubes. The characteristics of graphene and carbon nanotubes having high thermal radiation and thermal infrared emissivity are utilized to make the coating present a macroscopically smooth and microscopically wavy radiation structure unit. Such a structure can greatly increase the heat dissipation area and conductivity, significantly improve the effect of heat exchange, and quickly dissipate the heat of the heating element to the surroundings to achieve a cooling effect.
