[0020] The embodiments of the present application will be described in more detail below with reference to the accompanying drawings. 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, in some large display screens, due to the required brightness, the backlight module needs to be equipped with more LED lights, so the heat is easily transferred to the iron frame covering the light guide plate, making the temperature of the iron frame higher, which in turn causes people to easily get burned when they touch it.

[0024] In view of the above problems, the embodiments of the present application provide a backlight structure with a heat insulation function, which can prevent the heat of the LED from being introduced into the iron frame to prevent burns.

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

[0026] See also Figure 1 A backlight structure with heat insulation function includes a backlight assembly 100 and a heat insulation board 200. The backlight assembly 100 includes a heating element 110 and a first iron frame 120. The heating element 110 is arranged on the first iron frame 120; the heat insulation board 200 is located on one side of the heating element 110, and the heat insulation board 200 is arranged on the first iron frame 120.
