[0023] Currently, functional modules on displays with PCBs generate significant heat over extended periods of operation. Because the PCB is in close proximity to the display, this heat is transferred to the display, causing localized high temperatures and, over time, affecting the display's performance.
[0024] In response to the above problems, an embodiment of the present application provides a heat dissipation structure for a display screen, which can isolate the functional modules on the PCB board from the display screen.
[0025] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0026] See also Figure 1 A heat dissipation structure of a display screen includes: a backlight iron frame 100, a supporting component 200, an FPC board 300 and a heating module 400, wherein the supporting component 200 is arranged on the backlight iron frame 100; the FPC board 300 is arranged on the supporting component 200; and the heating module 400 is arranged on the FPC board 300.
[0027] It should be noted that this application integrates the heating module 400 on the original PCB board 500 onto the FPC board 300, and then sets a supporting component 200 to prop up the FPC board 300 so as to have a certain distance from the back of the backlight iron frame 100, thereby avoiding local high temperature on the back of the backlight iron frame 100 and maintaining a normal display effect.
[0028] See also Figure 1 In one embodiment, a heat dissipation structure of a display screen further includes a PCB board 500, which is disposed on the backlight iron frame 100 and electrically connected to the FPC board 300.

[0034] It should be noted that the design of the first chamfered portion 221 and the second chamfered portion 231 can make the corners of the thermal insulation frame 210 smooth and rounded, thereby increasing the heat dissipation area.
[0035] In one embodiment, a mounting area is defined on the FPC board 300 , and the heating module 400 is disposed in the mounting area.
[0036] It can be understood that there are multiple installation areas, and the number of installation areas is the same as the number of heating modules 400.
