[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0023] A protective structure for improving the insulation of display module components, referring to Figure 1 , including a display module body 10, the display module body 10 includes a display screen 11 and a backlight 12, and the display screen 11 and the backlight 12 are assembled and fixed. An FPC 20 is bound to the display screen 11, one end of the FPC 20 is bound to the display screen 11, and the other end of the FPC 20 is bent to the back of the backlight 12 and fixed to the back of the backlight 12.
[0024] Reference Figure 1 , components 21 are arranged on the FPC 20. After the FPC 20 is bent to the back of the backlight 12, the components 21 are located on the side of the FPC 20 away from the back of the backlight 12, that is, the components 21 are exposed to the outside and are prone to the risk of damage. Therefore, a protective cover 30 is arranged on the back of the backlight 12 to protect the components 21 on the FPC 20. The protective cover 30 is fixed to the periphery of the FPC 20. The protective cover 30 is fixed to the iron frame 121 on the back of the backlight 12, and the protective cover 30 covers the area after the FPC 20 is bent to the back of the backlight 12. The protective cover 30 protects the components 21 to achieve an insulation effect through isolation.
[0025] Further, refer to Figure 2 The protective cover 30 is made of metal iron.
[0026] Further, refer to Figure 1 and Figure 2 The shape of the protective cover 30 matches the shape of the FPC 20 bent to the back of the backlight 12, and the protective cover 30 is arranged along the shape of the FPC 20. The size of the protective cover 30 is larger than the size of the area after the FPC 20 is bent to the back of the backlight 12, and the protective cover 30 covers the range of the components 21, so that the protective cover 30 is entirely arranged outside the FPC 20 to protect the components 21.
[0027] Reference Figure 2The periphery of the protective cover 30 is separated from the periphery of the corresponding area of the FPC 20 by a certain distance, and the protective cover 30 is concave, and the inner depth of the protective cover 30 is greater than the thickness of the FPC 20 plus the height of the component 21, so that the inner bottom of the protective cover 30 is a certain distance away from the top of the component 21. The protective cover 30 is set outside the FPC 20, and the protective cover 30 does not contact the FPC 20 and the component 21, so that the protective cover 30 does not affect the normal use of the FPC 20 and the component 21.
[0028] Reference Figure 1 and Figure 2 The back of the backlight 12 is an iron frame 121, and a fixing component for fixing is arranged between the protective cover 30 and the iron frame 121. The protective cover 30 is fixed to the back of the backlight 12 through the fixing component, so that the protective cover 30 is fixed to the periphery of the FPC 20.
[0029] Reference Figure 2 and Figure 3 The fixing assembly includes a buckle 1211 disposed on the iron frame 121 and a slot 31 opened on the protective cover 30. The buckle 1211 on the iron frame 121 is inserted into the slot 31 on the protective cover 30 to buckle the protective cover 30 on the iron frame 121. There are multiple buckles 1211, and the multiple buckles 1211 are arranged along the outer circumferential direction of the protective cover 30. The multiple buckles 1211 are evenly distributed along the outer shape of the protective cover 30. There are multiple corresponding slots 31 on the protective cover 30, and the slots 31 and the buckles 1211 are correspondingly arranged. The multiple slots 31 are opened along the circumferential direction of the protective cover 30. When the protective cover 30 is covered on the periphery of the FPC 20, the multiple buckles 1211 extend into the multiple slots 31 to buckle the protective cover 30 on the iron frame 121.
[0030] Further, refer to Figure 2 The end of the FPC 20 away from the display screen 11 is used to connect to the customer's mainboard. The end of the FPC 20 away from the display screen 11 is provided with a connector 22, and the connector 22 is used to plug the FPC 20 into the customer's mainboard. When the FPC 20 is bent to the back of the backlight 12, the connector 22 is also located on the back of the backlight 12. The protective cover 30 is provided with a slot 32 at a position relative to the connector 22. The size of the slot 32 is larger than the size of the connector 22, so as not to affect the connection between the connector 22 and the customer's mainboard.
[0031] Reference Figure 1 and Figure 2The protective structure is provided with a protective cover 30 on the outer cover of the FPC 20 to protect the components 21 exposed to the outside. A certain distance is left between the protective cover 30 and the FPC 20 and the components 21 to avoid contact with the FPC 20 and the components 21. The protective cover 30 achieves insulation of the components 21 by isolation, and the protective cover 30 has strength and toughness, which can greatly improve the protection of the FPC 20 and the components 21. The protective cover 30 is simply snapped onto the back of the backlight 12, and the operation is simple.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
