[0023] 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.

[0024] A component protection paper structure, referring to Figure 1 , including a protective paper body 10 , a FPC 20 and a backlight module 30 are arranged on one side of the protective paper body 10 , and the protective paper body 10 is pasted on the FPC 20 and the backlight module 30 .

[0025] Reference Figure 1 A component area 40 is set on the FPC 20, the protective paper body 10 covers the entire component area 40, the size of the protective paper body 10 is larger than the size of the component area 40, and the area of ​​the protective paper body 10 exceeding the component area 40 is pasted on the FPC 20 and the backlight module 30.

[0026] Reference Figure 1 and Figure 2 , a bend 21 is provided on the FPC 20, and the FPC 20 is bent along the bend 21 to the back of the backlight module 30, and the protective paper body 10 is pasted along the bend 21 of the FPC 20 and extends to the component area 40 of the FPC 20. The bend 21 is arranged to protrude from the lower end of the backlight module 30 so that the FPC 20 protrudes from the backlight module 30. The position of the protective paper body 10 at the bend 21 is prone to wrinkles due to the height difference between the bend 21 of the FPC 20 and the backlight module 30. Therefore, a U-shaped groove 11 is provided in the protective paper body 10 relative to the position where the bend 21 of the FPC 20 protrudes from the backlight module 30, and the U-shaped groove 11 is provided on one side of the protective paper body 10 at the bend 21, and the U-shaped groove 11 is connected to the outside.

[0027] Reference Figure 1 and Figure 2The U-shaped groove 11 is located between the outer side of the bend 21 and the backlight module 30. There are two U-shaped grooves 11, which are respectively located at two opposite outer sides of the bend 21 of the FPC 20. The U-shaped groove 11 is used to separate the connection point between the FPC 20 and the backlight module 30 at the bend 21, so that the protective paper body 10 can be attached to the bend 21 of the FPC 20 and the backlight module 30 respectively, so as to reduce wrinkles caused by the height difference.

[0028] Reference Figure 1 and Figure 3 , two U-shaped grooves 11 divide the end of the protective paper body 10 at the bend 21 into three sections, and the three sections of the protective paper body 10 are respectively the adhesive portion 12 located in the middle and the connecting portions 13 located on both sides of the adhesive portion 12. The adhesive portion 12 is used to be pasted at the bend 21 of the FPC 20. The size of the adhesive portion 12 is smaller than the size of the bend 21, and the connecting portions 13 on both sides of the adhesive portion 12 are respectively pasted to the two sides of the bend 21 of the backlight module 30 relative to the FPC 20, and the two U-shaped grooves 11 are respectively located between the adhesive portion 12 and the two connecting portions 13. By setting two U-shaped grooves 11 to divide the end of the protective paper body 10 at the bend 21 into three sections, the protective paper body 10 can be pasted on the bend 21 and the backlight module 30 respectively, so as to play a connecting role and no wrinkles will be generated because the bend 21 protrudes outside the backlight module 30.

[0029] Reference Figure 2 The size of the U-shaped groove 11 is determined according to the protrusion of the bending portion 21 of the FPC 20 from the backlight module 30 .

[0030] Reference Figure 1 When the FPC 20 is bent to the back side of the backlight module 30 , the entire component region 40 is located on the back side of the backlight module 30 .

[0031] Reference Figure 1 The end of the FPC 20 away from the bend 21 is the plug-in terminal 22, which is used to connect to the client host. The plug-in terminal 22 is located on one side of the component area 40, and a part of the protective paper body 10 is pasted on the plug-in terminal 22 near the component. The protective paper body 10 is provided with a clearance groove 14 on both outer sides relative to the plug-in terminal 22. The clearance groove 14 is used to separate the plug-in terminal 22 from the backlight module 30, and does not affect the normal plugging operation of the plug-in terminal 22, so as to prevent the protective paper body 10 from pasting the position of the plug-in terminal 22 on the backlight module 30. The area of ​​the protective paper body 10 located between the two clearance grooves 14 is pasted on the plug-in terminal 22, and the area of ​​the protective paper relative to the plug-in terminal 22 is pasted on the backlight module 30, so as to fix the protective paper body 10 on the backlight module 30, and the protective paper body 10 can cover the entire range of the component area 40.

[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.
