[0024] 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.

[0025] A module FPC bending and fixing structure, referring to Figure 1 , including a display module 10, the display module 10 includes a display screen 11 and a backlight 12 arranged in sequence, the display screen 11 and the backlight 12 are fitted and fixed. An FPC 20 is bound to the display screen 11, and a binding end 21 is provided at one end of the FPC 20 facing the display screen 11, and the FPC 20 is bound to the display screen 11 through the binding end 21.

[0026] Reference Figure 2 The end of FPC20 away from the binding end 21 is bent to the back of the display screen 11, and the length of the end of the display screen 11 bound with FPC20 is longer than the length of the corresponding end of the backlight 12. After FPC20 is bent to the back of the display screen 11, FPC20 is located above the backlight 12.

[0027] Reference Figure 1 and Figure 2 The backlight 12 is provided with a clamping assembly for clamping and fixing the FPC 20. The clamping assembly extends from one side of the backlight 12 to clamp the FPC 20 on the back of the display screen 11. The back of the backlight 12 is a glue frame 121, and the clamping assembly is arranged on the glue frame 121. The clamping assembly and the glue frame 121 are integrally formed. The clamping assembly is located on the side of the glue frame 121 away from the binding end 21 of the FPC 20, so that when the clamping assembly fixes the FPC 20, it will not affect the binding of the FPC 20 and the display screen 11.

[0028] Reference Figure 2-4 The clamping assembly includes a pressure strip 30 extending from the upper end of the glue frame 121 and a clamping block 40 arranged at one end of the pressure strip 30. The pressure strip 30 extends upward from the glue frame 121 toward one end of the FPC 20. The pressure strip 30 extends along the height direction of the display screen 11. The length of the pressure strip 30 is adapted to the width of the FPC 20 bent to the back of the display screen 11.

[0029] Reference Figure 2 and Figure 3The pressure strip 30 abuts against one side of the FPC 20, and a contact block 31 for strengthening the contact is provided on the side of the pressure strip 30 facing the FPC 20. The contact block 31 is provided along the length direction of the pressure strip 30, and the side of the contact block 31 away from the pressure strip 30 abuts against the FPC 20, thereby fixing the part of the FPC 20 that is bent to the display screen 11.

[0030] Further, refer to Figure 2 and Figure 3 The abutting block 31 is made of rubber material, so as to abut against the FPC 20 without damaging the FPC 20 .

[0031] Reference Figure 2 and Figure 3 The clamp block 40 is arranged at one end of the pressure strip 30 away from the glue frame 121, and the clamp block 40 is arranged perpendicular to the pressure strip 30, and the clamp block 40 is arranged along the direction of the bend of the FPC 20. The clamp block 40 is arranged in an arc shape, and the arc shape of the inner wall of the clamp block 40 is adapted to the arc shape of the bend of the FPC 20. The FPC 20 is a flexible circuit board, and the FPC 20 can be bent to the back of the display screen 11 along the arc shape of the inner wall of the clamp block 40 during the bending process, so that the bend of the FPC 20 is adapted to the arc shape of the inner wall of the clamp block 40, so that after the FPC 20 is bent, the inner wall of the clamp block 40 is in contact with the bend of the FPC 20.

[0032] Reference Figure 2 and Figure 3 A rubber pad 41 is provided on one side of the clamp block 40 facing the FPC 20 , and the rubber pad 41 is used to abut against the bending position of the FPC 20 , thereby further fixing the position of the FPC 20 .

[0033] Reference Figure 2 and Figure 3 The rubber pad 41 is provided with a double-sided adhesive tape 50 at the position of the bending part of the FPC 20, and a release film is provided on the side of the double-sided adhesive tape 50 facing the FPC 20. When the FPC 20 is bent, the abutment block 31 on one side of the pressure strip 30 abuts against the part of the FPC 20 bent to the back of the display screen 11, and the pressure block presses the FPC 20 so that the FPC 20 fits the arc shape of the inner wall of the pressure block. After determining the fixed position of the FPC 20, the release film on the double-sided adhesive tape 50 is torn off so that the rubber pad 41 and the FPC 20 are adhered and fixed.

[0034] Reference Figure 2 and Figure 3 By integrally forming a clamping component on the glue frame 121 on the back of the backlight 12, the FPC20 can be clamped and fixed after the FPC20 is bent, thereby eliminating the need to attach the double-sided adhesive 50 after the FPC20 is bent, thereby avoiding the risk of the double-sided adhesive 50 being attached skewed.

[0035] 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.
