[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 FPC protective paper structure for a display module, referring to Figure 1 , including a display module body 10, the display module body 10 includes a display screen 20 and a backlight module 30. The display screen 20 is bound with an FPC 40, one end of the FPC 40 is bound to the display screen 20, the other end of the FPC 40 is located outside the display screen 20, and the end of the FPC 40 located outside the display screen 20 is bent toward the back of the backlight module 30, so that the end of the FPC 40 away from the display screen 20 is bent to the back of the backlight module 30.

[0025] Reference Figure 1 and Figure 2 The FPC 40 is composed of a component area 41, a bending area 42 and a connection area 43. The component area 41, the bending area 42 and the connection area 43 are sequentially connected to form the FPC 40. A plurality of components are arranged on the component area 41. The bending area 42 is a bendable part of the FPC 40, and the connection area 43 is used to connect the FPC 40 to the customer's mainboard. When the FPC 40 is bent to the back of the backlight module 30, the component area 41, the bending area 42 and the connection area 43 are sequentially arranged from bottom to top.

[0026] Reference Figure 1 The FPC 40 is covered with a protective paper 50 for protecting the component area 41 . The protective paper 50 is made of PET. The protective paper 50 is arranged in a rectangular shape. The protective paper 50 covers the entire component area 41 and part of the bending area 42 . The protective paper 50 is used to protect multiple components on the component area 41 .

[0027] Reference Figure 1 and Figure 2 The size of the protective paper 50 is larger than the size of the component area 41, and the portion of the protective paper 50 that exceeds the component area 41 is connected to the back side of the backlight module 30. The side of the protective paper 50 that faces the component area 41 is provided with adhesive, so that the protective paper 50 is attached to the component area 41 and the backlight module 30 outside the component area 41, thereby fixing the protective paper 50 to the back side of the backlight module 30.

[0028] Reference Figure 1 and Figure 2 The bending area 42 includes a bendable portion 421 and an extension portion 422, the bendable portion 421 and the extension portion 422 are connected, the lower side of the extension portion 422 is connected to the component area 41, and the upper side of the extension portion 422 is connected to the bendable portion 421. The protective paper 50 covers the component area 41 and the extension portion 422, and the bendable portion 421 is outside the coverage of the protective paper 50. The bendable portion 421 is the normal bending length of the FPC 40. When the customer requires a longer bending length, the extension portion 422 is the bending length that the FPC 40 can increase.

[0029] Reference Figure 1 and Figure 3 The protective paper 50 is composed of a first protection zone 51 and a second protection zone 52, and the first protection zone 51 and the second protection zone 52 are integrally formed. The first protection zone 51 covers the entire component zone 41, and the first protection zone 51 is L-shaped. The second protection zone 52 covers the entire extension 422, and the second protection zone 52 is rectangular. The lower side of the second protection zone 52 is connected to the first protection zone 51, and the connection between the lower side of the second protection zone 52 and the first protection zone 51 is the intersection of the component zone 41 and the extension 422.

[0030] Reference Figure 1 and Figure 3 A half-printed line 60 is provided on the protective paper 50, and the half-printed line 60 is provided in an L-shape, and the half-printed line 60 is provided along the connecting line between the second protection area 52 and the first protection area 51, and the half-printed line 60 is used to separate the first protection area 51 from the second protection area 52. The half-printed line 60 is used to facilitate tearing off the second protection area 52 to extend the bendable length of the FPC 40.

[0031] Further, refer to Figure 1 and Figure 3 A tear handle 521 extends outward from one side of the second protection zone 52, and the tear handle 521 is used to tear off the second protection zone 52. The tear handle 521 is set without glue to facilitate tearing off the second protection zone 52. When the customer requires a longer length of the bending zone 42, the second protection zone 52 is torn along the half-stamping line 60 by the tear handle 521 to expose the extension 422, thereby increasing the bendable length of the bending zone 42 without lifting the surrounding protective paper 50. When the customer does not need to increase the length of the bending zone 42, the second protection zone 52 does not need to be torn. The protective paper 50 set in this way is highly practical and has a high utilization rate.

[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.
