[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] This application proposes an integrated structure of backlight FPC and display FPC, please refer to Figure 1, including: backlight FPC10 and display FPC20. Backlight FPC10 is the FPC on the backlight component in the display module. Display FPC20 is the circuit board on the display screen in the display module. Backlight FPC10 and display FPC20 are integrated to reduce the need to attach pad insulation protection paper between backlight FPC10 and display FPC20, and avoid short circuit of the pads between backlight FPC10 and display FPC20. Backlight FPC10 and display FPC20 are electrically connected, so that the circuit functions of backlight FPC10 and display FPC20 are connected, and instructions can be uniformly executed through the mainboard, thereby improving the functional sensitivity of the display screen. Pads are respectively provided on the backlight FPC10 and display FPC20, and the pads are used to weld electronic components such as capacitors, resistors, and diodes, and circuits with specific functions are formed on the pads of the backlight FPC10 and display FPC20 with specific connection relationships. The backlight FPC10 and the display FPC20 are integrated into one, which not only reduces a pressure welding or hand welding process, but also reduces the process of attaching the pad insulation protection paper, thereby saving the material of the pad insulation protection paper, reducing the unit price of the product, and improving the competitiveness of the product in the market.

[0024] In one embodiment, see Figure 1 The backlight FPC 10 is bound to the bottom of the backlight shell 30 in the display module. The backlight FPC 10 and the display FPC 20 can be bent to the other side of the display module to reduce the size of the display module. The display FPC 20 is set below the backlight FPC 10, and the pads of the two do not interfere with each other, saving the use of pad insulation protection paper.

[0025] Furthermore, a plurality of LED lamps 11 are arranged on the backlight FPC 10. The LED lamps 11 have a long service life, high environmental benefits, and are pollution-free, and can reduce the number of times of maintenance and replacement.

[0026] Preferably, the plurality of LED lamps 11 are arranged in the same straight line, so that the light provided by the LED lamps 11 to the display screen is uniform and the brightness of each part of the display screen is consistent.

[0027] Furthermore, the LED lamps 11 are arranged at equal intervals, so that the light provided by the LED lamps 11 to the display screen is further uniform, and the display brightness uniformity of the display screen is better.

[0028] In another embodiment, see Figure 1 The display FPC 20 is provided with a mainboard pad portion 21 at one end away from the backlight FPC 10. The mainboard pad portion 21 is used to be electrically connected to the mainboard, so that the mainboard can control the display screen through the display FPC 20 to execute corresponding instructions and complete corresponding human-computer interaction.

[0029] Furthermore, the integrated structure of backlight FPC and display FPC also includes a backlight shell 30, and the backlight FPC10 is fixed on the inner side of the backlight shell 30, so that the backlight FPC10 can be supported in the display screen to avoid displacement of the backlight FPC10 and the display FPC20, which may cause failure.

[0030] See also Figure 1 The backlight shell 30 is provided with an alignment line 13 on its inner side surface, and the alignment line 13 is used for the alignment of the backlight shell 30 and the backlight FPC 10, so that the backlight FPC 10 can be accurately fixed at the specified position of the backlight shell 30, avoiding the interference between the backlight FPC 10 and other components when assembling other components, resulting in assembly mismatch. In addition, the outer side of the backlight shell 30 is provided with a buckle, which can be snapped with other shells, and the backlight shell 30 is pressed into the matching shell for fixing, thereby improving the efficiency of disassembly and assembly.

[0031] See also Figure 1 A display module includes the above-mentioned integrated structure of backlight FPC and display FPC, a display screen 40 and a display driver IC, the display driver IC is arranged on the upper surface of the display screen 40, and the backlight FPC is arranged on the lower surface of the display screen 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.
