[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 structure that facilitates stable grounding of the display module and the motherboard, referring to Figure 1 , including a display module body 10, a client mainboard 20 is arranged on one side of the display module body 10, and the display module body 10 and the client mainboard 20 are assembled and fixed.

[0024] Reference Figure 1 The display module body 10 includes a display screen 30 and a backlight module 40 which are arranged in sequence. The display screen 30 is accommodated in the backlight module 40. The side of the backlight module 40 away from the display screen 30 is assembled and fixed with the client mainboard 20. The side of the backlight module 40 away from the display screen 30 is a backlight iron frame 41. The backlight iron frame 41 is grounded to the client mainboard 20 to improve the electrostatic discharge protection function of the display module body 10.

[0025] Reference Figure 1 The backlight iron frame 41 is set at a certain distance from the customer main board 20, and a spring piece 50 for grounding connection is set between the backlight iron frame 41 and the customer main board 20. The spring piece 50 is fixed between the backlight iron frame 41 and the customer main board 20 to achieve the grounding connection between the backlight iron frame 41 and the customer main board 20.

[0026] Reference Figure 1 and Figure 2 The spring piece 50 is arranged in an S shape. The spring piece 50 is formed by continuously bending a long strip of metal sheet into an S-shaped structure. The spring piece 50 includes an upper contact surface 51 and a lower contact surface 52. The upper contact surface 51 and the lower contact surface 52 are respectively located at the upper and lower ends of the spring piece 50. The upper contact surface 51 and the lower contact surface 52 are both flat so as to contact the backlight iron frame 41 and the customer mainboard 20 respectively.

[0027] Reference Figure 1 A ground leakage copper area 21 is provided on the customer main board 20, and the ground leakage copper area 21 is located on the side of the customer main board 20 facing the backlight iron frame 41. The lower contact surface 52 of the spring 50 is connected to the ground leakage copper area 21, and the upper contact surface 51 of the spring 50 is connected to the backlight iron frame 41, so that the spring 50 plays the role of connecting the backlight iron frame 41 and the customer main board 20.

[0029] Further, refer to Figure 1 and Figure 2 The height of the spring 50 is greater than the distance between the backlight iron frame 41 and the client mainboard 20. The spring 50 is elastic. When the display module body 10 and the client mainboard 20 are grounded, the spring 50 is in a compressed state. When the display module body 10 and the client mainboard 20 are assembled, the backlight iron frame 41 squeezes the spring 50 on the ground leakage copper area 21. The spring 50 is compressed by the elastic force, so that the upper contact surface 51 of the spring 50 is in contact with the backlight iron frame 41, thereby realizing the ground connection between the backlight iron frame 41 and the ground leakage copper area 21 on the client mainboard 20, which is convenient for leading out the static electricity in the display module body 10.

[0030] Further, refer to Figure 1 The spring piece 50 is made of metal material, preferably copper. The spring piece 50 made of metal material is provided to facilitate the static electricity on the display module body 10 to be conducted to the ground leakage copper area 21 for release.

[0031] Reference Figure 1 A plurality of spring sheets 50 can be provided according to actual use requirements, and the lower contact surfaces 52 of the plurality of spring sheets 50 are all welded to the ground leakage copper area 21 , so that the spring sheets 50 connect the display module body 10 and the customer mainboard 20 .
