[0024] Reference Figure 1 The display module body 10 includes a display screen 30 and a backlight module 40 which are attached to each other. The backlight module 40 is located on the side of the display module body 10 facing the client motherboard 20. The back of the backlight module 40 is a backlight iron frame 41, which is in contact with the client motherboard 20 to achieve grounding connection, so as to release static electricity in the display module body 10.
[0025] Reference Figure 1 The backlight iron frame 41 and the customer main board 20 are arranged at a certain distance, and a conductive sponge 50 for grounding connection is arranged between the backlight iron frame 41 and the customer main board 20. The height of the conductive sponge 50 is greater than the distance between the backlight iron frame 41 and the customer main board 20. The conductive sponge 50 is located between the backlight iron frame 41 and the customer main board 20 to realize the grounding connection between the backlight iron frame 41 and the customer main board 20.
[0026] Reference Figure 1 and Figure 2 The conductive sponge 50 is arranged in a rectangular shape. The conductive sponge 50 is composed of a sponge 51 and a conductive cloth 52 arranged on the periphery of the sponge 51. The conductive cloth 52 is coated on the outer side of the sponge 51 to make the conductive sponge 50 conductive.
[0027] Further, refer to Figure 1 and Figure 2 The conductive sponge 50 is provided with adhesive on one side, and the adhesive side of the conductive sponge 50 is adhered to the customer's mainboard 20 to fix the position of the conductive sponge 50 .
[0028] Further, refer to Figure 1 and Figure 2 The conductive sponge 50 has a conductive adhesive 60 on one side thereof for pasting, and the conductive sponge 50 is pasted on the customer's mainboard 20 by the conductive adhesive 60.
[0029] Reference Figure 1 and Figure 2, a ground leakage copper area 21 is provided on the client main board 20, and the sticky side of the conductive sponge 50 is pasted in the ground leakage copper area 21, so that the conductive sponge 50 is connected to the ground leakage copper area 21.
