[0020] In order to facilitate the understanding of the present application, the present application will be described more fully with reference to the related drawings.

[0021] A display module and customer mainboard grounding structure, referring to Figure 1 , comprising a display module 10, one side of the display module 10 is provided with a customer mainboard 20, and the display module 10 and the customer mainboard 20 are assembled and fixed.

[0022] The display module 10 comprises a display screen 11 and a backlight 12, and the backlight 12 is located on the side of the display module 10 facing the customer mainboard 20. After the display module 10 and the customer mainboard 20 are assembled, there is a certain gap between the backlight 12 and the customer mainboard 20, which is not conducive to the grounding connection between the display module 10 and the customer mainboard 20. Therefore, the side of the backlight 12 facing the customer mainboard 20 is provided with a spring sheet 30 for grounding connection with the customer mainboard 20.

[0023] The back of the backlight 12 is an iron frame 121, the spring sheet 30 is formed by extending outward from the upper end of the iron frame 121, the spring sheet 30 is located at the middle position of the iron frame 121, and the position of the iron frame 121 relative to the spring sheet 30 is hollowed out. The spring sheet 30 and the iron frame 121 are integrally formed, one end of the spring sheet 30 is connected with the iron frame 121, and the other end of the spring sheet 30 extends outward and is away from the iron frame 121 by a certain distance.

[0024] Further, one end of the spring sheet 30 facing the customer mainboard 20 is provided with a contact surface 31 for contacting the customer mainboard 20, the contact surface 31 is arc-shaped, and the contact surface 31 contacts the corresponding position of the customer mainboard 20.

[0025] The side of the customer mainboard 20 facing the backlight 12 is provided with a grounding copper leakage area 21, and the end of the spring sheet 30 away from the iron frame 121, i.e. the contact surface 31, is in contact with the grounding copper leakage area 21, so that the spring sheet 30 is located between the backlight 12 and the customer mainboard 20, and the grounding connection between the display module 10 and the customer mainboard 20 is realized.

[0026] Further, the height of the spring sheet 30 protruding out of the iron frame 121 is greater than the distance between the backlight 12 and the customer mainboard 20, and the spring sheet 30 has elasticity. When the display module 10 and the customer mainboard 20 are assembled, the spring sheet 30 on the backlight 12 is pressed to the grounding copper leakage area 21 of the customer mainboard 20, so as to realize the grounding connection between the display module 10 and the customer mainboard 20, thereby improving the electrostatic discharge protection capability of the display module 10.

[0027] Further, the spring sheet 30 is made of conductive metal material, and the spring sheet 30 and the iron frame 121 of the backlight 12 are both made of conductive material. The static electricity generated by the display module 10 is conducted to the iron frame 121 and then to the grounding copper leakage area 21 on the customer mainboard 20 through the spring sheet 30 for release.

[0028] The display module 10 generates heat during operation, and the iron frame 121 of the backlight 12 is provided with a plurality of air vents to timely dissipate the heat generated by the display module 10. The heat dissipation mode through the air vents is relatively single, and the heat will affect the customer mainboard 20 and shorten the service life of the customer mainboard 20. Therefore, the graphite sheet 40 for heat conduction is arranged on the side of the customer mainboard 20 away from the backlight 12, and the graphite sheet 40 is used to quickly conduct the heat on the customer mainboard 20.

[0029] Further, the graphite sheet 40 is provided with the heat sink 50 on the side away from the customer mainboard 20, and the heat sink 50 is used to dissipate the heat conducted by the graphite sheet 40, so as to avoid the heat accumulation on the customer mainboard 20 and affect the performance of the customer mainboard 20.

[0030] The grounding structure of the display module 10 and the customer mainboard 20 is achieved by arranging the elastic sheet 30 between the backlight 12 and the customer mainboard 20 to realize the grounding connection between the display module 10 and the customer mainboard 20. When the display module 10 and the customer mainboard 20 are assembled, the elastic sheet 30 on the backlight 12 is pressed to the grounding copper leakage area 21 of the customer mainboard 20 to realize the grounding connection between the display module 10 and the customer mainboard 20, thereby improving the electrostatic discharge protection capability of the display module 10.

[0031] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
