[0020] In order to facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0021] Please refer to Figure 1 , an antistatic display module 10, comprising: a TNT liquid crystal main screen 100, a polarizing plate 200 and a silver paste 300. The TNT liquid crystal main screen 100 includes a visible area 110 and a non-visible area 120; the polarizing plate 200 is disposed above the TNT liquid crystal main screen 100; the silver paste 300 includes a horizontal part 310 of the silver paste, an inclined part 320 of the silver paste and a silver paste connecting part 330. The horizontal part 310 and the inclined part 320 of the silver paste are respectively connected to the silver paste connecting part 330, and the silver paste connecting part 330 is connected to the wire grounding end on the TNT liquid crystal main screen 100. The horizontal part 310 and the inclined part 320 of the silver paste are respectively connected to the polarizing plate 200.

[0022] It should be noted that by connecting the horizontal silver paste portion 310 and the inclined silver paste portion 320 to the polarizer 200 respectively, the contact area between the silver paste 300 and the polarizer 200 is increased. Then, through the connection of the silver paste connecting portion 330 to the wire grounding end on the TFT liquid crystal main screen 100, the connection between the polarizer 200 and the wire grounding end on the TFT liquid crystal main screen is made smooth, so as to timely conduct away the static electricity on the polarizer 200, so that there is no static electricity residue on the polarizer 200, avoiding electrostatic damage to the display module 10 and improving the performance and service life of the display module 10.

[0023] Please refer to again Figure 1 In an embodiment, the area of the polarizer 200 is larger than the area of the visible area 110. With such a setting, it is convenient to connect the polarizer 200 to the horizontal silver paste portion 310 and the inclined silver paste portion 320 on the silver paste 300, ensuring the smooth connection of the conductive circuit.

[0024] Please refer to again Figure 1 In an embodiment, two silver pastes 300 are provided, and the two silver pastes 300 are respectively arranged on both sides of the non-visible area 120. With such a setting, the conductivity of the silver paste 300 can be improved, ensuring that the static electricity is timely conducted away from the polarizer 200.

[0025] Please refer to again Figure 1 In an embodiment, a binding position 121 is provided on the non-visible area 120, and the binding position 121 is arranged at the midpoint between the two silver pastes 300. With such a setting, the circuit on the binding position 121 can be prevented from affecting the circuit for conducting away static electricity by the silver paste 300.

[0026] Please refer to again Figure 1 In an embodiment, an IC chip 400 is further included. The IC chip 400 is arranged on the binding position 121, and the IC chip 400 improves the performance of the product, concentrates the circuit together and reduces the interference of external electrical signals.

[0027] Please refer to again Figure 1 In an embodiment, an FPC 500 is further included. The FPC 500 is arranged on the binding position 121, and the FPC 500 is arranged on one side of the IC chip 400. The FPC 500 is mainly used to connect the display module 10 to other components.

[0028] In an embodiment, an adhesive layer is provided between the polarizer 200 and the TFT liquid crystal main screen 100. With such a setting, the polarizer 200 and the TFT liquid crystal main screen 100 are fixedly connected, avoiding shaking due to unstable connection between the polarizer 200 and the TFT liquid crystal main screen 100, resulting in the generation of static electricity.

[0029] In one embodiment, the adhesive layer is an OCA optical adhesive. When the OCA optical adhesive bonds the polarizer 200 to the TNT liquid crystal main screen 100, it will not affect the clarity of the display area of the display module 10.

[0030] Please refer to again Figure 1 , in one embodiment, the width of the horizontal silver paste portion 310 is the same as the width of the inclined silver paste portion 320. With this setting, the conductivity of the horizontal silver paste portion 310 and the inclined silver paste portion 320 is kept balanced.

[0031] In one embodiment, a conductive layer shielding film is provided on the polarizer 200. The conductive layer shielding film has good conductivity and can timely conduct the static electricity generated on the surface of the polarizer 200 away through the silver paste 300.

[0032] The above-described embodiments merely represent several embodiments of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
