Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to an avoidance structure for preventing an upper iron frame from point-contacting and conducting with silver paste of a display screen. Background Art

[0002] A display module typically includes a display screen and a backlight. The top surface of the glass is covered with a shielding ITO layer. To improve the display screen's anti-static capabilities, conductive silver paste is used to connect the shielding ITO layer on the top glass to the GND layer on the bottom glass. This allows any static electricity remaining on the display screen during use to be conducted away through the conductive silver paste. An upper iron frame is typically located on one side of the backlight, and the display screen is embedded within the upper iron frame. This allows the upper iron frame to potentially contact the silver paste points on the display screen, creating contact and electrical connection between the display screen and the upper iron frame. If significant static electricity is present outside the upper iron frame, it can easily enter the display screen through the upper iron frame, affecting its normal operation. Utility Model Content

[0024] 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.

[0025] An avoidance structure for preventing the upper iron frame from contacting and conducting with the silver paste dots on the display screen, referring to Figure 1 and Figure 2 , includes a display screen 10 and a backlight 20. An upper iron frame 21 is arranged on the periphery of the backlight 20, and the upper iron frame 21 surrounds the backlight 20. The display screen 10 is embedded in the upper iron frame 21 and is fixedly attached to the backlight 20. One side of the display screen 10 away from the backlight 20 is arranged opposite to the inner wall of the upper iron frame 21.

[0026] Referring to Figure 1 and Figure 2 , conductive silver paste dots 30 are arranged on the display screen 10. The conductive silver paste dots 30 are located on the side of the display screen 10 facing the inner wall of the upper iron frame 21. Since the display screen 10 is located within the upper iron frame 21, the conductive silver paste dots 30 on the display screen 10 are prone to contact with the inner wall of the upper iron frame 21, which may cause the upper iron frame 21 to conduct with the circuit on the display screen 10. When there is a large amount of static electricity in the external environment, the static electricity is likely to be conducted to the display screen 10 through the upper iron frame 21, damaging the circuit on the display screen 10 and affecting the normal use of the display screen 10. Therefore, an avoidance hole 211 is provided at the position of the inner wall of the upper iron frame 21 relative to the conductive silver paste dots 30. The avoidance hole 211 is used to avoid the conductive silver paste dots 30 on the display screen 10, so as to prevent the conductive silver paste dots 30 from contacting and conducting with the upper iron frame 21.

[0027] Furthermore, referring to Figure 1 and Figure 2 , the display screen 10 includes an upper glass 11 and a lower glass 12 arranged in sequence. An ITO layer is provided on the upper surface of the upper glass 11, and a grounding line for grounding is provided on the lower glass 12. The conductive silver paste dots 30 connect the ITO layer on the upper glass 11 and the grounding line on the lower glass 12. The size of the lower glass 12 is larger than that of the upper glass 11, so that the conductive silver paste dots 30 are arranged in a stepped manner to connect and conduct the ITO layer and the grounding line.

[0028] Referring to Figure 1 and Figure 2The avoidance hole 211 is opened on the side of the upper iron frame 21 facing the display screen 10. The avoidance hole 211 is opened inward from the side of the upper iron frame 21 facing the display screen 10 to the upper iron frame 21, so as to avoid the conductive silver paste point 30 relative to the position of the upper iron frame 21.

[0029] Further, refer to Figure 1 and Figure 2 The size of the avoidance hole 211 is larger than the area covered by the conductive silver paste point 30, and the area where the conductive silver paste point 30 is located in the display screen 10 is within the coverage range of the avoidance hole 211, so that the upper iron frame 21 has an avoidance effect relative to the area of the conductive silver paste point 30 and its surrounding area, preventing the conductive silver paste point 30 from contacting the inner wall of the upper iron frame 21.

[0030] Further, refer to Figure 1 and Figure 2 The depth of the avoidance hole 211 is 0.5 mm to 1 mm. The bottom of the avoidance hole 211 is a certain distance away from the conductive silver paste dots 30 on the display screen 10.

[0031] Reference Figure 3 and Figure 4 There are two conductive silver paste dots 30 on the display screen 10, and the two conductive silver paste dots 30 are respectively located near the left and right edges of the display screen 10. Two avoidance holes 211 are correspondingly formed on the inner wall of the upper iron frame 21. The two avoidance holes 211 are respectively arranged opposite to the two conductive silver paste dots 30, so that the upper iron frame 21 avoids the conductive silver paste dots 30 on the display screen 10.

[0032] Further, refer to Figure 1 and Figure 2 An insulating layer 40 for insulation protection is provided in the avoidance hole 211 . The insulating layer 40 is located in the avoidance hole 211 to further enhance the insulation effect of the upper iron frame 21 on the conductive silver paste point 30 .

[0033] Reference Figure 1 and Figure 2 The thickness of the insulating layer 40 is 0.1mm-0.2mm. The insulating layer 40 is located on the inner wall of the avoidance hole 211 and is located on the side facing the display screen 10 , thereby enhancing the insulation effect of the upper iron frame 21 on the conductive silver paste dots 30 .

[0034] In one embodiment, referring to Figure 1 and Figure 2, the insulating layer 40 is made of insulating glue. An insulating glue layer is covered in the avoidance hole 211. When the insulating glue solidifies, the insulating layer 40 is formed. The insulating layer 40 can prevent the conductive silver paste dots 30 on the display screen 10 from colliding with the inner wall of the avoidance hole 211 during the transportation of the display module, and the insulating layer 40 can avoid strong static electricity from the outside entering from the upper iron frame 21 and being conducted to the display screen 10 to protect the circuit of the display screen 10.

[0035] In another embodiment, referring to Figure 1 and Figure 2 , the insulating layer 40 is a PI film. The PI film has good insulation. The PI film covers the inner wall of the avoidance hole 211 and can provide a good insulation effect for the inner wall of the avoidance hole 211.

[0036] This avoidance structure is formed by opening an avoidance hole in the upper iron frame 21 relative to the conductive silver paste dots 30 on the display screen 10 to prevent the upper iron frame 21 from contacting the silver paste dots. When strong static electricity comes in from the upper iron frame 21 from the outside, since the conductive silver paste dots 30 and the upper iron frame 21 are separated by the avoidance hole 211, the static electricity cannot be conducted from here, so as to achieve the effect of protecting the grounding circuit of the display screen 10.

[0037] The above embodiments only represent several implementation manners of the present invention. The description 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 invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
