Technical Field

[0001] The utility model relates to the technical field of ESD protection structures for COG liquid crystal screens, and more specifically to an ESD protection structure for COG liquid crystal screens. Background Art

[0002] COG LCD displays for industrial, automotive, and medical use. Customers in industrial, automotive, medical and other industries have mandatory requirements for ESD protection. COG LCD displays have the characteristics of low power consumption and low cost. The conventional ESD protection structure is to make a metal shielding layer. The shielding layer is as complete as possible, and the openings and gaps are minimized, such as a closed iron shell, which can shield static electricity to the maximum extent.

[0003] Compared with the description in the "CN201921702746.1" document, the setting of multiple side panels can facilitate the disassembly and replacement of electronic components, and the fiber mesh set on the side panels can also achieve the heat dissipation effect. However, there are still some problems with the overall structural setting. Since the multiple side panels and the base plate are connected by longitudinal plug-in, the overall limiting effect is unstable, and loose restrictions are prone to occur, which reduces the tightness of the connection between the side panels and the base plate. In addition, the assembly of multiple side panels increases the difficulty of installation, resulting in a waste of time and poor use effect. Utility Model Content

[0010] Technical effects and advantages of the utility model:

[0011] 1. The utility model can quickly install the anti-static cover on the upper side of the substrate by combining the convex strip and the strip-shaped convex groove.

The cooperation with the antistatic cover 2 can form a closed combination, so that the components on the substrate 1 can be wrapped inside to achieve the effect of closed protection. The antistatic cover 2 has a longitudinal positioning groove 6 on the side where the front and rear side panels are in contact with each other. The front and rear sides of the antistatic plate 5 are fixed with positioning strips 7 combined with the positioning groove 6. The installation position of the antistatic plate 5 can be limited by inserting the positioning strips 7 into the positioning groove 6. A connecting groove 8 is opened on the side where the substrate 1 and the lower side of the antistatic plate 5 are in contact. A connecting strip 9 combined with the connecting groove 8 is fixed on the lower side of the antistatic plate 5.
