Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal display screens, in particular to a liquid crystal display screen capable of resisting static interference. Background Art
[0002] Liquid crystal displays occupy a core position in today's increasingly popular electronic products. However, they also face some significant challenges. First, due to their special physical structure, existing liquid crystal displays are susceptible to electrostatic interference. This electrostatic interference can cause the image display to bend, blur or even distort, greatly affecting the display effect of the display and the user's viewing experience. What's more serious is that continuous electrostatic interference may also cause the display to fail, posing a serious threat to its stable operation. In addition, liquid crystal displays generate a lot of heat when working, and the heat dissipation design of some current displays is not ideal. Poor heat dissipation will cause the internal temperature of the liquid crystal display to be too high, which will not only affect its normal working efficiency, but also damage the circuits and components of the display, making the liquid crystal display easily damaged by high temperature. Long-term high temperature environment will greatly shorten the service life of the liquid crystal display and increase the user's maintenance and replacement costs. Therefore, we propose a liquid crystal display that can resist electrostatic interference. Utility Model Content

[0030] Through the above scheme: firstly, the grounding wire 3 is grounded to achieve the grounding of the metal shell 1. The grounding wire 3 provides a basic electrostatic protection measure to ensure that the charge can be effectively introduced into the ground, and then the corona discharger 7 is started to ionize the air into a large number of positive and negative ions through the tip high-voltage corona discharge, and then the positive and negative ions are transported to the two shunt pipes 9 through the two air supply pipes 8, and finally, the positive and negative ions are blown to the outer surface of the liquid crystal screen 2 and the outer surface of the rear cover plate 5 through a plurality of air outlet pipes 10, so that the positive and negative ions can evenly and effectively cover the target area, thereby effectively eliminating static electricity and protecting the liquid crystal display screen from static electricity damage, thereby enhancing the anti-static interference effect of the liquid crystal display screen and preventing it from being invaded by static electricity interference.
