Field-line coupling interference prediction of LCD module in high-power TEA CO2 laser system

摘要：

In high power TEA CO2 laser system, liquid crystal display (LCD) module is a key device for display and control functions. Because of laser’s harsh electromagnetic environment, LCD module coupled to the electromagnetic interference easily, leading to not work normally. This paper analyzed the interference coupling mechanism. On the basis of the analysis results, LCD modules field-line coupling is calculated by Taylor forms BLT equation. The calculation result is verified by experiment. The results show that, due to the field-line coupling, the data line of LCD module existed interference voltage, interference voltage value is 1V. The interference voltage is larger than the LCD modules noise margin. LCD module must shield the interference.
