Description

technical field

[0001] The invention relates to a liquid crystal pollution detection method and a sampling tool thereof, in particular to a liquid crystal sampling method using a sampling tool. Background technique

[0002] At present, liquid crystal display technology is widely used in general electronic products, such as calculators, electronic watches, mobile phone screens, instruments used in hospitals or screens on digital cameras, etc., liquid crystal displays are based on liquid crystal materials. Because liquid crystal is between solid state and liquid state, it has both liquid and crystalline properties within a certain temperature range, and because of its unique state, it was later named "Liquid Crystal", which is a liquid crystalline substance the meaning of. Therefore, liquid crystal not only has the optical characteristics of solid crystal, but also has the characteristic of liquid flow. The liquid crystal molecules will be affected by the voltage, change the ...
