Access to information mainly through display and interactive interface with the electronic technology and electronics integrated rapid development of LCD modules in the smart instrumentation to achieve a mix of graphics and text display, man-machine dialogue to achieve the on-screen menu operation thus graphic LCD module with its small size, low power consumption, the development cycle is short, safe, reliable, flexible, etc., in the smart meter has been more widely used.

The use of liquid crystal
TFT Lcd Modules stirred prior to use infusion before use, adding a chiral agent, a solid crystal, heated to sixty degrees Celsius, and then rapidly cooled to room temperature and stirred well. And in the course can not stand for too long. Especially low threshold voltage of the liquid crystal, the liquid crystal has a low threshold voltage of these different characteristics, so the use of these liquid crystal should note the following:
LCD stir before use, deployment of a good COG LCD Display should immediately put into production use, minimize storage time standing, avoid chromatography phenomenon.
Deployment of a good LCD to be stamped into the shade, and as far as a shift (eight hours) are finished using, use up the LCD need to be recycled after mixing retest voltage reuse. Generally with time, the driving voltage will increase.
LCD bottles drawn from the factory, the original bottle cap shading to save time and reduce exposure to the open air in the time normally exposed to the air for too long, will increase the leakage current of the LCD.
Sink low threshold voltage of LCD tablets empty box is best to pour from the PI solid roast process between LCD, save the stream production time within twenty-four hours in an empty box, irrigation fluid operations typically use a relatively low perfusion rate.
Low threshold voltage LCD seal must be stamped at the appropriate hood, and in addition to the entire irrigation liquid crystal sealing compound during curing period, but also should be kept away from UV source. Otherwise it will appear in the wrong place near ultraviolet and threshold voltage increases to the phenomenon.
LCD is an organic polymer material, easily dissolved in various solvents or other chemicals react with the liquid crystal itself is a good solvent, so the use and storage process to try to stay away from other chemicals.
