1. The LCD display should avoid the DC part of the DC voltage driving a car voltage from getting employed no more than probable, along with the greatest ought not go over 50mV.circular lcd display ，When the DC aspect is used for many years, electrolysis and electrode growing older will arise, thereby decreasing the lifestyle
2. The LCD display ought to be protected against uv radiation. Liquefied crystal and polarizers are natural and organic materials, and photochemical reactions and damage will take place under uv rays. As a result, when constructing the liquefied crystal gadget, it should be deemed be it needed to put in an anti- sun filter right in front according to its purpose and utilize surroundings. Light motion picture or other anti ultra-violet techniques should likewise stay away from continuous direct sunlight when using
3. The Digital monitor should be eliminated from becoming eroded by dangerous fumes. Fluid crystals and polarizers are natural and organic materials, and chemical reactions and degeneration exist in the environment of harmful gases. Consequently, solitude actions needs to be used for hazardous gases in use. In addition, following the total machine is assembled, usually do not Retail store within a enclosed container for many years to stop the liquefied crystal and polarizer from getting broken by abnormal power of chemical substance gasoline generated from the plastic material casing and circuit board cleaning up agent.
