LCD module in the use and storage process need to pay attention to what? We all know that LCD module is now often used in automotive instrumentation and small appliances and electric vehicle instrumentation and other electronic products above, then our LCD module in the use and in the process of storage what is the need to pay attention to it? Below to popularize.
(1) check the LCD module and product use
Has been using the LCD module, pay attention to the LCD viewing angle and product use consistent, check the direction of installation, you can find in the LCD LCD module drawings in the viewing angle parameters, so as to confirm.
(2) the use of the need to be gently held and put away
When using the use of light, drop or impact with hard objects will cause LCD LCD rupture or crushed, pay special attention to the corners.
(3)Be careful to scratch the surface of the LCD module
As the LCD module surface has a layer of soft texture of the polarizer (inhibit the reflection of the surface layer), should be careful not to scratch the surface, generally recommended in the LCD surface using transparent plastic materials to protect the screen, try to wear finger cots operation.
(4) should be stored in the specified temperature and humidity range
If the LCD module is stored below the specified temperature, the liquid crystal material will condense and performance deterioration. If the LCD module is stored above the specified temperature, the direction of the molecular arrangement of the liquid crystal material will change to the liquid state, and it may not be able to return to its original state. Higher temperatures and humidity ranges can cause polarizers to flake or blister. Therefore, LCD liquid crystal module should be stored in the specified temperature range, if there is a need for -40 degrees as well as high temperatures above 85 degrees can still work normally.
(5) timely treatment of surface stains, keep clean
Such as LCD liquid crystal module surface encounter saliva or drip, should be wiped immediately, to avoid color changes caused by a long time later or leave stains. The use of the environment should try to avoid excessive moisture, water vapor can cause ITO electrode corrosion. When cleaning the LCD surface, you should use cotton or soft cloth to wipe briskly, and still can not be removed, lightly dipped in alcohol after wiping.
(6) use in accordance with the manual operation
LCD liquid crystal module drive should follow the specified rated indicators to avoid failure and permanent damage. Applying DC voltage to the liquid crystal material will cause rapid deterioration of the liquid crystal material. To prevent excessive current damage to the chip, ensure that the power supply is operated in accordance with the specifications.
The above is to give you an introduction to the LCD module in the use and in the process of storage need to pay attention to, I hope to be able to help you.
