12864 Liquid Crystal module Precautions:

When you use this LCD module in your product design, please note that the LCD perspective is consistent with the product usage.

LCD screens are based on glass and falling or hitting hard objects can cause the LCD to break or shatter, especially in corners.

Although the polarizer on the surface of the liquid crystal has a surface that inhibits reflection, care should be taken not to scratch the surface. It is generally recommended to use a protective screen of transparent plastic material on the surface of the liquid crystal.

If the liquid crystal module is stored below the specified temperature, the liquid crystal material will condense and its performance will deteriorate.

If the liquid crystal module is stored above the specified temperature, the molecular alignment of the liquid crystal material will change to liquid, which may not return to the original state.

Beyond the temperature and humidity range, polarizer can cause peeling or blistering. Therefore, the liquid crystal module should be stored in the specified temperature range.

If the liquid crystal surface encounters saliva or dripping water, it should be wiped immediately to avoid discoloration or stains after a long time, and water vapor will cause corrosion of the ITO electrode.

To clean the surface of the LCD, gently wipe it with a cotton cloth or a soft cloth. If you still can't remove it, wipe it after you breathe.

The drive of the LCD module shall follow the specified rating index to avoid failure and permanent damage. The application of DC voltage to liquid crystal materials will lead to rapid deterioration of liquid crystal materials, and the continuous application of M signals providing AC waveforms should be ensured.

In particular, the power switch should follow the power sequence to avoid driving the latch and DC directly to the LCD.
