Precautions for use 12864 LCD module - LCD manufacturer:
When you use this LCD module in product design, please note that the LCD perspective is consistent with the use of the product.
The LCD screen is based on glass. Falling or hitting hard objects may cause the LCD screen to break or break, especially in the corner.
Although the polarizer on the liquid crystal surface has a reflective surface, it should be noted not to scratch the surface. It is generally recommended to use a protective screen of transparent plastic material on the liquid crystal surface.
If the liquid crystal module is stored below the specified temperature, the liquid crystal material will condense and the performance will deteriorate.
If the liquid crystal module is stored above the specified temperature, the molecular arrangement direction of the liquid crystal material will change to liquid, which may not return to the original state.
Beyond the temperature and humidity range, the polarizer will cause peeling or blistering. Therefore, the LCD module should be stored within the specified temperature range.
If the liquid crystal surface will be corroded by dripping water or steam for a long time, it shall be wiped immediately to avoid discoloration of ITO surface.
If it is necessary to clean the surface of LCD screen, wipe it gently with cotton cloth or soft cloth. If you still can't remove it, wipe it after you breathe.
The driving of LCD module shall follow the specified rated index to avoid failure and permanent damage. The application of DC voltage to the liquid crystal material will lead to the rapid deterioration of the liquid crystal material. The continuous application of M signal providing AC waveform should be ensured.
In particular, the power switch should follow the power sequence to avoid driving the latch and DC directly to the LCD.
