The tft-lcm liquid crystal display module needs to be maintained during use. When the LCM liquid crystal display module is in use, the power supply is connected and disconnected. The signal level can be input only after the positive power supply is stably connected. Do not apply voltage on the signal line when the power supply is not connected or the connected power supply voltage is not stable, which may damage the IC and circuit in the LCM.

It shall not be used outside the specified working temperature range and shall not be stored outside the storage limit temperature range. If the ambient temperature of the LCM is lower than the crystallization temperature of the liquid crystal material, the liquid crystal will crystallize. On the contrary, if the temperature is too high, the liquid crystal material will become an isotropic liquid and the molecular orientation will be broken. Both of these phenomena will cause the LCM to lose its display function.

When the surface of the liquid crystal display device or LCM liquid crystal display module is fogged, do not work with power on, because this will cause electrode chemical reaction and lead to disconnection;

Maintenance and storage of LCM LCD module: 1. Only isopropyl alcohol or ethyl alcohol can be used to clean the LCM. Other solvents (such as water) may damage the LCM.

2. If it is stored for a long time (e.g. more than a few years), there are the following methods: 1) put it into a polyethylene bag (the most | preferably has an antistatic coating) and seal the mouth; 2) Store between - 10 ° C and + 35 ° C; 3) Put it in a dark place and avoid strong light; 4) Never put anything on the surface; 5) Strictly avoid storage under extreme temperature / humidity conditions.
