Precautions for Use of LCD Modules

Handling Precautions: Advises on handling the glass display panel to avoid damage and injury.
Liquid Crystal Substance: Instructions on what to do if the liquid crystal leaks.
Force Application: Warns against applying excessive force to the display surface.

Handling Precautions
LCD polarizers are delicate and can be easily scratched. Handle with care. If contaminated, clean gently with a soft dry cloth or a cloth moistened with isopropyl or ethyl alcohol. Avoid water, ketone, or aromatic solvents.

Assembly and Static Electricity Precautions
Do not disassemble the LCD Module. Ensure logic circuit power is on before applying input signals. Prevent static electricity damage by grounding yourself and assembly tools, avoiding dry conditions, and being cautious when removing protective film.

Storage Precautions
Store away from direct sunlight and fluorescent light, within 0℃ to 40℃ and ≤80% humidity. Avoid environments with acid, alkali, and harmful gases.

Transportation Precautions
Prevent modules from falling, experiencing shocks, excessive pressure, water exposure, dampness, and sunlight during transportation.
