For long-term storage over 40qC is required, the relative humidity should be kept below 60%,
and avoid direct sunlight.
3. Do not touch the connection terminals of the display with bare hand; it will cause disconnection or
4. The modules should be kept in anti-static bags or other containers resistant to static for storage.
5. Only properly grounded soldering irons should be used.
6. If an electric screwdriver is used, it should be grounded and shielded to prevent sparks.
7. The normal static prevention measures should be observed for work clothes and working
8. Since dry air is inductive to static, a relative humidity of 50-60% is recommended.

1. Soldering should be performed only on the I/O terminals.
2. Use soldering irons with proper grounding and no leakage.
3. Soldering temperature: 280qC+10qC
4. Soldering time: 3 to 4 second.
5. Use eutectic solder with resin flux filling.
6. If flux is used, the LCD surface should be protected to avoid spattering flux.
7. Flux residue should be removed.
