LCD Display Knowledge Base (FAQ)

Q1: What is DFSTN?

A: DFSTN stands for Double Film Super Twisted Nematic. It's a type of monochrome LCD with enhanced contrast and wider viewing angles compared to standard STN.

Q2: What does COG mean?

A: COG (Chip On Glass) is a packaging technology where the driver IC is directly bonded to the glass of the display, making the module thinner and more integrated.

Q3: Can I customize the interface or shape?

A: Yes, we support OEM/ODM customization, including interface options (SPI, I2C), FPC shape, backlight color, and more.

Q4: How long does production take?

A: For standard products: 3–7 working days. For custom products: Typically 15–25 working days, depending on design complexity.

Q5: What makes your factory reliable?

A: We integrate MES systems to manage quality from incoming materials to outgoing inspection. Certifications like ISO9001, ISO14001 and Hi-Tech Enterprise status confirm our strength.
