FAQ
1.What can 128x64 dots display ?
Answer: 128 dots wide & 64 dots high display is an industry standard that can display images or any size letter or number necessary.
2.What is STN LCD ?
Answer:STN (Super-twisted Nematic) provides a sharper image and wider viewing angle than TN (Twisted Nematic). The cost for STN if approximately 5% higher than TN. STN is an ideal fluid for outdoor products that need to be read at various angles.

3.What is transflective LCD module ?
Answer: The Transflective polarizer is a mixture of Reflective and Transmissive. It provides the ability to read the LCD with or without the backlight on. It will work for all lighting conditions from dark with backlight to direct sunlight which makes it the most common choice.
4.How to store the LCD display modules ?
Answer :Please store the LCD display modules in anti-static electricity container and clean environment.
