FAQ:
1.What is Character or alphanumeric LCDs ?
Character or alphanumeric LCDs: Character displays allow the customer to easily interface with their product. They contain a built in controller/driver combination that displays letters, number and punctuation marks.These displays are available in many standard configurations such as 8x1, 16x2, 20x2, 40x4 and many others.

2.How to minimize the performance degradation of the LCD modules resulting from destruction caused by static electricity?
Please exercise care to avoid holding the following sections when handling the modules.
- Exposed area of the printed circuit board.
- Terminal electrode sections.

3.What is your monthly production capacity ?
Answer: Our monthly production capacity is about one million pieces modules.

4.What are the storage Precautions for character LCD panels?
In case of storing for a long period of time for the purpose of replacement use, the following ways are recommended.
(1) Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it, and with no desiccant.
(2) Placing in a dark place where neither exposure to direct sunlight nor light is, keeping temperature in the range from -30°C to 80°C
(3) Storing with no touch on polarizer surface by anything else. (It is recommended to store them as they have been contained in the inner container at the time of delivery from us.)
