Answer: No problem. Firstly, please kindly send us your specification/ drawing paper

If you have not the specification, you can also provide your samples; we will recommend the suitable one

if it is standard products. Or we can customize for you based on your own requirement.

2.This LCD is just what we want, but it is big size, do you have any smaller size? And the display content need to be changed a little.
Answer: For the segment type LCD module, if you need modify the outline size or display content,

a new LCD glass module is need. We have to open new tooling for you.

3. This LCD display is HTN type, but I want STN type,can you make?
Answer: That’s all right . we can change for you as per you request.

4. I want customize a new LCD module. Can you do?
Answer: Yes, we can. Please send your drawing paper. If you have not, please advise me the outline size

of the LCD display, display information( Glass thickness, Polarizer, Display Type, Connector mode,
Storage Temp. Operating Temp. Supply Voltage, Viewing direction, drive condition), we can customize for you.

5. What is leading time for tooling?
Answer: General speaking, it will cost 15 to 25 days after drawing paper confirmation and tooling charge payment,

we can report you the exact time when you confirm the drawing paper.

6. Can you send us samples for checking?
Answer: Yes,. Samples order is available.

7. What is the Leading Time?
