Frequently Asked Questions
1. I want the LCD display 8 digits and the outline size is 65x30x2.8mm. Can you provide this?
No problem. Firstly, please kindly send us your specification/drawing paper. If you don't have 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.
For the segment type LCD module, if you need to modify the outline size or display content, a new LCD glass module is needed. We have to open new tooling for you.
3. This LCD display is HTN type, but I want STN type, can you make?
That's all right. We can change for you as per your request.
4. I want to customize a new LCD module. Can you do?
Yes, we can. Please send your drawing paper. If you don't have one, please advise us 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 the lead time for tooling?
Generally 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?
Yes. Samples order is available.
7. What is the Lead Time?
If we have stock for the standard ones, the lead time is one day after payment. If it is the mass production for special ones, the lead time is about 15-30 days. If we can finish earlier, we will report the information in advance.
