Frequently Asked Questions
1. I want the LCD display 8 digits and the outline size is 65x30x2.8mm?
No problem. Please send us your specification/drawing paper. If you don't have specifications, you can provide samples; we will recommend suitable standard products or customize based on your requirements.
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 segment type LCD modules, 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 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).
5. What is leading time for tooling?
Generally, it will take 15 to 25 days after drawing paper confirmation and tooling charge payment. We can report 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 Leading Time?
If we have stock for standard products, the leading time is one day after payment. For mass production of special products, the leading time is about 15-30 days. If we can finish earlier, we will report the information in advance.
