Frequently Asked Questions
I want the LCD display 8 digits and the outline size is 65x30x2.8mm. Is this possible?
Yes, we can accommodate custom specifications. Please provide your detailed specifications or drawing. If you don't have specifications, you can send samples and we'll recommend suitable products or create custom solutions based on your requirements.
This LCD is what we want, but the size is too large. Do you have smaller sizes? Can the display content be modified?
For segment type LCD modules requiring size modifications or display content changes, we can create new LCD glass modules with custom tooling to meet your specific requirements.
This LCD display is HTN type, but I want STN type. Can you manufacture this?
Yes, we can modify the display type according to your specifications and requirements.
Can you customize a new LCD module for my application?
Absolutely. Please provide your drawing specifications. If you don't have drawings, please specify the outline size, display information (glass thickness, polarizer, display type, connector mode, temperature ranges, supply voltage, viewing direction, and drive conditions).
What is the lead time for custom tooling?
Typically, custom tooling requires 15-25 days after drawing confirmation and tooling charge payment. We will provide exact timelines once your drawing specifications are confirmed.
Can you provide samples for evaluation?
Yes, sample orders are available for product evaluation and testing.
What is your standard lead time for production?
For standard products in stock, lead time is one day after payment. For mass production of custom products, lead time is typically 15-30 days. We will notify you promptly if we can complete orders ahead of schedule.
