Frequently Asked Questions
I want an LCD display with 8 digits and outline size of 65×30×2.8mm. Is this possible?
Yes, we can accommodate this request. Please provide your specifications or drawings. If you don't have technical drawings, you can send samples, and we'll recommend suitable standard products or customize according to your requirements.
This LCD is what we need, but the size is too large. Do you have smaller sizes available?
For segment type LCD modules requiring size modifications or display content changes, we'll need to create a new LCD glass module, which involves opening new tooling.
This LCD display is HTN type, but I need STN type. Can you manufacture this?
Absolutely. We can modify the display type according to your specific requirements.
Can you customize a new LCD module for our application?
Yes, we specialize in custom LCD modules. Please provide your drawings or specifications including outline size, glass thickness, polarizer type, display type, connector mode, temperature ranges, supply voltage, viewing direction, and drive conditions.
What is the typical lead time for tooling development?
Tooling typically requires 15-25 days after drawing confirmation and tooling charge payment. We'll provide exact timelines upon drawing approval.
Can you provide samples for evaluation?
Yes, sample orders are available for quality verification and testing.
What are your standard lead times for production?
For standard products in stock, lead time is one day after payment. For mass production of custom items, lead time is approximately 15-30 days. We'll notify you promptly if we can complete orders ahead of schedule.
