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 specification document or drawing. If you don't have
technical drawings, you can send samples and we'll recommend
suitable options or create custom solutions based on your
requirements.
This LCD is what we want, but it's too large. Do you have smaller
sizes? We also need minor display content modifications.
For segment-type LCD modules requiring size changes or display
content modifications, we need to create new LCD glass modules.
This requires new tooling development specifically for your
project.
This LCD display is HTN type, but I want STN type. Can you
manufacture this?
Absolutely. We can modify the display type to STN according to your
specific requirements and application needs.
Can you customize a new LCD module for our application?
Yes, we specialize in custom LCD module development. Please provide
your technical drawings. If drawings aren't available, please
specify the outline dimensions, display information (glass
thickness, polarizer type, display technology, 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 provide exact timelines once
technical drawings are finalized and approved.
Can you provide samples for evaluation and testing?
Yes, sample orders are available for quality verification and
compatibility testing.
What are your production lead times?
For standard products in stock, lead time is one day after payment
confirmation. For mass production of custom orders, typical lead
time is 15-30 days. We proactively communicate if we can complete
orders ahead of schedule.
