Process for Designing Your Display

Quality, Production & Certifications

 

  • In-house LCD Production: We design and manufacture the LCD modules in-house, from glass to backlight. This lets us adjust details quickly and keep continuous production for your models.
  • Quality Control & Lifetime Tests: We test our industrial LCDs for 10 years of service life under typical use. Incoming checks, in-process control and lifetime tests help us keep your displays working in the field.
  • Certifications & Compliance: We run our factory under ISO9001 and use RoHS / REACH compliant materials. If you need quality documents or reports, we can prepare a full package for your project.

Engineering & Customization Services

 

  • Design Review for Your LCD: You can send me your drawing, photo or current LCD part number. We review size, interface and application, then suggest a realistic LCD solution.

 

  • Display & Interface Optimization: We help you choose display type and tune the backlight for your environment. At the same time, we match the interface to your board, so SPI, I²C or parallel all work safely and reliably.

 

  • Electrical Interface Support: We match the LCD interface to your board: parallel, SPI or I²C with safe timing and voltage. You can share your schematic, and we will point out risks before you build hardware.

Frequently Asked Questions

It depends on the LCD type. For many standard LCD modules, we support small MOQ for the first order. For full custom glass or backlight, the MOQ is higher, but we always suggest a cost-effective quantity for you.

For standard LCD modules, the lead time is usually around 4–5 weeks after order. For custom LCD designs, tooling and first samples may take about 3-4 weeks, depending on complexity. After your sample is approved, mass production follows the agreed schedule.

If we can base your design on one of our existing standard structures, sometimes no tooling cost is needed. For full custom glass, backlight or special mechanics, a one-time tooling cost is required. We always explain the tooling items clearly in the quotation before you decide.

Yes, we do this very often. You can send me photos, key dimensions, pinout or a drawing of your current LCD. We will check if we can design a drop-in or improved replacement with stable long-term production.

Most industrial LCD models are designed for 5–10 years of service life under typical conditions. We run lifetime and reliability tests to support this, and keep continuous production for core models. If you need test data for your project, we can share the relevant reports with you.

I mainly support industrial, medical, power, HVAC, instruments and home appliance projects. Most of my customers are from Europe, North America and Asia, working on long-lifecycle devices.
