Inside a Custom LCD Build: What It’s Like Working With 4D LCD
From idea to production, here’s what to expect when building a custom TFT-LCD with 4D LCD.
In a world of off-the-shelf parts and copy-paste solutions, finding a truly customisable LCD partner is rare-but critical if you’re building a product that’s meant to last, scale, and stand out.
At 4D LCD, we specialise in creating custom TFT-LCD display modules tailored to your application. Whether you’re a startup prototyping a medical device or an established OEM scaling to global production, our process makes it easy to go from spec sheet to shipment…without the typical headaches.
Here’s what it’s like working with us.
Step 1: Understanding Your Application
It starts with a conversation.
We ask:
- What’s the end product or application?
- Is the display for indoor, outdoor, or wearable use?
- Do you need touch? If yes, resistive or capacitive?
- What’s your ideal interface? SPI, RGB, MCU, MIPI, LVDS?
From here, we determine the best base model and whether we can adjust FPC layout, brightness, pinout, connector, and touch panel to suit your mechanical and electrical design.
Step 2: Custom Spec Proposal
Once we understand your application, we’ll prepare a tailored spec package that typically includes:
- Recommended part number
- Technical drawing with connector layout and FPC dimensions
- Optional specs like touch type, brightness, interface
- Estimated lead time and MOQ
- RoHS and REACH compliance documentation (when applicable)
- Option to flag ISO, medical-grade, or export-related certifications if needed
Need to match an existing part or replace an EOL screen? We help with cross-referencing and backward-compatible alternatives.
Step 3: Prototyping & Samples
Once you approve the specs, we move to sample production.
You’ll receive:
- Fully functional samples (standard or modified)
- Datasheets and drawing files
- Testing support as needed
This is your chance to test for fit, form, and function.
Step 4: Production Planning
We work with your production schedule and offer:
- Flexible MOQ depending on model and customisation level
- Bulk or individual packaging (anti-static, foam insert, labelled boxes)
- Regular forecast coordination to avoid delivery gaps
Need logistics support? We can ship from Australia, or Hong Kong, based on your warehouse or assembly location.

Real Customer Feedback
“We had been struggling to fit standard displays into a compact enclosure. 4D LCD customised the FPC and pinout, and now it fits perfectly– no need to redesign our housing.”– Lead Hardware Engineer, EU-based Automation Company
