Quality & Certifications

Checked at every stage, not only at the end: incoming materials, in-process inspection during assembly, and 100% outgoing inspection before packing.

Quality is checked at every step, not only at the end: incoming glass and polarizer inspection, in-process inspection during assembly, and 100% outgoing inspection before packing.

Certifications

  • ISO 9001, ISO 14001 and ISO 45001 certified management systems
  • RoHS compliant materials

Reliability testing

  • High and low temperature operating and storage tests
  • Temperature and humidity cycling
  • Vibration and drop testing for packed goods
  • ESD and electrical parameter verification

Test reports and material declarations are available on request for your compliance files.

Management systems

Certified, and audited against it

A certificate proves a system exists. What matters to a buyer is whether the system is visible in the records that come with the shipment.

ISO 9001

Quality management system covering incoming material control, process discipline, corrective action and traceability.

ISO 14001

Environmental management: chemical handling, waste from the LCD process, and the controls around both.

ISO 45001

Occupational health and safety management for a production environment that handles chemicals and glass.

RoHS

Restricted substances controlled at material level, with declarations available for your compliance file.

Measurement, not opinion

What the claims are checked with

Batch consistency is the hardest thing to promise in this industry, and the only way to hold it is to measure. Our inspection area runs more than thirty instruments, including:

  • 2D measuring instruments for outline and pattern dimensions
  • Metallographic microscopes for bonding and alignment checks
  • TP linear measuring instruments for glass and module thickness
  • BM-7 luminance meters for backlight brightness and uniformity
  • Automated inspection equipment for volume batches

Ask for a test report

  1. 1

    Incoming material

    Glass, polarizers and driver ICs are checked against specification before they enter production.

  2. 2

    In-process

    P/R inspection, development and PI stages, alignment and bonding checks during assembly — more than ten checks per batch.

  3. 3

    100% outgoing inspection

    Every unit is inspected before packing, with electrical parameters verified against the agreed specification.

  4. 4

    Records with the shipment

    Batch records and a photo report travel with the order, so a question three months later can be answered from documents.

Reliability

Tests we can run against your specification

Tell us the environment the product lives in and we agree the test plan before sampling — not after the first field failure.

Temperature

  • High and low temperature operating
  • Storage range verification
  • Cold-start readability check

Humidity and ageing

  • Temperature and humidity cycling
  • High-temperature soak
  • Polarizer and seal condition after test

Mechanical and electrical

  • Vibration and drop testing for packed goods
  • ESD handling and segment function check
  • Electrical parameter verification per batch

Before you order

Frequently asked questions

The questions buyers ask most before starting a display project. Anything missing? Ask us directly — we answer the same day.

Can you produce a display from a drawing or from a sample?

Yes. Send a DXF, DWG or PDF drawing, or a photo of the display you are replacing together with its dimensions. If you have no drawing at all, we can work from a sketch plus the housing dimensions, and confirm the layout before tooling starts.

What is the minimum order quantity?

Typically 1,000 pcs per model for production orders. For a first project we can supply a smaller validation batch so you can test the display in your product before committing to volume — ask for it in your inquiry.

How long do samples take?

Segment panels normally take 7–10 working days after the drawing is confirmed. Module and backlight projects take longer, usually 10–15 working days, because assembly and light-guide tooling are involved.

What does tooling cost?

Tooling depends on the outline size, the number of segments and the connector, so it is quoted case by case together with the unit price. It is a one-off charge, not a per-unit cost, and the tooling belongs to your project.

Which information do you need for an accurate quotation?

Outline drawing, duty and bias (or the controller you use), operating voltage, temperature range, viewing direction, connector type, annual quantity and required date. Missing items are the usual reason a quotation comes back as a wide price range.

Will you sign an NDA?

Yes, on request and before any drawing is shared. Send us your NDA or ask for ours, and we will return it signed.

How is the display packed and shipped?

Parts are packed in anti-static trays with the batch record, then cartons on pallets. Shipping terms are confirmed with the order — we work with your forwarder or arrange transport from Shenzhen or Shanghai.

Request a quotation

Send your drawing, target quantity and operating conditions. Our engineers reply with a feasibility check, tooling cost and lead time within one business day.

  • Drawing review within 24 hours
  • Samples in 7–10 working days
  • NDA available on request

Optional. PDF, image, CAD (DWG / DXF / STEP / IGES), spreadsheet or ZIP — up to 8 MB. Drawings are treated as confidential and never published; we can sign an NDA before you send them.

Several files or something larger? E-mail them to yangrunelectronic@163.com and mention your company name.
