LVDS cable is our factory’s main product line. Roughly 40% of what we ship is LVDS cable assembly going into laptop displays, medical imaging equipment, industrial monitors, and in-vehicle infotainment. We handle every step ourselves — drawing review, connector sourcing from I-PEX, JAE, and KEL, differential pair impedance control, and 100% continuity testing. Standard builds use I-PEX Cabline-CA or Cabline-VS for 30 AWG to 40 AWG work. MOQ starts at 100 sets. First samples in 7–10 days from approved drawings, repeat production in 10–14 days.
What Is an LVDS Cable?
LVDS stands for Low-Voltage Differential Signaling. It’s an interface standard used primarily to transmit high-speed video data between a graphics processor and a display panel, though the signaling method appears in other applications too. The cable carries differential pairs — two wires per channel, with the signal represented by the voltage difference between them. This is why LVDS is resistant to electrical noise, which matters when the signal path runs through a laptop hinge or near a switching power supply.
Key characteristics of a proper LVDS cable:
- Controlled differential impedance — typically 100 Ω ± 10% across each pair. Without this, signal integrity degrades at higher resolutions.
- Pair-to-pair length matching — skew between pairs should stay within tight tolerances, usually 1–2 mm or better for high-resolution displays.
- Shielding — braided shield or aluminum foil to block EMI. Twin-axial (TPA) and single-axial (SPA) variants both show up depending on cost target.
- Flexibility — laptop hinge cables need high-flex life (often 50,000 to 100,000 open-close cycles in qualification testing).
LVDS competes with newer interfaces like eDP and MIPI in the display space, but remains the dominant choice for a huge range of existing product designs and legacy replacement work.
LVDS Connector Families We Build With
About 95% of our LVDS work uses one of three connector families. We stock common variants and can source less-common part numbers on lead time:
- I-PEX (Cabline-CA, Cabline-VS, Cabline-UA, Cabline-UM) — the most common LVDS connector family in modern laptops. 0.4 mm and 0.5 mm pitch. Low-profile designs for slim panel installation. Cabline-CA is our most frequently used series.
- JAE (FI-X, FI-RE, FI-JH, FI-S) — often specified in industrial displays and medical imaging. FI-X series supports 40-pin, 50-pin, and higher pin-count assemblies common in multi-channel LVDS.
- KEL (USL, SSL, SBL) — popular in Japanese display modules and in applications where very fine-pitch connectors (0.4 mm) are needed in compact spaces.
For legacy products we also build with JST, Hirose (DF series), and older TE families on request. If the original connector has gone EOL, we can usually match to a cross-reference part and reproduce the cable with equivalent performance.

Typical Applications
Our LVDS cable production breaks down across these application categories:
Laptop and notebook displays. The largest category by volume. Panel-side connection from the motherboard to the LCD or OLED display, routed through the laptop hinge. Requires high-flex cable capable of 100,000+ open-close cycles.
Industrial and commercial monitors. Kiosk displays, factory HMI panels, POS terminals. Usually lower flex requirement but higher temperature tolerance and stronger EMI shielding due to factory-floor conditions.
Medical imaging equipment. Ultrasound displays, surgical monitors, diagnostic imaging. Demands medical-grade cable standards, ISO 13485 workflow, and sometimes biocompatible jacket materials.
In-vehicle infotainment. Dashboard displays, center-console monitors, rear-seat entertainment. Automotive-grade wire, wide temperature range (-40 °C to +105 °C), and IATF 16949 process when the Tier-1 requires it.
Machine vision and industrial imaging. Camera-to-controller cable in factory automation, AOI systems, and inspection machines. Length stability and impedance control become critical here.
Legacy product replacement. About 15% of our LVDS work is reproducing cables for products where the original supplier went out of business, changed hands, or discontinued the part. Send us an old sample and we reverse-engineer it.
Why SZFRS for LVDS Cable Work
LVDS is our highest-volume product category. The competitive advantage mostly comes from volume experience with a narrow specialty:
Deep connector library. We stock common I-PEX Cabline-CA, Cabline-VS, JAE FI-X, and KEL USL pin counts for faster turnaround on standard builds. Uncommon part numbers are sourced on 1–2 week lead times.
Impedance control. Production operators are trained specifically on LVDS impedance sensitivity. Every new program includes differential impedance verification during first article inspection — we don’t assume the wire spool is within spec.
High-flex cable experience. For laptop hinge applications, we have internal flex-life test fixtures to verify cable construction meets the cycle target before mass production ships. See our capabilities page for equipment details.
Legacy part reproduction. Because legacy replacement is a steady 15% of our volume, we have the internal process for measuring and drawing old samples. First sample usually ready 10–14 days from sample arrival.
IPC/WHMA-A-620 Class 2/3 workmanship. Standard on every order. Class 3 available for medical imaging and critical industrial programs. See our quality and certifications page for compliance details.
Our LVDS Cable Manufacturing Process
- Drawing review and DFM feedback. Our engineers audit the drawing for pin-out, impedance requirement, length spec, and shield configuration. If we spot issues, we flag them before quoting.
- Material sourcing. Twin-axial or single-axial wire matched to the specified impedance. Connectors sourced from authorized distribution (I-PEX, JAE, KEL direct or through approved channels).
- Precision cutting and stripping. Automated machines cut all wires to length within ±0.5 mm tolerance. Differential pair length matching verified on a comparator.
- Termination. Most LVDS connectors use press-fit or micro-terminal insertion — our operators are certified specifically for these compact-pitch terminations.
- Shield termination and grounding. Drain wire, shield clamp, or EMI gasket added per drawing specification. This step is critical for signal integrity in noisy environments.
- Final assembly and overmolding. Housing inserted, strain relief applied, optional overmolded strain relief for automotive or medical jobs.
- Testing. 100% continuity, hi-pot per spec, and differential impedance spot-checks on programs where the customer requires it. First article impedance report available on request.
- Packaging. ESD bag, moisture barrier if spec’d, and per-customer labeling.
Frequently Asked Questions
Can you match a discontinued LVDS cable from just a physical sample?
Yes. Send the old cable. We measure pin-out, wire AWG, differential pair construction, shield type, connector brand, jacket material, and length. Then we produce a drawing for your approval before building. Most legacy reproductions ship first sample in 10–14 days.
What’s the difference between Cabline-CA and Cabline-VS?
Both are I-PEX LVDS connectors. Cabline-CA is 0.4 mm pitch with lower profile, common in slim laptop panels and mainstream consumer displays. Cabline-VS has slightly different mating construction optimized for higher-flex applications and some industrial uses. We stock both, and the choice usually depends on the display panel’s receiving connector.
Do you provide differential impedance test reports?
Yes, on request. Standard first article inspection includes impedance verification on a sample. For production programs requiring per-lot impedance reports, we can add that to the quality package at a modest cost increase.
What’s your MOQ for custom LVDS cable?
100 sets for production. Prototype batches of 10–50 pieces are available with a modest NRE fee. For volume programs above 5,000 sets per order, per-unit pricing drops significantly.
Can you build LVDS cables for high-flex laptop hinge applications?
Yes. For laptop hinge cable work, we use rolled annealed copper, TPU jacket, and specific differential pair geometries to maximize flex life. Cycle life tested in our fixture typically reaches 100,000+ open-close cycles. We can run custom qualification testing for your specific flex profile.
What file formats do you accept for LVDS cable drawings?
PDF, DWG, STEP. A clear drawing should include pin-out diagram, wire AWG and type, differential pair groupings, cable length, shield construction, and jacket material. If you only have partial information, send what you have and we’ll help complete the spec.
Do you ship LVDS cables internationally?
Yes, every day. Europe, the US, India, Southeast Asia, and the Middle East are regular destinations. DDP, DAP, or EXW depending on preference. FedEx, DHL, UPS for samples and small orders; ocean freight for production volumes.
Are your LVDS cables compatible with 4K and 8K displays?
LVDS itself has bandwidth limits that make 4K and higher resolutions typically handled by eDP, V-by-One HS, or other higher-speed interfaces. For those applications, see our eDP cable page. LVDS remains dominant in FHD and some QHD display designs.
