At Novara Technologies, our services include designing and manufacturing custom LVDS cable assemblies for reliable, high-performance display connections in demanding applications.
While LVDS technology is well established, the performance of an LVDS display cable depends heavily on how it is designed and manufactured. Seemingly minor decisions early in the process can make a significant difference to signal integrity, reliability and the long-term performance of a product.
In this article, we outline the key considerations that matter most when developing custom LVDS cable assemblies.
Understanding the Application Requirements
Every successful LVDS cable assembly starts with a clear understanding of the application. We work closely with our customers to understand where and how the cable will be used. Factors such as operating environment, available space, expected product lifespan and regulatory requirements all influence the final design.
For example, LVDS display interconnects used in medical devices or automotive systems often require higher levels of reliability, tighter tolerances and full traceability. Industrial or embedded systems may prioritise durability, vibration resistance or extended temperature ranges. Defining these requirements upfront allows us to design a solution that performs consistently throughout its service life.
Cable Length, Routing and Signal Integrity
Cable length and routing have a direct impact on signal quality in low-voltage differential signalling cables. As cable lengths increase, maintaining impedance control and minimising signal degradation becomes more challenging.
At Novara Technologies, we carefully manage the geometry of the conductor, twisting and spacing to maintain consistent impedance across the assembly. We also consider how the cable will be routed within the final product. Tight bends, proximity to power lines or components which make loud noises can all introduce interference if not accounted for during the design stage.
Selecting Connectors and Compatibility
Choosing the right connector is critical for both performance and mechanical reliability. LVDS cable assemblies commonly use connectors from manufacturers such as I-PEX, KEL, JAE and HRS, each offering different pitches, locking mechanisms and durability characteristics.
We help our customers select connectors that match both the electrical requirements and the physical constraints of the product. Connector choice also affects ease of assembly, serviceability and long-term reliability, particularly in applications subject to vibration or repeated mating cycles.
Shielding, Wire Gauge and EMI Control
One of the key advantages of LVDS display cables is their resistance to electromagnetic interference, but this benefit depends on correct shielding and conductor selection. Wire gauge must be matched to the required data rates, cable length and mechanical flexibility.
We offer a range of shielding and insulation options, from foil and braid combinations to specialised materials for high-EMI environments. These design choices help protect signal integrity while ensuring the cable remains flexible enough for space-constrained applications.
Design for Manufacture and Consistent Quality
Designing an LVDS cable assembly that works in theory is only part of the challenge. It must also be manufacturable at scale, with consistent quality across production runs. Our Design for Manufacture experience allows us to optimise designs for efficient, repeatable production without compromising performance.
All LVDS cable assemblies are manufactured to high international quality standards, including ISO9001, ISO13485 and IATF16949 where required. This ensures reliability, traceability and consistency from prototype through to volume production.
A Collaborative Approach to Custom LVDS Solutions
At Novara Technologies, we view LVDS cable assemblies as engineered solutions rather than off-the-shelf components. By working closely with our clients and considering every aspect of the design, from signal integrity to manufacturability, we deliver LVDS display interconnects that meet exact performance, reliability and compliance requirements.
Whether you are developing a new product or enhancing an existing design, our team is ready to support your project with tailored LVDS cable solutions.
