Colour, Light and Display Measurement for the Automotive Industry
Solutions for specification and QC throughout the value chain
How measurement technologies are used in automotive manufacturing
Automotive manufacturers use measurement technologies to define, communicate and control visual and dimensional quality throughout development, supplier approval, production and final assembly. Across modern vehicle manufacturing, objective data helps ensure that parts and systems meet specification, align with design intent and remain consistent across production sites and supply partners.
These technologies are used not only to check finished components, but also to support specification, prototype evaluation, process control and quality assurance throughout the manufacturing workflow. By replacing or supporting subjective inspection with traceable measurement data, manufacturers can work to tighter tolerances, detect deviations earlier and reduce the risk of defects reaching later production stages. This is especially important in automotive supply chains, where appearance, fit, lighting performance and display quality all contribute directly to perceived vehicle quality and brand value.
Colour and appearance measurement in automotive manufacturing
From the earliest stages of design and specification, colour measurement systems are used to define the visual appearance of interior and exterior materials using precise, traceable data. This allows OEMs and suppliers to work to the same measurable standards across different plants, materials and components. In production and quality control, spectrophotometers and gloss meters are used to monitor variation, enforce tolerances and maintain consistency across plastics, textiles, leathers, painted parts and effect coatings. In an industry where even small visual differences can affect perceived quality, objective colour and appearance measurement provides a reliable reference point alongside visual assessment.
Display measurement in automotive manufacturing
Display measurement technologies are used to evaluate the quality and performance of in-vehicle displays, HUDs, illuminated symbols and instrument panels. These systems help manufacturers specify and verify parameters such as luminance, chromaticity, contrast, uniformity, mura, pixel defects and viewing angle. In modern vehicles, where displays form a major part of the user experience and interface, this level of measurement helps ensure that prototypes, supplied components and finished systems meet both brand expectations and functional requirements. Measurement can be carried out during development, production testing, incoming inspection, or in-vehicle validation.
Light measurement in automotive manufacturing
Light measurement supports the development and validation of ambient lighting, instrument illumination, backlit controls, headlights, signal lamps and rear lights. Engineers use these technologies to measure luminance, illuminance, colour, spectral distribution and light distribution so that lighting systems deliver the intended visual effect while also meeting safety and regulatory requirements. In production, light measurement systems can be used at component level, module level or within the assembled vehicle to confirm that lighting performance remains consistent from design through to final assembly.
Machine vision and automated inspection for automotive manufacturing
Machine vision systems combine cameras, illumination, sensors and software to inspect components and assemblies directly within the manufacturing environment. In automotive production, they are used for tasks such as surface inspection, assembly validation, component positioning and gap and flush measurement. By analysing visual data automatically and in real time, these systems can detect defects and deviations more consistently than manual inspection alone, helping manufacturers control processes earlier, reduce rework and ensure that components meet defined specifications before moving to the next production stage.
The wide range of materials to be measured, including plastics, paint, textile, leather, glass, and metals, requires selection of the correct solution in terms of measurement geometry and usability.
Automotive manufacturers and their supply chains can benefit from complete solutions for the traceable measurement and control of all elements of automotive display technology and lighting. Our systems utilise measurement technology used in development and production of the consumer electronics industry's most advanced display technology, partnered with software customised specifically to the needs of the automotive industry.
In a showroom environment, the uniformity in appearance has a significant impact on perceived quality and, ultimately, on consumer decision making.
Key Benefits of Measurement Technologies in Automotive Manufacturing
Reduce Costs and Improve Efficiency
By minimising trial and error, subjectivity, rework and rejected components, measurement technologies help streamline development and production processes. Early detection of deviations and objective validation reduces waste of time, materials and resources across the value chain.
Achieve Accuracy Beyond Human Capability
Advanced measurement systems deliver levels of precision, repeatability and speed that cannot be achieved through visual inspection alone. This enables manufacturers to maintain tight tolerances, validate complex components and scale quality control across high-volume production across multiple lines and sites.
Enhance Perceived Quality and Product Value
Consistent colour, lighting and display performance contribute directly to how vehicles are perceived by customers. Measurement technologies ensure that every visual element meets design intent, supporting brand positioning and increasing the perceived value of the final product.
Enable Clear Communication Across Global Supply Chains
Objective, traceable measurement data provides a common language for specifying and validating quality across suppliers, production sites and partners. This reduces ambiguity, improves alignment and supports more efficient collaboration throughout the manufacturing process.
Example Applications of Measurement Technologies in Automotive
Colour Quality Control Across Components and Suppliers
Measurement technologies enable manufacturers to control and validate colour throughout the interior, ensuring consistency from dashboards to headrests. By using objective data, teams can align suppliers, streamline approval processes and prevent costly out of specification colour.
Display and HUD Development and Validation
Advanced measurement systems support the development and optimisation of automotive displays, head-up displays and driver interfaces. Fast, accurate photometric and colorimetric data ensures readability, uniformity and performance across production lines, test environments and in-vehicle systems. Consistent data allows teams to assess each stage of production and installation to find areas for optimisation and to eliminate unnecessary costs.
Paint Process Control and Surface Quality Management
From raw rolled steel through e-coat to final clearcoat, measurement technologies enable manufacturers to monitor and control paint processes at every stage. This ensures consistent surface appearance, high-quality finishes and visual harmony across adjacent panels.
Advanced Display Measurement for Complex Geometries
Specialised systems enable the measurement of large, curved and multi-angle displays used in modern automotive cockpits. These technologies support evaluation of viewing angle performance, luminance and colour consistency across increasingly complex display designs.
Validation of Sensing and Infrared Systems
Measurement technologies support the development and validation of sensing systems such as LiDAR and in-cabin monitoring. By analysing light and radiation beyond the visible spectrum, manufacturers can ensure performance, reliability and safety in advanced driver assistance systems.
