Visual inspection solutions for automotive lighting and displays

In today’s automobiles, high-resolution touchscreens have replaced analog gauges and knobs. Modern smart lighting adjusts to changing daylight and road conditions. Center stacks and dashboards set the stage for new freeform and curved display integrations. Traditional headlamps have been superseded by stylish, efficient LED and OLED headlamp assemblies. Head-up displays (HUDs) and back-up cameras are becoming an automotive standard. Today’s cars are becoming our largest smart devices with some of the leading user interfaces.

As a smart device, the visual performance of lights and displays in the vehicle is driven not only by operational and passenger safety, but by expectations for quality in consumer devices. Automakers are challenged to provide an equally exceptional experience in their vehicles, within an even more challenging environment subject to varying temperatures, vibrations, and ambient influences much more severe than what most consumer displays and devices are exposed to.

Photometric measurement systems (for instance, imaging photometers or colorimeters) enable a quantitative, objective analysis of the qualities of light and color in all visual components, and in accordance with a user’s visual experience. These systems evaluate characteristics like the brightness of headlamps and displays, the contrast of virtual images in the HUD on a windshield, the color of backlit symbols on an instrument panel, the distribution patterns of light from lamps to ensure visibility of elements in and outside of the vehicle… Radiant Vision Systems provides a broad portfolio of photometric measurement solutions to ensure design efficiency and control in the production of automotive displays, lighting systems, and illuminated components. Radiant's camera/software systems are helping automakers and suppliers worldwide improve their R&D, quality control, and production operations.

From the vehicle interior to exterior, this video illustrates Radiant measurement solutions for:

  • Console, dashboard, head-up, and e-mirror displays
  • Instrument panels and backlit components
  • Headlamps, taillights, and other lighting systems
  • Facial recognition and driver monitoring using near-infrared light

Radiant’s ProMetric® imaging systems are designed with CIE-matched tristimulus optical filters, which receive light and color in a way that simulates the human eye’s response. Using a Radiant solution, automakers can be sure not only that their systems are objectively qualified for performance, but that the level of quality they achieve in their systems matches what their customers expect, and what they will actually experience.
