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 Traditional headlamps have been superseded by stylish, efficient LED and OLED headlamp assemblies.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. Radiant Vision Systems presents a complete portfolio of measurement solutions to increase efficiency and ease in the design and production of automotive displays, lighting systems, and illuminated symbols. Radiant''s fully integrated measurement systems are helping automakers and suppliers worldwide improve their R&D, quality control, and production operations.

See how Radiant Vision Systems imaging photometers and colorimeters are applied at each stage in the production of display devices to detect light, color, and surface defects as early as possible on the line, facilitating lean operations through improved efficiency, optimized cost and materials, and absolute quality of devices from display to final mechanical assembly.

The INSPECT.assembly™ solution is a fully-integrated inspection station that utilizes a Radiant Vision Systems ProMetric® imaging system, bright field lighting, and programmable software to detect subtle defects on complex assemblies and low-contrast parts and surfaces.

The Auto-POI (Automatic Points of Interest) functionality available in Radiant''s TrueTest™ Software platform enables the automatic application of points of interest on backlit symbols using luminance values and chromaticity coordinates to define measurement thresholds. Once points of interest are defined, users can run pass/fail criteria against new values received, such as new parts entering a production line. Since Auto-POI is set based on light and color values, rather than static regions, symbol sets can accurately be measured regardless of location, position, size, shape, or color without reprogramming the POI parameters.

This video will cover:

• How to use the Auto-POI tool in TrueTest Software
• Measuring luminance and chromacitiy values of unique symbol sets
• Setting luminance and color thresholds to measure specific symbol sets
• Pass/fail analysis for luminance of symbols within symbol sets

Customers of today''s consumer electronics devices expect a flawless product out of the box. Scratched, dented, and otherwise imperfect products result in costly returns and may damage your brand''s reputation and future business. Quality control activities to prevent and detect surface defects rely largely on human inspectors. However, the faster the production rate, more complex the product, or more obscure the defect, the more difficult it is for humans to keep up with throughput demands while adhering to the need for absolute quality. Radiant''s high-resolution, low-noise imaging systems are engineered to measure and detect subtle variations in uniformity across components and surfaces. Our solutions combine the speed and consistency of automation with the discernment of human vision. Using advanced measurement capabilities, Radiant imagers are ideally suited for detecting anomalous features on surfaces and grading these defects based on their location, scope, and severity.

The Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 850 or 940 nm near-infrared (NIR or near-IR) emitters.

Thanks to well-established scientific methods, we can quantify the human eye''s response to light in a mathematical context for use in optical metrology. Light measurement systems like imaging photometers and colorimeters use CIE-matched optical filters and scientific-grade imaging sensors to apply these methods, capturing meaningful data that guide human-centric design and evaluation of many of today''s devices.

In this presentation, Radiant presents foundations of photometry and colorimetry, and introduce photometric technologies that leverage these principles to accurately quantify the human visual response to ensure quality in light and display products.

Topics include:

• How the human eye responds to light and color
• Quantifying color based on CIE tristimulus color-matching functions (curves)
• Technology designed to replicate human visual response
• Optical metrology systems and benefits of imaging for light measurement

MicroOLED, miniLED, and microLED have set off a new wave of technological progress. Because each pixel in these emissive displays is self-illuminating, output differences between pixels may occur, resulting in non-uniform brightness and color across the display. To address this, manufacturers can apply scientific photometric imaging systems in R&D and production to measure display output and correct pixel-level values for visibly perfect display quality.
Radiant''s portfolio of display test & correction solutions is designed for both R&D and high-throughput inspection applications including pixel-level measurement and calibration (demura). Combining ProMetric® Imaging Colorimeters and Photometers with TrueTest™ Software, these systems help to increase efficiency, control production costs, and ensure visual quality of consumer electronics displays from large panels to smart devices to virtual & augmented reality headsets.
