INTERNATIONAL SUPPORT Radiant engineering, sales, and application teams partner with our customers to develop solutions at home and across international facilities. Design may occur at one facility, while manufacturing occurs abroad. Radiant works with global brands to develop and deploy thousands of systems worldwide, traveling regularly to support implementation. Radiant offers a two-week delivery for new systems, surpassing the speed of competitive solution providers. GLOBAL OFFICE LOCATIONS Radiant maintains direct sales, engineering, and support offices and personnel throughout North America, China, and Korea. Radiant is also sold and supported in other areas of the world by our sister offices in the Konica Minolta Sensing Business. UNIQUE SOLUTIONS DEVELOPED FOR TODAY’S INNOVATIONS WHY RADIANT? D V V S H Apply Radiant cameras at all stages of production to catch defects before final assembly. Pinpoint errors at the component level: cell/open cell, backlight unit (BLU), LCD module, cover glass, and films or coatings. EAD-UP DISPLAYS ISPLAY PIXEL CORRECTION SAE J1757-2 “Optical System HUD for Automotive” provides examples using Radiant cameras for standard measurement. Radiant cameras measure and calculate correction factors for discrepancies in light output between subpixels in OLED, microLED, and other emissive display technologies. Radiant’s fully-automated HUD measurement solution syncs HUD test images with analyses. SPOTLIGHT: Sparkle Measurement SPOTLIGHT: Demura Evaluate the effect of “sparkle” in anti-glare display layers. The Radiant Sparkle Measurement Method quantifies sparkle using a mean pixel-level luminance variation percentage across the display. This value matches human determinations of acceptable display quality, which can be used to set measurable tolerances for films and coatings. IRTUAL & AUGMENTED REALITY The Radiant “demura” process corrects pixel uniformity in emissive displays. A high-resolution ProMetric system takes a measurement of each display subpixel and calculates the correction factors needed to equalize luminance output. These factors are then applied to each subpixel to adjust output and produce a display with a uniform appearance. Swap Radiant’s standard lenses with a conoscope lens for a cost-effective view angle solution that evaluates display quality as seen from any perspective. Conoscope Lens Plot Types: SPOTLIGHT: FPD Conoscope Lens Radiant offers the leading solution for virtual, augmented, and mixed reality display testing. Evaluate the user experience of near-eye displays using a measurement system that captures visual data at the human eye position. The first system for in-headset AR/VR display testing features an aperture at the front of the lens for full FOV measurement. Type C Polar Coordinates JND is the amount of change over an area that is noticeable to a human observer. Radiant software uses a JND value to detect and grade non-uniform areas of light and color in illuminated displays. This process can be extended to inspection of external device surfaces and cover glass to identify, classify, and grade the severity of unknown defects in unknown locations.

When a display Eyebox Limit reaches final assembly, several materials and processes have already been applied—some defective or damaging. Inspection at each layer stops issues at the source. Pixel Defects Viewed at close proximity, display defects become more apparent, so testing at the human eye position is crucial. With aperture located at the front, Radiant’s AR/VR lens captures the complete display FOV as seen by the user. Detect defects on or under surfaces including scratches, dents, bubbles,
