Radiant Vision Systems provides visual test and measurement systems that characterize and inspect light and color for quality in display design and automated production. Their inspecting processes and tools are used in LCDs, LEDs, microLEDs, and OLED for flat panel displays, head-up displays, AR/VR, and near to eye displays (NEDs).
KGNOW interviews Optical Software Engineer James Wheeler and Director of Marketing Cathy McBeth of Radiant Vision Systems from the floor of the 2018 Display Week by SID (Society for Information Display). James explains their capabilities including software and hardware packages from head mounted displays for virtual reality to head-up displays for automotive.
In this booth interview with Laser Focus World, Shannon Roberts—Product Manager at Radiant Vision Systems—provides an introduction to the new Near-Infrared (NIR) Intensity Lens in a demo from the floor of Photonics West 2019, San Francisco, CA.
Today's automated solutions enable a range of simple FDP inspection tests that far exceed the capabilities of human inspectors in terms of reliability and objectivity, and yield much greater ROI in application.In this 30-minute webinar, Radiant's Hubert Kostal describes three key benefits of imaging colorimetry for automated inspection of FPDs and offers:
Machine vision inspection has been a boon to many industries—from electronics to packaging to medical devices—by automating repetitive quality inspection tasks. However, traditional machine vision systems simply cannot equal the precision and judgement of human inspectors when it comes to examining low-contrast features, for example, or assessing the scope and severity of defects. Machine vision systems may miss a large percentage of defects in challenging applications like inspec
There’s a lot of data used to characterize electronic displays: resolution, pixels per inch, refresh rate, luminance (nits), pixel pitch, dynamic range, contrast ratio, etc. All this information is meant to help convey the quality of a display. But ultimately, it is the visual experience of human users that will define a display’s performance—and largely determines its success in the marketplace.
You’re in the driver’s seat of your car, glancing at the map on your GPS display to navigate the journey. Meanwhile, your spouse is in the passenger seat, using a display interface in the center console to adjust the temperature and air flow inside the car for everyone’s comfort. And your kids are strapped in the back seat, heads bent together over a shared tablet that’s playing the latest Pixar video release to keep them entertained on the drive.
Today’s electronics manufacturing processes are largely automated. However, final inspection for connected assemblies has lacked an effective automated solution that achieves both highly-repeatable and highly-accurate defect detection. At the final stages of production where internal components are verified before device enclosure, human inspectors remain the primary inspection method.
Are you facing a tough visual inspection challenge with your devices? Looking for a better way to prevent escapes, latent failures, and product returns?
Display technologies continue to evolve rapidly. As the trend continues toward larger, higher-resolution screens, and emerging technologies pose new challenges on the production line, manufacturers need inspection systems that will ensure a flawless product without impacting production speeds.
So much innovation is happening in the fields of augmented reality (AR) and virtual reality (VR) these days, with a wide range of emerging practical applications. AR/VR is revolutionizing everything from medicine to manufacturing to museums. Recent examples include “workers assembling wind turbines at a
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. Learn how to use this tool for quick and efficient measurement of various symbol sets in a backlit panel, button, sign, or instrument cluster.
There is a growing need to reduce time and errors in the manufacture of Flat Panel Displays (FPDs). Quality of the display has quickly evolved into one of the most critical technological differentiators for the end product. Manufacturers, spending a greater portion of the total product cost on the display subsystem, are increasingly demanding best in class test and measurement solutions.
Learn a unique application of Radiant ProMetric® imaging solutions for measuring OLED displays on the pixel and sub-pixel level to calculate non-uniformity and coefficients for pixel-level luminance correction. This process, referred to as “demura,” adjusts the luminance and/or chromaticity of each OLED pixel to produce displays with an entirely uniform appearance.
The demand for perfection in consumer electronics displays is now reaching the automotive market as display technologies such as in-dash LCD screens and heads-up displays are becoming the latest standard feature in today's vehicles. To make the sale and build the brand in the automotive market, perfect displays are required.
See how Radiant's imaging photometers and colorimeters are used at each stage in the production of display devices to detect light, color, and surface defects. By identifying defects as early as possible on the line, our systems facilitate lean operations by improving efficiency, lowering production costs, and reducing material waste, while ensuring absolute quality of devices from display to final mechanical assembly.In this video, you will see:
Display manufacturers continue to automate their production processes, but still rely heavily on human inspectors to ensure visual quality. Measurement resolution and computing technology have reached a point where automated solutions are now able to reproduce - and exceed - the results attained by human inspectors.
Virtual and augmented reality (VR and AR) technologies are already revolutionizing aspects of everyday life, from consumer entertainment to medical care, retail, military operations, transportation, and more. As we move into this new virtual-enabled future, we can gain perspective by remembering where the industry has come from. We hope you enjoy these highlights from the history of virtual reality devices.
