Chris Williams from Radiant Vision Systems a Konica Minolta company, chats to Tom Selway at AutoSens in Brussels 2018. Recorded at AutoSens Brussels 2018, the world's leading vehicle perception conference and exhibition, held at AutoWorld Museum, Brussels and coming to the USA in May 2019 at the Michigan Science Center, Detroit.
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.
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:
Human perception will always be the ultimate gauge of quality when it comes to flat panel display appearance. After all, the end user of a smartphone, tablet, PC, and TV is a human – one who will spend a lot of time looking at, and enjoy, or not, interacting with it. Colors that are off, non-uniform appearance, or other defects will result in a poor experience.
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.
When I was a kid I loved to sit in the 4th or 5th row of a movie theater, dead center. It was far enough back that I didn’t have to crane my neck, but close enough to the screen to minimize any peripheral visual distractions so I could become completely absorbed in the world of the movie. I stood next to Scarlett O’Hara as Atlanta burned, and soared through the night air on a bicycle with ET.
In today’s automobiles, versatile high-resolution touchpads have replaced analog gauges and knobs. Modern smart lighting adjusts to changing conditions. Radios have been replaced with multi-function, touch-sensitive infotainment displays. Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies. Head-up displays (HUDs) are becoming an automotive standard.
Early Model-T Ford vehicles didn’t even have a speedometer (their top speed was just 35 mph), but soon after, dashboards began to include multiple gages, indicators, and vehicle controls. (Fun fact: the word ‘dashboard’ originates from horse-drawn wagons and carriages, where a board at the front protected passengers from mud that was ‘dashed’ up by the horses’ hooves.)
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.
This article introduces methods for meeting the requirements of the new SAE J1757-2 standard for head-up display measurement and outlines the advantages of automated measurement systems.
Displays viewed near to the eye create immersive virtual experiences, such as those integrated into AR/VR devices. However, as display images are magnified to fill a user’s field of view (FOV), display defects are also magnified. Radiant provides an application-specific display test solution to meet the unique measurement parameters of NEDs viewed in close proximity through AR/VR headsets and goggles.
The AR/VR lens has a unique optical design specially engineered for measuring near-eye displays (NEDs), such as those integrated into virtual (VR), mixed (MR), and augmented reality (AR) headsets. The lens design simulates the size, position, and field of view of the human eye. Unlike alternative lens options, where the aperture is located inside the lens, the aperture of the AR/VR lens is located on the front of the lens, enabling positioning of the imaging system’s entrance pupil within NED
Augmented reality (AR) falls into the category of “spatial computing”—a merger of digital and physical space. Nowhere does this concept hold greater potential for life-changing applications than in medicine. Use of AR, along with virtual (VR) and mixed reality (MR), in the healthcare industry is projected to reach a global market size of US$ 7.05 billion by 2026, growing at an explosive 28.3% compound annual growth rate (CAGR),1 including hardware and software.
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
Augmented reality (AR) may be hot in the marketplace right now, but it’s nothing new in military aircraft. “It’s been around for nearly 60 years,” says Chris Colston, director of strategic growth at BAE Systems, which built the first head-up display (HUD) for the Blackburn “Buccaneer” aircraft that launched in the late 1950s. “We’ve supplied AR solutions long before that meant anything to the mass market.”1
Head-up displays (HUDs) project images onto ambient real-world scenes at infinite focal distances. This unique viewing context poses a challenge for ensuring image visibility and position, especially when it comes to meeting all requirements of established quality standards. Photometric measurement of light and color is equally important as dimensional measurements for image size, distance, location, and integrity in performing comprehensive HUD evaluation to SAE standards for optical quality.
Head-up display (HUD) technology is one of the largest growth areas in the automotive market, and standard measurement criteria are rapidly being defined to evaluate HUD performance for quality and safety. This paper introduces methods for meeting the requirements of the new SAE J1757-2 standard and outlines the advantages of automated measurement systems.In this White Paper, you will learn about:
