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.
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.
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.
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 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.
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.
Instrument clusters, symbols, and indicators on the dashboard of an automobile are crucial for the safety and performance of the vehicle. Typical indicators in modern cars include the speedometer and temperature gauges; symbols to indicate if a door is open, a passenger is not strapped in, or the parking break is engaged; a warning light when the gas tank or oil pressure gets low; or the “check engine” light indicating a malfunction.
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:
In this article, we discuss standardization of HUD measurement, and benefits of photometric imaging systems for efficiency, paired with software to enable fully-automated HUD testing to SAE standards.
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.
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.
My blog a few weeks ago took a dive into the world of automotive freeform displays, and discussed how these novel shapes have given auto- and panel-makers the ability to freely design displays into any integration space.
