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.
It’s a new year, and (in the popular imagination if not strictly by calendar math) a new decade, making this a perfect moment to look ahead at some of the technology predictions and trends anticipated for 2020 and beyond. Whether these prognostications turn out to be accurate, well, only time will tell.
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.
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 Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies.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.)
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.
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.
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.
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.
Automobiles are getting smarter and smarter—various integrated camera and sensing systems can now help you back up safely, park, avoid a collision, stay in your lane, alert you to a vehicle in your blind spot, and supplement your vision at night, among other features. The Advanced Driver-Assistance Systems (ADAS) that have these capabilities typically use embedded-vision, RADAR, and/or LiDAR-based technology to continuously monitor the environment outside the vehicle.
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.
With all the places you find digital displays these days, evidence suggests it might not be that hip to be square. Displays that break the mold of the standard rectangular, flat-panel design enable a highly organic integration of display features into shapes and sizes that are a much better fit with their use and environments.
