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 Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies.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.)
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.
Emissive OLED, microLED (μLED), and miniLED are emerging as the next wave of technology in the display market. This is exciting because these displays promise improved display performance and visual appearance with greater efficiency than other display technologies, thanks to their individually emitting pixel elements. However, high costs due to material prices and manufacturing yield issues have hindered widespread technology adoption for these displays.
Display uniformity is important for visualization of digital information, but perhaps nowhere is this more critical than in industries where displays are relied upon for vehicle operability and safety. Automotive display quality is rigorously tested to ensure visibility—not only to safeguard a positive brand perception, but to comply with industry regulations.
From LCD to OLED to QLED, displays of all kinds are subject to a range of defects introduced either at their component-level or as a result of errors during production. Because no production process can guarantee consistency for every single display produced, quality testing for every display on the line is critical.
OLEDs (Organic Light-Emitting Diodes) are emerging as the next wave of technology in the flat-panel display market. This is exciting because OLED displays promise improved display appearance for both smartphones and large-format TVs at lower cost and power than other display technologies.
Organic light-emitting diodes (OLED) and microLEDs (μLED) are emerging as the next wave of technology in the display market. Display screens based on these emissive layers promise improved performance and visual appearance with greater efficiency than other display technologies, thanks to their individually driven pixel elements.
In movies, we've all seen the dramatic air combat sequence where a pilot uses guide lines to zero in on a target before firing a weapon. Those on-screen guides are a head-up display (HUD), so called because the pilot doesn't have to look down at an instrumentation panel.
The reality of foldable smartphones has been lingering just over the horizon for a few years now, with hints and rumors circulating, prototype models popping up, competitors jockeying for position, and buzz about product launches that haven’t quite come to fruition yet. But it looks like 2019 might finally see foldable smartphones on the market. In just the last few months:

Join a webinar organized by the editors of Tech Briefs Media Group and hosted by several experts in the machine vision field (including Radiant Vision Systems Vice President of Sales and Marketing, Hubert Kostal). Live broadcast August 23 at 9AM PDT (12PM EDT).
Human perception is the ultimate standard for determining the visual quality of a device. However, the use of human inspection as a quality control method for development or production of devices is problematic because of the statistical variation between observers.
Radiant technologies are thoughtfully engineered to achieve the fastest, simplest, and most accurate measurements of light, color, and surfaces. Imaging colorimeters and photometers leverage scientific-grade CCDs, high resolution, low noise, and factory calibration to ensure consistency of data across R&D to production. Utilizing photopic filters, Radiant cameras acquire absolute luminance and color information to qualify devices against human visual perception.
