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 Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies.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.
LEDs remain a pivotal light-emitting element in a range of lighting products and displays. For manufacturers of these devices, it is important to evaluate the performance of LEDs and LED-based systems in objective and meaningful ways.
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.
Learn a method for repeatable sparkle measurement. Matt Scholz, Automotive Business Leader at Radiant, presents system specifications and parameters that enable quantification of "sparkle" effects on anti-glare displays according to standard values, with results correlated to human visual perception of display quality.
In this webinar, the Radiant Vision Systems Automotive Team presents effective solutions for evaluating the quality of curved and freeform displays. The team discusses the challenges posed by these displays for measurement, and introduce the latest solutions from Radiant for display registration and flexible measurement setups.
As display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during single-image analysis (necessary for production efficiency). A fractional pixel registration and measurement method improves the accuracy of pixel-level values measured by standard-resolution systems, ensuring effective qualification and demura of high-resolution OLED, miniLED, and microLED displays.
As display resolution and pixel density increase, measuring the characteristics (luminance, chromaticity) of individual display pixels becomes more difficult for current imaging technology. Single-image analysis is important for optimizing efficiency for viable production processes. Imaging systems must continue to accurately measure the increasing number of pixels in a display at once, applying increasingly limited relative imaging resolution.
Imaging systems are highly efficient visual inspection tools, enabling contextual analysis of the complete area of a display, including deviations in luminance, color, and other characteristics. The process of converting light into digital input to create an image, however, is not precisely one-to-one. Imaging sensor types accomplish this conversion process in different ways, each with distinct benefits and limitations.
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.
As display resolution and pixel density increase, measuring the characteristics (luminance, chromaticity) of individual display pixels becomes more difficult for current imaging technology. For instance, the imaging system that I use to measure my display may have an image sensor boasting 29 megapixels (29MP; or around 29,000,000 pixels). Each of these image sensor pixels (tiny light-sensing or photo-sensitive elements) enables me to measure the light emitted from each pixel in a display.
FPDisplay sits with Radiant Technical Director, Li Sun, during the 8th China Information Technology Expo (CITE 2020) in Shenzhen to understand how Radiant continues to innovate in step with—and ahead of—the display market.
From increasing demand for high-resolution televisions, to OLED smartphone commercialization in countries around the globe, to the rise of augmented reality in industry, healthcare, and training—the display market is booming. And the electronics industry hasn’t slowed; continuing to innovate by researching and investing in advanced display technologies, new form factors, and enhanced product features.
Every light source in a vehicle must be measured to ensure its effectiveness for its application. Headlamps must adhere to roadway illumination standards for proper beam shapes, distributions, and intensities for illuminating areas outside the vehicle. Inside the vehicle, LED-backlit components rely on consistent brightness and color—as well as cross-component harmonization—to convey a vehicle’s quality in both function and aesthetic.
This paper discusses 3D sensing and how NIR light is used for facial recognition systems. It explains the importance of measuring radiant intensity of NIR emissions and the challenges of obtaining accurate measurement to ensure the quality of facial recognition systems in devices such as smartphones, laptops, and automobiles. It introduces Radiant's integrated NIR Intensity Lens solution and outlines the solution's advantages for evaluating NIR emitters for use in consumer products.
