Microdisplays—screens measuring less than two inches diagonally—have been used in applications such projection TVs, smart watches, and near-eye displays (NEDs). Offering very high resolution and brightness coupled with low energy use, they are poised to become more widespread as augmented reality devices, head-up displays (HUDs), and and head-mounted displays (HMDs) are gaining wider use in industries from consumer electronics, to medicine, to the military.

Luminance, illuminance, luminous flux, intensity, brightness...how do we describe the qualities and brightness of light? We explain and discuss the spectrum of electromagnetic waves, including both visible (light) and invisible (e.g., radio, microwave), and how to quantify them with photometric or radiometric measurements.

The prospect of foldable smart phones has been lingering just over the horizon for a few years now, with hints and rumors, protoypes, but no product launches...yet. Will 2019 finally be the year when foldable smart phones reach the market place? What's been taking so long? One of the challenges with foldable screens has been low yields for production of OLED displays—the technology that underlies most foldable devices. Learn more about this challenge and how effective display testing can help improve manufacturing yields and device quality.

Head-up diplays (HUDs) are becoming more common in both automobiles and airplanes, helping to increase safety and reduce distractions for drivers and pilots. In aviation, HUDs have been used for decades in military planes, and are fairly commonplace in large commercial aircraft. But to ensure that HUDs are serving their purpose effectively, there are multiple considerations—design, form factor, symbology, display quality—that have to be carefully addressed.

Tiny assembly defectssuch as a missing screw or misrouted cable can cause big problems in electromechanical devices. From production line waste and rework to latent failures that create warrenty claims and customer dissatisfaction, assembly inspection is critical with today's high-value devices. Learn how photometry-based systems can provide the benefits of automation (e.g., speed and repeatability) with the visual acuity of human inspection for an effective—and cost-effective—assembly verification solution.

The standard analysis for “Black Mura” in automotive displays is widely accepted as the display uniformity measurement criteria for German and many other European automotive OEMs and display makers. Radiant ProMetric® Imaging Colorimeters paired with TrueTest™ Software have been employed for Black Mura standard testing for many years. Radiant has even documented the steps to show how to set up and apply our equipment for Black Mura testing to ensure display uniformity per the German Automotive OEM Work Group and DFF’s specifications.
