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.

Glass is all around us—from building windows to eyeglasses, from automobile windshields to fiber-optic networks. And of course, it's the cover surface material on a vast majority of our smart phones. As displays and mobile devices evolve into flexible, foldable, and rollable form factors to take advantage of the capabilities of OLED, microLED and other new display technologies, glass is evolving as well. Learn more about this remarkable material, and the challenges and future outlook of glass in displays.

These days we’re even more reliant on our screens than Snow White’s queen was on her magic mirror. Considering their importance, the need for quality and clarity of displays—from televisions and smart phones to automobile dashboards to VR headsets—is no fairy tale. Mura is a Japanese word that means unevenness, irregularity, or blemish. In the display industry, this word has been adopted as the name for irregularities and “clouding” effects seen on LCD—and more recently OLED—screens. Learn more about mura types, causes, and what you can do about it.

Advanced imaging solutions—such as scientific-grade CCD-based systems—offer the ability to inspect low-contrast regions in extreme detail for detection and classification of the subtlest variabilities noticeable to the human eye. Although there is an investment to apply advanced systems like these, the ROI of photometry-based systems is justifiable in any operation where the risk of escaped defects and production inefficiency is a great-enough (and costly-enough) concern. Read this blog for 8 inspection challenges and scenarios that justify investment in an advanced photometry-based vision system...
