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...

The display industry's biggest event of the year is SID Display Week, May 22-24 at the LA Convention Center. Come by booth #729 to see live demonstrations of Radiant's photometry-based imaging systems that simulate human visusl perception to ensure the absolute quality of display devices from the inside out. Our systems provide light and color uniformity analysis, pixel-level defect detection, correction processes like OLED demura (Radiant’s uniformity correction method uniquely engineered for emissive OLED pixels). We provide solutions for HUD and sparkle measurement, testing AR/VR displays, LCDs, and MicroLEDs, along with advanced vision systems for precision assembly verification and surface inspection.
