The word moiré describes an interference pattern—a form of aliasing—that can appear on images. When using imaging devices to inspect displays, it's usually necessary to remove the moiré pattern as one of the pre-processing steps. A common method is simply to defocus the image. While this removes moiré patterns, it sacrifices image clarity, and is not a good solution for inspecting pixel-dense and emissive displays like OLED and microLED. Learn about Radiant's moiré removal approach that preserves image focus and resolution.

Today, customers expect flawless electronic devices right out of the box. Scratched, dented, and otherwise flawed products can result in damage to your brand reputation and future business. How can you ensure consistent visual quality, i.e., the cosmetic appearance, of delivered products? New photometry-based cosmetic surface inspection approaches are helping spot defects and ensure device quality.

The automotive industry often takes a lead role in proliferating new technologies, and this has never been truer than with displays. New vehicles are incorporating multiple visual display panels, from dashboards and center stacks, HUDs and integrated camera monitoring systems, to individual passenger entertainment screens. Displays are quickly coming to outnumber wheels on standard passenger vehicles, but the requirements for automotive display performance and quality have also never been higher.

Emissive displays like OLED and microLED are on the rise and we expect to see lots of them at SID Display Week 2019. Testing these displays, which have a higher degree of variability than traditional LCD screens, requires new, higher resolution imaging systems. Radiant launches it's newest ProMetric Y43 Imaging Photometer, with a 43MP CCD sensor balanced with other specifications to yeild the most precise, high-quality images.
