Emerging Challenges in Smart Glass Quality: Measuring & Calibrating LED Edge-Lit Sunroofs

Transparent glass surfaces occupy a huge amount of real estate in the vehicle—a modern car contains an average of five square meters of glass. With the emergence of electrified “smart glass” technologies, automakers need new visual inspection solutions to detect fine details and defects in glass layers and displayed images.

One popular new luxury feature is etched glass sunroofs edge-lit with LEDs. This white paper looks at the various quality challenges for these sunroofs and discusses inspection requirements. It features a customer example of etched patterns in a smart glass edge-lit sunroof inclueding a discussion of the manufacturer’s quality challenges and the approach used to implement an effective inspection solution.
