Emerging Challenges in Smart Glass Quality: Measuring and 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 adjustable (switchable) and electrified “smart glass” technologies, automakers are looking to use these surfaces for a wide array of new functions and applications.

Windows and display surfaces throughout the vehicle are critical for driver and passenger visibility and safe operation. Already, automakers are setting strict quality parameters that smart glass manufacturers must follow to ensure the integrity of embedded glass panels. As automotive glass designs become more complex, powerful visual inspection equipment is needed to detect fine details and defects in glass layers and displayed images.

This webinar features a case study of etched patterns in a smart glass edge-lit sunroof, the manufacturer’s quality challenges, and the approach used to implement an effective inspection solution.

Listen learn about:

  • The types and functional characteristics of smart glass technologies including passive (photochromic, thermochromic) and active (electrochromic, polymer dispersed (PDLC), and suspended particle device (SPD)).
  • The different smart glass applications and how they are being implemented in current and next-generation vehicles.
  • Common defects introduced in the production of smart glass components and how to detect and measure them.
  • Essential characteristics of inspection equipment for automotive glass and displays, featuring a customer case study and measurement examples.
