Optics
Processing        

  The DisplayCheck technology provides optics and processing that are matched to the inspection tasks. Just as a professional photographer would never think of using the same lens for both landscape and close-up pictures, the DisplayCheck solution provides optics that best match the type of defects that need to be detected.

Shown at the left is an SxGA LCoS device being inspected for defects with light filtered and polarized to match the end application.

This approach allows for fast and accurate macroscopic measurements of the entire microdisplay in a single image rather than multiple images and allows for a range of microscopic resolutions to best match defect characteristics.

We have proven this approach on many microdisplay types (reflective, transmissive, and emissive) and are extending this to additional display technologies. We are also looking at new optics and processing solutions to improve the overall system capabilities.
