AOI equipment for array processing
The front-end process is a key element of the displaypanel manufacturing process. AOI inspection technology is used in the array panelmanufacturing process to monitor appearance defects; the detection precisionand efficiency play a vital role on product yield and cost. The detection ofperipheral circuits and irregular regions is a major quality control problemfaced by the array sections in display factories.
Project Overview

TZTEK’s AOI equipment for array processing adopts TZTEK’s independently developed Virgo software platform and a unique platform calibration technology. It is suitable for defect detection in array substrates throughout the manufacturing process, and features fast scanning speed and high imaging accuracy (detection precision of 1.0 μm/1.5 μm available).

Program Advantage

TZTEK's unique calibration platform technology supports better image stitching and realizes regional detection. Periodic comparison is adopted for the AA zones, while panel-to-panel comparison is adopted for the peripheral zones

TZTEK’s independently developed Virgo software platform supports the creation of rectangular, circular, semicircular, and other irregular maps

Detection precision of 1.0 μm / 1.5 μm available
