In the traditional display panel manufacturing process,
the polarizer is attached directly after the cell panel is cleaned. If there
are defective products or glass debris attached to the surfaces during cell incoming
or cleaning process, it can lead to material wastage and increased production
cost. To avoid the wastage and increased cost, it is imperative that the
process flow is optimized.
TZTEK's POL pre-AOI detection equipment adopts a high-resolution
and high-transmission speed line-scanning camera, as well as a special line
light source with high luminance and high uniformity, which can reduce the
outflow of defective products caused by back-end deflection. It can realize
online full inspection, reduce manual detection inefficiencies, avoid direct
polarizer attachment after the cell panel is cleaned during the manufacturing
process of traditional display panels, and eliminate material wastage and reduce
production cost incurred due to defective products or glass debris attached to
surfaces during cell incoming or cleaning.
1.By process optimization, direct detection after
cleaning can be realized.
2.There is no direct contact with products using Pre-POL
AOI inspection, thus avoiding product damage.
3.Real-time online full inspection ensures detection stability
and reliability, and prevents defective products from flowing into the polarizer
4.Foreign objects on both sides of the cell, bright
spots, scratches, dust, residual glue, glass chips, edge breakage, and other
appearance defects can be detected
5.Over-detection rate is less than 5% and omission rate
is less than 0.5%
6.Applicable to all sizes of panels
