AI Technical Summary

Technical Problem

The isolation pillars in the hole area of the display substrate are susceptible to electrochemical corrosion, which can cause moisture to enter the display area and form black spots, affecting the display effect. At the same time, the hole area occupies a large area.

Method used

Different types of isolation pillar designs are adopted, including Type I and Type II isolation pillars. By adjusting the length of the isolation pillars and the thickness and distribution of the insulation filling structure, the arrangement of the isolation pillars is optimized to reduce electrochemical corrosion and reduce the area occupied by the orifice.

Benefits of technology

It effectively prevents electrochemical corrosion, reduces moisture ingress, improves display quality, and optimizes space utilization in the hole area.
