AI Technical Summary
Technical Problem
Existing display panels are prone to separation of the array substrate and color filter substrate when dropped or bumped, leading to liquid leakage problems.
Method used
An intermediate layer is provided between the gate insulating layer and the passivation layer, with synapses extending toward the sealant layer, so that the passivation layer and the first alignment film layer extend into the sealant layer, forming an anchoring effect and enhancing the adhesion between the array substrate and the sealant layer.
Benefits of technology
It effectively improves the adhesion between the sealant layer and the array substrate, reduces film peeling or leakage caused by drops, and supports narrower bezel designs.
