Display edge seal improvement

摘要

Embodiments of the present disclosure relate to liquid crystal displays (LCDs) and electronic devices incorporating LCDs having an organic passivation layer positioned between edge-sealed two substrates. Specifically, embodiments of the present disclosure employ lithographic techniques (e.g., a half-tone mask, diffractive exposure mask, etc.) to remove or not deposit a portion of the organic passivation layer near the edges of the substrates prior to sealing the substrates along these edges. As described herein, this reduction in the thickness of the organic layer near the edges of the device may improve the strength of the edge seal due to reduced strain in the organic layer.

主权项

1. A portion of an liquid crystal display (LCD) comprising:
a first substrate; an organic passivation layer disposed on the first substrate, the organic passivation layer having a thicker middle portion and a thinner edge portion; an adhesive sealant disposed on the first substrate and the thinner edge portion of the organic passivation layer; and a second substrate disposed on the adhesive sealant, wherein the adhesive sealant is configured to seal the first substrate to the second substrate.
