Abstract:
The described embodiments relate generally to computing devices including liquid crystal displays (LCDs) and more particularly to methods for attaching a cover glass layer to a structural housing while minimizing an amount of stress transferred through the cover glass layer to the LCD module. A continuous and compliant foam adhesive can be used to bond the cover glass layer to a structural. The compliant bond can absorb and distribute local stress concentrations caused by structural loads, mismatched surfaces and differing thermal expansion rates between various structures and cover glass layer. This can reduce stress concentrations in the cover glass layer that can lead to stress induced birefringence in the LCD cell. In other embodiments, the cover glass layer can be attached using magnets or a tongue and groove design.
