  • Patent number: 8848130
    Abstract: The described embodiments relate generally to computing devices including liquid crystal displays (LCDs) and more particularly to methods for attaching a backlight assembly to a cover glass layer 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 the backlight assembly. 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 another embodiment, a series of rigid plates can be bonded to the cover glass layer and attached to the backlight assembly. Point loads applied from the backlight assembly can be distributed over a larger area due to the resilience of the rigid plates.

  • Patent number: 8821966
    Abstract: A method for manufacturing an image display device includes the step of forming a cured resin layer by interposing a photo-curable resin composition between a protection member and a display-side panel including an image display unit and a frame member and then photo-curing the photo-curable resin composition, with the photo-curable resin composition being disposed across between the image display unit and the frame member. In the manufacturing method, a high-viscosity resin composition having a viscosity of 3000 mPa·s or more and 12000 mPa·s or less is used as the photo-curable resin composition. Alternatively, after a gap between the image display unit and the frame member is sealed with a sealing film, a photo-curable resin composition is interposed between the display-side panel and the protection member.
