DISPLAY APPARATUS INCORPORATING EDGE SEALS FOR REDUCING MOISTURE INGRESS

摘要

This disclosure provides systems, methods, and apparatus for protecting a display device from moisture ingress. A display device can be formed from two opposing substrates. Moisture-impervious walls can be formed around the perimeters viewing areas included on the substrates. The substrates can be brought together such that the perimeter walls align. The substrates can be bonded together by an anodic or eutectic bond. At least one layer of material forming the perimeter walls may be doped, for example with sodium ions, to facilitate the formation of an anodic bond. Alternatively, a layer of metal may be deposited onto the perimeter walls to facilitate the formation of a eutectic bond.

主权项

1. An apparatus comprising:
a first substrate including a first planar surface including a first image viewing area; a first perimeter wall formed around a perimeter of the first image viewing area and extending away from the first planar surface; a second substrate including a second planar surface opposing the first planar surface of the first substrate and including a second image viewing area aligned with the first image viewing area of the first substrate; and a second perimeter wall formed around a perimeter of the second image viewing area and extending away from the second planar surface, the second perimeter wall of the second substrate bonded to the first perimeter wall of the first substrate at a point of contact between the second perimeter wall of the second substrate and the first perimeter wall of the first substrate by one of an anodic bond and a eutectic bond.
