Electro-optic display with edge seal
First Claim
Patent Images
1. An electro-optic display comprising:
- a backplane comprising at least one electrode;
a layer of electro-optic material disposed adjacent the backplane;
a front substrate disposed on the opposed side of the layer of electro-optic material from the backplane;
a first protective sheet disposed adjacent the front substrate on the opposed side thereof from the layer of electro-optic material; and
a second protective sheet disposed adjacent the backplane on the opposed side thereof from the layer of electro-optic material,the first and second protective sheets being larger in both dimensions than the front substrate and backplane respectively so as to leave peripheral portions of the first and second protective sheets expending beyond the edges of the front substrate and backplane respectively, the peripheral portions of the first and second protective sheets being secured to each other, thereby sealing the electro-optic display, and the display further comprising a layer of optically clear adhesive between the front substrate and the first protective layer.

Abstract
Various types of edge seals for protecting electro-optic displays against environmental contaminants are described. In one type of seal, the electro-optic layer is sandwiched between a backplane and a protective sheet and a sealing material extends between the backplane and the protective sheet. In other seals, the protective sheet is secured to the backplane or to a second protective sheet adjacent the backplane. The electro-optic layer can also be sealed between two layers of adhesive or between one layer of adhesive and the backplane. Other seals make use of flexible tapes extending around the periphery of the display.
