Abstract
An electro-optic display (100) comprises a backplane (102); an electro-optic layer (112) adjacent the backplane (102), the electro-optic layer (112) being smaller than the backplane (102) so as to leave a peripheral portion of the backplane extending beyond the edges of the electro-optic layer (112); and a protective layer (118) disposed on the opposed side of the electro-optic layer (112) from the backplane (102), a peripheral portion of the protective layer (118) extending beyond the edges of the electro-optic layer and being adhered (at 120) to the backplane (102).
Claims23
An electro-optic display comprising:
- a backplane;
- a layer of electro-optic material disposed adjacent the backplane, the layer of electro-optic material being smaller in both dimensions than the backplane so as to leave a peripheral portion of the backplane extending beyond the edges of the layer of electro-optic material;
- and
- a protective layer disposed on the opposed side of the layer of electro-optic material from the backplane, a peripheral portion of the protective layer extending beyond the edges of the layer of electro-optic material, being disposed closer to the backplane than the portion of the protective layer covering the layer of electro-optic material, and being adhesively secured to the peripheral portion of the backplane.
A process for sealing an electro-optic display, the process comprising:
- providing a layer of electro-optic material;
- disposing a backplane adjacent the layer of electro-optic material, the backplane being larger than the layer of electro-optic material so as to leave a peripheral portion of the backplane extending beyond the edges of the layer of electro-optic material;
- disposing a protective layer adjacent the layer of electro-optic material on the opposed side thereof from the backplane, the protective layer being larger than the layer of electro-optic material so as to leave a peripheral portion of the protective layer extending beyond the edges of the layer of electro-optic material;
- disposing the peripheral portion of the protective layer closer to the backplane than the portion of the protective layer covering the layer of electro-optic material;
- and
- adhesively securing the peripheral portion of the protective layer to the peripheral portion of the backplane, thereby sealing the display.
