Abstract
An electro-optic display (100) comprising a backplane (102), a layer (112) of electro-optic material and a protective layer (128) capable of absorbing ultra-violet radiation and disposed on the opposed side of the layer (112) of electro-optic material from the backplane (102), is provided with an edge seal (130). The protective layer (128) extends beyond the layer (112) of electro-optic material, thus leaving a peripheral gap between the protective layer (128) and the backplane (102). To form the edge seal (130) an uncured edge sealing material curable by radiation transmitted by the protective layer (128) is placed in the gap and cured by transmitting radiation through the protective layer (128).
Claims16
A process for curing an edge sealing material in an electro-optic display, the display comprising:
- a backplane;
- a layer of a solid electro-optic material disposed adjacent the backplane;
- and
- a protective layer capable of absorbing ultra-violet radiation and disposed on the opposed side of the layer of solid electro-optic material from the backplane, the protective layer extending beyond the edge of the layer of electro-optic material, thereby defining a peripheral region in which a gap exists between the protective layer and the backplane;
- the process comprising:
- placing in the gap an uncured edge sealing material curable by radiation transmitted by the protective layer;
- and
- transmitting the radiation effective to cure the edge sealing material through the protective layer, thereby curing the edge sealing material and forming an edge seal in the gap.
