Claims49
A composition for the preparation of microcups used in a liquid crystal display which composition comprises a thermoplastics, a thermoset or a precursor thereof and liquid crystals.
A composition for the preparation of microcups used in a liquid crystal display which composition comprises a thermoplastics, a thermoset or a precursor thereof and a speed enhancing comonomer or oligomer.
A liquid crystal display comprising two or more layers of microcup array wherein said microcups are formed from a composition comprising a thermoplastics, a thermoset or a precursor thereof and liquid crystals.
A liquid crystal display comprising two or more layers of microcup array wherein said microcups are formed from a composition comprising a thermoplastics, a thermoset or a precursor thereof and a speed enhancing comonomer or oligomer.
A process for the manufacture of a liquid crystal display of more than one layer of microcup array, which process comprises:
- a) preparing separately two layers of microcup array, each on a conductor film;
- and
- b) laminating one of the layers over the other optionally with an adhesive layer.
A process for the preparation of a liquid crystal display of more than one layer of microcup array, which process comprises:
- a) forming a first layer of microcups on a conductor film;
- b) forming a second layer of microcups on a transfer release substrate;
- c) laminating said second layer over said first layer and removing said transfer release substrate;
- d) optionally forming separately additional layers of microcups on transfer release substrates;
- e) laminating said additional layers over the top layer in a stack of layers already formed and removing the transfer release substrates;
- and
- f) laminating a second conductor film over the top most layer of said stack.
A process for the manufacture of a liquid crystal display of more than one layer of microcup array, which process comprises:
- a) preparing a first layer of microcup array on a first conductor film;
- b) preparing a second layer of microcup array on top of the first layer;
- c) optionally preparing additional layers of microcup array on top of a stack of layers already formed;
- and
- d) laminating a second conductor film on top of the top most layer of microcup array, optionally with an adhesive layer.
