Abstract
The invention is directed to compositions of display cell structure and electrode protecting layers for improving the performance of display devices. The composition comprises a polar oligomeric or polymeric material having a glass transition temperature below about 100° C., and the resulting display cells or electrode protecting layer have an average crosslinking density of below about 1 crosslink point per 80 Dalton molecular weight.
Claims24
A display device comprising display cells formed from a composition comprising a polar oligomeric or polymeric material which comprises at least one group selected from the group consisting of nitro, hydroxyl, alkoxy, halo, cyano and sulfonate, wherein said display cells have a resistivity in the range of about 107 to about 1012 ohm cm.
A method for improving the performance of an electrophoretic display comprising:
- (i) forming a composition comprising a polar oligomeric or polymeric material which comprises at least one group selected from the group consisting of nitro, hydroxyl, alkoxy, halo, cyano and sulfonate;
- (ii) forming display cells having an average crosslinking density of below about 1 crosslink point per 80 Dalton molecular weight from said composition;
- and
- (iii) filling said display cells with an electrophoretic fluid.
A method for improving the performance of an electrophoretic display comprising:
- (i) forming a composition comprising a polar oligomeric or polymeric material which comprises at least one group selected from the group consisting of nitro, hydroxyl, alkoxy, halo, cyano and sulfonate, wherein the concentration of said polar oligomeric or polymeric material is no less than about 1% by weight;
- (ii) forming display cells from said composition;
- and
- (iii) filling said display cells with an electrophoretic fluid.
A method for improving the performance of an electrophoretic display comprising:
- (i) forming a composition comprising a polyhydroxy functionalized polyester acrylate or alkoxylated acrylate;
- (ii) forming display cells from said composition;
- and
- (iii) filling said display cells with an electrophoretic fluid.
