Patent number: 9234101Abstract: Colored metalorganic fluids for electrowetting, electrofluidic, and electrophoretic devices are disclosed. The colored fluid can include a polar or nonpolar solvent including silicon and/or germanium and a modified, oligomeric, or polymeric dye. The dye includes a chromophore attached to a low molecular weight group with molecular weight 10 to 800 or an oligomeric or polymeric chain, which includes silicon and/or germanium. The dye has a molecular weight from 100 to 100,000, solubility in the solvent of at least 5% wt at 25° C., and a dynamic viscosity from 0.5 cPs to 2,000 cPs at 25° C. If the solvent is polar, the fluid has a conductivity from about 0.01 pS/cm to 3000 pS/cm, a surface tension of 15 dynes/cm to 90 dynes/cm at 25° C., and a total content of monatomic ions with radii smaller than 2.0 A and polyatomic ions with radii smaller than 1.45 A less than 500 ppm.Type: GrantFiled: December 16, 2011Date of Patent: January 12, 2016Assignee: Sun Chemical CorporationInventors: Stanislav G.

Patent number: 8854714Abstract: Colored conductive fluids for electrowetting or electrofluidic devices, and the devices themselves, are disclosed. The colored conductive fluid includes a polar solvent and a colorant selected from a pigment and/or a dye. The polar solvent has (a) a dynamic viscosity of 0.1 cP to 1000 cP at 25° C., (b) a surface tension of 25 dynes/cm to 90 dynes/cm at 25° C., and (c) an electrowetting relative response of 20% to 80%. The colored conductive fluid itself can have an electrical conductivity from 0.1 ?S/cm to 3,000 ?S/cm and can have no greater than 500 total ppm of monatomic ions with ionic radii smaller than 2.0 ? and polyatomic ions with ionic radii smaller than 1.45 ?. The colored conductive fluid should not cause electrical breakdown of a dielectric in the device in which it is employed. An agent for controlling electrical conductivity can optionally be added to the colored conductive fluid.Type: GrantFiled: August 4, 2010Date of Patent: October 7, 2014Assignee: Sun Chemical CorporationInventors: Lisa Clapp, Jason Heikenfeld, April Milarcik, Russell J.

Patent number: 8717663Abstract: Colored fluids for electrowetting, electro fluidic, or electrophoretic devices, and the devices themselves, are disclosed. The colored fluid can include a nonaqueous polar solvent having (a) a dynamic viscosity of 0.1 cP to 50 cP at 250 C, (b) a surface tension of 25 dynes/cm to 55 dynes/cm at 250 C, and (c) an electrowetting relative response of 40% to 80%. Such colored fluids further include a colorant selected from a pigment and/or a dye. In another embodiment, the colored fluid can include a non-polar solvent and an organic colorant selected from a pigment and/or a dye. Such colored fluids can be black in color and have a conductivity from 0 pS/cm to 5 pS/cm and a dielectric constant less than 3. The use of the colored fluids offers improvements in reliability, higher levels of chroma in the dispersed state, and the ability to achieve higher contrast ratios in display technologies.Type: GrantFiled: March 15, 2010Date of Patent: May 6, 2014Assignee: Sun Chemical CorporationInventors: Jason C.

Publication number: 20130278993Abstract: A display pixel (10, 50). The pixel (10, 50) includes first and second substrates (12, 20, 60, 62) arranged to define a channel (16, 74). A fluid (26, 76) is located within the channel (12, 74) and includes a first colorant (36, 84) and a second colorant (38, 86). The first colorant (36, 84) has a first charge and color. The second colorant (38, 86) has a second charge that is opposite in polarity to the first change and a color that is complementary to the color of the first colorant (36, 84). A first electrode (22, 66), with a voltage source (32, 78), is operably coupled to the fluid (26, 76) and configured to moving one or both of the first and second colorants (36, 38, 84, 86) within the fluid (26, 76) and alter at least one spectral property of the pixel (10, 50).Type: ApplicationFiled: September 1, 2011Publication date: October 24, 2013Inventors: Jason Heikenfeld, Lisa Clapp, Stanislav G. Vilner, April Milarcik, Paul A. Merchak, Russell J. Schwartz
