Color-mixing bi-primary color systems for displays

A display device comprising:

• at least one pixel;
• a first colorant located within the at least one pixel, the first colorant having a color;
• a second colorant located within the at least one pixel, the second colorant having a color that is complementary to the color of the first colorant;
• and
• an activation mechanism operably coupled to the at least one pixel and configured to apply a force that causes a color change in the pixel.

A method of generating color, the method comprising:

• placing a first pair of complementary colorants in a first mixing relationship in a first sub-pixel;
• placing a second pair of complementary colorants in a second mixing relationship in a second sub-pixel that is proximate to the first sub-pixel;
• placing a third pair of complementary colorants in a third mixing relationship in a third sub-pixel that is proximate to at least one of the first and second sub-pixels;
• and
• applying light to the first, second, and third regions.

A composition comprising:

• a fluid;
• a first plurality of colorants within the fluid, the first plurality of colorants having a first color;
• and
• a second plurality of colorants within the fluid, the second plurality of colorants having a second color, the first and second colors being complements,
• wherein the first plurality of colorants and the second plurality of colorants move differently within the fluid when a force is applied to the fluid.

A method of dosing a display pixel, wherein the display pixel includes a first substrate and a second substrate arranged relative to the first substrate to define a channel having a first volume, the method comprising:

• injecting a second volume of a fluid into the channel, the fluid having a first charged colorant and a second charged colorant that is opposite in polarity to the first charged colorant and the fluid has a first melting point, wherein the second volume is less than the first volume;
• lowering a temperature of the display pixel to less than the first melting point;
• injecting a third volume of a solvent into the channel, the solvent having a second melting point that is lower than the first melting point;
• and
• raising the temperature of the display pixel to more than the first melting point such that the fluid and the solvent mix.
