  • METHOD FOR IMPROVING IMAGE STABILITY OF ELECTROPHORETIC FLUID
    Publication number: 20150185509
    Abstract: The present invention is directed to a display fluid comprising composite pigment particles dispersed in a solvent. The composite pigment particles may exhibit dual functions, that is, they may provide a color to a display device, and also modify the rheology of the fluid without affecting the image switching speed.

  • CHARGED PIGMENT PARTICLES FOR ELECTROPHORETIC DISPLAY
    Publication number: 20130244149
    Abstract: The present invention is directed to a charged pigment particles useful for the electrophoretic fluid. The present invention describes how the charge property of the charged pigment particle may be controlled. By adjusting the charge property of the charged pigment particles to a suitable level for an electrophoretic display system, a faster switching speed, a higher contrast ratio and better image bistability may be achieved.
