Three particle ink system in a Microcup® structure. This ink was engineered specifically for Electronic Shelf Labels (ESL) and is offered in black, white and red, and black, white and yellow. This ink system works similarly to the dual particle system, in that a charge is applied to the particles, and to a top and bottom electrode to facilitate movement. However, instead of the use of microcapsules, this system utilizes Microcups®, which are filled with liquid and sealed.
