One Pigment Ink System
Is a variable transmissive film, which, when adhered to glass or plastic, allows for control of the light through the surface. JustTint utilizes a one-pigment system, but drives the ink in new ways versus other ink systems. In JustTint, the black pigments move to the side when a charge is applied to allow a transparent area of the capsule.
Two Pigment Ink System
two pigment electronic ink system is made up of millions of tiny microcapsules, each about the diameter of a human hair. Each microcapsule contains negatively charged white particles and positively charged black particles suspended in a clear fluid. When a positive or negative electric field is applied, corresponding particles move to the top of the microcapsule where they become visible to the viewer. This makes the surface appear white or black at that spot.
Three Pigment Ink System
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 pigment system, in that a charge is applied to the pigments, and to a top and bottom electrode to facilitate movement. However, instead of the use of microcapsules, which are filled with the liquid and sealed.
Four Pigment Ink System
Four pigment ink system is a multi-pigment electronic ink offered in mass production for retail and electronic shelf tag labels. EPDs using four pigment ink system offer the same high-contrast, sunlight readable, low-power performance attributes of our other display types - now with a pop of color.
