Abstract
An improved method of forming a display is described. The method describes depositing droplets of a display fluid into a sealing solution. The sealing solution seals the droplets of display fluid such that each droplet forms a miniature cell of display fluid. Electrodes address charged particles in the miniature cells to form viewable images for use in a display.
Claims28
A method of forming cells in a display comprising the operations of:
- depositing a liquid fluorocarbon polymer based sealing solution onto a substrate;
- ejecting a droplet of liquid display fluid into the sealing solution, wherein the display fluid is an isoparaffinic solvent based ink, such that surface tension between the liquid display fluid and the liquid sealing solution causes the liquid display fluid droplet to be immersed in the liquid sealing solution;
- and,
- converting at least a portion of the sealing solution from a liquid to a solid such that the solid portion seals the droplet of display fluid.
