Abstract
Liquid dispensing includes providing a downwardly inclined slide surface and a carrier liquid dispensing channel that includes an outlet opening on the slide surface. A carrier liquid source is pressurized causing carrier liquid to flow continuously through the outlet opening of the carrier liquid dispensing channel and down the slide surface. A liquid dispenser array structure is provided and includes functional liquid dispensers located on a substrate that is common to the functional liquid dispensers. The functional liquid dispensers include a functional liquid supply channel, a functional liquid source that provides functional liquid, and a drop formation device associated with an interface of the functional liquid supply channel and the slide surface. The drop formation device is selectively actuated to form discrete functional liquid drops in the carrier liquid flowing down the slide surface. The functional liquid is immiscible in the carrier liquid.
