An apparatus for fabricating electronic displays comprises a glass substrate that includes pixel arrays formed on the glass substrate. Individual pixels of the pixel arrays include pixel walls to retain a first fluid, such as oil. The pixel arrays may include an edge seal to retain a second fluid, such as an electrolyte solution, that overlays the pixel walls and the first fluid. A fluid dispenser includes slits that are configured to dispense the first fluid and the second fluid onto the glass substrate at a non-orthogonal angle with respect to the pixel arrays. First portions of the pixel walls extend above second portions of the pixel walls to impart a flow of the first fluid and the second fluid in a direction that the first fluid and the second fluid are dispensed by the fluid dispenser.
