PIXEL WALL CONFIGURATION FOR DIRECTING FLUID FLOW FOR FABRICATING ELECTROWETTING DISPLAYS

摘要

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.

1. A display device comprising:
a glass substrate including:
one or more pixel arrays formed on the glass substrate, wherein the pixel arrays include:pixel walls that partition individual pixels of the pixel arrays and at least partially retain a first fluid, anda second fluid to cover the pixel walls and the first fluid, whereinfirst portions of the pixel walls extend above second portions of the pixel walls and are aligned in a first direction to direct a flow of the second fluid toward a second direction.
