METHOD AND APPARATUS FOR CONTROLLING FILM DEPOSITION
First Claim
1. A system for depositing ink on a substrate, the system comprising:
- a chamber having a quantity of ink, the ink defined by a plurality of suspended ink particles in a carrier liquid;
a discharge nozzle proximal to the chamber for receiving a metered quantity of ink pulsatingly delivered from the chamber by a dispenser, the discharge nozzle evaporating the carrier liquid to form a substantially solid quantity of ink particles; and
a controller in communication with the discharge nozzle, the controller energizing the discharge nozzle to communicate the substantially solid quantity of ink particles from the discharge nozzle onto the substrate.

Abstract
The disclosure relates to a method for depositing films on a substrate which may form part of an LED or other types of display. In one embodiment, the disclosure relates to an apparatus for depositing ink on a substrate. The apparatus includes a chamber for receiving ink; a discharge nozzle having an inlet port and an outlet port, the discharge nozzle receiving a quantity of ink from the chamber at the inlet port and dispensing the quantity of ink from the outlet port; and a dispenser for metering the quantity of ink from the chamber to the inlet port of the discharge nozzle; wherein the chamber receives ink in liquid form having a plurality of suspended particles and the quantity of ink is pulsatingly metered from the chamber to the discharge nozzle; and the discharge nozzle evaporates the carrier liquid and deposits the solid particles on the substrate.

25. A method for providing accurate deposition of ink on a substrate, the method comprising:
-
providing a quantity of ink to a chamber, the ink having a plurality of suspended particles in a carrier liquid; metering at least a portion of the ink delivered from the chamber to an inlet of a discharge nozzle by activating a dispenser; receiving the metered ink at a discharge nozzle, the discharge nozzle having an inlet port and an outlet port; transporting the metered ink from the inlet port to the outlet port of the discharge nozzle forming substantially solid particles; and depositing the substantially solid particles from the outlet port of the discharge nozzle onto a substrate by energizing the discharge nozzle to pulsatingly eject at least a portion of the substantially solid particles onto the substrate. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
