METHOD AND APPARATUS FOR DEPOSITING FILMS |
摘要 |
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. |

1. A method for depositing ink on a substrate, the method comprising:
using a pulsating energy having a first frequency to meter a quantity of ink to a discharge nozzle, the ink defined by a plurality of solid particles in a carrier liquid; receiving the metered quantity of ink at the discharge nozzle and evaporating the carrier liquid from the metered quantity of ink to provide a quantity of substantially solid ink particles; dispensing the substantially solid ink particles from the discharge nozzle and depositing the substantially solid ink particles on the substrate; and wherein at least a portion of the substantially solid ink particles are converted to a vapor phase during discharge from the discharge nozzle, directed to the substrate as a vapor, and condense on a surface of the substrate in substantially solid form.
