Abstract
A method of forming a color filter is provided. The method includes providing a mixture of a color filter material and a compressed fluid; providing at least a partially controlled environment for retaining a substrate, the at least partially controlled environment being in fluid communication with the mixture of the color filter material and the compressed fluid; providing a shadow mask in close proximity to the substrate retained in the at least partially controlled environment; and chargably releasing the mixture of the color filter material and the compressed fluid into the at least partially controlled environment, wherein the color filter material becomes free of the compressed fluid prior to contacting the substrate at locations defined by the shadow mask thereby forming a patterned deposition on the substrate.
