Abstract
A method of fabricating color filters on the surface of a substrate involves ejecting fluid droplets onto a transfer surface and transferring the fluid droplets from the transfer surface to the substrate by bringing the fluid droplets on the transfer surface into contact with the substrate. While on the transfer surface the fluid droplets may have their spatial registration adjusted by interaction between the fluid droplets and a periodic pattern on the transfer surface. The fluid droplets may be subjected to various types of post-expulsion treatments on the transfer surface and may be cured on the substrate. Multiple passes may be made to eject the fluid droplets onto the transfer surface and/or to transfer the fluid droplets to the substrate.
