Abstract
Apparatus and methods are provided for forming a pixel matrix. The methods include coating a substrate with a pixel matrix material, coating the pixel matrix material with an ink-phobic material, and forming pixel wells in the pixel matrix material and the ink-phobic material. A system for forming a pixel matrix is provided that includes a patterning tool including a laser ablation system operable to form pixel wells in pixel matrix material coated with ink-phobic material. The laser ablation system is operable to form pixel wells in pixel matrix material coated with ink-phobic material in an oxygenated environment so that the sidewalls of the pixel matrix are made to be ink-philic. The invention also includes a pixel well structure in which the top surfaces of the pixel well is ink-phobic and the surfaces of the sidewalls are ink-philic. Numerous other aspects are provided.
