Simultaneous UV embossing method for fabricating two parallel organic layers with different hydrophilicity

We developed a simultaneous UV embossing method to fabricate bank-shaped, two parallel layers with different surface properties in a one-step processing using the mold having loop-shaped protrusions. In conjunction with ink-jet technology, the molded pattern could be used as barrier ribs for particular flat panel displays. We choose the layer materials so that the bottom ink-philic one absorb jetted ink and the top ink-phobic one expel jetted ink. Therefore, the structure prevents ink from staining the barrier ribs’ surface and from mixing between adjacent pixels. The structure could be an effective barrier ribs for manufacturing of color filter of a liquid crystal display or light emitting layer of an electroluminescent display with high throughput.
