Abstract

The constant push to reduce prices is forcing display manufacturers to continuously look for cheaper manufacturing methods. One of the main cost drivers in display manufacturing is patterning. The process of manufacturing a modern display includes several steps of patterning which are conventionally done by photolithography. Photolithography certainly delivers the level of quality that is required in modern displays but it requires costly equipment and, being a subtractive process, also considerable chemical infrastructure for handling the developing, stripping and etching steps which follow the patterning. Laser direct imaging, now the predominant patterning method in computer-to-plate (CTP) applications in graphic arts, has already been proposed as a replacement for photolithography in manufacturing LCD color filters and inkjet barrier ribs.The purpose of this paper is to present recent work done by Creo Inc. and our partners that demonstrates additional applications where laser direct imaging could replace photolithography in display manufacturing. Such applications include surface energy patterning, conductor sintering and process-less masks.
