Worlds first tft roll printing technology developed by lg display

LG Display has revealed that it is currently developing the world’s very first TFT roll-printing technology that has the ability to replace the photolithography process. The all-new technology will be demonstrated by its developer at the Society of Information Display (SID) 2008 event.

Photolithography, which is also known as optical lithography, is a process used in microfabrication to selectively remove parts of a thin film or the bulk of a substrate. It includes an intricate set of processes, for which huge and costly equipment is a prerequisite. However, by employing the roll-printing technology rather than photolithography a lot of these issues are dealt with more effectively.

The roll-printing technology is expected to render manifold benefits, such as it would help cut down the material and equipment costs, clean room investment costs and also curtail the production time of TFT-LCD. And the best of all, it is an eco-friendly technology that reduces the use of chemicals used in the photolithography process to a great extent and is also applicable to the next-generation, flexible display technology.
