Photolithography is a process used in TFT-LCD fabrication to form patterns on the TFT and color filter substrate and involves a complex set of processes that requires huge and costly equipment.
However, using this new roll-printing technology instead of photolithography, the complex set of processes used to form the required patterns can be proceeded at once.
The report notes that roll-printing technology is expected to help reduce material and equipment costs, clean room investment costs and also shorten the production time of LCDs.
Furthermore, roll printing is an environment-friendly technology that significantly decreases the use of chemicals used in the photolithography process and is also applicable to the next-generation, flexible display technology.
