TFT-LCD and flat panel displays have become larger in size and emerged as mainstream, replacing a cathode ray tube. Asian countries including Japan are leaders in the display industry. ULCOAT provides numbers of large mask blanks which are essential lithography materials in the production of FPD and has gotten a high reputation in the FPD market. Larger size plates need automation production lines to achieve higher quality and more volume. We have years of experience with automation technology for such plates.
