     AUO added that key components of the TFT-LCD supply chain will be essential especially with the merger of Quanta Display Inc (QDI) on Oct 1st, where there will be a need for supply of color filter for all generation fabrications. By taking an equity investment in Toppan CFI (Taiwan), AUO optimizes the win-win strategy to leverage Toppan’s leading strength in color filter technology and AUO’s excellent manufacturing capabilities and execution, since the long-term partnership with Toppan Printing.

     With the alliance, two board members of Toppan CFI’s Boards of Directors will be appointed by AUO.

The alliance is anticipated to turn a new page in cross-border collaboration in upstream supply chain in liquid crystal displays
