The relations between size matter and glass substrate of different generations
For those who have heard and wondered about the difference in generation technology, it's really quite simple. The major difference between the different generation fabs is the size of the mother glass, which can be cut into various sizes of panels. The next generation fabs have larger mother glass to either cut into more pieces of panels to increase capacity and lower cost, or produce panels of larger size (e.g. LCD TV displays). From the birth of the industry in early 1990's, the Japanese creators began with generation one (G1) technology processing. The mother glass used in G1 was approximately 30cm x 40cm, equivalent to the size of an open fashion magazine and could make one 15" panel. When Acer Display Technology Inc., which subsequently merged with Unipac Optoelectronics Corp. to form AUO, entered the industry in 1996, the technology had already advanced to G3.5 with the 60cm x 72cm mother glass size. Also, the gigantic mother glass of AUO's G7.5 fab has dimensions of 195cm x 225cm to achieve the optimal cut for flat panels over 40 inches in size to produce large-sized LCD TV displays. The mother glass used in G8.5 is 220 x 250 cm in size, equivalent to the size of a pool table, but the glass thickness is less than 1mm. Therefore, the new generation fabs require higher process technology.
Complete Generation of Fabs and Product Lines
AUO has complete generation of fabs, product lines and product applications, possessing a full range of 3.5G to 8.5G TFT-LCD production lines to allow timely adjustments and support all kinds of application demands.
