This CD-ROM covers oxide-TFT-LCD manufacturing process. In short, it covers oxide-TFT array process, CF (color filter) process, LC (liquid crystal) cell process, and module assemble process.

By contrast, “Manufacturing process of oxide-TFT” is specialized oxide-TFT array process only. Driving device is considered OLED, e-paper in addition to LCD.

If you take an interest oxide-TFT-LCD process, please choose this CD-ROM. On the other hand, if you take an interest oxide-TFT array process only, please choose “Manufacturing process of oxide-TFT”.
