In the traditional LCD injection method, the cell will be vacuum filled by capillary attraction after the two glass substrates are assembled. Such injection method has the drawbacks of wasting time and LC material. The newly introduced ODF method is to drop the LC directly on the glass substrate prior to the assembling of the two substrates.

This innovative method can save a great deal of time and LC material that has a competitive edge particularly for large size panel. For example, it requires about 5 days to fill the LC for a 30 inches panel according to the traditional method, but it only needs 5 minutes by adoption of the ODF method. Thereby the consumption of LC material can be reduced to approximately 40% as compared to the traditional method.
