Abstract

In order to reduce the manufacturing cost of TFT LCDs and cut down an amount facilities invested, there are many LCD panel makers contributes to convert the current Five-mask manufacturing process into the noble Four-mask fabrication process. We optimized the slit mask to improve the poor process reliability.
