Design of Specific Source Driver for Dot-line Inversion

The new application specific source driver was developed in order to drive the LCD panels with dot line inversion. In this new structure, three latches structure is adopted. With no extra requirement on the application specific LCD controller to implement the display data process, the data driver can fulfil the display data re-arrangement to suit for the dot line inversion. The transistor level simulation of the digital part of the three-latch source driver was done by HSPICE to demonstrate the data re-arrangement.
