SOURCE DRIVER AND THE DATA SWITCHING CIRCUIT THEREOF

摘要

A data switching circuit is provided, which reduces power consumption of the source drivers when used together with a dot inversion driving method. The circuit comprises a control unit and a switching unit. Wherein, the control unit provides a switching signal. The switching unit has 2N input terminals and 2N output terminals and receives the switching signal. Assume that N is a positive integer and 1<=i<=N. When the switching signal is in a first state, the switching unit connects the (2i-1)^th input terminal and the (2i-1)^th output terminal, and connects the 2i^th input terminal and the 2i^th output terminal. When the switching signal is in a second state, the switching unit connects the 2i^th input terminal and the (2i-1)^th output terminal, and connects the (2i-1)^th input terminal and the 2i^th output terminal.
