A video transmission system is disclosed. The video transmission system comprises a multi-drop bus, a first source driving chip, a second source driving chip and a timing controller. The first source driving chip comprises a first source driving circuit and a first terminal circuit. The first terminal circuit is coupled to the multi-drop bus and the first source driving circuit for providing a first terminal resistor. The second source driving chip comprises a second source driving circuit and a second terminal circuit. The second terminal circuit is coupled to the multi-drop bus and the second source driving circuit for providing a second terminal resistor. The timing controller is coupled to the first source driving chip and the second source driving chip via the multi-drop bus.

Video transmission system

A source driver and a method for determining polarity of pixel voltage thereof are provided. The source driver includes a data register unit, a plurality of data groups and a plurality of polarity determining units. The data register unit receives an image data signal and provides a plurality of display data. The data groups have at least two data channels respectively. The data channels are coupled to the data register unit to receive the corresponding display data and provide a plurality of pixel voltages. The polarity determining units are respectively coupled to the data channels corresponding to different data groups, and each of the polarity determining units determines whether to invert polarities of a part of the pixel voltages provided by the coupled data channels according to the received display data of the coupled data channels and previous display data corresponding to the received display data.
