Abstract:
1. A source driver applied to a liquid crystal display (LCD), wherein the LCD comprises a pixel array having pixels each comprising one sub-pixel, and sub-pixel data of the sub-pixel comprises first bit data and second bit data, the source driver comprising: a receiver, which comprises a first receiving unit and a second receiving unit, for receiving the first bit data and the second bit data and outputting the first bit data and the second bit data a line buffer comprising a first register and a second register, which respectively correspond to the first receiving unit and the second receiving unit and is for respectively receiving the first bit data and the second bit data outputted from the receiver; a first transmission path for selectively electrically connecting an output terminal of the first register to an input terminal of the second register; and a second transmission path to be electrically connected to an output terminal of the second register and an input terminal of the first register, wherein, the source driver has a first mapping operation mode, and when the source driver operates in a first mapping operation mode, the second transmission path is disabled; the source driver further has a second mapping operation mode, and when the source driver operates in the second mapping operation mode, the first receiving unit is disabled, the second receiving unit is enabled to receive the first bit data and the second bit data, the second transmission path is enabled to input the first bit data received by the second receiving unit to the first register, and the first transmission path is disabled.
