Title: SOURCE DRIVER AND SOURCE DRIVING METHOD FOR LIQUID CRYSTAL PANEL HAVING UNEQUAL ROW DRIVING WIDTHS
Abstract:
A source driver (2) and a source driving method for a liquid crystal panel having unequal row driving widths. By arranging an input signal decoding control unit (10) electrically connected to a plurality of data signal output channels (20), coding a data signal output channel start address signal (SET_start) and a data signal output channel end address signal (SET_end) in a package for transmission of a data signal (Data) and sending the data signal output channel start address signal (SET_start) and the data signal output channel end address signal (SET_end) to the input signal decoding control unit (10), the input signal decoding control unit (10) controls the quantity of started data signal output channels (20) according to the received data signal output channel start address signal (SET_start) and the received data signal output channel end address signal (SET_end) so as to regulate the row driving width during each scanning, and can dynamically regulate the row driving width when each row is scanned, and the data signal (Data) is enabled to be just transmitted in pixels which are required to be displayed in each row and is applicable to non-rectangular display, thereby reducing the output power consumption of the liquid display panel; and the source driver (2) for the liquid crystal panel having the unequal row driving widths is designed based on an existing driving framework, and the structure is simple.
