摘要： The present invention relates to a method for operating an LCD device, and more particularly to a method for generating frame-start pulse signals commanding the execution of specific functions inside a source driver chip of the LCD device. Since the disclosed method generates start pulse signals commanding the execution of specific functions inside the source driver chip instead of input from the outside, fewer input pins for inputting the frame-start pulse signals are needed. Also, the method can remove input lines for inputting the frame-start pulse signals when the source driver chip is mounted on a print circuit board.

摘要： Provided is a source driver of a liquid crystal display for reducing electromagnetic interference (EMI), in which when a latch latches data of each channel and outputs the latched data, the data of each of the channels is sequentially distributed and outputted with a predetermined time difference or every bit, using an input driving signal, thereby reducing the EMI. In the source driver, after a first latch unit latches image data of each channel, a second latch unit sequentially latches the data of each of the channels with a time difference or every bit, using input driving signals delayed and outputted through a plurality of delays. Accordingly, when an output buffer of the source driver outputs a data signal, the data signal is sequentially delayed with a time difference and then outputted, thereby reducing the EMI.
