A driving chip set includes a master chip and at least one slave chip. In the master chip, a master receiving terminal receives a data signal through a first data transmission interface; a processing unit generates a first partial data signal and a second partial data signal according to the data signal; a master buffer registers the first partial data signal; a master output terminal outputs the second partial data signal through a second data transmission interface. In the slave chip, a slave receiving terminal receives the second partial data signal through the second data transmission interface and it is registered by a slave buffer. The processing unit controls a master driver and a slave driver to output the first partial data signal and second partial data signal to a display panel. The display panel displays an image according to the first partial data signal and second partial data signal.
