Abstract
This invention provides an LED backlight control system and a backlight driver chip used therein. The backlight driver chip used in the LED backlight control system includes two communication connection ports having the same circuit structure and a port control unit. The port control unit is configured to, when receiving a preset waveform signal through either of the two communication connection ports, set that communication connection port as the master communication connection port of the backlight driver chip and set the other communication connection port as the slave communication connection port of the backlight driver chip.
