An electronic system capable of controlling a backlight and a backlight adjustment method thereof. The electronic system comprises a portable display device and a host device, wherein in a state that the portable display device is docked on the host device, the host device transmits to the portable display device an inputted backlight brightness value setting information through a I<2>C bus, and the portable display device reads-out a pre-stored brightness value data corresponding to the transmitted backlight brightness setting information, and adjusts the backlight lamp based on the read-out brightness value data. Accordingly, since the portable display device can control the brightness value of the backlight lamp, a user's inconvenience caused by a dual control system can be solved.
