Abstract: Embodiments of the present invention provide a flat panel electronic device and a current control system thereof. The current control system comprises: a detecting module for detecting a current in a main circuit of the flat panel electronic device; and a control mechanism for reducing a brightness level of a backlight unit of the flat panel electronic device when the current in the main circuit is larger than or equal to a threshold so that the current in the main circuit is reduced to be less than the threshold. The current control system provided by the present invention reduces the current in the main circuit by reducing the brightness level of the backlight unit. Therefore, it is able to reduce the processing time by more than 10 ms compared with the prior art, and the fast and effective response is an important factor for extending the life of the battery.
