    Abstract: A driving method, for a controller in a display apparatus, is disclosed. The display apparatus includes LED strings, scan transistors, current regulators and a power converter. The driving method includes following steps. LED cathode voltages are detected on nodes between the LED strings and the current regulators. When a first LED cathode voltage is equal to a minimal operable voltage of the current regulators and a second LED cathode voltage exceeds the minimal operable voltage of the current regulators, a driving current flowing through the second data channel is adjusted by increasing a pulse current level of the driving current and reducing a duty cycle ratio of the driving current flowing through the second data channel.
