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 corresponding to a first scanning channel is equal to a minimal operable voltage of the current regulators and a second LED cathode voltage corresponding to a second scanning channel exceeds the minimal operable voltage of the current regulators, a voltage drop over one corresponding scan transistor is increased on the second scanning channel.
