Abstract
There is presented a current driver and a corresponding method for driving a current-controlled component such as a semiconductor light source with a driving current. The current driver includes a current regulator for regulating the driving current, a power circuit, and an input stage. The input stage receives a first signal and a second signal and is operable in two phases. In the first phase, the first signal is used to power the power circuit, and in the second phase, the second signal is used to power the power circuit. The current driver may be implemented in an array of cells in which each cell includes a current driver coupled to a current controlled component. The array of cells may be a part of a display device.
