Abstract text

An active matrix organic light emitting diode (AMOLED) display device including a panel, a master source driver and at least one slave source driver is provided. The panel has a group of master column pixels and at least one group of slave column pixels. The master source driver receives a reference current and duplicates the reference current to output a master current for driving the group of master column pixels. The at least one slave source driver, coupled to the master source driver or a preceding slave source driver, duplicates the master current or a slave current outputted by the preceding slave source driver as a new slave current and outputs the new slave current for driving the at least one group of slave column pixels.
