摘要：
A current generator for supplying or sinking current to/from pixels. The current generator includes a variable power source, a first amplifier having a first input terminal coupled to the variable power source, a sensing resistor coupled between an output terminal of the first amplifier and an external terminal of the current generator, and a second amplifier having a first input terminal and a second input terminal coupled to respective ends of the sensing resistor and an output terminal coupled to a second input terminal of the first amplifier.
