DRIVING CIRCUIT AND METHOD OF TUNING A DRIVING VOLTAGE OF A LIGHT-EMITTING DEVICE UTILIZING A FEEDBACK MECHANISM

摘要

A driving circuit and method for driving a light-emitting device. The driver circuit includes a first bias circuit coupled to an output node of a first light-emitting device for providing a bias current to the first light-emitting device; and a voltage regulator coupled to an input node of the first light-emitting device and the output node of the first light-emitting device for providing a driving voltage to the first light-emitting device and adjusting the driving voltage according to a voltage level of the output node.
