Abstract
A low output voltage driver circuit for a light-emitting device is provided according to exemplary embodiments of the present invention. Also, an offset voltage cancellation and/or level shifter is incorporated into the driver circuit to increase the accuracy of the driving current. In addition, an error detection circuit and method are employed in order to adaptively detect the minimum output voltage of the inventive driver circuit.
