Abstract
A light-emitting device driving circuit is provided. The light-emitting device driving circuit includes a current source, a light-emitting device series and an input-side voltage-stabilizing circuit. The input-side voltage-stabilizing circuit is electrically connected between the current source and the light-emitting device series to provide a driving current. The input-side voltage-stabilizing circuit includes a normally-on transistor, a first resistor and a compensation capacitor. The first resistor is electrically connected to the normally-on transistor. The compensation capacitor is electrically connected to the normally-on transistor and the light-emitting device series.
