Abstract
A light-emitting device driving circuit including a light emitting device, a delivery capacitor, a driving transistor, a reset circuit, a compensation circuit, and a data circuit is provided. The delivery capacitor is electrically connected to a low-level voltage. The driving transistor is configured to drive the light-emitting device according to a driving voltage received from a driving voltage line higher than that of the low-level voltage. The reset circuit is configured to determine whether to electrically connect the light-emitting device to the first node. The compensation is configured to receive a reference voltage higher than the low-level voltage to control a gate voltage of the driving transistor through a second node. The data circuit is configured to receive a data voltage to determine whether to electrically connect the data voltage to the compensation circuit and whether to electrically connect the data voltage to the delivery capacitor.
