Abstract
A light-emitting circuit includes a first transistor, a second transistor, a light-emitting element, a first switching circuit, a second switching circuit, a first capacitor, a current source, and a third switching circuit. The first switching circuit, the second switching circuit, and the third switching circuit are synchronously turned on or synchronously turned off. This not only controls the current flowing through the first switching circuit through the first capacitor, the second switching circuit and the current source to the third power line, and but also controls the current flowing through the third switching circuit, the second transistor through the first capacitor, the second switching circuit and the current source flow to the third power line. Since the current passes through the first transistor and the second transistor, the current flowing through the light-emitting element is reduced, improving adverse effects of parasitic capacitance and wire resistance to the two transistors.
