    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.

    Abstract: A quantum dot display panel, a manufacturing method thereof, and a display device, which relate to the field of display technology, are provided. In a technical solution provided by the present application, a quantum dot light-emitting layer in a traditional method is transferred from a side of a color filter cover plate to a side of an array substrate, thereby reducing an impact of an alignment deviation caused by an alignment process between the cover plate and the array substrate on the quantum dot light-emitting layer. At the same time, because a pixel definition region is a closed shape formed inside the encapsulation layer, the encapsulation film layer can be omitted on the color filter cover of the quantum dot display panel, thereby achieving a purpose of simplifying manufacturing process.
