Display panel and driving method thereof, and display device

A driving method of a display panel, comprising:

• in a first mode, a brightness of the display panel is L1, first light-emitting devices emit light, and second light-emitting devices do not emit light;
• and
• in a second mode, the brightness of the display panel is L2, the second light-emitting devices emit light, or the first light-emitting devices and the second light-emitting devices emit light at the same time,
• wherein:
• the display panel includes:
• a substrate;
• and a plurality of light-emitting devices located on one side of the substrate;
• the plurality of light-emitting devices includes the first light-emitting devices and the second light-emitting devices;
• one first light-emitting device includes a first anode portion and a first cathode portion that are arranged opposite to each other, and a first light-emitting layer located between the first anode portion and the first cathode portion;
• and
• one second light-emitting device includes a second anode portion and a second cathode portion that are arranged opposite to each other, and at least two second light-emitting layers located between the second anode portion and the second cathode portion, wherein:
• a connecting layer is disposed between two adjacent layers of the at least two second light-emitting layers and a light-emitting colors of each of the at least two second light-emitting layers is same in the same second light-emitting device.
