Abstract
Provided are a light-emitting panel, a driving method of a light-emitting panel, and a display device. The display panel includes multiple light-emitting units, multiple first switch units, and a constant-current circuit. The light-emitting units are disposed on one side of a substrate and are arranged in an array along a first direction and a second direction. A first terminal of a light-emitting unit is electrically connected to a first supply voltage terminal. A second terminal of the light-emitting panel is electrically connected to a respective first terminal of a first switch unit. The control terminal of the first switch unit is electrically connected to a scan signal line extending along the first direction. A second terminal of the first switch unit is electrically connected to a data signal line extending along the second direction. An output terminal of the constant-current circuit is electrically connected to the data signal line.
