Abstract

The present disclosure relates to a display device, a display panel and a driving circuit, and a driving method. The display panel includes a driving backplane and a light emitting device layer, and the driving backplane includes multiple pixel driving circuits, the light emitting device layer includes multiple light emitting units distributed in an array, the light emitting unit includes multiple light emitting devices stacked in a direction away from the driving backplane, and light emitting devices other than a light emitting device closest to the driving backplane in a direction perpendicular to the driving backplane are transparent devices; and in the same light emitting unit, at least part of the light emitting devices are coupled to the pixel driving circuits for emitting light under driving of the pixel driving circuits, and at least two light emitting devices in the same light emitting unit have different light emitting materials.
