Abstract

The disclosure discloses an organic light-emitting display panel, a method for adjusting color temperature thereof, and a display device, and the organic light-emitting display panel includes: an underlying substrate, and a plurality of light-emitting elements arranged on the underlying substrate; each of the light-emitting elements includes a first electrode, a first light-emitting layer, a second electrode, a second light-emitting layer, and a third electrode arranged on the underlying substrate in that order in a light exit direction of the organic light-emitting display panel, where a wavelength of emitted light from the first light-emitting layer is greater than a wavelength of emitted light from the second light-emitting layer; and the first electrode, the second electrode, and the third electrode are connected respectively with different voltage signal terminals.
