Abstract
The present disclosure provides a display panel, a display device and a display method. The display panel includes a base substrate, and an organic electroluminescent device layer, a detection sensor and a color switchable structure which are successively located on the base substrate and are insulated from each other, where the organic electroluminescent device layer includes a plurality of sub-pixels, and the color switchable structure includes sub-units disposed in one-to-one correspondence with the sub-pixels; the sub-units are configured to transmit light emitted by the sub-pixels under the control of applied different signals, or to display light of colors corresponding to the applied signals; and the detection sensor is configured to detect display parameters of the sub-pixels or the sub-units.
