Abstract: An embodiment of the present disclosure provides an array substrate and a display panel. The array substrate includes a base substrate, organic electroluminescence components arranged on the base substrate in an array, and a photoelectric conversion component corresponding to each of the organic electroluminescence components. A luminescent spectrum of each organic electroluminescence component comprises a first waveband and a second waveband. The first waveband is determined by an emission peak of the luminescent spectrum, and is used to determine brightness and tone purity of light emitted by the organic electroluminescence component. The photoelectric conversion component is at least used to convert light of the second waveband emitted by a corresponding organic electroluminescence component into electric energy.
