ARRAY SUBSTRATE AND DISPLAY PANEL

WIPO Patent Application WO/2020/057185

A1

Provided are an array substrate and a display panel. The array substrate comprises: a base substrate, organic electroluminescence units located on the base substrate and arranged in an array, and a photoelectric conversion unit corresponding to each of the organic electroluminescence units, wherein a luminescence spectrum of each of the organic electroluminescence units is composed of a first wave band and a second wave band; the first wave band is determined by an emission peak of the luminescence spectrum and is used for determining the degree of brightness and tone purity of light emitted by each of the organic electroluminescence units; and the photoelectric conversion unit is at least used for converting light, emitted by the corresponding organic electroluminescence unit, in the second wave band, to electrical energy. By means of adding photoelectric conversion units corresponding to organic electroluminescence units on an array substrate, light, emitted by the organic electroluminescence units and unrelated to the degree of brightness and the tone purity, of the second wave band can be converted to electrical energy by the corresponding photoelectric conversion units, and the electrical energy can be used for self-charging, thereby increasing the utilization rate of light emitted by a display panel itself and also saving on energy.
