Abstract
A display panel, a display device, and a driving method thereof are provided. A light-reflecting layer is disposed under a light-emitting layer of the display panel. When the display panel is under strong light, the light-emitting layer does not work, and the light-reflecting layer reflects natural light to achieve a full-color display. When the display panel is in low light or darkness, the light-emitting layer works, and the light-reflecting layer reflects the light emitted by the light-emitting layer to reduce a working intensity of the light-emitting layer and achieves the full-color display, thereby improving service life and visual effect of organic light emitting diodes (OLEDs).
