Organic light-emitting display panel, display method thereof, and display device

The invention discloses an organic light-emitting display panel, a display method thereof, and a display device. The organic light-emitting display panel comprises a plurality of organic light-emitting diodes, a determining module, a switching module, and a driving module. The determining module is used for determining the residual electric quantity of the organic light-emitting display panel. The switching module is used for switching the organic light-emitting display panel to one of a power-saving mode, a low-quality display mode and a high-quality display mode according to the determined residual electric quantity. The driving module is used for respectively supplying a first driving voltage, a second driving voltage and a third driving voltage to the cathodes of the organic light-emitting diodes when the organic light-emitting display panel is in the power-saving mode, the low-quality display mode and the high-quality display mode. Therefore, the display panel is switched to different working modes according to the residual electric quantity of the display panel, thereby reducing the power consumption of the display panel. Moreover, different driving voltages are provided at different working modes, so the problems of display unevenness and residual images of the display panel are solved.
