1. An organic light-emitting display panel, comprising a plurality of light-emitting elements, wherein the organic light-emitting display panel further comprises: a temperature detection and compensation module electrically connected to anodes of the respective light-emitting elements;
the temperature detection and compensation module is configured to: detect a temperature of the organic light-emitting display panel during a pre-set detection period, to determine a temperature compensation voltage corresponding to the organic light-emitting display panel according to the temperature detected by the temperature detection module when it is determined that the temperature of the organic light-emitting display panel is not within a pre-set temperature range, and to apply the temperature compensation voltage as detected to the anodes of the light-emitting elements when the organic light-emitting elements emit light;
the temperature detection and compensation module comprise: a signal input sub-module, a voltage storage sub-module, a data processing sub-module, and compensation input sub-modules having a same number as that of the light-emitting elements, and each of the compensation input sub-modules is connected to the anode of the corresponding one of the light-emitting elements;
the signal input sub-module is connected to the data processing sub-module, the voltage storage sub-module and the compensation input sub-modules, and the signal input sub-module is configured to provide a temperature detection signal outputted by the data processing sub-module to the voltage storage sub-module during the pre-set detection period, and to provide a temperature compensation voltage output by the data processing sub-module to the compensation input sub-modules when the respective light-emitting devices emits light;
the voltage storage sub-module is further connected to a ground end, and is configured to be charged or discharged under a control of the ground end and the temperature detection signal as received;
the data processing sub-module is further connected to the voltage storage sub-module, and is configured to: output the temperature detection signal, to detect a discharge time of the voltage storage sub-module when the voltage storage sub-module is discharged, to determine the temperature of the organic light-emitting display panel according to the discharge time as detected, to determine the temperature compensation voltage corresponding to the organic light-emitting display panel according to the temperature as detected when it is determined that the temperature of the organic light-emitting display panel is not within the pre-set temperature range, and to apply the temperature compensation voltage as determined to the anodes of the respective light-emitting elements through the compensation sub-modules corresponding to the respective light-emitting elements;
each of the compensation input sub-modules is configured to input the temperature compensation voltage as detected to the anode of the light-emitting element connected therewith when the light-emitting element connected therewith emits light.
